10x Content

This is a term coined by Rand Fishkin, founder of Moz. 10x content refers to content that is 10 times better than anything else available on the search results for a particular keyword or topic. It focuses on providing exceptional value through comprehensive, well-researched, and high-quality content. A 10x content should be unique, valuable, engaging, and impressive enough to earn shares and links naturally.

301 Redirect

A 301 redirect is a permanent redirect from one URL to another. It is often used when a webpage has been moved or deleted to pass the page’s ranking and traffic to a different URL. This method also helps to prevent users from landing on 404 error pages, thus enhancing user experience and SEO.

302 Redirect

Unlike a 301 redirect, a 302 redirect is a temporary redirect, indicating that a page has been moved temporarily and is expected to be returned. While it does pass some link equity, it is not as effective as a 301 redirect from an SEO perspective.

404 Error

A 404 error occurs when a webpage is not found. This can happen if the page has been deleted or the URL has been changed without a redirect. From an SEO perspective, too many 404 errors can negatively impact user experience and may affect site ranking. It’s important to regularly check and fix 404 errors.

410 Gone

A 410 status code indicates that the requested resource is permanently unavailable. Unlike a 404 error, a 410 error clearly tells search engines that the page has been intentionally removed and will not be coming back, and thus they should deindex the page.

500 Status Code

A 500 status code is a server error indicating that the server failed to fulfill a valid request. This can be due to various reasons like server overload, configuration issues, or programming errors. Regular occurrence of 500 errors can negatively impact a website’s SEO as it affects the user experience and might prevent search engines from properly crawling and indexing the website.


Accelerated Mobile Pages (AMP)

AMP is an open-source framework developed by Google in collaboration with Twitter. It aims to make mobile web pages load faster by using a simplified form of HTML. Fast loading speeds can improve user experience and can contribute to better SEO performance, though AMP is not a direct ranking factor.


Google’s pay-per-click (PPC) advertising platform. (Please note, Google AdWords has been rebranded as Google Ads)


AhrefsBot is the web crawler for Ahrefs, a popular SEO tool suite. It crawls websites to collect information for Ahrefs’ backlink index. It’s not directly related to Google’s ranking, but understanding its function can be useful for SEO professionals using Ahrefs.

Alt Text

Alt text (alternative text) is used within an HTML code to describe the appearance and function of an image on a page. This helps improve website accessibility for visually impaired users using screen readers. Additionally, it provides context to search engines, helping them understand images, which can improve SEO performance.

Algorithmic Penalty

This is a penalty automatically applied by Google’s algorithms due to perceived violations of its guidelines.

Anchor Text

Anchor text is the clickable text in a hyperlink. SEO best practices dictate that anchor text should be relevant to the page you’re linking to. Anchor text can provide context about the content of the linked page to both users and search engines, influencing how search engines rank pages.

Article Spinning

Article spinning is a technique used to generate “new” content by rephrasing or reformatting existing content, often with the use of automated software. This practice is generally considered a black-hat SEO technique and can result in penalties from search engines due to the low quality and duplicative nature of the content produced.

Article Syndication

Article syndication is the process of distributing articles to other sites to reach a broader audience. If not handled correctly, article syndication can lead to issues with duplicate content. Therefore, it’s important to ensure syndicated content includes a link back to the original content.

Auto-Generated Content

Auto-generated content is content produced by automated means, often without human intervention. This could include content scraped from other websites, generated through AI or algorithms, or created using spinning software. Auto-generated content often lacks quality, relevancy, and value, and is generally seen unfavorably by search engines.

Above the Fold

Above the fold refers to the part of a webpage that is visible without scrolling when the page first loads. The term originates from the newspaper industry. In the context of web design and SEO, placing important content and call-to-actions above the fold can enhance user engagement and experience.


AJAX stands for Asynchronous JavaScript and XML. It is a set of web development techniques using many web technologies on the client-side to create asynchronous web applications. With AJAX, web applications can send and retrieve data from a server asynchronously without interfering with the display and behavior of the existing page.


In SEO, an algorithm often refers to the complex systems search engines use to retrieve and display the most relevant search results based on a user’s query. Google’s search algorithm considers many factors such as relevance, quality of content, and user experience signals.

Algorithm Change

Algorithm changes can be broken down into three subcategories:

  • Algorithm Update: This is when a search engine makes significant changes to its algorithms which can affect search results. Google’s Panda and Penguin are examples of such updates.
  • Algorithm Refresh: An algorithm refresh is when a search engine runs the same algorithm again. The algorithm itself doesn’t change, but the webpages it affects might since those pages may have changed.
  • New Algorithm: This refers to a search engine developing a completely new algorithm to improve search results. Google’s Hummingbird update introduced a new algorithm.

Alt Attribute

This refers to the attribute in HTML used to specify alternate text for an image that is used by screen readers for visually impaired users and by search engines to understand the image’s content.


In digital marketing, this refers to the collection and analysis of numerical data from a website. Analytics can reveal how a site is performing, where traffic is coming from, user behavior, and more, which can guide SEO strategy.

Author authority refers to a measure of how reputable or influential the author of a piece of content is in their field. While Google scrapped its official Author Rank, it still values expertise, authority, and trustworthiness.

Advanced Search Operators

Advanced search operators are special commands that you can input into search engines to refine your search. For SEO, they can be used to find specific information about a website, such as how many pages are indexed or to find specific files or pages.

An absolute link is a hyperlink that includes the complete URL, including the protocol (e.g., “http://” or “https://”) and the domain name. It specifies the exact web address to which the link points, enabling users and search engines to navigate directly to the target page.

Alt Tag

An alt tag, also known as an alt attribute or alt text, is an HTML attribute added to image tags. It provides alternative text that describes the content of an image, allowing search engines to understand and index images for relevant search queries. Alt tags are crucial for accessibility and SEO purposes.

Authority Site

An authority site is a website that is recognized as a trusted and credible source of information in a specific industry or niche. Authority sites typically have high-quality content, attract substantial organic traffic, and earn links from other reputable websites. Search engines consider authority sites to be reliable and often rank them higher in search results.


Also known as inbound links, backlinks are links from one website to a page on another website. They’re important for SEO because search engines like Google use backlinks as a signal of a page’s quality and relevance. A higher number of quality backlinks can improve a page’s rank in search results.

Bing Webmaster Tools

This is a free service as part of Microsoft’s Bing search engine that allows webmasters to add their websites to the Bing index crawler. The service also provides tools for webmasters to troubleshoot the crawling and indexing of their website, sitemap creation, submission and ping tools, website statistics, and more.

Behavioral Signals

These are user interaction signals that can potentially influence search engine rankings, such as click-through rates (CTR), bounce rates, and dwell time.

Bounce Rate

Bounce rate is a web analytics metric that represents the percentage of visitors who enter a site and then leave (“bounce”) rather than continuing to view other pages within the same site. A high bounce rate may indicate that the content is not relevant to visitors or that the website is difficult to use.

Branded Keywords

Branded keywords are search terms that include a brand’s name or variations of it. They indicate that searchers are already familiar with a company and are specifically seeking it out.

Breadcrumb Navigation

This is a type of site navigation that shows users their location on a website relative to the home page. Breadcrumb navigation is user-friendly and can also help search engines understand the structure and hierarchy of a website.

Bridge Page

Also known as a doorway page, a bridge page is a webpage created for the sole purpose of driving visitors to a different page. These pages often use excessive keyword targeting and can be seen as manipulative, potentially incurring penalties from search engines.

A broken link is a hyperlink that no longer points to its intended destination, often because the page it’s pointing to has been moved or deleted. Broken links can negatively impact user experience and can hinder a search engine’s ability to properly crawl and index a website.


Business-to-Business (B2B) refers to transactions or communications that occur between two businesses. In terms of SEO, a B2B approach can often involve more niche keywords and longer sales cycles.


Business-to-Consumer (B2C) refers to transactions or communications between a business and consumers. B2C SEO strategies typically aim to reach a wider audience and often focus on more general, high-volume keywords.


Baidu is the most popular search engine in China. Similar to Google, it offers a suite of web services like search, news, maps, cloud storage, and much more.

In SEO, black box often refers to the lack of transparency into how search engine algorithms work. While search engines provide general guidance on best practices, the exact factors and their weightings in ranking websites are not disclosed.


A blog is a regularly updated website or web page, typically run by an individual or small group, that is written in an informal or conversational style. Blogs can be a great way to regularly add fresh content to a website, which can help improve search engine rankings.


In the context of the internet, a bot (short for robot) is a software application that performs automated tasks. Search engine bots, like Googlebot or Bingbot, crawl and index web pages for inclusion in search results.

Backlink authority refers to the power or influence that a backlink from another website carries. It is determined by factors such as the linking website’s domain authority, relevance, and the quality of the backlink itself. Backlinks from authoritative and reputable websites are considered more valuable for improving a site’s search engine rankings.

A backlink profile represents the collection of all the backlinks pointing to a particular website. It includes information about the quantity, quality, and diversity of the backlinks. Analyzing the backlink profile helps understand a website’s link-building strategy and can guide efforts to improve SEO performance.

Bait and Switch

Bait and switch is an unethical tactic where a webpage presents misleading or false information to users or search engines. It involves luring visitors with one topic or offer and then redirecting them to a different, often unrelated, page. Bait and switch techniques violate search engine guidelines and can lead to penalties or loss of rankings.

Banner Blindness

Banner blindness refers to the phenomenon where website visitors consciously or unconsciously ignore or overlook banner advertisements. Due to frequent exposure to banner ads, users have developed a tendency to disregard them, which impacts the effectiveness of banner advertising as a marketing strategy.

Below The Fold

Below the fold refers to the portion of a web page that is not immediately visible to users when the page loads. It requires scrolling down to view the content. Historically, content placed below the fold received less attention, but with the rise of mobile devices and responsive design, the concept has become less significant.

Blended search, also known as universal search, refers to search engine result pages (SERPs) that include a mix of different content types, such as images, videos, news articles, maps, and more. Blended search aims to provide users with diverse and relevant results beyond traditional text-based listings.

Blog Commenting

Blog commenting involves leaving comments on blog posts to engage with the author and other readers. It can help build relationships, establish credibility, and drive traffic back to your own website if the comment includes a link. However, comments should be relevant, thoughtful, and add value to the conversation.

Blog Spam

Blog spam refers to unsolicited and irrelevant comments or links posted on blog posts solely for the purpose of self-promotion or manipulating search engine rankings. Blog spammers often use automated tools to generate large volumes of spammy comments, which can harm a website’s reputation and SEO efforts.

Brand mention link building involves acquiring backlinks by leveraging brand mentions across the web. It entails identifying instances where a brand or product is mentioned without a corresponding link and reaching out to the source to request a link. This strategy can help improve a website’s authority and visibility in search engines.

Brand Term

A brand term refers to a keyword or search query that includes a specific brand or company name. It can be the brand name itself or a variation of it. Optimizing for brand terms helps ensure that a website appears prominently in search results when users search for the brand or related terms.

Broad Match Keyword

Broad match keywords are search terms used in online advertising campaigns that trigger ads to appear for a wide range of related searches. They allow ads to be shown for variations, synonyms, and other relevant queries. Broad match keywords provide a broader reach but may result in lower targeting precision compared to more specific match types.

Browser Error Code

A browser error code indicates an issue or problem encountered when attempting to access a web page. Error codes, such as 404 (Page Not Found) or 503 (Service Unavailable), are displayed to users when a webpage cannot be retrieved. Monitoring and addressing browser error codes is important for user experience and SEO as they can negatively impact crawlability and indexing.


Cached Page

This is a version of a web page that Google stores and uses as a backup in case the original page is unavailable. Google presents a cache date which is the last time the page was crawled and stored.

Canonical Tag

Also known as “rel=canonical”, a canonical tag is an HTML element that helps prevent duplicate content issues by specifying the “preferred” version of a web page for search engines.


In SEO, co-citation refers to the process where one website or brand is mentioned (not linked) by two different sources. Co-citation can help search engines understand semantic connections between sites.


Co-occurrence in SEO refers to the frequency and proximity of similar keywords appearing on the same page. This can help search engines understand the relevancy and context of content.

Computer-Generated Content

This is content that’s created using software or algorithms. While it can create content quickly, computer-generated content often lacks quality and can be seen as spammy by search engines.

Content Delivery Network (CDN)

A CDN is a network of servers that are used to distribute the load of delivering content. By storing copies of web pages across a network of servers around the world, CDNs can help improve page load speed and accessibility, which are both important for SEO.

Content Hub

A content hub is a centralized digital space that stores and organizes content around a specific topic or category. By keeping related content together, a content hub can help improve site structure and internal linking, leading to better SEO.

Core Web Vitals

Introduced by Google, Core Web Vitals are a set of factors that are considered important in a webpage’s overall user experience. These include loading performance, interactivity, and visual stability of a page. They are part of Google’s page experience signals used for ranking websites.

Cornerstone Content

This is high-quality, foundational content that you want to rank highly for in search engine results. It’s content that accurately represents your business and the expertise you want to be known for.

Crawl Budget

This refers to the number of pages a search engine will crawl on your site within a certain timeframe. Google, for instance, does not want to overwhelm your server with crawling, so it spreads out its crawls over time.


Crawlability refers to a search engine’s ability to access and crawl content on a webpage. Factors impacting crawlability include the site’s URL structure, robots.txt file, site architecture, and more.


Also known as spiders, bots, or web crawlers, these are software programs that search engines use to scan the internet, visit websites, and index their content.

Core Web Vitals

Introduced by Google, Core Web Vitals are a set of factors that are considered important for a webpage’s overall user experience. Core Web Vitals are made up of three specific page speed and user interaction measurements: Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). Google uses these metrics in its ranking algorithm, emphasizing the importance of page experience.

  • Largest Contentful Paint (LCP): This measures the loading performance of a webpage. To provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading. LCP marks the point in the page load timeline when the page’s main content has likely loaded—a fast LCP helps reassure the user that the page is useful.
  • First Input Delay (FID): This measures the interactivity and responsiveness of a webpage. To provide a good user experience, pages should strive to have an FID of less than 100 milliseconds. FID quantifies the experience users feel when trying to interact with unresponsive pages—lower FIDs lead to a perception of a more responsive page.
  • Cumulative Layout Shift (CLS): This measures the visual stability of a webpage. To provide a good user experience, pages should strive to have a CLS score of less than 0.1. CLS looks at how much visible content shifts in the viewport, apart from user actions—low CLS helps ensure that the page is delightful to use.


Stands for country code Top-Level Domain. ccTLDs are internet domain extensions (like .us, .uk, .fr) that are assigned to specific countries. They signal to both users and search engines what the geographic target of a website is, and can influence search engine rankings in specific regions.

Click Bait

Clickbait refers to online content that is designed to attract attention and encourage visitors to click on a link to a particular web page. While it can drive traffic, it’s often associated with misleading or sensationalist content, which can harm reputation and user trust.

Click Depth

In SEO, click depth refers to the number of clicks required to reach a specific page from the home page of a website. Shallow websites, where pages are only 1 or 2 clicks from the home page, are seen as more user-friendly and are typically easier for search engines to crawl.

Click-Through Rate (CTR)

CTR is the percentage of users who click on a specific link to the total number of users who view a page, email, or advertisement. It’s an important metric in SEO as it indicates how compelling your webpage appears in search engine results.


This is a black hat SEO tactic where content presented to the search engine spider is different from that presented to the user’s browser. It’s deceptive and against search engine guidelines, as it can present users with content that’s irrelevant to what they were expecting to find.

CMS (Content Management System)

A CMS is a software that allows users to create, manage, and modify content on a website without needing specialized technical knowledge. Examples of CMS include WordPress, Joomla, and Drupal.

Code to Text Ratio

This is the percentage of a webpage’s total content that is made up of actual text as opposed to HTML code, CSS, JavaScript, etc. A higher code to text ratio can potentially improve a page’s chances of achieving better search engine rankings.


  • Direct Competitors: These are businesses that offer the same products or services as you, targeting the same audience in the same geographical area.
  • SEO Competitors: These are websites that are ranking high for the keywords that you want to rank for. They may not necessarily offer the same products or services as your business, but they compete for the same online visibility.

Conversion Rate Optimization (CRO)

CRO is a process of increasing the percentage of website visitors who complete a desired action by creating an optimal user experience on the website. This involves a range of strategies, including improving website design, streamlining navigation, and simplifying checkout processes.

Core Update

This term is used to describe changes made to Google’s main (core) ranking algorithm. Unlike smaller algorithm updates, a core update can significantly impact search results across all industries and countries.


In SEO, correlation refers to a measure of the relationship between two or more variables. SEOs often use correlation to understand the relationship between different factors and how they impact search engine rankings.

Crawl Error

This occurs when a search engine’s spider tries to crawl a particular page or site and fails. Crawl errors could be site-wide or restricted to individual URLs. They can harm SEO because they prevent search engines from properly indexing the affected pages.

CSS (Cascading Style Sheets)

CSS is a style sheet language used for describing the look and formatting of a document written in HTML. CSS is essential for the visual presentation of a website, and can also affect the site’s loading speed and accessibility, which can impact SEO.

Customer Journey

The customer journey is the process that a customer goes through when interacting with a company, from the initial discovery or awareness stage through to the point of purchase (conversion) and beyond. Understanding the customer journey is crucial for effective marketing and SEO, as it helps businesses to target their efforts at the right audience at the right time.

Call To Action

A call to action (CTA) is a prompt or directive given to website visitors to encourage them to take a specific action, such as making a purchase, signing up for a newsletter, or downloading a resource. CTAs are typically presented as buttons, links, or forms and play a vital role in guiding user behavior and achieving conversion goals.

Churn and Burn SEO

Churn and burn SEO, also known as black hat SEO, refers to aggressive and unethical practices aimed at quickly ranking websites but with a high risk of penalties or being banned from search engine results. These tactics prioritize short-term gains over long-term sustainability and often involve spammy techniques that violate search engine guidelines.

Code Swapping

Code swapping, in an SEO context, refers to the practice of frequently changing the code or content of a webpage to manipulate search engine rankings. This tactic is typically used to deceive search engines by presenting different content during the indexing process than what users actually see. Code swapping is a black hat technique and can result in penalties.

Competitor Analysis

Competitor analysis is the process of evaluating and studying the strategies, strengths, weaknesses, and online presence of competitors in a specific industry or niche. It involves analyzing their websites, keywords, backlink profiles, content strategies, and social media presence to gain insights and identify opportunities to improve your own SEO efforts.

Content Marketing

Content marketing involves creating and distributing valuable, relevant, and consistent content to attract and engage a target audience. It aims to provide useful information, solve problems, and build brand awareness and authority. Content marketing plays a crucial role in SEO by driving organic traffic, earning backlinks, and improving search engine rankings.

Content Silo Structure

Content siloing is an organizational structure for a website’s content that groups related topics or themes together. It involves creating a hierarchy of interconnected webpages to establish topical relevance and make it easier for search engines to understand the website’s structure and content relationships.

Cost Per Acquisition

Cost per acquisition (CPA) is a metric used in online advertising to measure the cost incurred to acquire a customer or lead. It calculates the total advertising spend divided by the number of acquired customers or leads. CPA is an important metric for evaluating the effectiveness and profitability of advertising campaigns.

Cost Per Action

Cost per action (CPA) is an online advertising pricing model where advertisers pay a fee each time a specific action is completed by a user, such as making a purchase, filling out a form, or subscribing to a service. CPA campaigns often require careful targeting and optimization to maximize conversions while minimizing costs.

Cost Per Thousand Impressions

Cost per thousand impressions (CPM) is an online advertising pricing model where advertisers pay a fixed amount for every one thousand ad impressions served. It is a common pricing method for display advertising, and advertisers are charged regardless of whether users interact with the ads or not.


Cross-linking, also known as interlinking, is the practice of linking between different pages or sections within the same website. It helps search engines understand the site’s structure and content relationships, improves user navigation, and distributes link equity throughout the website, potentially boosting SEO performance.

Curated Content

Curated content refers to the process of gathering, organizing, and presenting valuable and relevant content from various sources for a specific audience. Content curation involves selecting, filtering, and adding commentary to the curated content to provide additional value and context. Curated content can be beneficial for engaging users, building authority, and driving traffic.


This is a type of hyperlink that transfers SEO strength (link juice) from one site to another. These links can influence the rankings of the linked pages and are a strong signal to search engines about the page’s relevance.

Domain Rating (DR)

A metric developed by Ahrefs, DR predicts how well a website will rank on search engine result pages (SERPs). DR is measured on a scale from 0 to 100, with higher scores typically indicating more authoritative sites.

Doorway Page

This is a page created specifically to rank highly for particular search queries. They lead users to multiple similar pages in user or search engine results, and are considered to be a form of spam, which could lead to penalties from search engines.

Duplicate Content

This refers to substantial blocks of content within or across domains that either completely match other content or are appreciably similar. Duplicate content can negatively affect a site’s SEO as search engines may not know which version to index or rank for relevant search queries.

Dwell Time

Dwell time is the amount of time a user spends on your website after clicking on your site in search engine results and before returning back to the search results. Longer dwell times can be an indicator of high-quality, relevant content.

Dynamic URL

A URL that results from the search of a database-driven website or the URL of a website that runs a script. In contrast to static URLs, dynamic URLs are not always helpful for SEO as they tend to not be as clean or keyword-rich.


In the context of SEO, data can refer to any raw information gathered from various sources (like analytics tools, customer databases, etc.) that can be analyzed to gain insights and make informed decisions.

Dead-End Page

A web page without any outgoing links. These can harm the user experience and make it harder for search engines to crawl and index the site properly.

A deep link is a hyperlink that points to a specific page or image on a website, rather than that website’s home page. Deep links are useful for guiding users directly to relevant content, and can help to improve a site’s SEO.
