If you’re serious about building high-quality backlinks for your site, Ahrefs is the tool you should invest in. Ahrefs has the best link index among all SEO reporting tools. You can use this tool to unearth your competitors’ backlink profile and build your own backlinks.

While the tool has evolved into a full-fledged SEO software, it’s still primarily known for its backlink analysis features.

#3 Moz

Moz Overview

Started by Rand Fishkin aka the Wizard of Moz back in 2004, Moz is perhaps the most popular SEO tool in this list, owing to the cult-like popularity of Fishkin in the marketing space.

Moz relies heavily on SEO metrics such as Domain Authority and Page Authority to give you insights on link equity, keyword rankings, page optimization reports, and more. Despite all these features, Moz has not evolved or improved much in recent years, especially since Fishkin’s departure from the company in 2018.

Moz: Final Verdict


Despite having a wealth of SEO resources on their blog and a top-notch YouTube channel, Moz is the weakest all-purpose SEO tool on the list. Since we are evaluating these tools on their features and pricing, and not the kind of content they produce, Moz is simply not worth paying $100 a month. I’d much rather spend that money on Semrush or Ahrefs.

SpyFu Reviews and Ratings

SpyFu: Final Verdict


SpyFu is a decent competitive research and keyword analysis tool. With paid plans starting at $39/month, it’s also one of the most competitively priced SEO products on the market.

Having said that, the tool certainly has limitations. The data you get is not always accurate and the UI looks and feels outdated. Nevertheless, if you want a reliable SEO competitor analysis tool that’s not too heavy on the pocket, you should try SpyFu.
