How does search engine work?

 Search Engines are designed programs to search information on the web. When you type any word in search engine that is called keyword or query, at that time search engine finds the information related to that keyword and displays on the web. There is an algorithm behind this program to search on the web.

When you type the keyword then engine start gathering the information according to that query and this algorithm is going changing after some days.

In case of Google, when the algorithm gets changed then people says that Goggle Panda gets changed. The idea behind this, Google has one engineer “Navneet Panda” from India, who had made the first algorithm for Google that’s why people often says Panda gets updated.

The idea behind updating the algorithm is for spamming, black hat SEO, un legal practices of SEO, etc. If people got the idea about that formula then there is no use of this program. Anyone can make their website according to that formula and Goggle wont this. Because Goggle wants to give quality results to their researchers and for that they keep changing their algorithm.

After entering query in search engine Goggle shows indexed pages or it searches for updates. When you submit your site to Google, it indexed your page and saves a copy of that page on the server. When query enters Goggle goes to indexed page of your website. It searches the updates on your page and if the page doesn’t have any updates then it goes for another page.
