Providing SEO services is not an easy task because the requirements are updated a lot and it is very difficult to cope with these requirements. In order to stay updated you have to do a lot of effort and that is why SEO services if properly conducted are highly paid. Good news is that not all the things are updated and somethings remain constant for all the times. Have you heard about the private blog network service? This is a great way to get onto the top page without delays. You get the result in a short period of time and if you want them not to be short term results you have to do a certain things. Not all bloggers know these things and that is why a lot of blunders are done in the meanwhile. A good blogger will keep an eye on all the things and that is how he keep on maintaining such a network for his clients. For a particular niche and a network, it is recommended not to use more than 15 businesses because more the business, more would be the back links produced and as a result more would be the chances of getting caught by the Google authorities. Google automatic system checks for the foot prints, if any, left behind by the bloggers and if anything suspicious is found, information is sent to the inspectors for a manual review. Manual review has more potential to identify things that is why it is highly recommended to do things in a way to avoid getting caught at the first instance.
