The 55 Best Free SEO Tools For Every Task

Posted by Cyrus-Shepard

At Moz, we know the value of premium SEO tools — we’ve
built new tools for 10+ years. Paid tools are hugely valuable in
SEO when you need advanced features, increased limits, stored data,
or online support.

But for 70 percent of other tasks, a free tool often does the
There are literally hundreds of free SEO tools out there, so we
want to focus on only the best and most
useful to add to your toolbox. Tons of people in the SEO

The best tools to analyze search performance, monitor SERPs,
keywords, and competitor analysis:

1. Bing Webmaster Tools

While Google Webmaster Tools gets all the glory, folks forget
that Bing Webmaster offers a full sweet of website and search
analytics. Especially useful are keyword reports, keyword research,
and crawling data.

Get it: Bing
Also useful: Yandex.Webmaster

2. Data Studio

If you need to merge data from different sources (say Search
Console and Google Analytics), visualize, and share it – this is

4. Google Analytics

The big kahuna, and the most widely-used web analytics package
on earth. For being free, Google Analytics is surprisingly robust
and plays well with other Google products, including Optimize,
Search Console, and Data Studio. Some folks have privacy concerns
with GA — though Google swears they don’t use this data for
search rankings.

Get it: Google
Clicky, Open Web Analytics

5. Search Console

Probably the most useful free SEO tool on this entire list, it’s
hard to imagine doing modern SEO without access to the data inside
Google’s Search Console. This is the most reliable location for
information on how Google crawls and ranks your site, and is one of
the only places where you can get reliable keyword data.

Get it: Search

6. Keyword Hero

Did somebody say (not provided)? Keyword Hero works to solve the
problem of missing keyword data with lots of advanced math and
machine learning. It’s not a perfect system, but for those

9. Link Redirect Trace

A free Chrome extension, lots of SEOs recommend Link Redirect
Trace as the “all-in-one redirect path analyzer.” The extension
reveals information about HTTP headers, rel-canonicals,
robots.txt, and basic link metrics from LinkResearchTools. The
“Save Screenshot” feature is super useful too.

10. Redirect Path

Similar to Link Redirect Trace, Redirect Path is a nifty tool
from the good folks at Ayima that shows redirect paths and
header information for every URL you visit. Gotta admit, I’ve used
this extension for years and it’s almost “always on” in my

11. Screaming Frog

Aside from having one of the best Twitter accounts of any SEO
tool maker, Screaming Frog is the most popular desktop-based
crawler available today. Many people don’t realize that there’s a
free version that allows for up to 500 URLs per crawl. While not as
fully functional as the paid version, it’s great for small projects
and smaller site audits.

12. Screaming Frog Log File Analyzer

14. Xenu

Gotta be honest, although Xenu has been on every “free SEO tool”
list since the dawn of, no way did I think it would make this one.
This Windows-based desktop crawler has been virtually unchanged
over the past 10 years. That said, a lot of folks still love and
use it for basic site auditing, looking for broken links, etc.
Heck, I’m leaving here for sentimental reasons. Check it out.

Google’s own Keyword Planner was built for folks who buy Google
ads, but it still delivers a ton of information useful for SEO

which is known to be confusing.

18. Keyword Shitter

Sometimes I make fun of Neil Patel because he does SEO in his
pajamas. I’m probably jealous because I don’t even own pajamas.
Regardless, Neil took over Ubersuggest not long ago and gave it a
major overall. If you haven’t tried it in a while, it now goes way
beyond keyword suggestions and offers a lot of extended SEO
capabilities such as basic link metrics and top competitor

careful and check with this guide on disavowing the
