How SEO Works

How does a search engine work? Search engines are used when people ask questions and search for answers on the Internet.

Crawl, discovery stage—indexing, which is the filing phase. The ranking is the search phase.

Step 1: Crawl

The first step is to crawl. Search engines send web crawlers to find new pages and record information about them. These web crawlers are sometimes referred to as “spiders” or “robots.” Their purpose is to discover new web pages and regularly check the content of previously visited pages to see if they have changed or updated. The search engine crawls your website by following the links you have already found. Therefore, if you have a blog post linked from the home page, when a search engine crawls the home page, it may look for another link and follow the link to the new blog post.

Step 2: Indexing

The second step is indexing. During indexing, search engines decide whether to use crawled content. When a crawled web page is considered valuable by a search engine, it is added to its index. This index will be used in the final ranking phase. Once a web page or part of the content is indexed, it is filed and stored in the database for later retrieval.

Step 3: Ranking

The last step is the most crucial step, which is ranking. Ranking can only be done after the crawl and indexing steps are complete. Therefore, when a search engine crawls your site and indexes it, you can rank your site.
There are over 200 ranking signals occur that search engines use to sort and rank content, all of which apply to the three pillars of SEO: technical optimization, on-page optimization, and off-page optimization.
