Every since the Last Penguin updates last March a number of business's have been severely impacted by the algorithm changes. One of my sites was badly effected and at one stage I was ready to just drop the site altogether. With it being 500 pages it would have been a challenge to redesign and change content. However over a period of 2 months I worked on the title tags and Meta Descriptions as Google Master tools did indicate there was some Duplicate content - in the last few weeks it does look like its starting to re-vitalise and the hits are slowly coming back in.

I am just wondering is this because of my changes or is the last algorithm tsunami now settled and tweaked by Google? What is your performance like now compared to last march?
