Google Sitemaps enables Webmasters to Directly Alert Google to Changes and Additions on a Website and that’s just one of 7 Benefits.
Telling search engines about new pages or new websites use to be what the submission process was all about. But major search engines stopped using that process a long time ago.
Google has for a long time depended on external links from pages they already know about in order to find new websites.
I will try to draw conclusions from what I have learned so far about those three things, the Page Rank, Alexa Rank and SEO.
Page Rank is the value provided by Google with a number from 0 up to 10, to each page of our website. This value indicates how important our web value compared to the others. The greater the value we get, the better are the results of searches on Search Engines. One of the determinants of the value of Page Rank calculation is the number of links that lead to web pages.
Alexa Rank is a value assigned by Alexa which is calculated based on the number of visits and page views on our website, from all the websites that install the alexa toolbar. Alexa value is smaller the better, because it shows the high traffic and page views are obtained by the website. Alexa Rank determining factor is the number of visits and page views are obtained by our website.
What Is The Google Sandbox
The Google Sandbox is an algorithmic filter designed by Google and implemented around March 2004 with the purpose of weeding out spam sites by placing all new websites under quarantine for a period of assessment.
