how search engine optimization work

Search Engine have one objective to provide you with the most relevant result possible in relation to your search query.

if the search engine is successful in providing you with information that meets your need, then you are a happy searcher. and happy searchers are more likely to come back to the same search engine time and time again because they are getting the results they need.

Q :- what is indexing in search engine?

In order for a search engine to be able to display result when a user types in a query, they need to have an archive of available information to choose from. Every search engine has proprietary methods for gathering and prioritizing website content. Regardless of the specific tactic or methods used, this process is called indexing.
search engine actually attempt to scan the entire online universe and index all the information so they can show t to you when you enter a search query.

Q :- how do search engine do it ?

every search engine has what are referred to as bots or crawlers, that constantly scan the web, indexing websites for content and following links on each webpage to other webpages. if your website has not been indexed, it is impossible for your website to appear in the search result. Unless the Search Engine Results Page (SERP), chances are your website has already been indexed

So, big search engine like Google, Bing, and Yahoo are constantly indexing hundreds of millions, if not billions, of webpages. how do they know
what to show on the SERP when you enter a search query ?
The search engines consider two main areas when determining what your website is about and how to prioritize it.

1) Content on your website :

 when indexing pages, the search engine bots scan each page of your website, looking for clues about what topics your website covers and scanning your website's back-end code for certain tages, descriptions and instructions. that HTML tags are meta tag in this keyword and content of your webpage.

2) Who's linking to you :

 As the search engine bots scan webpages for indexing, they also look links from other websites. The more inbound links a website has, the more influence or authority it has. Essentially, every inbound link counts as a vote for that website's content. Also, each inbound link holds different weight, for instance, a link from a highly authoritative website like The New York Times (nytimes.com) will give a website a bigger boost then a link from a small blog site. this boost is sometimes referred to as link juice

When the search query is entered, the search engine looks in its index for the most relevant information and displays and the result on the SERP (Search Engine Result Page). The result are then listed in order of most of most relevant and authoritative.
if you conduct the same search on different search engines chances are you will see different results on the SERP. this is because each search engine uses a see different algorithm that considers multiple factors in order to determine what results to show in the SERP when a search query is entered.

 

                           

A few factors that a search engine algorithm may consider when deciding what information to show in the SERP include:

• Geographic location of the searcher
• Historical performance of a listing (clicks, bounce rates, etc.)
• link quality (reciprocal vs. one-way)
• back end code or HTML of webpage
• link type (social media sharing, link from media outlet, blog, etc.)
