Summary

SEO is a huge industry, and it's no wonder, good SEO is one of the cheapest marketing channels that you can do.

Unfortunately there is a lot of crappy tools out there. Normally, you wouldn't care...if it doesn't work you just throw it out and move on. But SEO is different...crappy tools can get your site penalized and all your hard earned work can disappear over night.

This is why it's so crucial to pick the right tools for the job.

One of the best packages for SEO, is offered through Moz(formely known as SEO Moz). With them you can take your SEO to unheard of heights without worrying that you'll be ruining all your hard work in the process.

Value

This service starts off at $99 a month which is really nothing. You will more than cover that cost by simply gaining a single position on a single keyword. .

The Good
They'll give you actionable insights into your SEO strategy and will help you take your SEO to the next level. They also do their own crawling, so they use their own real time data instead of using Google's public data that's months out of date.
The Bad
The tools just give you information, you have to do your own link building. They've been debunked a few times by Matt Cutts for posting incorrect things on their blog(that Facebook and Google Plus likes improve SEO).
