A search engine is a giant librarian for the internet.
Search engines (like Google and Bing) crawl websites, store what they find in an index, and then rank pages when you search.
If your site isn’t in the index, it can’t show up. If it’s in the index but weak, it shows up on page 7… where websites go to die.
How search engines work (simplified) 🔍
- Crawl: bots discover pages by following links
- Index: they store what the page is about
- Rank: they decide which pages are best for a query
That’s why SEO exists: it helps search engines understand your pages and helps your pages deserve to rank.
What search engines care about ✅
- Helpful site content (answers the question)
- Clear structure (headings, internal links, readable layout)
- Trust signals (links from other sites)
- No weird indexing issues (like duplicate content)
Search engines FAQ 🙋
What is a search engine?
A search engine is a system that crawls websites, indexes pages, and ranks them when users search for something.
What’s the difference between crawling and indexing?
Crawling is discovering pages. Indexing is storing and understanding what those pages are about.
How do I get my website into Google?
Make sure your site is accessible, has useful content, and is linked internally. Then submit your sitemap in Search Console and build pages worth indexing.
Is Google the only search engine?
No. Google is the biggest, but there are others like Bing and privacy-focused engines. Many still use the same basic principles.
Do search engines rank websites or pages?
Mostly pages. A strong website helps, but each page must be relevant and helpful to rank for a specific search.
