Pagerank: Why is it important?

Pagerank is a score given to each webpage on the WWW by Google. This score has several applications in the e-marketing world, for the following reasons:

1) a website or webpage with high pagerank climbs it up to the first positions in Google's indexes when a common web user does a search engine search. That means that a company whose website has higher pagerank can get more visits and more chances to see its products sold;

2) some websites try to get high pagerank not just to rank better in search engines, but also to increase the website popularity and get affiliate returns to it.

Overall, webmasters nowadays really care about the whole Pagerank matter, but you should never underestimate the value of the other ranking tools, which are: Alexa, Technorati and Yahoo backlinks. I'll talk about them in my next entries.
