One of the most common questions people ask is how search engines create the index. Well, the index includes the discovered URLs based on a few key signals. First of all, it analyses the keywords on the page content. The most relevant keyword stuffing receives a higher ranking. 

The type of content is another important parameter, and then the search engine analyzes the freshness of the data. Most recently updated pages are rated on a priority basis. The previous user engagements on the specific pages are also evaluated. If certain pages engage more audiences on a routine basis, they will naturally receive a higher ranking on search engine results as well. 

What Happens When Users Perform A Search Online?

The main aim of the search engine algorithm is to bring the most relevant data to the searchers to answer their queries. Then users can select any desired page from the list to learn more details.

Whenever any query is added to the search engine, the algorithm looks for the pages in the index. When it finds the most relevant content code, the results are presented back on the user screen. Usually, the search results are influenced by four major parameters; they are a device, previous search history, language detected and location.

For instance, when you enter a query asking restaurants around me, it will display results based on your nearby area. Users can also select the specific language to initiate a search in the desired form.

Some search results are also dependent on previous search history. In a few cases, they may be returned depending upon the type of device you use to initiate queries. 

The main goal of the Google search engine is to deliver the most relevant and most useful content to the user. And in order to achieve this target, it keeps on updating its search engine algorithm from time to time.
