A SERP is a Search Engine Results Page — the page of results a search engine shows after a query. It includes organic listings, paid ads, and features like featured snippets and AI overviews.

What does SEO stand for?

SEO stands for Search Engine Optimization — the practice of improving a website so it ranks higher in search results and attracts more relevant organic traffic.

What is the difference between crawling and indexing?

Crawling is how search engines discover pages by following links. Indexing is storing a crawled page so it can appear in results. A page must be both crawled and indexed before it can rank.

A backlink is a link from another website to yours. Search engines treat relevant, high-quality backlinks as votes of confidence, making them one of the strongest signals of authority and a major ranking factor.

What does E-E-A-T mean in SEO?

E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trust. It describes the qualities Google's guidelines look for in credible content, and it matters most for topics that affect people's health, finances, or safety.
