SEO Glossary: Terms & Definitions

Establishing a strong online presence is no longer optional for businesses aiming for growth — it’s essential. Central to this online visibility is Search Engine Optimization (SEO). 

However, the field of SEO is filled with specific terminology that can often seem like a complex code. For marketing directors and business owners, understanding this language is the first step toward harnessing the power of SEO to drive traffic, generate leads, and ultimately increase return on investment (ROI). 

To help you understand your place in the system and all we can do for you, Dallas SEO Dogs presents our foundational SEO Glossary, designed to demystify the jargon and provide clarity on essential concepts. Familiarity with these terms empowers businesses to engage more effectively in SEO strategies, whether implemented in-house or through a partner agency.

What Does SEO Stand For?

Let’s start with the basics. Many people ask, What does SEO stand for? SEO stands for Search Engine Optimization. At its core, SEO is the practice of optimizing a website and its content to improve its visibility in search engine results pages (SERPs) for relevant user queries. 

The goal is to attract more organic (non-paid) traffic from search engines like Google, Bing, and others. When someone searches for products, services, or information related to a business, effective SEO helps that business appear higher in the search results, making it more likely that the user will click through to their website. 

Understanding what SEO stands for is the first step — appreciating its impact is next. SEO involves a wide range of techniques, from technical website adjustments to content creation and link building, all aimed at signaling relevance and authority to search engines. 

Understanding SEO Terms

Navigating the world of digital marketing requires a certain level of literacy in its specialized language. Understanding SEO terms is crucial for several reasons. Firstly, it allows business leaders and marketing directors to have informed conversations about strategy and performance. When discussing campaigns, audits, or results it makes it a lot easier to communicate and set goals when you know the difference between indexing and ranking, or on-page versus off-page SEO!

Secondly, familiarity with SEO terms enables better evaluation of SEO efforts and reports. Metrics like Click-Through Rate (CTR), Bounce Rate, and Conversion Rate are fundamental indicators of performance. Understanding these helps businesses gauge the effectiveness of their SEO investment and its contribution to the bottom line. Without this understanding, SEO can feel like a black box.

Finally, a grasp of key SEO terms empowers businesses to make more strategic decisions. Understanding keyword research, user intent and E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) helps align your SEO activities with broader business objectives. 

This is foundational knowledge that transforms SEO from a mysterious technical task into a tangible business driver. This Glossary of terms can provide that foundation.

SEO From A to Z | Your Comprehensive SEO Glossary

To help businesses navigate the complexities of search engine optimization, here is a comprehensive SEO Glossary covering essential terminology. This resource, effectively a detailed Glossary of SEO, is designed to be a quick reference guide. Understanding this SEO Glossary of terms is vital for anyone involved in digital marketing or overseeing a business’s online presence. We present this SEO Glossary of terms alphabetically for ease of use.

Algorithm

A complex set of rules and calculations used by search engines (like Google) to determine the relevance and ranking of web pages for specific search queries. Search engine algorithms are updated frequently.

Alt Text (Alternative Text)

A description added to an image’s HTML tag. Alt text helps search engines understand the content of an image and improves accessibility for visually impaired users relying on screen readers.

Analytics

The collection, measurement, analysis, and reporting of web data, typically used to understand user behavior and website performance. Google Analytics is a widely used tool.

Anchor Text

The visible, clickable text in a hyperlink. Using descriptive, relevant anchor text can help search engines understand the context of the linked page and can influence rankings.

Backlinks (Inbound Links)

Links from external websites pointing to your website. Backlinks are a crucial ranking factor, as they signal to search engines that other sites trust your content. Quality and relevance matter more than quantity.

Black Hat SEO

SEO practices that violate search engine guidelines in an attempt to manipulate rankings. These tactics (like keyword stuffing or buying links) can lead to penalties, including removal from search results.

Bounce Rate

The percentage of visitors who navigate away from a website after viewing only one page. A high bounce rate can indicate your page content isn’t meeting user expectations or providing a good user experience.

Breadcrumbs

Navigational links typically found near the top of a webpage, showing the user’s location within the site’s hierarchy (e.g., Home > Services > SEO). These improve user experience and help search engines understand site structure.

Cache

A temporary storage area where website files (like images and HTML) are saved by a browser or server. Caching helps websites load faster for repeat visitors.

Canonical Tag (rel=”canonical”)

An HTML tag used to specify the preferred version of a web page when multiple URLs display similar or duplicate content. It helps consolidate link equity and prevent duplicate content issues.

Citations

Citation sites are online directories. These sites, like Yelp, Google, or Bing, help improve local SEO by validating the business information across the web.  The sites will publish the business name, address, phone number (NAP), and website. 

Click-Through Rate (CTR)

The percentage of users who click on a specific link (e.g., a search result or an ad) out of the total number of users who viewed it (impressions). CTR is a key metric for evaluating SERP performance and ad effectiveness.

Content Marketing

Creating and distributing valuable, relevant, and consistent content (like blog posts, articles, videos) to attract and retain a clearly defined audience, ultimately driving profitable customer action. Crucial for SEO.

Conversion Rate

The percentage of website visitors who complete a desired action (a conversion), such as making a purchase, filling out a form, or signing up for a newsletter.

Crawling

The process by which search engine bots (spiders or crawlers) discover new and updated content on the web by following links.

CSS (Cascading Style Sheets)

A stylesheet language used to describe the presentation (look and formatting) of a document written in HTML. CSS separates content from design.

Domain Authority (DA)

A score developed by Moz that predicts how well a website will rank on search engine result pages. DA is based on factors like linking root domains and the number of total links. While not used by Google, it’s a common comparative metric.

Duplicate Content

Content that appears on the internet in more than one location (URL). Significant duplicate content can dilute rankings and confuse search engines; canonical tags help manage this.

E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness)

A concept from Google’s Search Quality Rater Guidelines was used to assess web page quality, especially for “Your Money or Your Life” (YMYL) topics. Demonstrating E-E-A-T is crucial for ranking well.

External Links (Outbound Links)

Links from your website point to other websites. Linking to relevant, authoritative external sources can enhance the credibility and usefulness of your content.

Featured Snippets

Selected search results featured in a box at the top of Google’s organic results, designed to directly answer a user’s query. Earning a featured snippet provides significant visibility.

Google Analytics

A free web analytics service offered by Google that tracks and reports website traffic, user behavior, conversions, and more. Essential for measuring SEO success.

Google Search Console (GSC)

A free service from Google that helps website owners monitor, maintain, and troubleshoot their site’s presence in Google Search results. It provides data about crawling, indexing, security issues, and search performance.

SEO practices that are technically not against search engine guidelines but are ethically questionable and potentially risky. They fall between White Hat and Black Hat SEO.

Headings or Heading Tags (H1, H2, H3, etc.)

HTML tags used to structure content on a webpage, creating a hierarchy. H1 is typically the main title, followed by H2 for major sections, H3 for subsections, etc. Headings help users and search engines understand content structure.

HTML (HyperText Markup Language)

The standard markup language used to create web pages and web applications. Defines the structure and content of a page.

Indexing

The process by which search engines store and organize the information gathered during crawling. Once a page is indexed, it becomes eligible to appear in search results.

Internal Links

IP Address (Internet Protocol Address)

A unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.

Keyword Density

The percentage of times a specific keyword appears on a web page relative to the total word count. Once considered important, modern SEO focuses more on natural language use and topic relevance than strict keyword density.

Keyword Research

The process of identifying popular words and phrases (keywords) that users enter into search engines when looking for information, products, or services related to your business. Foundational to any SEO strategy.

Keywords

Keywords are the words and phrases that users type into search engines. Primary keywords are the main search term, followed by the secondary keywords that support the primary. Optimizing content for relevant keywords helps search engines match your pages to user queries.

Google primarily uses the mobile version of content for indexing and ranking. This makes having a mobile-friendly website critical for SEO performance.

Nofollow Attribute (rel=”nofollow”)

An HTML attribute added to a link to instruct search engines not to pass link equity (PageRank) to the linked page. Often used for paid links, user-generated content, or untrusted sources.

Off-Page SEO

Optimization activities performed outside of your own website to impact your rankings within SERPs. Primarily involves link building and building brand signals.

On-Page SEO

Optimization techniques applied directly within your website’s pages to improve rankings and user experience. Includes optimizing content, title tags, meta descriptions, headings, images, and internal links.

Organic Search Results

The unpaid listings on a SERP that the search engine deems most relevant to the user’s query based on its algorithms. SEO focuses on improving visibility in these results.

PageRank

An algorithm historically used by Google to rank web pages in their search results. It works by counting the number and quality of links to a page to estimate its importance. While still part of the core algorithm, it’s just one of many ranking factors now.

Page Speed

How quickly content loads on a webpage. Page speed is a ranking factor (especially on mobile) and significantly impacts user experience. Tools like Google PageSpeed Insights measure this.

PPC (Pay-Per-Click)

An internet advertising model where advertisers pay a fee each time one of their ads is clicked. Search engine advertising (like Google Ads) is a common form of PPC. Often works synergistically with SEO.

Query

Methods for sending users and search engines to a different URL from the one they originally requested. A 301 redirect indicates a permanent move (passing most link equity), while a 302 indicates a temporary move.

Robots.txt

A text file located in a website’s root directory that instructs search engine crawlers which pages or sections of the site should not be crawled or indexed.

ROI (Return on Investment)

A performance measure used to evaluate the efficiency or profitability of an investment. In SEO, ROI calculates the revenue generated from organic search traffic relative to the cost of the SEO efforts. Understanding SEO terms helps in accurately measuring ROI.

Schema Markup (Structured Data)

Technical SEO

Optimizing the technical aspects of a website to help search engines crawl and index it more effectively. Includes site speed optimization, mobile-friendliness, site architecture, structured data, and managing crawl errors.

Title Tag

An HTML element specifying the title of a web page. Title tags are displayed on SERPs as the clickable headline for a given result and are a critical factor for on-page SEO and user engagement.
