2. How Search Engines Work
Understanding how search engines work is fundamental to effective SEO. Search engines like Google use a three-step process:
Crawling
Search engines use automated programs called "crawlers" or "spiders" to discover and visit web pages across the internet. They follow links from page to page, building a massive database of web content.
Indexing
After crawling, search engines analyze and store the information from each page in their index �a massive database. They understand the content, context, and relationships between pages.
Ranking
When a user searches, the search engine retrieves relevant pages from its index and ranks them based on hundreds of factors to provide the most useful results.
Important Note
Search engines constantly update their algorithms. Google makes thousands of algorithm changes each year to improve search results quality.
