With Penguin is the common problem that the whole site just drops a bit?
I was hit by Panda, and specific pages got hammered, while others actually improved. I am now seeing more or less the same percentage of visits to the most popular pages, but just fewer across the board.
This does make me think that my problem is that some old seo (directories etc) is just not working now, rather than I have been penalised specifically. But, no idea how to know!
I will carry on and focus on what I have been doing in the last 2 years (writing better content etc.) and hope that I get some new links that are liked more.
Still on first page for some important keywords (important in terms of sales) but dropping 3 places certainly hurts.
