Can anyone recommend a good SEO plug-in for WordPress? I have tried a couple but I have had marginal results. Any advice would be appreciated.

Yup, I use the "all-in-one" seo pack too... easy to use.

I found All-in-one-seo plugin is good but it leaves tags which tell rivals that I am using it, is there anyone can tell me how to remove it?
