Google have announced that the Panda update which was designed to provide higher quality sites in the search results that hit the USA a few months ago has now been rolled out globally to all English language based users.
As part of this stage of the roll out Google have now introduced user feedback signals to help people find better search results. With regards to the new user feedback signals I can only assume at this point that factors such as landing page bounce rates, time on page *could be* looked at as well as several other factors.
Google go on to state that;
In addition, this change also goes deeper into the “long tail” of low-quality websites to return higher-quality results where the algorithm might not have been able to make an assessment before. The impact of these new signals is smaller in scope than the original change: about 2% of U.S. queries are affected by a reasonable amount, compared with almost 12% of U.S. queries for the original change.
This morning I have spent some time looking at previous clients sites as well as existing ones and have noticed no significant change in their listings. That said I have seen an increase in competitor sites for some high volume generic terms.
I think once the hype has settled and we have a week or maybe more of data we will be able to see the impact this will of had on the sites we look after.
