You aren't providing nearly enough information? What do you want the tool to do?

For instance if you run an agency and want rank tracking with nice clean agency reporting I would go with SEOMoz. If you want your focus to be on social media reporting I would do Raven Tools. If you want really really high quality rank tracking (ie. very high accuracy) I would go with Getstat.

All depends on what you are looking for and what your budget is.

Raven Tools & SEOMoz both are great SEO membership sites. However SEOMoz is having more content to learn and being updated with latest SEO Trends.

Out of these, only tried SEOmoz and they worked well at that time. No experience with the others. Would like to know the others opinion in case to give a try for another one.

Hello! In my opinion, Raven Tools is really amazing. It's the next best thing. You should give it a shot. I hope that helped you in a way or so. Best of luck!

I'm surprised SEO Powersuite is not on the list, its rank tracking feature totally rocks, and so does the backlink analysis module.

BTW, what is Lindex? I've never heard about it.

Rand Fishkin is an seo tool. (just kidding, not really)

Anyway, Raven Tools is pretty sweet.

SEOmoz is my favorite one.

Only thing good about SEOmoz IMO is open site explorer, and Majestic's index is way better. So go with Majectic. SEOmoz is mainly content, all of which is bs. Warrior Forums has all the info you'll ever need to learn and grow.

Raven rocks, and it's not just for social media, it does it all.

SEOmoz, i used this tools, very powerfull tools

It seems Raven tools give the best service. Thanks guys!!!

I would prefer SEO Moz
