Do any of you use any SEO apps or tools.
If so, what do you use?
What do you like about it?
Pros, Cons, etc

I would say most people with a decent web presence do. If you use wordpress you cant go wrong with Yoast or All-in-one seo. They’re both very popular and are a great addition to any website.

I like MOZ quite a bit.
