The Google Algorithm is a system that the search engine uses to determine what search results are ranked high. It is used by Google to rank websites and pages that are useful and relevant to what the searcher is looking for. The algorithm works on three levels. These are the algorithm developers, software that determines which sites get the top ranking and the editors who choose which sites make it to the top of the rankings.
The algorithm developers create the algorithms that determine which pages rank high. This includes how much weight the algorithm puts into a particular factor. This factor is related to how important the page is in relation to other pages. Some factors are more important than others.
Many sites have very similar rankings. For example, if a site is used for the same purposes as an eBay site, a site like Amazon will also be used for the same purposes. With the existence of all these sites, there is no way that anyone can really tell which of these sites is the most popular. And yet they are ranked based on popularity alone.
In addition to the algorithm developers, there are many programmers who are trying to develop the algorithms that are used to decide which sites get to stay in the top rankings. These programmers have made their own variations on the basic algorithms that appear on the first page of the search results. They then compete with one another to come up with the next best versions of these algorithms. The only difference between these algorithms is that some of them are more complicated than others.
Every website that is used to generate search results must be ranked. This is done by algorithms that are tweaked at times to determine which sites are ranked where. That will depend on what the algorithm looks for in a site.
The Google Algorithm has been modified several times to increase the weight given to each factor that was once given as much weight as it had previously. But, there is a limit to how much a single factor can affect the rankings of a site. A person who wants to get a higher ranking is going to have to go through all the factors that are considered and hope that they are well weighted enough to push the website higher.
When a site is submitted to Google for a different search, the page is not the same all the time. Different search engines will send the site to a different search result. Sometimes the website is placed in the second page of the results when it should be at the first page. This is because the algorithm does not look at every page.
When the algorithm is being tweaked, the page can change as well. The algorithm can be changed if the people who design the algorithm feel that the site that the website ranks is not very relevant to what the searcher is looking for. Sometimes they can simply do this by tweaking certain things so that the site gets a higher rank.
There are a number of search engines that the algorithm will be evaluated on. These include AOL, Ask.com, Ask Jeeves, Amazon.com, Ask Women, CNet.com, Costip.com, CNET News, CNN.com, eBay.com, eBizRate.com, Expedia.com, EzineArticles.com, FoxBusiness.com, Yahoo.com, ZDNet.com, and Yahoo News. Each of these are in some way related to search engines. So it is not a surprise that they are also part of the algorithm that determines rankings.
Not every page that gets reviewed is part of the algorithm. Some sites may get the highest rating because they have high traffic. But the algorithms are not purely for rankings. There are times when they have to be adjusted based on how they affect the usability of the website or how they can change the manner in which a site is viewed.
Algorithms using algorithms have become more important in recent years. They help to speed up the search process by sending people directly to pages that are relevant to what they are looking for. Many sites that get good results will have very high rankings, but are not exactly what the searcher was looking for. The algorithm helps them reach those sites.
