PageRank is a numeric value that represents how important a page is on the web. Google figures that when one page links to another page, it is effectively casting a vote for the other page. The more votes that are cast for a page, the more important the page must be. Also, the importance of the page that is casting the vote determines how important the vote itself is. Google calculates a page's importance from the votes cast for it. How important each vote is is taken into account when a page's PageRank is calculated.
PageRank is Google's way of deciding a page's importance. It matters because it is one of the factors that determines a page's ranking in the search results. It isn't the only factor that Google uses to rank pages, but it is an important one.
From here on in, we'll occasionally refer to PageRank as "PR".
But what about PageRank, how much of it do I really need to get my site noticed? For those who are not familiar with the PageRank system. Google supplies a tool bar which you can download and install on your browser. If you make a complete installation with all the advanced features, then every time you open a new website you will see a green and white bar with the label PageRank. Put your mouse on the bar and you will see a number from 0 to 10. If a website is not indexed by Google or banned by Google, the bar may be grey or all white.
But what do the numbers mean? I had a client who was worried about his number 3 PageRank figure and based on my observation I answered him with my unofficial view on the rankings. Here is how I currently see it:
PageRank 0-2 shows that a site does not have many links and needs work, However, and this a big "however," it may not really affect your search engine rankings. I have a client with a page rank of 2 and his site ranks well, even number one, for several search terms in a fairly competitive industrial category. So PageRank is not everything; it may have an impact on your rankings and traffíc, but in some cases it may not matter. In any case if you have a PageRank of 0-2, you can work on it through proper link building activity which I will explain at the end of the article.
PageRank 3 can be OK in some cases but in highly competitive industries you should work to improve it.
PageRank 4 is quite a normal number and indicates that you have enough links in either quantity or quality to make your site competitive.
PageRank 5 indicates that a site has many links or links from authoritative sites, and that Google has good "trust" in the site. It is a respectable and attainable PageRank.
PageRank 6 is very difficult to attain. This rank indicates that the site has many links and links from respected places. Remember the example of www.bobdylan.com, which I mentioned above; it has a PageRank 6, so you can get an idea of the difficulty involved.
PageRank 7-10 is usually earned by large and established institutions or websites which have tremendous authority, due to the quantity and quality of the incoming links. It is extremely difficult to attain this ranking. You really have to be special to get it.
IS GOOGLE PAGERANK STILL A VALID MARKETING TOOLS?
So, don't worry excessively about PageRank. First look at your traffíc, then look at your salës and finally at your bottom line. They are the important numbers to watch. If you want to íncrease your traffíc and also PageRank, then here are a few steps that you can take:
1. Add content to your website. Make your website so good and so useful that people will link to you without you asking for a link.
2. Write articles and get them published on other websites and blogs with a link back to your site.
3. Distribute online press releases
4. Judiciously exchange links, or even better, exchange content (containing links back to your site) with other websites.
5. Get your site listed in online directories.
