With the recent disappearance of some valuable free SEO tools such as Yahoo site-explorer and some SEO tool providers turning to (often expensive) paid-only subscription plans we decided to dig deep and find the best SEO tools that are 100% free. After all we’re not all connected to large SEO service companies with deep pockets or SEO professionals per se.

So after some research here is the list of the top best, totally free, SEO tools of the current moment. (So no 30-day trials etc)

List of Free SEO Tools

#1 SEOBook tools

http://tools.seobook.com/

SEOBook is the creator of what must be one of the most popular tools among SEO’s: The SEO Toolbar FireFox extension.  Some of the functionality and metrics included in this tool: Google PageRank, incoming link count, traffic estimates, rank-checker, on-page keyword analysis, nofollow link highlighting and more. The only downside is that the toolbar is only available for FireFox.

Furthermore they offer a whole bunch of web-based SEO tools.

#2 SEO Power Suite

Link-Assistant.com offers a software suite called SEO Power Suite. The suite consists of four programs, LinkAssistant, Rank Tracker, SEO SpyGlass and Website Auditor.

At a first glance it isn’t clear wether the Free license is time-limited, but this is in fact not the case.

The free license has some limitations but is still an excellent addition to your toolset! Check out the limitations of the free version here and then give it a spin!:

#4 Backlink Watch

Simple web-based tool for finding your (competitor’s) backlinks. Don’t get too distracted by all the ads, this is actually a very decent tool!

#5 AHrefs.com

https://ahrefs.com/site-explorer/

The AHrefs.com site-explorer is a good alternative to the once popular Yahoo Site  Explorer. When you sign up for a free account (paid plans start at $79 monthly) you’ll have access daily to 15 Requests, 500 Results / request, 3 Standard reports / day, which in practice is quite limiting. As it is such a powerful tool we include it nonetheless.
