How Search Engines Work
Crawling
Search engines use bots (crawlers or spiders) to discover and scan web pages. They follow links from page to page, building a map of the web.
Crawl Budget: The number of pages a search engine will crawl on your site within a given timeframe.
Indexing
After crawling, search engines store and organize the information from pages in their index - a massive database of web pages.
Index Coverage: The percentage of your website's pages that are included in the search engine's index.
Ranking
When someone searches, the search engine retrieves relevant pages from its index and ranks them based on hundreds of ranking factors.
Algorithms: Complex mathematical formulas that determine which pages appear first in search results.
Serving Results
The search engine displays the most relevant and highest-ranking pages in the search engine results pages (SERPs).
SERP Features: Rich snippets, knowledge panels, local packs, and other enhanced search results.
