There are many search engines but, Google, Bing, and Yahoo are the most common. They all use different algorithms, but all take these essential factors into account:
The number of incoming and outbound links as well as their quality
Content relevancy in regards to the search query
HTML coding of the page and site maps.
Search engines have to garner detailed info from numerous web pages to deliver accurate results. They achieve this by utilizing programs called bots or spiders. These bots crawl all over the internet following hyperlinks and collecting information on the way. This data is stored in a database known as an index which is then optimized to receive relevant information when searched for through the search engines. Apparently, the search results depend on the engine’s algorithm. The algorithm ideally uses various strategies to rank web pages and then display them to the user in the results page.
However, it is worth noting that companies such as Google change their algorithm on a regular basis to prevent people from using unfriendly methods to override the system and rank higher in the search engine results page.
That said, it is important to create a site that’s fully optimized for the search engines. That implies using keywords within specified areas of pages to ensure that you rank higher on the results page. It’s also important to know what the bots are looking for. For instance, the text is a fundamental element of search engine optimization, and it has to be relevant, of high quality and updated regularly. Bots can tell if the book is old and thus not return to your website regularly. Avoid including too many flash plugins as they give the boys a hard time when crawling over your pages.
