Hello, I have been working in this SEO industry for more than 2 years. So far I did a great job in SEO. But in the recent days (1-2 weeks ago) started a drop in position of the keywords which I am working on. I couldn't understand this. Anyone please help me to figure this out?
Yes, there have been MANY follow-on Panda mini-releases. The first big one was in March (I think), but I know there were blog posts about Panda 2.0, 2.1 and 2.2 for several months after. I think I have a blog post on this if you are interested.
No there is no major change as such. Since the main update (in February and April), Google has been pushing small updates to the Panda filter all of which aim to improve Google search quality. - Panda Update 2.1: May 10, 2011 - Panda Update 2.2: June 16, 2011 - Panda Update 2.3: July 23, 2011, only minor changes have been made to panda algorithm
The theme is always the same, this latest update includes other elements that contribute to the improvement of search queries to distinguish between the Web sites of higher and lower grades.
