how search engine works step by step

In the first place, web indexes slither the Web to see what is there. This assignment is performed by a bit of programming, called a crawler or a creepy crawly (or Googlebot, similar to the case with Google). Bugs take after connections starting with one page then onto the next and list all that they find on their way. Having as a top priority the quantity of pages on the Web (more than 20 billion), it is unthinkable for a creepy crawly to visit a webpage day by day just to check whether another page has showed up or if a current page has been changed, once in a while crawlers may not wind up going by your website for a month or two.

What you can do is to check what a crawler sees from your site. As of now specified, crawlers are not people and they don’t see pictures, Flash films, JavaScript, outlines, watchword ensured pages and registries, so on the off chance that you have huge amounts of these on your site, you would do well to run the Spider Simulator underneath to check whether these treats are perceptible by the insect. On the off chance that they are not visible, they won’t be spidered, not recorded, not handled, and so on – in a word they will be non-existent for web indexes.
