Best SEO Software? What say you ...

Hey everyone,

I have used various software and apps for SEO over the last couple of years.

WooRank
It was okay, but not detailed enough. For on-site, some of the metrics seemed really out to lunch. Off-site and link building really lack luster.

PowerSuite
So far, the best option we've tried, but there are a lot of errors that pop up every day, and their tools take days to run and get results back regarding campaigning.

AHREFS
This seems to be the most reliable back linking app, but if I check links on other platforms, it'll find links that AHREFS couldn't find, and visa versa.

So, what have you guys tried, and what works best for you?

You cannot get all the best things at one place.

Ahrefs: It's the best backlink spy solution available in the market.

CognitiveSEO: Those guys uses APIs of Ahrefs, Majestic, Moz and many others. So, you don't have to pay extra for each service.

Long Tail Pro: A good solution to do keyword research.
