Last year, Google made some significant changes to its ranking algorithm. The changes were designed to make the rankings harder to manipulate through bulk link building. Instead of simply looking at the quantity of incoming links that a website has, Google now also looks at the authority level of the linking website, the anchor text and several other factors.

If you have ever used link exchanges, automated directory submissions or paid link services, Google may be penalising you for having a lot of low quality links. The good news is that it is possible to recover your rankings if you show that you have taken measures to remove those links.
