How Google Work

Link Popularity

If you have downloaded the Google toolbar, then you will have seen the green bar that Google uses to rank every site you visit. This ranking is Google’s PageRank, and is indicated on a scale of 1 to 10. Generally, sites with a PageRank of 7-10 are considered excellent in terms of quality and popularity. But how is this rank calculated? Quite simply actually. Google’s main criteria for the calculation of relevancy for a page is based on the number of web sites that link back to that particular site.


However, having 100,000 web sites linking back to your site will not necessarily mean that you will attain a PageRank of 10. Each site that links back to you must in itself contain quality content and have a high (7-10) PageRank for it to impact positively on the PageRank of your web site.

Yes, sites with a poor PageRank can bring your sites PageRank down. If Google’s PageRank technology sounds confusing, just try and remember that Google’s PageRank is the #1 criterion for calculating the relevancy of any web page in relation to the specified search term. We will come back to link popularity later.
Now, there are supposedly over 118 factors involved in exactly how Google calculates your Search Engine Rank Position (SERP), as mentioned above, Google places more emphasis on PageRank than other engines. We’ll also be looking at some of the other main factors in a later chapter.
