SEO Terms Glossary: 50 Must-Know Terms for Beginners
Ever felt like SEO pros are speaking a different language? You’re not alone. When I first started, terms like “canonical tags” and “latent semantic indexing” made my head spin.
But here’s the truth: SEO isn’t rocket science—it’s just a set of tools. And if you want to rank higher, get more traffic, and crush your competition, you need to speak the language.
So let’s break it down. No fluff. No jargon. Just 50 essential SEO terms every beginner should know.
🔍 Basic SEO Terms You Need to Know
1. SEO (Search Engine Optimization)
The process of optimizing your website to rank higher on search engines like Google. More visibility = more traffic.
2. SERP (Search Engine Results Page)
The page you see after typing a query into Google. Ranking on the first page = gold.
3. Keyword
The word or phrase people type into search engines. Example: “best running shoes”.
4. Long-Tail Keyword
A longer, more specific keyword phrase (usually 3+ words). Less competition, better conversion. Example: “best running shoes for flat feet”.
5. On-Page SEO
Optimizing elements on your website (titles, content, images) for better rankings.
6. Off-Page SEO
Actions taken outside your website (backlinks, social signals) to boost rankings.
7. Backlink
When another website links to yours. High-quality backlinks = trust in Google’s eyes.
8. Domain Authority (DA)
A score (0-100) predicting how well your site will rank. Higher DA = stronger site.
9. Page Authority (PA)
Same as DA, but for individual pages instead of the whole site.
10. Meta Title
The clickable headline in search results. Keep it under 60 characters.
11. Meta Description
The short blurb under your title in SERPs. Aim for 150-160 characters.

18. Bounce Rate
The percentage of visitors who leave your site without taking any action. High bounce rate? Fix your content.
19. CTR (Click-Through Rate)
The % of people who click your link after seeing it in search results. Higher CTR = better rankings.
20. Latent Semantic Indexing (LSI Keywords)
Related terms Google uses to understand context. Example: For “Apple,” LSI keywords could be “iPhone” or “MacBook.”
21. Featured Snippet
The highlighted answer box at the top of Google. Also called “Position 0.”
22. Schema Markup
Code that helps search engines understand your content better. Can boost rich snippets.
