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 2018.

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 –

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 –

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 SEO.

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 you can use to fix issues that you run into.

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

3. Detailed.com

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”.

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

Very cool.

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

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. Keywords Everywhere

Get keyword data from around the web.

Keywords Everywhere has quickly become one of my favorite keyword research tools.

Why?

Because it shows you search volume, keyword competition and CPC info… inside of your browser.

That’s right: you don’t need to login anywhere to get this data. You can see keyword info while you shop on Amazon.com, watch videos on YouTube and check your stats in the Google Search Console.

Keywords Everywhere

Best Feature: Bulk Upload

Want to get data on a massive list of keywords?

Well, you can upload a list of up to 10k keywords…

…and get data on every single one:

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

Helpful for figuring out if your title and description tag are not only SEO-friendly… but designed to get clicks.

11. Ubersuggest

Ubersuggest is simple:

For example: filtering out keywords that use the term “free” or “paid”.

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.

Google Search Console – 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.

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

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.

Google Analytics isn’t really an SEO tool.

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

Why?

You need the data in Google Analytics to see 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 don’t know 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.

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.

Wordtracker scout takes a unique approach to keyword research…

KWFinder

  1. Detailed.com is a goldmine – thanks for the tip there. I love the “Mentions” feature where it shows you who recently linked to your competition. I could spend hours combing through that data. Thanks for another great post, Brian!

    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).

  2. 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.

  3. 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!

  4. 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.

  5. 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

  6. 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?

  7. 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

  8. 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?

  9. 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!
