In the start of this year Google panda d and because of updating lots of changing were observed in the corporate sector. First of all let me tell you what really Google panda is? Google panda is the algorithm or for your ease we can say that it is the criteria of Google of searching for a keyword in the web and then give you results. So know you can simply say that Google has changed its searching criteria and made it more efficient.
Owning to the change in the Google panda lots of websites page ranks (PR) were decrease due to low quality backlinks and content. Due to the panda change lots of famous and well renowned websites go down in their Page Rank (PR) and you would be surprised that these corporate sector forced the Google's Executive Chairman Eric Schmidt to come into the court and take oath that Google has not done any illegal activities to down their website.
The websites with low quality backlinks and the copy righted content were especially ranked down. Here I would like to tell you which site gives you low quality backlinks. Google consider the low quality site which is full of ads you will find many sites with lots of ads block on them so webmasters should not leave the link there, usually Google consider the sites low quality if site has 5 or more than 5 ad blocks.
If a webmaster is publishing copy righted material from the other sites, it would also be a low quality website in the new Google panda . You would know that in the February 2011 lots of websites were ranked down in google search just because they have copy righted material. Here one thing is very important sometimes bloggers who have more than one blogs usually copy content from their other blog which is also consider as copy righted. So if you have more than one blogs or websites don’t copy paste content on both. Another most important thing to remember it that if someone is copying your content, it is also bad for you too.
Sometimes bloggers don’t care about the spam comments on their post but they should remember that lots of spam comments on your page will also decrease your site rank.
