Want to rank in the search results but not ready to invest in a paid tool just yet? We’ve got you covered.

In this post, we’ll be looking at the best free SEO tools on the market. 

We’ve made sure to pick out a good mix of SEO tools that help with all aspects of search engine optimization and have included both completely free solutions as well as freemium platforms.

1. SEO PowerSuite 

SEO PowerSuite is a free all-in-one SEO software solution (with a premium version also available). Anyone can download it for free and get access to the complete gamut of SEO tools, from keyword research and rank tracking to backlink checking and more.

SEO Powersuite Homepage

Unlike most SEO tools, SEO PowerSuite is downloadable. You access it through your desktop rather than your browser, but some of its features like the backlink checker run in the cloud.

Pros and cons

2. Hunter.io

Hunter.io is a simple but very useful outreach tool. It lets you find the email addresses behind any website in seconds, which you can then use in your link-building campaigns.

hunter Homepage

One of the most important parts of SEO is acquiring backlinks, which help you to boost your authority and ranking power. And one of the most effective ways to build backlinks is through blogger outreach.

The idea is to reach out to other website owners in your niche in order to boost your exposure. This might mean asking if you can contribute a free guest post in exchange for a link, or asking them to share your content with their audience.

But to do that, you need to have contact details. And on many websites, contact details are hard to find. 

Hunter.io solves that problem by searching the web to find a list of people working in the company behind the website, along with their email addresses. Once you have that information, you’ll know who to reach out to.

Pros and cons

Easy to useLimited use cases
Find email addresses behind websites
Great for SEO outreach campaigns and link building


The free version of Hunter is limited to 25 monthly searches. Paid plans with higher usage limits and premium features start from $49/month.

Pros and cons

Screaming Frog SEO Spider is free but it’s limited to 500 URLs. If you need to crawl more than that, or you want to access premium features, you can upgrade for £149.00 per year.

5. Answer The Public

Answer The Public is a search listening tool for SEO and content research. You can use it to find topics that your target audience is asking about and discover new question-related keywords.

AnswerThePublic Homepage

It’s essentially a keyword research tool with a cool interface. All you have to do is type in a topic (or seed keyword) related to your business (e.g. ‘chocolate’). Then, Answer The Public will listen in to autocomplete data from search engines around the web to crank out a ton of related keywords.

It sorts these keyword ideas into different sentence types (i.e. ‘what’ questions, ‘why’ questions’, comparative vs phrases, etc.). Because so many of the suggestions are question-related search terms, it’s great for compiling ideas for long-string keywords to include in your FAQ sections.

Pros and cons

You can use Clicky for free on 1 website for up to 3,000 daily page views. Paid plans with premium access are available.

9. Google Keyword Planner

Google Keyword Planner is the original keyword research tool. You can use it to find and analyze keywords to inform both your SEO and PPC campaigns.

Keyword Planner Homepage

Unlike many other keyword research platforms, Google Keyword Planner is completely free. It also provides fairly accurate data and is where most other platforms pull their own data from.

It’s great for getting a rough idea of search volumes and finding keyword ideas, but the interface is a little clunky and built for PPC advertisers, rather than SEOs.

Pros and cons

Accurate and reliable keyword dataBuilt primarily for PPC campaigns (not SEO)
Powered by GoogleMonthly search volume ranges (not exact figures)
Find tons of keyword ideas in minutes
Completely free


Google Keyword Planner is 100% free.

10. Google Search Console

Google Search Console (GSC) is a free website analytics tool powered by Google. It provides you with information on your website visitors and performance in the Google SERPs, as well as other important data.

Google Search Console Homepage

You can use GSC to see which keywords are driving the most visits, and which pages those visitors are landing on. You can then use this information to guide your SEO strategy.

Aside from basic analytics, GSC can also be used to submit your sitemaps (for faster indexing) and check your Core Web Vitals (an important SEO metric pertaining to the user experience).

Pros and cons

Completely freeBasic keyword ranking data only
Easy to useNot possible to distinguish where you are ranking by location
Submit sitemaps
Track search rankings, traffic and Core Web Vitals


Google Search Console is a free tool.

11. Ubersuggest

Ubersuggest Homepage

It’s super simple to use. Just enter a seed keyword to generate a list of related terms and analyze them, or enter a competitor’s domain to reverse engineer their SEO and content marketing strategy.

Google Analytics Homepage

You can use Google Analytics to track site visitors in real-time, see what actions visitors take on your website, and uncover a ton of other useful insights. It’s completely free and an essential tool for all website owners.

Pros and cons

Detailed analyticsMight be overkill for users that only need basic analytics
Behavior flow reportsIncredibly complex for beginners

Google Analytics is a free SEO tool. However, there is a premium version for enterprise customers. You’ll need to request pricing for that.

13. SEOPress

SEOPress is another awesome WordPress SEO plugin. Like Rank Math, it’s an all-in-one tool that can help with all aspects of your SEO campaigns.

SEOPress Homepage

Powered by Google
Completely free


Google Data Studio is free.

16. Measure

Measure is a developer tool powered by PageSpeed Insights. It lets you test and measure your page quality and provides recommendations on how to improve.

Measure Homepage

While Measure is powered by PageSpeed Insights, it’s not exactly the same. Unlike PSI, Measure isn’t performance-focused. It checks the overall quality of the web page and provides insights including performance, accessibility, and SEO. 

It’s a great way to measure and optimize your site pages for a broader range of SEO quality signals. 

Pros and cons

Measure your page qualityDeveloper-heavy (hard to understand for beginners)
Provides custom recommendations
Deeper analysis than PageSpeed Insights


It’s completely free to run an audit with Measure.

17. Google Trends

Google Trends is a fantastic complimentary keyword research tool to use in addition to Google Keyword Planner. It helps you find trending search terms around the world.

Google Trends Homepage

Unlike Google Keywords Planner, Google Trends won’t tell you the average monthly search volume of a keyword. Instead, it tells you how search interest for that keyword has changed over time. It also generates a list of related trending topics or queries that can inform your SEO strategy.

To use Google Trends, start by typing a keyword into the search bar. Next, select the time period region you want to draw data from. If you’re running a local SEO campaign, choose the country you’re interested in ranking in. If you’re targeting a global market, just choose worldwide.

You’ll then see a graph showing search interest for that keyword over time. If the line is trending upward, it’s potentially a sign that the monthly search volume is going to increase over the next year or vice versa.

Below that graph, you’ll see a list of related topics and queries. You can use this to find new keyword ideas to use in your SEO campaigns.

Pros and cons

Great for finding trending content topics in different geographical regionsDoesn’t show search volume or competition
Validate keywords based on search interest trends
Discover new keyword ideas
Compare two search terms side-by-side


Google Trends is a free tool.

18. MozBar

MozBar is a free SEO toolbar and Google Chrome extension. It’s super popular with over 800,000 installations and is the best way to check Domain Authority (DA) and Page Authority (PA) in your browser.

MozBar Homepage

Website authority is an important ranking factor. The more authoritative search engines like Google think a website is, the better chance it stands of ranking in the SERPs.

As a result, high-authority sites are super hard to outrank. When you’re putting together your SEO strategy and trying to figure out which keywords are worth targeting, it helps to know how much authority the sites already ranking for those keywords have.

That’s where MozBar comes in. 

All you have to do is add it to your browser (for free) and it’ll show you the DA and PA of any domain while you browse the internet. Moz calculates DA and PA based on various factors, mostly related to the number and quality of backlinks the domain or page has. 

If you see a bunch of 80-90+ DA sites ranking on page one of the SERPs, you know it’s probably a difficult keyword to rank for. If you see a bunch of 10-20+ DA sites, you know it’s probably low competition.

Aside from DA and PA, you also get access to a bunch of other metrics while viewing any website page or SERP. You can view the page’s spam score, the number of backlinks, referring domains, etc. at a glance or open up a Link Analysis to take a closer look.

Pros and cons

View DA/PA and link metrics in the SERPsCan be buggy/glitchy sometimes
Analyze any domain in one click
Useful for keyword research and link building


You can download and use MozBar for free. 

If you want to unlock additional features and more metrics, you can upgrade to MozBar Premium for $179 per month.

19. Yoast SEO

Yoast SEO is one of the most popular free WordPress SEO plugins on the market. Add it to your WP site to optimize your site and content for search.

Yoast SEO Homepage

Yoast offers an incredibly generous free plan. Anyone can install and activate it without spending a penny and get access to a suite of powerful SEO tools.

It will take care of all the most critical technical SEO tasks for you. You can use it to submit XML sitemaps to Google (to help with indexing), automatically manage redirects to avoid 404 errors, customize titles and meta descriptions, etc.

But where Yoast really shines is its content optimization feature. The built-in content checker makes it easy to make sure your content is optimized for search before you hit publish.

That said, I would recommend a dedicated content optimization tool like Surfer or Frase being used in addition to Yoast.

Underneath the WordPress editor, you’ll see the Yoast content checker toolbar. It uses a simple traffic light system to score content and provides a checklist of what you’ve done well, and what you still need to improve. 

All you have to do is turn red items green to boost your chances of ranking well in the SERPs. When your overall score is good, you can publish with confidence.

Pros and cons

Powerful content checker toolFree version limited to one target keyword
Full-featured SEO pluginHas slowly moved free features into their premium version over the years
Takes care of the backend, technical tasksWordPress only
Generous free plan


You can use the basic version of Yoast SEO for free. 

To unlock the full power of the plugin, you can upgrade to Yoast SEO Premium for $99 per year.

20. Keyword Surfer

Keyword Surfer is a keyword research chrome extension by Surfer SEO. It’s one of the only free chrome extensions that provides estimated monthly search volumes as you browse the internet.

Keyword Surfer Homepage

Let me know if this sounds familiar: You’re working on your SEO strategy and researching potential keywords to target. You’re using Google search suggestions to brainstorm ideas and when you find one that has potential, you note it down. 

Then, you open up Google Keywords Planner (GKP) or another keyword research tool and paste it in to find out its average monthly search volume so you know whether or not it’s worth targeting.

There are a lot of steps in that process, don’t you think? Wouldn’t it be easier if you could see the search volume right there in Google as soon as the suggestion pops up? That way, you can instantly validate its potential without having to open up GKP first.

Well, that’s where Keyword Surfer comes in handy. All you have to do is install it in your Chrome browser. Then, whenever you search for a keyword in Google (or on any other search engine), it’ll display the search volume and the CPC right there in the search bar.

And that’s not all. It’ll also display other useful metrics below the pages ranking in Google for that search term, including the domain’s monthly traffic and the number of words on the page, which can help you to analyze the competition. Keyword Surfer is the only extension we’ve seen that offers all of this for free.

Pros and cons

Easy keyword researchOccasional bugs
Time-saving benefits
Competitor analysis
Provides CPC, search volume, and more in your browser


Keyword Surfer is 100% free. Plans start from $89/month with annual discounts available. Try with a 7-day free trial of their features.

21. All In One Schema Rich Snippets

All In One Schema Rich Snippets is a free WordPress plugin that makes it easy to implement schema markup.

All In One Schema Rich Snippets Homepage

Schema markup is a structured data vocabulary that you can use to give search engines more information about your website pages and improve your visibility in the SERPs.

Once you add schema to your pages, Google can use it to serve up rich results. Rich results (rich snippets) are short summaries of your page that appear in the search results. They provide more information to searchers than regular results and often have eye-catching, interactive elements (like star ratings and FAQ lists). 

Having your website pages appear alongside rich results in the SERPs has also been shown to improve click-through rates (CTR), which makes schema an important SEO strategy.

The only problem is that adding schema is a technical process that involves messing around with HTML code. As such, non-tech-savvy bloggers and small website owners may feel it’s out of their reach.

Fortunately, All In One Schema Rich Snippets makes it easy. Instead of editing your code, you can just install and activate the plugin and let it take care of everything for you.

Pros and cons

Easy schema markupUse old MicroData that affects front-end design (Schema data is visible on the website)
Improve SERP visibility


All In One Schema Rich Snippets is a free plugin. However, it uses MicroData, so it affects the front-end design of your site. 

Schema Pro is a premium alternative that costs $79 per year. It uses JSON-LD technology and won’t affect your site design.

22. PageSpeed Insights

PageSpeed Insights is a developer tool by Google. It enables website owners to analyze the performance and Core Web Vitals of a web page and then offers suggestions on how to improve.

PageSpeed Insights Homepage

Ever since Google’s Page Experience update, user experience has become very important from an SEO perspective. Google’s algorithm now places a lot more importance on ‘Core Web Vitals’ — a set of metrics/ranking factors that measures the user experience.

Core Web Vitals are made up of three different metrics:  largest contentful paint, first input delay, and cumulative layout shift. These roughly correlate to loading speed, interactivity, and visual stability.

PageSpeed Insights (PSI) analyzes your website and tells you how you’re performing in these three metrics. All you have to do is enter your website URL in the bar and click Analyze.

Based on your performance, you’ll be given a ‘passed’ or ‘failed’ assessment so you know whether or not you need to take action urgently.

At the bottom of the page, you’ll see a deeper diagnostics analysis and a list of ‘opportunities’, which tell you what you can do to improve your score.

Pros and cons

Analyzes Core Web VitalsSuggestions can be difficult to understand for non-developers
Provides suggestions on how to boost performance
Measures three metrics
Deep diagnostics


PageSpeed Insights is completely free.

23. Smush

Smush is a free image optimization plugin for WordPress. It can help you boost your site speed (and with it, your SEO) by compressing and resizing your images.

Smush Homepage

We’ve already talked about how site speed is an important SEO ranking factor. But did you know that the images you use in your website posts and pages have a huge effect on speeds?

Large, bulky images can take a long time to load when your visitors open your website. This not only harms the user experience but also increases your average page loading speeds, which sends the wrong kind of signal to Google and can hurt your organic ranking position.

The solution: Smush. It’s one of our all-time favorite WordPress plugins and a must-have for any blogger or website owner concerned about SEO. 

It’s super simple to set up and can have a dramatic impact on your search performance. All you have to do is install and activate it on your WP site, then configure the settings for automatic image optimization.

Smush uses lossless compression to reduce the file size of all the images you use without reducing the quality. You can bulk optimize and compress all the existing images that are slowing down your site with one click, and use the built-in automation to automatically compress new images as soon as you upload them to your media library.

And if that wasn’t enough, Smush also offers a neat feature called ‘lazy loading’. Once you enable lazy loading, Smush will defer offscreen images so that they don’t load for your visitors until they’re visible on the screen (i.e. when they scroll down the page). This reduces initial page loading times for further speed gains.

Pros and cons

Optimize images to improve speedsIntrusive advertisements unless you upgrade
Lazy load feature
Automatic compression and optimization
Bulk image optimization


The regular version of Smush is completely free. You can upgrade to Smush Pro for $5/month to unlock premium features.

Final thoughts

As you can see, there are plenty of free SEO tools out there. You probably don’t have time to try them all out, so here’s a recap of our favorite:

  • SEO PowerSuite is a free downloadable all-in-one SEO software solution. It comes with everything you need for your SEO marketing campaigns, including a powerful keyword research tool, local and global rank tracking, site auditing, backlink research, etc. While you can’t save projects in the free version, the functionality you get access to is extremely good.
