Google is by far the most important search engine on the net. To rise to the top of their search engine, you need to improve your link popularity and you need to understand how they measure your link popularity (over 50% of all search engine traffic comes from Google, and if you can rise to the top, you will likely rise to the top of all the other search engines as well).

Link popularity is defined as the number of sites that are linking to your site. Some websites have thousands or even millions of sites linking to them, while others might have only a few. The search engines use the number of inbound links your site has as a measure of how important your site is, which translates into your search engine ranking.

The actual number of links to your site is not the only variable used to calculate your link popularity. The search engines also examine the relevance of the links to the subject matter of your site.

It is possible for a website with a relatively small number of quality inbound links to be ranked higher than a site with a bunch of irrelevant or insignificant links.

Now that we understand what link popularity is and how it works, we need to look specifically at how Google measures it. They use a number of variables in their algorithm to calculate your overall link score. The higher your score, the higher you will be ranked in the search listings.

One factor that Google uses in their algorithm, obviously, is the total number of sites linking to you. The more links you have, the higher your score will be. However, their algorithm is a little more complicated than that, and it is possible for a website with fewer links to be ranked higher than a website that has more links.

Another factor used by Google to score your link popularity is the diversity of keywords contained on sites linking to you.
