Hey guys! As promised, here is a post about search engine spiders and how they index your website. This is a very complex but important part of search engines. Without these spiders, search engines would not be able to work like you know them today.
Search engine spiders, also called robots or crawlers are used by search engines to index all the websites on the internet. They basically go through your website and check all the texts, images, hyperlinks, meta tags, etc… This allows the search engine to know what each website talks about and then display it wisely in the search results when you search for something. If you can not find what your are searching for, it is all their fault!
They create a sort of profile for your website from all the collected information. There are some exceptional cases though… Have you ever seen an empty webpage displayed in the first page of search results? Well this is due to the fact that you can use the robot meta tag to block these spiders from indexing your entire website or just a part of your website. You just need to put what pages of your website you don’t want to be indexed in the content of your robot meta tag. This is why these spiders are useful for search engines but to a certain extent. The good news is that there are also people who are working on this. This is why it is very rare to find an empty website in the first results.
These search engine spiders check all the websites regularly to see if there has been any change so that they can update the website’s “profile” and its place in search results. Generally, the more you are active on a website the better it is graded in SEO. This is why blogs are very much recommended for SEO. If you feel like your website has not been indexed, you can send your website to a search engine to be checked. This will be the object of a future post.
Finally search engine robots can also be used to control websites. If the content is not okay or legal, your website can be taken off the web. This is a way of assuring the users that the content displayed is always checked.
