PageRank is how Google uses to determine the importance of a web page. It is one of the factors used to determine which pages appear in search results.
History of PageRank
PageRank was developed by Google founders Larry Page and Sergey Brin at Stanford. At the time of met Page and Brin, Search engines usually sent by pages that had the highest density of keywords, which meant that people could play with the system endlessly repeating the same phrase to attract a greater number of search results.
Stanford is patented PageRank and the name was probably attributed by Larry Page.
What Measures PageRank?
PageRank measures the importance of a web page.
Theory of Page and Brin is that the most important pages on the Internet are pages with the most links that lead to them. PageRank see links as votes, so a page with links to another page is calculated as a vote.
This makes sense, because people tend to give link to pages with relevant content and pages with multiple links to them are usually better sources than the pages that do not send one link.
PageRank does not stop there. It looks as well at the importance of the page that contains the link. Higher PageRank pages have more weight "voting" that lower PageRank pages. Also concerning the number of links on a page that offers "the vote". Pages with many links have a lower importance to vote.
It also has meaning. Pages that are important are probably the best authorities to lead Internet users for better sources and the pages having more links probably are less selective about the pages that give link.
How Important Is PageRank?
PageRank is one of the factors that determine where your page appears in search results, but if all other factors are equal, PageRank can have a significant impact on the classification of Google.
There are deficiencies in PageRank?
There are certainly flaws in PageRank. Now that people know the secrets to getting a high PageRank, data can be manipulated. Google Bombs are classic examples of manipulating PageRank.
"Link farming" is another method which attempts PageRank manipulation. "Link farming" is the practice of linking pages with no connection to relevant pages, often this process is automated. If you ever surfed on a web page that had nothing but a collection of random links to other sites, be sure that you landed in a links farm.
Google has adapted its calculations to filter possible links farms. This is one of the reasons why registering your site to directories with low or no PageRank can be a bad idea.
If you find your site with a link farm links, do not panic. In most cases this has no effect in all classifications. However, you can not control who give link to your website. Just do not give link to such a farm and not intentionally enter your site on a links farm.
How Can I See The PageRank?
PageRank is measured on a scale from one to ten and is designated individual pages of a website, not the entire website. To check the PageRank of a page, use the Google Toolbar. Very few pages have a PageRank of 10, especially as the number of pages on the Internet is growing.
How Can I Increase The PageRank Of The Page?
If you want to increase the PageRank of your page, you must have "back links" (links to your site), or other person to give link to your website. You can change links with others, but make sure you provide only relevant links exchange, but especially make sure you do not change links with a link farm. You can register your website in directories such as the Open Directory Project, but use high PageRank directories whenever possible.
As you do web pages within your site, you can create some own back-links providing links to relevant pages of your own site. This technique you will be able to see right on this website. In any case, remember that the number of links created enter into an equation. Do not abuse.
The best way to increase your PageRank is to have quality content that others want to give link.
