25 AMAZING Free SEO Tools [2020 Reviews]

This is a list of the 25 best free SEO tools on the planet.

In fact, these tools have helped my site get 299k+ visitors per month.

Backlinko – Monthly users

(Most of which came from SEO)

The best part?

All of these tools work GREAT in 2020.

Let’s get started…

25 Best Free SEO Tools

1. Answer The Public

Find 150+ keyword ideas in seconds.

Most SEO tools get their data from the same place: The Google Keyword Planner.

Answer the Public is different.

This awesome tool finds questions that people ask on forums, blogs and on social media.

And it turns those questions into awesome keywords:

Answer The Public – "keto diet"

Best Feature: “Vs. Keywords”

You’d be surprised how many people search for “X vs. Y” keywords in Google.

(For example: “iPhone vs. Android” or “SEMRush vs. Ahrefs”)

And Answer the Public has a section of the results dedicated to “Vs. Keywords”.

Answer The Public – "keto diet" – Versus section

Which brings us to the 2nd tool on our list…

2. Woorank’s SEO & Website Analysis Tool

Get a list of SEO improvements in seconds.

This is a very handy Chrome extension.

First, you get an overall SEO score.

Then, the tool shows you EXACTLY how to improve your site’s on-page and off-page SEO.

WooRank – Chrome extension

Best Feature: “Marketing Checklist”

Most SEO tools only tell you about problems… not solutions.

But with Woorank you get a detailed SEO checklist that you can use to fix any issues that you run into.

WooRank – Marketing checklist

And now it’s time for our next free SEO tool…

3. Animalz Revive

Improve and update old content.

Animalz Revive helps you find older content on your site that needs an update, an upgrade… or both.

Before this tool, you had to manually comb through your Google Analytics account to find these pages.Which was a giant pain.

Fortunately, this tool tells you exactly which articles on your site need the most attention.

Animalz Revive Advice

Best Feature: “Traffic Loss Since Peak (Views)”

This feature lets you know exactly how many visitors that a piece of outdated content is costing you.

Animalz Revive

4. CanIRank

Quickly answer the question: “Can I rank for this keyword?”.

CanIRank is a super-detailed keyword difficulty tool.

And unlike most free SEO tools, CanIRank doesn’t give you generic advice like:

“This keyword is really competitive”
Or
“This keyword has low competition”

Instead, it tells you whether or not YOU can rank for that keyword.

CanIRank

Very cool.

Best Feature: “How can you better target this keyword?”

CanIRank isn’t just for sizing up the first page competition.

It also gives you suggestions that can help you rank for a specific term.

CanIRank – Keyword probability

5. Google’s Mobile-Friendly Test

Get your site ready for Google’s Mobile-first Indexing.

You might have heard that Google recently made a big change to their algorithm.

(This change is officially called “Mobile-First Indexing”).

The bottom line is this:

If your site isn’t optimized for mobile devices, you’re in big trouble.

Fortunately, you don’t need a full-time developer to make your site mobile-friendly. All you need to do is run your site through the Mobile-Friendly Test tool.

And it tells you whether or not Google considers your site mobile-friendly.

Google Mobile-Friendly Test

Best Feature: “Page loading issues”

This feature shows you how you can improve your site’s code. That way, Google’s mobile crawler can find and index all of the resources on your site.

Mobile-Friendly Test – Issues

6. Seed Keywords

Find completely fresh keyword ideas.

Most keyword research tools work the exact same way:

  1. Enter a seed keyword into the tool.
  2. Get a list of closely-related terms.

The problem with this approach is this:

Everyone types the same seed keywords into these tools.

Well, Seed Keywords takes a completely different approach.

Instead of pulling seed keywords out of thin air, you ask your customers how they’d search for you online.

SeedKeywords – Scenario

Then, type those seed keywords into your favorite keyword research tool.

Best Feature: “Submit Query”

Once the results come in, you can use SeedKeywords to do a Google search for the keywords that people gave you.

That way you can quickly scan the search results… and see how competitive that keywords is.

SeedKeywords – Results

7. Exploding Topics

Find popular keywords before they get competitive.

This free SEO tool does one simple thing:

It bubbles up topics that are just starting to trend.

exploding topics Homepage

That way, you can create content around these emerging trends (or optimize your old content around a new keyword).

The tool currently has about 2k topics in its database. And they’re adding more every week.

Best Feature: Categories

Categories lets you drill down to a specific topic category that’s important to your business.

For example, let’s say you run marketing for a skincare brand. Well, you’d hit “beauty” and get a list of emerging topics in that space.

exploding topics Category Page

Nice.

8. Seobility

Get a deep-dive SEO site analysis.

SEObility crawls your entire site and lets you know about search engine optimization issues like:

SEOBility

You usually only get this type of stuff from paid SEO tools. So it’s really nice that Seobility gives you this data for free.

Best Feature: Content Report

This report hands you a list of pages that have content-related SEO issues.

(Things like: thin content, missing meta titles, keyword stuffing, and duplicate content)

SEOBility - Content report

9. Ubersuggest

Get keyword suggestions and competition data.

Ubersuggest has a lot of features that are usually only found in premium SEO tools.

But it’s 100% free.

To use it, type in a keyword that you want to rank for (or a competing website that you want to rank above).

Ubersuggest – Search

And Ubersuggest will give you detailed data on keyword difficulty, monthly search volume, and more.

Ubersuggest – Results

Plus, you get a list of suggested keywords that are based on the keyword you typed in.

Ubersuggest – Keyword suggestions

Best Feature: “Comparisons”

This feature shows you “X vs. Y” keywords.

Ubersuggest – Keyword comparisons

In my experience, X vs. Y keywords are super untapped.

Sure, they may not get as many searches as traditional keywords. But they’re SUPER targeted and high-converting.

And to my knowledge Ubersuggest is the only tool that specifically bubbles up X vs. Y keywords.

10. BROWSEO

See your site through the eyes of a search engine.

As it turns out, search engines see your site VERY differently than you do.

And BROWSEO gives you the type of x-ray vision that search engines have.

BROWSEO

Best Feature: SERP Preview

Get a sweet preview of how your page appears in the search results:

BROWSEO – SERP preview

This is helpful for figuring out if your title and description tag are SEO-friendly (or too long). And optimizing your title and description can also help you get more organic clicks.

11. Detailed.com

Get intel on your competition.

Detailed gives you a curated list of the most popular sites in your industry.

That way, you can size up your biggest competitors.

(And copy what they’re doing)

Detailed

Best Feature: “Mentions”

This features shows you who recently linked to (and tweeted about) your competition.

Detailed – Backlinko

12. Google Search Console

Get SEO help straight from Google.

No list of free SEO tools would be complete without the Google Search Console.

Why?

The GSC is a VERY feature-rich piece of SEO software. And unlike pretty much every other tool on the market, you know the data is legit.

(After all, it comes from Google)

For example, you can use the Google Search Console as a rank tracker to check your site’s rankings in the SERPs.

Using Google Search Console as a rank checker

Best Feature: Index Coverage Report

13. SERPerator

This awesome tool lets you check the SERPs across different locations and devices.
As you probably know, the search results change dramatically depending on where you are and what device you’re using.

(Especially for local searches, like: “pizza shop” or “landscaper”).

And this tool lets you see exactly how the results will look for someone searching on a particular phone from pretty much any major city in the world.

Best Feature: Compare Devices

14. Screaming Frog

Let’s face it:

Finding technical SEO problems on your site can be a HUGE pain.

Enter: Screaming Frog.

This nifty tool crawls your site using a Google-like crawler. And it generates a report of potential issues (like HTTP header errors, javascript rendering issues, bloated HTML, and crawl errors).

Screaming Frog

Best Feature: Discover Duplicate Content

As you might have heard, Google HATES duplicate content.

Fortunately, you can use Screaming Frog to quickly ID pages with duplicate content.

Screaming Frog – Duplicate content

15. Google Analytics

See how people find and interact with your site.

OK, OK. Google Analytics isn’t really an SEO tool.

But it’s almost impossible to run an SEO campaign without it.

Why?

The data in Google Analytics tells you whether or not your SEO efforts are paying off.

I’m talking about data like:

  • Organic traffic
  • Bounce rate
  • Traffic sources
  • Time on site
  • Page speed
Google Analytics

Best Feature: Google Analytics and Google Search Console Integration

Google Analytics is super powerful on its own.

But when you combine it with the Google Search Console?

It’s even MORE powerful.

Linking your GSC account with GA hooks you up with helpful info, like the keywords people use to find your site, your organic CTR, and more cool stuff.

Google Analytics – Google Search Console

16. Reddit Keyword Research Tool

This is one of my favorite little keyword research tools.

Why? Because it can bring up terms that I probably wouldn’t find with any other tool.

This tool scrapes Reddit words and phrases that tend to crop up in specific subreddits.

So if you know where your target audience hangs out on Reddit, this is a goldmine of keyword and content topic ideas.

If your site runs on WordPress, you need to install Yoast ASAP.

It’s by far the most robust SEO plugin on the market.

The best part? It’s 100% free.

Sitemaps help Google and other search engines find, crawl and index all of the pages on your site.

And with the Yoast plugin, you don’t have to tinker with your sitemap every time you add a new page to your site.

That’s because Yoast updates your sitemap automatically. Cool.

18. Panguin Tool

Get to the bottom of a rankings drop.

This tool correlates your search traffic with known Google updates.

Why is this helpful?

Well, if you notice that your rankings dropped around the time of a big Google update, you can figure out what went wrong… and fix it.

Best Feature: Switch Updates On/Off

Panguin makes it easy to zero-in on a specific update.

For example, if you’re a local business that focuses on local SEO, you can only have Panguin ONLY show you Google updates that impacted local results.

Panguin – On/Off

19. Wordtracker Scout

Steal your competitor’s keywords.

Wordtracker scout takes a unique approach to keyword research…

Instead of entering keywords into a tool, Wordtracker shows you the most common terms on a page.

That way, you can go over to one of your competitor’s pages… and grab the keywords they’re using in their content.

The best part of KWFinder is how darn easy it is to use.

But don’t let this fool you into thinking KWFinder isn’t powerful. It’s a legit keyword tool that lots of pros use.

KWFinder

Best Feature: LPS

LPS=Link Profile Strength.

This feature basically tells you how many links you’ll need to rank for that keyword.

So if you find a keyword that has a LPS of 50+, you know that you’ll need to do some serious link building to rank for that term.

KWFinder – LPS

25. People Also Ask

This free tool pulls questions that appear in the “People Also Ask” section of Google’s search results.

Usetopic – People Also Ask

My only gripe with the tool is that it takes a while for the results to load. But I understand that’s because it has to actually run the search and grab questions from the PAA box. Which takes a while.

Overall, a very cool tool for finding question keywords.

Best Feature: Related Questions

People Also Ask shows you questions that you’d usually have to get by manually clicking on the PAA box in the SERPs.

For example, one of the questions the tool showed me was “What is a good keyword?”. And I also got a handful of questions that were closely related to the original question.

People Also Ask – Related questions
