Our Verdict — Best Of The Best

Price: Starts at $29/month

RankIQ is an amazing SEO tool that is full of actionable insights you can take to rank higher. We think it’s the best because of its powerful AI-based SEO tools, its content optimizer, and inviting price tag.

The Best Part:

  • No more guessing. With the “title optimizer” report, you’ll know which keywords you have to use in your titles, in order to get more organic clicks.

The Worst Part:

  • Could be restrictive for big agencies. If you’re a big agency with tens or hundreds of clients… Then RankIQ may be a bit restricted, with the limit of 80 keyword reports per month.

Get RankIQ if you want the absolute best SEO tool.

I recommend you get started with the Lite plan for $29/month.
