What Wordpress Plugins Do You Recommend For An SEO Consulting Site

I offer SEO services primarily on my wordpress theme and I'm trying to figure out which plugins are best to generate more leads and customers. What do you guys recommend? Paid or free it doesn't matter.
:thanks:

Also interested to hear some responses! Nice Thread!

SEO Search Terms Tagging 2 is the only one I can think off...
Possibly CTR maximizer....

Try my plugin Automatic Post Tagger. You can find it in the official repository.

The standard plugins like WP Super Cache and minify will also be helpful.

Studies on the correlation between load time and conversions show a strong relationship so make sure that you aren't ignoring the basic factors that also contribute to user experience and site optimization. Try running Yslow for Chrome and go through the list to improve your page speed optimization.

There's nothing that turns people away faster than a slow loading website...
