How search engines work?
Search engines are the backbone of the internet, providing users with a way to find the information they need. But how do they actually work? In short, search engines use complex algorithms to scour the web for websites, rank them based on relevance, and then present them to users in a search results page. But there’s a lot more that goes into it than that. Let’s take a closer look at how search engines work, and how they continue to evolve.
First, it’s important to understand that the web is constantly changing. New websites are being created and old ones are being updated all the time. This means that search engines have to continuously crawl the web in order to keep their index up-to-date. When you perform a search, the search engine will check its index to see if any relevant results exist. If there are no relevant results, the search engine will return an error message.
The second thing to understand is that not all websites are created equal. Some websites are well-designed and frequently updated, while others are neglected and out-of-date. Search engines use a variety of factors to determine which websites should be ranked higher in the search results.
Understanding how search engines read a web page can help webmasters and SEOs improve their website’s crawlability and indexation.
Search engines use algorithms to crawl and index websites. These algorithms are constantly changing, which means that what works today may not work tomorrow. However, there are some general principles that remain constant.

What is crawling?
Crawling is the process by which search engines discover new and updated content. They do this by following links from other websites, as well as through sitemaps submitted by webmasters.
What is indexing?
Indexing is the process of adding new content to a search engine’s index. This index is used to determine what results should be shown for a given query.
What is caching?
Caching is the process of storing a copy of a web page in a search engine’s cache. This cached version can be served to users instead of the live version, which can help improve performance.
Webmasters and SEOs can improve their website’s crawlability by ensuring that their pages are well-linked and by submitting sitemaps in Google search console. They can also improve their website’s indexation by using relevant keywords and tags, and by providing quality content.
