The 10 VERY Best Free SEO Tools

If you want a complete list of free SEO tools, please keep scrolling.

But:

If you want to know which are the best free SEO tools, pay attention.

1. Claude for SEO

Claude is arguably the best Free AI tool for SEO right now.

Why?

Because you can use its powerful AI models to improve almost every aspect of your SEO. I’ve tested against other popular AI models and Claude is by far the best.

It has a significantly larger context window (200,000 tokens vs ChatGPT’s 32,000 tokens) which allows it to analyse larger amounts of text and provide more specialised recommendations for SEO.

And the free version will be enough for most users.

Here’s how to use Claude for SEO:

Start by copying your content into a new Claude Chat. Make sure you have the 3.5 Sonnet on.

Explain to Claude what your content is about and provide the target keyword.

Then, ask Claude to:

Claude will then give you a full breakdown of your content and where it can be improved.

This is the first part of the output that Claude gave me:

Pretty good, right?

Implementing the practical analysis from Claude will already improve your content’s standard. But we are just getting started…

Next, you can get Claude to do a lot of the heavy lifting for content enhancements. 

Use these types of prompts-

You get the point! You can essentially start tackling key SEO issues Claude identified to enhance the content.

Remember that Claude is not 100% right all the time, so don’t just follow what it’s saying blindly. Use your own judgment to make good decisions.

Made all the changes? The last step is to do a final review…

Re-upload the content into the Claude chat and ask the AI to:

Make any final adjustments before uploading the new content to your site.

Claude isn’t just a writing tool – it’s like having an SEO expert review your content in real time.

2. The Backlink Blacklist

Last updated in January 2025, the free backlink blacklist is a database of known public blog networks, guest post farms & links sold via cold outreach or marketplaces like Fiverr.

So far, there are over 60,000 domains on the blacklist that you absolutely do not want a link from:

You can see precisely why a domain is on the backlink blacklist.

And you can click on that reason to see a screenshot of the evidence:

On top of that, you can also export the reports into a handy CSV file making this one of the best free SEO tools available right now. This is a no-brainer to ensure you only have quality backlinks.

3. Quick Win SEO Strategy Builder

What’s more?

It doesn’t get much that, right?

Learn how to push this free version to its limits in my full Ahrefs Webmaster tools review.

5. Google Search Console

Google Search Console is a tool that every SEO should have as part of their arsenal.

You can manage a lot of the back of house for your site and find problems that are holding back your search progress.

For example, you can use the Crawl Errors tool to find problems:

And you can even monitor your Core Web Vitals, which means you can track all of your page experience signals in one place.

This means you essentially look at your website performance through the eyes of Google. GSC lists all the issues it finds, so you know what needs fixing.

But that’s not all…

Google Search Console gives you access to a full breakdown of your backlink profile that is just as useful as some of the data you get with expensive tools:

It is also perfect for managing actions taken against your site, especially if you’ve been penalised for webspam or malware at any point in the past.

And don’t forget the most powerful feature of all!

Search Analytics.

That will allow you to see how your site is performing in Google right now.

You can track the total number of impressions your pages have in the SERPS along with the average ranking position and click-through rate data.

You can also find a list of keywords and you can filter by page to find out exactly which page is ranking for which keywords.

This is one of the most powerful hidden features of Google Search Console which makes it one of the best free SEO tools by far.

6. Rank Math

Rank Math is an SEO plugin for WordPress that helps people optimize their content with built-in suggestions based on widely-accepted best practices.

It has a clean and simple interface:

Rank Math allows you to:

RankMath has also released its own AI Content assistant.

How does it work?

You simply type a double slash (//) and prompt the AI assistant inside the WordPress editor. It immediately starts writing content for you, using the surrounding content as the context of what to write.

The free version gives you limited AI credits, and the output quality isn’t great. You’ll definitely need to edit the content heavily if you choose to use it.

RankMath also integrates with platforms like-

And the best part is, it’s 100% free! Personally, I think it’s the best SEO plugin for WordPress. Read my full RankMath review to find out why.

7. Keyword Surfer Extension

Keyword Surfer is a 100% free Chrome extension that allows you to generate keyword ideas and see search volumes directly in Google’s search results.

Just install the extension, and that’s all there is to it.

Now when you search in Google, you’ll get valuable like:

You can find search volume and similar keywords in 70 countries.

Keyword Surfer also integrates with ChatGPT, allowing you to humanise AI-generated content with just one click.
After installing the extension, you’ll see the Surfer widget inside ChatGPT.

Once you’ve generated content, click the humanise button. Surfer AI will immediately rewrite the content to sound more human.

It even gives you a percentage score of how likely your content will be detected as human vs AI.

8. Google Analytics 4

Google Analytics 4 shows you everything you need to know about your sites data.

It shows you the real-world results of every action you take on your site. How it impacts your traffic, how it increases your conversions, who it attracts to your site.

And, that’s just the tip of the iceberg.

The main reason I’d suggest you use Google Analytics 4 is so you can track your progress and consistently strive to improve on it.

You can track how much of your traffic comes from different sources and dig even deeper to see where is bringing you the most traffic month on month.

But most importantly you can see which traffic converts:

Now, it can be easy to get caught up in the Vanity Metrics (stuff that looks and sounds good but doesn’t really mean anything) that’s often provided by Google Analytics 4.

That’s why it’s important to use the tool to track results.

Don’t trust Google? Check out my list of Google Analytics alternatives!

9. Screaming Frog

Screaming Frog is one of the most commonly talked about SEO tools on the planet.

This SEO spider based tool’s main objective is to save time on finding SEO problems and completing SEO audits. And, boy, they’ve succeeded in that.

Enter your (or your competitors) site’s URL and it’ll crawl. Once it’s finished you’ll get a complete look at the site, and in-depth information about each page.

It breaks down every known technical and on page SEO Google ranking factor there is. Screaming Frog is also considered as the best site auditing tool you can get.

The free version is limited to 500 URL/s which is fine for most small to medium sites!

10. Google PageSpeed Insights

Your site speed is a huge ranking factor.

The faster your page loads the more likely your site is to rank highly, and have a better user experience to go with it.

Google PageSpeed Insights can help you track it.

Crazy, right?

It then suggests improvements based on the results and Google Search Essentials best practices.

Meaning you can create a much faster, more streamlined site, without negatively changing your search results.

You can fix most of these problems without spending any money by following my tutorial to increase website speed.

Bonus: FAQ Snippet Editor

Last year I released the free FAQ schema generator tool.

If you don’t know why you should be using this, watch this video:

The tool is really easy to use.

All you have to do is fill out the first question & answer and then, click on “+Add another question” to add more. You can add as many as you want (4-6 is perfect).

Just follow the tutorial on this page to deploy the code.

And… don’t forget to check your schema with a schema tester!

AI SEO Tools

Ready to supercharge your SEO with AI?

Below are the best AI-powered SEO tools.

Keep in mind that Claude.ai has already been covered in my top 10 free SEO tools.

Here are the free AI SEO tools that are worth your time.

11. ChatGPT

ChatGPT can be turned into your secret weapon for SEO.

And I am talking way more than just writing generic AI content for a website or blog.

Here’s everything you can do with ChatGPT for SEO:

With that in mind, Let me show you my top three ways to use ChatGPT (plus I’ve included the prompts as well).

All of this can be done on the free ChatGPT plan.

First up is Content Creation Ideas.

If you’re struggling to come up with ideas, plug this prompt into ChatGPT:

“I need content ideas for a blog targeting [industry/niche]. The goal is to rank for the keyword ‘[primary keyword].’ Please provide 10 engaging blog titles with a specific focus on search intent and value to readers.”

Pro tip: Add “including LSI keywords” to the end of the prompt to get content ideas that cover related topics too.

Next up is On-Page SEO Suggestions.

Use this prompt to get ChatGPT to do a thorough on-page SEO audit on your content:

“Review the following webpage content: ‘[paste content].’ Provide detailed and thorough on-page SEO  recommendations, including keyword usage, heading structure, internal linking, and alt tags for images and more.”

​​ChatGPT will analyse your content and give you actionable steps to improve it.

Now, this last one can save you a lot of time in link building…

Personalised Outreach Emails.

Here’s the prompt:

“Create a personalised outreach email template for requesting backlinks. The target website is ‘[example website],’ and the goal is to promote our article titled ‘[article title].’ Crawl the website and personalise the message. Keep the tone professional and persuasive. The email should be short and straight to the point.”

You will need to customise the prompt to fit your business, niche, and target websites. But the output will enable you to do much more personalised link-building outreach.

More personalised = more links.

Who doesn’t want that, right?

The truth is ChatGPT has many powerful SEO applications. It all comes back to your creativity and prompting skills!

Did you know you could easily detect content written by AI tools (such as ChatGPT) with a public AI content-detector tool like Orginiality.ai? Read my full Originality.ai review to learn more.

12. SEO.ai Free Tools

SEO.ai gives you access to 46 AI-powered SEO tools without spending a penny.

It’s a massive collection of SEO tools that will help you with everything from keyword research to content creation.

These are some of my favourites:

The best part is that all the tools are completely free to use, and you don’t need an account to take advantage of them.

It’s one of the best applications for AI that I’ve seen in the SEO software industry so far! Have some fun browsing through all the tools and level up your entire SEO workflow.

13. DeepSeek For SEO

The new DeepSeek R1 model was released recently and is so powerful, it triggered the biggest US stock market loss in history with Nvidia stock losing $589 billion in a day.

Why is DeepSeek a great SEO tool though?

Because quite simply, what ChatGPT can do – DeepSeek can do better (and cheaper):

However we still don’t think it’s as good as Claude for most SEO tasks yet but we are certainly keeping an eye on it.

It’s certainly better than ChatGPT anyway, but so is Claude.

Keyword Research Tools

Keyword research is one of the most important tasks in SEO.

Good keyword selection can bring you organic search traffic and help you grow your business. But bad keyword selection will drain your resources!

Below you’ll find a list of free keyword research tools that can help you find profitable keywords with high search volume.

14. Keyword Research Strategy Builder

Keyword research is hard work, so I built a free tool that helps you to find all of your competitors best keywords.

Then it tells you which of those keywords are the easiest to rank for with the highest search volume – simple!

To see how it works, just watch this tutorial:

Why go to the hard work of creating an SEO strategy when your competitors have already done it for you?

Download my keyword research tool now! It only takes a few minutes to implement and it’s 100% free!

15. Ahrefs Keyword Difficulty Checker

Ahref Keyword Difficulty Checker is a free SEO software that helps you find out the ‘ranking difficulty’ of the keyword you want to rank for.

Just enter your keyword and choose the country you want to rank in.

It gives you a score that fluctuates between 0 and 100.

The higher the number, the harder it is to rank.

Bonus: It also tells you approximately how many backlinks you’ll need to rank in the top 10. You can use these link building strategies or link building services or link building oackages if you need help with that.

But that’s not all. It also gives you a SERP overview for your keyword.

You can do as many searches as you want for free!

My full Ahrefs review shows you a bunch of other cool things you can do.

In my opinion, this is one of the best free SEO software available right now.

16. Answer The Public

Answer The Public is a great tool to find out what problems your target audience faces.

It’s a huge searchable database of questions which you can use to create and fine tune your website content.

The results appear like this:

But I always download the free CSV report that includes:

If you sign up for a free Answer the public account, you get 3 free searches per day, including some historical data.

It’s worth having the free account for whenever you need it!

17. AlsoAsked

AlsoAsked is a freemium keyword research tool.

But if you are looking for some quick keyword ideas, it offers a ton of value on the free plan.

Here’s how it works:

AlsoAsked helps you find the questions and long-tail keywords that people are asking related to your topic or niche.

It leverages Google’s “People Also Ask” boxes in real-time and allows you to filter for specific countries and even languages.

You type in a keyword and AlsoAsked creates a visual representation of questions and sub-questions related to your input.

This will help you-

On the free plan, you’ll get up to 100 searches per month which is enough for most people.

You can also export data in a PNG image to quickly share it with others.

It’s a must-add to your free SEO tool list if you want to improve your keyword research and content!

18. Ubersuggest

Ubersuggest is one of the best free keyword research tools out there.

It has a ton of great features and even includes some extra SEO tools you will benefit from.

Let’s start at the top…

Just type in your target keyword and get access to:

Ubersuggest will give you a full breakdown of that keyword so you know if it’s worth targeting.

Scroll further down the page and get even more keyword ideas related to your initial target keyword.

If the keyword data is outdated, you can update it on demand!

What’s more?

Track up to 25 keywords for your site and monitor 2 competitors to see how you stack up. 

And just in case that’s not enough for free, you’ll even get access to the Ubersuggest site audit tool and backlink monitoring tool.

It’s almost like having a mini Ahrefs in your back pocket!

The free version of the tool allows you to search for up to 3 keywords per day and 200 free credits for other reports – Which is great if you are just getting started. You can also integrate Ubersuggest with Google Search Console to import all that data.

There is seriously so much here that will level-up your SEO game!

19. Keyworddit

Want to find keywords based on what your audience is actually talking about?

That’s where Keywroddit comes in.

It’s a free tool that extracts keywords from any subreddit with more than 10,000 subscribers.

You type in the name of a subreddit, and you’ll get-

You also have the option to export the data as a CSV file and use it later.

Keywroddit is a super simple tool that will uncover unique keywords people are actually using (and your competitors won’t find). That’s a recipe for great content ideas!

20. Keyword.io

Keyword.io let’s you search keywords in a ton of different engines – including Google, Bing, Wikipedia and more.

On their homepage, just select the search engine, root keyword and country you’d like and hit search:

Then you’ll be given hundreds of relevant keywords to choose from almost instantly.

This is great for finding long and short tail keywords that you can sprinkle throughout your site or content.

Keyword.io even supports keyword research for YouTube, Amazon, Fiverr and eBay. It really is a powerful research tool!

21. CanIRank

CanIRank allows you to see how likely your site will rank for a keyword.

It also gives you the steps you need to take to make it happen.

And you’re also able to analyse keywords, your site’s current ability to rank for it and how you stack up against the competition. This includes a difficulty score so you know what you’re up against.

It will also show you relevant keywords to choose from:

And then you can click into any of those to get a closer look at the keywords value:

As well as giving me a complete breakdown of who else ranks for this keyword. Why they rank for it. And, the areas I can focus on to get the upper hand.

The last awesome feature is the content gap analysis. CanIRank gives you a ideas for content based on your site, the competition, traffic and value.

I’d take the results with a pinch of salt, but it can help you find weaknesses in your SEO.

22. Seed Keywords

Seed Keywords is a brilliant take on finding keywords.

Instead of researching the keywords that your audience might use, Seed Keywords allows you to ask them for exactly what they would use..

By creating a scenario for your your audience – buying a jacket, looking for a book, finding a new restaurant – you can find the specific search terms that they’ll be looking for.

Let’s say I wanted to find what people would search for to find new SEO tools, here’s the scenario I would create:

You can then share this scenario with your audience, through social media or your mailing list, to find out what search terms they’d actually use.

While this may not provide you with all of the statistics and search volumes, you can start to get an idea for what keywords show up the most.

And then you can cross-reference it with other tools like Google Keyword Planner to get search volumes.

On Page SEO Tools

Need to keep track of your SEO efforts without spending lots of time and money in doing so?

Don’t worry, because I have you covered with the best free on page SEO tools right here.

But most people don’t realise that Cloudflare offers many free tools that can boost SEO.

The free plan of Cloudflare includes access to their massive content deliver network (CDN) of 330+ server locations worldwide. That means your content gets served from the closest possible location to your visitors.

ShortPixel is my secret weapon for image optimisation.

Images and graphics can take a long time to load on your website because they are big files. That can:

This is where ShortPixel comes in.

ShortPixel automatically:

Short Pixel can reduce the size of images by up to 90%, which can significantly speed up your website load times.

It doesn’t get much easier than that, right?

28. SpeedVitals TTFB Test

SpeedVitals TTFB Test is a free but powerful website speed test tool.

TTFB (Time To First Byte) is a metric that measures when a request for a website is made and when the first byte of response begins to arrive in your browser.

It essentially measures how long it takes for the first piece of the website to load.

Why is this important?

Two words – website speed.

You want your website to load as fast as possible and SpeedVitals TTFB test will show you what to optimise.

Type in your website in the TTFB test.

SpeedVitals then shows you how fast your TTFB is across a range of locations worldwide.

Is your TTFB score low? It’s time to get to work and improve it.

31. ImageRaider

ImageRaider is a reverse image search that finds where your images have been used around the internet.

Basically, that means instead of using words to search for an image, it uses images to search for where they’ve been published in the web.

You just upload the file, or paste in the image URL, hit Search Uploaded Image and it’ll scour the internet to see where your image is being used.

You can then get in touch with them and request that they add a link for using your infographic or image.

And, that’s a request they can’t really say no to!

32. SEO Auto Linker

SEO Auto Linker is a WordPress plugin that takes care of all of your internal link building needs.

Just add your URL, and the keywords you want it to automatically insert links for, and you’re all set:

And, if you want to get clever with it, you can add affiliate links to SEO Auto Linker too.

33. WikiGrabber

WikiGrabber allows you to find those all-important broken Wikipedia Links and Citations that you can capitalise on.

See my Wikipedia link building tutorial if you don’t know what I’m talking about.

The tool also comes with a browser extension:

This is a great tool to use if you are running a broken link building campaign.

35. Qwoted

Qwoted is a free PR tool that acts like a bridge between journalists and experts.

Think of it like a free version of HARO (Help A Reporter Out).

You sign up and become an expert on the platform. You’ll then receive relevant media opportunities related to your business or niche expertise.

Inside the platform, you can respond to any journalist’s questions or queries.

Responses might include a:

Anything the journalist is requesting. If the journalist uses your story or expertise in their article, they’ll likely mention you as the source.

The best part?

You don’t need an Ahrefs subscription to use it! Just grab a free authorisation code and you’re ready to go. The only catch is you’ll need to reconnect every few weeks – but that’s a small price to pay for this much value!

The truth is that I don’t think this plugin get’s the recognition it deserves. You can download the plugin here.

38. SEO Powersuite

Each temperature also gets converted into one of five severity levels:

If it’s a stormy day, then something big happened.

Moz uses enhanced algorithm tracking features that make it one of the most accurate SERP trackers available. It also includes industry specific analysis and correlates historical algorithm changes so you can get a better idea of what Google is doing.

The report is updated every morning (~7:30 am Pacific Time) and is great to pick up on early movements.

This is a tonne of data right at your fingertips, and it’s a nice tool to have around, so I’d recommend sticking it on to your extensions list!

60. MozBar

MozBar is one of the original SEO toolbars. And although the competition is getting bigger and better every day (see above) it’s still worth grabbing.

In Google Searches it gives you instant insights into the page, with a focus on Page and Domain Authority:

When you click on the link analysis tool, you can access every link that makes up their PA and DA for your own personal use:

There is also a tonne of other metrics you can pay attention to as well, like Spam Score. With the latest updates you also have the power to customise MozBar and configure certain metrics that are important to you.

A great addition that works best in conjunction with other toolbars for best results but they are far from being the best backlink checker.

61. Check My Links

Check My Links is a really cool tool that allows you to check all of the links in your content – new and existing – to make sure that they’re valid.

Once installed it will crawl through a particular page and it will find the valid links and highlight them in green:

You’ll see all of the warning links in yellow; and all of the links you need to fix or change, in bright red:

All of this is crawled in just a few seconds, and because it’s visual it makes a great aide to show potential new clients some of the issues with their site. Keep in mind it has been updated for ages, but take advantage of it while can.

NoFollow is a simple tool from IgorWare that highlights all of the No Follow links on a website.

Simply download the extension and you’re ready to go. It’ll start to show you all of the no follow links on any page with a red box around them.

Just like this:

NoFollow also shows sponsored and UGC links in content.

It’s not a tool that’s going to win any awards. But, it can be really helpful in making sure you get the links you want, and aren’t hit by any nasty surprises right in the middle of your campaign.

I also like to use it when auditing links to look any correlations between different types of links and rankings of a specific page.

Google’s Own Tools

Google’s tools are often overlooked by new SEOs. And, I get it – you want the shiny new third party tool that promises the earth.

But, some of the most established SEOs I know use these tools to form the backbone of their campaigns.

These are the top 3 things you should be using it for:

1. Identifying trending keywords in your niche
2. Track trends in your niche before they takeoff
3. Get a ton of ideas for new content

Here’s an example:

Let’s say you run an ecommerce store that sells organic skin care. You want to find trend topics and keywords to create content about.

This is where Google Trends is invaluable!

Simply enter a related keyword and let the tool do its magic. First, it will show you how the keyword/topic is trending.

Don’t forget to use the filters at the top to select the country, region and dates.
