A page rank is a tool many search engines use to assign a certain value position, ranking the web sites. It is done by evaluating some factors of web sites' online activities and determining their value for online community users. Basically, a page rank tool brings to light a quantity and quality of sites' activities, traffic and contents; it determines the prestige and reliability of every site for online users. A page rank is a very useful tool not only for online users, but for site owners as well. With the help of, let us say, free Google pagerank checker, both online users and site owners may see the page rank of each site even without having to install a Google toolbar into their web browsers. Moreover, with the aid of a page rank tool site owners can track their sites' CTRs, traffic, user behavior, etc. Their page rankers supply them with an opportunity to fight search spamming, such as the paid link advertising, since some sites try to buy their way up by purchasing links on various sites. Moreover, this tool helps to cut down the number of sites, filled with link ads alone.
Recently, Google has developed new conditions for its page rank. It has actually taken some steps to make it stricter. The new page rank conditions involve a stricter approach to filtering out paid links and including such parameters for detecting the link quality as the links' history, the speed of link acquisition, the reliability of your link partners, etc. Building up its page rank, Google also monitors such things as the site click-aways from your site back to search results, the frequency and amount of your page updates, bookmarks and favorites, etc. Hence, you should be careful, handling some of these matters, for if you, for instance, make a mass upload of files, the page rank radar will get you on. Nevertheless, if the amounts of your site upload are too insignificant, your ranking may slide down. Some online markets do not require any site updating to be done and this is taken into consideration in the Google page rank tool as well.
Another feature of the page rank is that a position you take may depend on the season of the year. For instance, winter season sports sites, such as skiing or skating products, or thematic sites' ranking may go down during the summer season and go up during the winter one. Such things as a rapid disappearance of certain topics on your site, or, on the contrary, a rapid increase of them may become an indicator for the Google page rank of search engine spamming. If certain documents or files on your pages remain stable for a while and relate to a certain topic, but then they rapidly change or increase, it may also indicate to Google of possible spamming activities. Therefore, the quality and stability of your site may be even more important than the quantity of its information and links.
Certainly, such things as keyword changes and density or technical and admin contact details are tracked and checked for consistency. As you may see, a page rank tool provides users with a better quality of online search results and drives site owners to use more legitimate means for their site promotions.
