Google, Yahoo, and other Search Engines have not only expressed how important a quality number of backlinks are for your sites presence on the web. They have also stated how important it is that those links come from quality websites that also follow standard SEO guidelines. Thats exactly what you get from TheNetDB.
Google does not deny the importance of one way links and external links. Google assigns a rank to all sites on the internet and the higher rank of sites linking to your site will increase your pagerank. It is also important that you keep the number of external links relatively low because those can reduce your pagerank.
So how long does it take google? Google releases no information on how often the page ranks are updated. However it is estimated that they do this every 80 – 140 days. Don’t be impatient just follow these guidelines and you’ll have high pr sooner than later.
