Comment on WordPress SEO Plugins by Nissim Ziv.

WordPress SEO Plugins Thanks Dave for your answers,
Some other questions –
1. What plugins do you recommend to use (Alinks, Post easer, Related post, Popularity contest etc…)?
2. I understand that there are 3 ads (central, right and bottom), why you haven’t include the one on the left, where it’s seen in “adveture” website? It is one of the best locations.

3. can you give me a clue where to change the width of the clumns? style.php? do you recommend to do this change?
Thanks,
I have just passed the payment.
