Search engine marketing is an essential part of your online existence. It may not be the only source of traffic you can get, but with billions of searches every year, it is a force not to ignore. Every single person that is active “searching” for something will use a search engine to find it. Thus it’s far better to understand how these search engines really work and how they present information to the shopper. There are largely 2 sorts of search engines.
The first is by robots called crawlers or spiders.
Search Engines use spiders to index sites. When you submit your web pages to a search engine by completing their needed submission page, the search engine spider will index your complete site. A ‘spider’ is an automated program that is run by the search engines. Spider visits a web page, read the content on the page, the page’s meta tags and also follow the URLs that the page links to.
The spider then returns all that data back to a central repository, where the data is indexed. It’ll visit each link you have on your page and index those pages as well. Some spiders will only index a certain number of pages on your website, so don’t make a site with 5 hundred pages! The spider will intermittently return to the sites to test for any info which has modified. The frequency with which this occurs is set by the judges of the search engine.
A spider is similar to a book where it contains the table of contents, the particular content and the links and references for all of the sites it reveals during its search, and it may index millions of pages a day. When you ask a search engine to find info, it is essentially looking through the index which it has made and not really scouring the Internet. Different search engines produce different rankings because not every search engine uses the same algorithm to search through their database.
One of the things a search engine algorithm scans for is the frequency and location of keywords on an web page, but it may also detect synthetic keyword stuffing or spam indexing. Then the algorithms investigate the way that page link to other pages in the Internet. By checking how pages link to one another, an engine can both figure out what a page is about, if the keywords of the linked pages are like the keywords on the first page.
