SEO Terminology
Comprehensive SEO Glossary
Understanding SEO terminology is essential for anyone looking to improve their online presence. This comprehensive glossary covers key SEO terms with special emphasis on Conversion Rate Optimization (CRO) - the critical process of turning website visitors into customers. Whether you're new to SEO or looking to deepen your knowledge, this guide will help you navigate the complex world of search engine optimization.
Conversion Rate Optimization is particularly important because it represents the intersection of SEO and business results. While SEO drives traffic to your website, CRO ensures that traffic converts into valuable actions like purchases, sign-ups, or inquiries. Together, they form a powerful strategy for digital marketing success.
Key Terms
Essential SEO Terminology
A
Algorithm
A set of rules used by search engines to rank web pages in their search results. Google's algorithm considers hundreds of factors to determine which pages appear for specific queries.
Anchor Text
The clickable text in a hyperlink. SEO best practices recommend using descriptive anchor text that gives users and search engines context about the linked page's content.
Alt Text (Alternative Text)
Descriptive text added to an image's HTML tag that helps search engines understand the image content. Alt text improves accessibility and can appear in image search results.
B
Backlink
A link from one website to another. Quality backlinks from authoritative sites are a significant ranking factor, as they serve as "votes of confidence" for your content.
Bounce Rate
The percentage of visitors who leave your website after viewing only one page. A high bounce rate may indicate irrelevant content or poor user experience, which negatively impacts Conversion Rate Optimization.
C
Conversion Rate
The percentage of website visitors who complete a desired action (conversion). This is a central metric in Conversion Rate Optimization and measures the effectiveness of your website at turning visitors into customers or leads.
Conversion Rate Optimization (CRO)
The systematic process of increasing the percentage of website visitors who complete desired actions. Conversion Rate Optimization involves testing and improving various elements of a website to maximize conversions. It works hand-in-hand with SEO to ensure that the traffic you attract actually converts into business results.
Call to Action (CTA)
A prompt designed to encourage immediate response from website visitors. Effective CTAs are crucial for Conversion Rate Optimization as they guide users toward conversion points.
Content Marketing
The strategic creation and distribution of valuable content to attract and engage a target audience. Quality content supports both SEO efforts and Conversion Rate Optimization by providing value to visitors and encouraging conversions.
Click-Through Rate (CTR)
The percentage of people who click on a search result after seeing it. A higher CTR indicates that your title tags and meta descriptions are compelling to users.
D
Domain Authority
A search engine ranking score developed by Moz that predicts how well a website will rank on search engine result pages. Scores range from 1 to 100, with higher scores indicating greater ranking potential.
E
Evergreen Content
Content that remains relevant and valuable to readers over time, regardless of current trends or news cycles. Evergreen content typically maintains its search rankings and traffic for extended periods.
F
Featured Snippet
A highlighted search result that appears at the top of Google's search results page, providing a quick answer to a user's query. Also known as "position zero."
H
Heading Tags
HTML elements (H1, H2, H3, etc.) used to structure content on a webpage. Proper use of heading tags helps search engines understand the content hierarchy and improves readability.
K
Keyword
A word or phrase that users enter into search engines to find relevant content. Keyword research is fundamental to SEO strategy and should align with Conversion Rate Optimization goals by targeting terms with commercial intent.
Keyword Difficulty
A metric that estimates how hard it would be to rank for a particular keyword based on competition and authority of existing ranking pages.
Keyword Intent
The underlying purpose behind a search query. Understanding keyword intent is crucial for both SEO and Conversion Rate Optimization, as it helps create content that matches what users are looking for.
L

A standalone web page created specifically for a marketing or advertising campaign. Landing page optimization is a critical component of Conversion Rate Optimization, as these pages are designed to drive conversions.
Local SEO
The practice of optimizing a website to rank better in local search results. Local SEO is particularly important for businesses with physical locations serving specific geographic areas.
M
Meta Description
An HTML attribute that provides a brief summary of a web page. While not a direct ranking factor, compelling meta descriptions can improve click-through rates from search results.
Mobile-First Indexing
Google's practice of primarily using the mobile version of a site's content for indexing and ranking. With most searches now happening on mobile devices, mobile optimization is essential for both SEO and Conversion Rate Optimization.

On-Page SEO
The practice of optimizing individual web pages to rank higher and earn more relevant traffic. On-page SEO includes optimizing content, HTML source code, and images.
Off-Page SEO
Actions taken outside of your own website to impact your rankings within search engine results pages. This primarily involves building quality backlinks and establishing authority.
P
Page Experience
A set of signals that measure how users perceive the experience of interacting with a web page. Google's page experience signals include loading performance, interactivity, and visual stability.
Page Speed
The time it takes for a web page to load completely. Page speed is both a ranking factor and a critical element of Conversion Rate Optimization, as faster pages tend to have lower bounce rates and higher conversion rates.
Q
Quality Score
A metric used in Google Ads that measures the relevance and quality of your keywords, ads, and landing pages. While primarily for paid search, the principles behind Quality Score also apply to organic search and Conversion Rate Optimization.
R
Responsive Design
An approach to web design that makes web pages render well on a variety of devices and window sizes. Responsive design is essential for both SEO (as it's a ranking factor) and Conversion Rate Optimization (as it improves user experience across devices).
S
Search Intent

T
Technical SEO

An HTML element that specifies the title of a web page. Title tags are displayed on search engine results pages as the clickable headline for a given result and are an important ranking factor.
U
User Experience (UX)

W

Deep Dive
Conversion Rate Optimization: The SEO Connection
Why CRO Matters for SEO
Conversion Rate Optimization is not separate from SEO—it's the natural extension that turns SEO efforts into business results. While SEO drives qualified traffic to your website, CRO ensures that traffic converts into valuable actions like purchases, sign-ups, or inquiries.
Search engines increasingly prioritize user experience signals, many of which overlap with CRO principles. Pages that convert well typically have:
- Lower bounce rates
- Longer time on site
- Higher engagement metrics
- Better mobile experience
These positive user signals can indirectly influence search rankings, creating a virtuous cycle where better conversions lead to better SEO performance.
Key CRO Strategies That Impact SEO
Several Conversion Rate Optimization techniques directly support SEO efforts:
1. Improving Page Speed
Faster loading pages not only rank better but also convert better. Even a one-second delay can reduce conversions by 7%.
2. Mobile Optimization
With mobile-first indexing, providing an excellent mobile experience is essential for both rankings and conversions.
3. Quality Content Creation
Content that addresses user intent thoroughly satisfies both search algorithms and human visitors, leading to better rankings and higher conversion rates.
4. Clear Call-to-Actions
Well-designed CTAs guide users through the conversion funnel while providing clear signals about page purpose to search engines.

Conversion Rate
The percentage of visitors who complete desired actions

Percentage of single-page sessions without interaction
