25 AMAZING Free SEO Tools [2019 Reviews]

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

In fact, these tools have helped my site get 200k+ visits per month.

(Most of which came from SEO)

The best part?

All of these tools work GREAT in 2019.

Let’s get started…

25 Best Free SEO Tools

1. Answer The Public

Find 450+ of keyword ideas in seconds.

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

Answer the Public is different.

This nifty tools finds questions that people asks on forums, blogs and on social media.

And it turns those questions into awesome keywords:

Answer The Public – "content marketing"

Best Feature: “Vs. Keywords”

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

(For example: “iPhone vs. Android”)

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

Answer The Public – "content marketing" versus keywords

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.

What’s cool about Woorank is that it hands you an actionable 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. And it was a giant pain.

Fortunately, this tool tells you exactly which articles on your site need TLC.

Animalz Revive Advice

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

This features lets you know exactly how many visitors you’re losing by not updating your content.

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 tools, CanIRank doesn’t just tell you:

“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 in-depth suggestions to 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 get ready for this update. All you need to do is run your site through the Mobile-Friendly Test tool.

And it tells you whether or not your site is prepared for Google’s new algorithm:

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. SEMRush

Copy your competitor’s best keywords.

SEMRush might be my all-time favorite SEO tool.

It’s got a paid plan with lots of awesome features.

But the free version is pretty cool too.

Whether you go with free or paid, SEMRush works the same way:

It finds the exact keywords that your competitor’s rank for.

SEMRush

Best Feature: Keyword Magic

Enter a keyword…and get a list of 78,350 keywords!

SEMRush – Keyword Magic

Insane.

8. Seobility

Get a deep-dive SEO site analysis.

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

  • Slow loading pages
  • Blocked pages
  • Sitemap problems
  • Technical SEO issues
  • Lots more
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

The Index Coverage Report gives you a list of pages on your site that aren’t getting indexed.

You can also see how you can get things back on track.

Google Search Console – 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.

SERPerator – iPhone results

Best Feature: Compare Devices

See how the results look on two different mobile devices… side-by-side.

SERPerator – iPhone, compare devices

14. Screaming Frog

Find and fix technical SEO issues in seconds.

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. Keys4Up

Generate a list of untapped keyword ideas.

Keys4Up uses a proprietary algorithm to generate “lateral” keyword ideas

For example, when you type “Content Marketing” into the tool, you DON’T get a list of variations of that term.

(Like: “Content marketing strategies”).

Instead, you get keywords that people would associate with that term:

Keys4Up

Best Feature: Keyword Export

The one downside of Keys4Up is that you can’t see how many people search for the keywords that it gives you.

Fortunately, you can export your keywords to a CSV… and upload that CSV to another SEO tool that does provide monthly search volume.

Keys4Up – Export

17. Yoast WordPress Plugin

The best SEO plugin for WordPress.

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.

Yoast

Best Feature: XML Sitemap Generator

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.

Yoast – Sitemap

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.

Panguin

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.

WordTracker Scout

(Note: This is only available as Chrome extension and isn’t supported for Firefox)

Best Feature: Opportunity

Shows you which keywords on your list has the best ratio of search volume and competition.

And unlike the Google Keyword Planner, the data from Bing is strictly for organic search (not Bing PPC or Adwords).

22. Dareboost

Analyze your site for speed, SEO, security and more.

Dareboost isn’t strictly an SEO tool.

Siteliner – Comparison with other sites

24. KWFinder

No-nonsense keyword research tool.

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

But don’t less 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. Varvy SEO Tool

Get a free SEO site checkup.

Varvy is an extremely cool SEO audit tool.

Most SEO analysis tools only give you surface level info.

    1. Good question. Not really. Because this post only lists 25 tools I have room to dig deep into each one. It’s more for people that are closer to choosing a tool (the other post is mostly for people that want an overview of all of the SEO software on the market).

    1. You can use TubeBuddy for YouTube for FREE, and VidIQ for free on YouTube as well. You can go on YouTube and search for videos on how to rank on with these tools to get a better understanding of how to use them. They are GREAT tools to use!!!

  1. Hi Brian,
    Really nice post as usual.
    I use few tools from the list you described in this post. Such as, Google search console, Ubersuggest, SMERush, Google Analytic, KWFinder, etc.

    Some of the tools you listed here I don’t even know about.

    This list of tools will certainly help them who want to dig deeper into SEO.

    Thanks for sharing this awesome list.

  2. Hey Brian huge fan of the blog. I’m an SEO Consultant for Screaming Frog. Another nifty feature:

    You can sort pages by the number of internal links pointing to them, so you can see what pages are valued the most on a site.

    Great for finding content that could be bested with the skyscraper method and keywords!

  3. Hi Brian,

    Thanks for this impressive list.

    SimilarWeb browser extension is also an important free tool for determining the traffic on a site and other things of the sort.

  4. Hi Brian,

    Thanks again for sharing great tools with detailed information. I use few of them like Keywords Everywhere, Yoast SEO, Google Analytics, Google Search Console, Answer The Public. Keywords Everywhere and Answer The Public are one of the finest free tools available.

    First time I’m knowing about DareBoost and Lipperhey and I am definitely going to try these.

    I would just like to add that SEO Quake is a great tool that combines full-featured SEO analysis at one place and can be run easily via a browser plugin.
    Thanks
    Joyita

  5. Thank you so much for this post, this is a great list of SEO tools that I will definitely use for my future clients and my own site. Can you suggest a good tool to check for keyword density on a page, for short and long tail keywords?

  6. Hey Brian,

    it’s fantastic that Seobility made it on your list!! Thank you so much!!

    We also launched some new stuff in the last weeks, a free SEO Check App on Android and APIs to connect Seobility with other systems or to build your own site auditor.
    Also I’m excited what you think about our TF-IDF Content Creation Tool.

    Thanks again!

    Tom

  7. Hi,
    I love the dashboard features of Siteliner and Lipperhey but am looking for a tool that as well as checking for broken links, duplicate content etc also incorporates website submissions to search engines. We currently use SEOprofiler but dont use many of the features we are paying for so am looking for something cheaper or free if possible?

  8. Great post Brian – I’m trying to find a cheap/free rank tracker that will just give me a couple of hundred keywords, something no-frills is fine. I’ll check out some of the suggestions here – cheers!

  9. Hi,

  10. Hey Brian, big fan of your content.
    Have you tried using Google’s Lighthouse browser extension?
    It gives you a full 360 view of a lot of ranking factors like SEO and site speed.
    Thanks for all your work!

    1. Thanks Jordan. I’ve only used Google’s lighthouse stuff in the Google Pagespeed insights tool. I’ll have to give the browser extension a try!

      1. You need to be careful with Lighthouse Chrome extension. For measuring performance in “throttling mode” your computer power and use part of it. This means that for performance check for some specific site you will receive a completely different result.
        Another issue – you know, it’s an extension … and probably not the only one installed in your Chrome. Each of those installed extensions may have an impact on performance result, because of javascript injection.
        The results returned from pagespeed insights or web.dev are much more reliable than from extension (even if they return different values).

  11. I can’t imagine my day-to-day work without some of them, but I’d all add Nightwach Search Simulator to this list. It simulates unbiased search queries from anywhere. Super useful to track your competitors’ rankings too.

  12. Hi Brian

    Great Article, awesome list of tools and website.
    I personally loved the Rank Checker tool you mentioned, until now I was using Bright Local but they didnot have any Bulk feature like seoreviewtools

  13. I’m not sure how you can call half of these free when all the free version gives you for example is like the first 5 keywords that would have been exactly the same in Google’s own Keyword Tool.

    I’m not questioning that there are some great tools here, but a lot of them need to be paid for before they actually become usable.

    1. Fair enough, Doug. There really aren’t 25 completely free tools that I’d recommend. These all contain free versions which may or may not meet your needs.

  14. Hi Brian,

    As usual a great informative post!
    However, I could not see a free tool dedicated to backlinks here. I believe openlinkprofiler.org would be a good fit.

    Regards

  15. Hi Brian,
    I loved this blog. I used some of the sites from this list but I didn’t listen the name of some of sites at all. Thanks for this informative article. I will check all of these sites.

  16. KWFinder is definitely not a free seo tool anymore. They’ve even restricted their free access which they were providing earlier. So, that needs to be updated.

    Apart from that, I loved the list! It will come in handy!

    1. Not that I know of. It’s something no tool (outside of Google) can really measure because there are hundreds of variables.

  17. Nice, quite a few that I have never even tried.

    My trustworthy duo is Yoast and Ubersuggest, I wholeheartedly recommend everyone to try em.

    Thanks for the list and greetings from Finland 👍

    1. You think so ? I tried to use UberSuggest for search a really basic keyword and it couldn’t find any information at all for a widely used keyword..

  18. Great article on this I find Yoast to be effective on sever of the sites I work on. And Uber Suggest for sure is one of the most valuable tools when looking for a free SEO tool its incredible as a free tool.

    I currently have hrefs, SEM Rush paid but I still compare results on Uber suggest and search what trending on Google Trends constantly.

  19. Hi Brian, thanks a lot for the great post ! Out of the 25, which ones are you using the most ? What would be a good a complete combo to start with ? I am now focusing on sharing content to capture leads.

    1. I had the same issue. I invested time to go to the website of each of these tools, had to read through the specs of what they offer in their free account etc etc. Some of them did not even allow you to use one single feature until you gave them details for a credit card (even thouhg they wouldn’t charge it for 10-15 days or so). I did not enjoy this approch at all. Free is free. “Free version” should only talk about what you can do in the free version. Same goes for trial version.

  20. Hey Brian great post.

    Do you know of any onsite optimization tools that looks at your onpage seo vs your competition.

    For example a snapshot of the top 10 serps compared to the webpage webpage you’re trying to rank.

    1. Thanks Stanford. I don’t know a tool that does exactly that. The closest thing to what you described would be a tool called canirank.com.

  21. Hi Brian, thank you for your reviews on these seo tools. Unfortunately for the 2nd tool you suggest it is only free for 14 days, which is disappointing. I haven’t finished the whole list yet but is this the same theme for most of them?

  22. Thanks Brian!
    I love these tools & always share them with colleagues & clients.

    It is great that most tools have the ability to utilize Google.

    Is it likely that Google India mobile will be in a future roadmap for the keyword research & keyword rank checker?
