What this is: quick definitions of the SEO terms I keep running into while building and fixing my websites.
How to use it: when you see a term you don’t recognize, search this page and get the meaning in 15 seconds.
Quick note: I’m keeping these definitions simple on purpose. I’m not trying to sound smart — I’m trying to get results.
Jump to a term
Title Tag
Definition: The main headline search engines can show for a page. It’s usually the clickable blue link in search results.
Why it matters: It affects clicks and helps engines understand what the page is about.
Example: SEO Glossary for Beginners (10 Terms You’ll Actually Use)
Meta Description
Definition: The short summary text that can appear under the title in search results.
Why it matters: It can increase clicks by telling people exactly what they’ll get.
Example: Simple definitions of SEO terms like title tags, indexing, noindex, schema, and redirects.
URL Slug
Definition: The readable part of the URL after your domain.
Why it matters: Clean slugs help clarity and avoid ugly, confusing URLs.
Example: /seo-glossary-for-beginners/
Internal Links
Definition: Links from one page on your site to another page on your site.
Why it matters: They help search engines discover pages and help readers find the next step.
- Good internal link: from a “Yoast settings” post → to a “Title tags” section.
- Bad internal link: random links that don’t help the reader.
Sitemap
Definition: A file that lists your site’s pages so search engines can discover them faster.
Why it matters: It helps new or updated pages get found, especially on smaller sites.
What I check: that the sitemap exists and that important pages are included.
Indexing
Definition: When a search engine stores your page in its system so it can show the page in results.
Why it matters: If a page isn’t indexed, it usually won’t show up in search results.
What I do: use Google Search Console URL inspection to see if it’s indexed.
Noindex
Definition: A setting that tells search engines: “Do not show this page in search results.”
Why it matters: Accidentally setting noindex can kill a page’s search visibility.
Common mistake: a plugin or theme marks tag pages, category pages, or even important pages as noindex by accident.
Canonical URL
Definition: The “main” version of a page when multiple URLs are similar or duplicates.
Why it matters: It helps prevent duplicate-content confusion.
Example: If two URLs show the same content, set one as the canonical “official” page.
Schema Markup
Definition: Extra structured information that helps search engines understand what a page is (article, person, organization, FAQ, etc.).
Why it matters: It strengthens “meaning signals” and can improve how your page is understood.
My rule: only use FAQ when the questions and answers are real and visible on the page.
301 Redirect
Definition: A permanent redirect from one URL to another.
Why it matters: It saves your traffic and links when you change URLs or fix 404 pages.
Example: Old broken URL → redirects to the correct page instead of showing a 404 error.
