free seo toolsWhenever I dream up a home improvement project for my place, I end up working smartest and fastest when I have the right tools at my disposal. It’s amazing the difference a good tool can make – and the extra time it takes to get work done without a helpful tool.

Fast-forward to online marketing. How can you work smarter and faster with SEO? 

It starts with having the right tools.

I’ve collected a big sampling of the best free SEO tools on the market—tools with a wide variety of uses and covering a number of common needs. These tools are fast, free, and easy-to-use. I hope you find one or two (or twenty) you can put to good use, today.

24 Free and Easy SEO Tools

1. Google PageSpeed Insights

Check the speed and usability of your site on multiple devices

Enter a URL, and this tool will test the loading time and performance for desktop and for mobile, plus identify opportunities to improve (and pat you on the back for what you’re doing well). The mobile results also come with a user experience score, grading areas like tap targets and font sizes.

 Alternatives: Pingdom, WebPageTest, and GTmetrix

2. Moz Local Listing Score

See how your local business looks online

Moz crunches data from more than 15 different sources—including Google, Foursquare, and Facebook—to score your brick-and-mortar business on how it looks online. Results come complete with actionable fixes for inconsistent or incomplete listings.

local listing score


700+ keyword ideas based on a single keyword

Enter a keyword, and the Keyword Tool provides a huge handful of long-tail keyword opportunities, organized alphabetically.

Alternative: Übersuggest

4. Google Analytics

Complete web stats and search insights

In addition to tracking pretty much every bit of traffic you could imagine on your website, Analytics also surfaces many keyword insights as to which terms people use to land on your pages.


Alternative: Piwik

5. Google Webmaster Tools + Bing Webmaster Tools

Constant website analysis, alerts, and error reports

These webmaster tools help give you a taste of what the two top search engines think of your site. It’s helpful to see any bugs, alerts, and indexing issues.

Pro tip: Each of these two tools requires a bit of installation on your site. If you’ve got a WordPress website, you can add the webmaster code automatically through a plugin like Jetpack or Yoast.

6. Open Site Explorer

Comprehensive link analysis

The free version of Open Site Explorer gives you a quick look a full range of link analysis, including a look at the most impactful links coming your way and your most linked-to pages.

7. Google Keyword Planner

Know what people search for

Enter a keyword or group of keywords into the tool, and Google will return all sorts of helpful stats to guide your keyword strategy: monthly search volume, competition, and even suggested terms you might not have considered.

8. in an Incognito Window

Discover auto-fill opportunities

Searching in an incognito window will bring up that all-familiar list of autofill options, many of which can help guide your keyword research. The incognito ensures that any customized search data Google stores when you’re signed in gets left out. Incognito may also be helpful to see where you truly rank on a results page for a certain term.

9. Google Trends

Changes in search volume for key terms

A quick browse or search through Google Trends can show you the hockey-stick rise of potential terms and SEO opportunities for your content.

10. QuickSprout Website Analyzer

Full analysis of your website

The QuickSprout tool does a comprehensive look at just about everything: SEO optimization, speed, tags, keywords, social, links, and even competitor comparisons.

11. Schema Creator

Uber-customize the way your search results appear

Create custom code so that your reviews, events, organizations, and people are displayed the way you want on search pages. Once you’ve created your schema code, copy and paste to your website, or try the free WordPress plugin for an even easier implementation.

Here’s an example of schema in action:


12. SimilarWeb

View site stats for any domain

Use this tool to compare traffic between two websites, a helpful tool for competitor research.


13. SERPs Rank Checker

See where your site ranks for certain terms

You can run Rank Checker one of two ways: Input your keyword and your website and see where you land, or leave the website field blank to view the top-to-bottom list of results for a keyword.

14. XML Sitemaps

Build a sitemap

Simply enter your site’s URL and some optional parameters, and XML Sitemaps will create a sitemap that you can upload to Google Webmaster Tools.

15. Browseo

See your website the way a search engine sees it

Enter your site, and this tool will strip out everything but the guts, revealing your website the way search spiders see it. This particular view can be helpful to see the hierarchy you’ve given particular elements (maybe without realizing it!).


16. SEO Site Checkup

Audit and score for your website

Site Checkup runs through a fast audit of your site, checking for proper tags and surfacing any errors that might come up.

17. Searchmetrics Website Analyzer

Performance dashboard for search and social rankings 

The free version of the Searchmetrics report shows you a taste of how your website ranks in search and social, along with a preview of top terms.

18. Find Broken Links

Discover errors on your site

The link report from Ninja Internet Marketers combs through your whole site and highlights a number of link insights, including the internal and external links that need fixing.

broken links errors

19. Ahrefs’ Site Explorer and Backlink Checker

Complete overview of your website, pages, and links

A free (and substantial) sampling of what ahrefs offers, the dashboards for referring pages and inbound links are rich and informative.


20. Copyscape

Check for duplicate content

Enter a URL for a blogpost or website, and Copyscape can tell you where else that content exists online. You might find results that you’ll need to follow-up with to help get your SEO in order.

21. Moz toolbar

I’ve shied away from referencing any toolbars thus far, but the Moz toolbar is just too good to pass up. Once installed, the Moz toolbar can show you SEO insights from within Google search results pages and at any particular website.


22. Robots.txt Generator

Robots.txt files let the web robots know what to do with a website’s pages. When a page is disallowed in robots.txt, that’s instructions telling the robots to completely skip over those web pages. There are some exceptions in which case a robots.txt might be ignored, most notably malware robots that are looking for security issues.

23. Structured Data Testing Tool

Structured data helps to provide context to the information on your page. This tool from Google uses live data to validate the structured data for any web page, or you can copy/paste code to test it.

24. Microsoft Free SEO Toolkit

The Microsoft SEO Toolkit combines quite a few different tools into one. Used together, it can analyze your site and provide recommendations on how to make your site’s content more SEO-friendly, including tweaks to your sitemap and robots.txt. Sorry to all of the Apple folks, this one seems to be Windows-only!

  • Rick Miles

    Kevan – top list of resources, lots of which I use in my day to day SEO work, and including a couple I was unfamiliar with. Good job!

    • Kevan

      Thanks, Rick! Really glad this list fit with your day-to-day SEO. Any tools you use regularly that weren’t on the list? 🙂

      • Rick Miles

        I think you got down most of the free tools for sure. There’s plenty of folks in this industry who only use one SEO tool and I always think they’re missing a trick. Everything has its strengths and weaknesses.

  • Courtney

    I’m new to social media marketing and SEO so this is a great resource list! Thanks for the helpful information.

    • Kevan

      Awesome, Courtney! Thanks for the comment! Hope I steered you in the direction of some good tools. I’d love to hear which ones stick for you!

  • Tony

    Unbelievably detailed post. Very insightful.

    • Kevan

      Thanks, Tony! Awesome to hear from you! Glad you found this post useful!

  • Dev

    Comprehensive as always, Kevan.

  • Diana Wolff

    Thanks for these tips – I tried Copyscape and found a blog post of mine on another agency’s LinkedIn page within five seconds of reading this article. Great value!

    • Kevan

      Really glad this one had an immediate benefit for you, Diana! Hope all is well and good!

  • Frank

    Thanks for great tools and tips. I’m new at social savvy and this is like a swift education. And your blog is a great design. What program or service is it?

    • Kevan

      Hi Frank! We use WordPress for the blog, and it’s a custom theme designed by the team here at Buffer. 🙂 How about you?

  • Conrad O’Connell

    I looked at the SEO Site Checkup tool – and closed the tab after it suggested I add meta keywords tags. Buyer beware on that one 😉

    • Kevan

      Thanks for vetting that one, Conrad! Seems like when I ran it the results were quite comprehensive. It might be helpful to know which areas to focus on and which ones (meta keyword tags?) to put on the backburner. 🙂


    Like the idea of similarweb – it is a great way to get a handle on competitor analysis and see what’s working for others in your niche.

  • Christian Karasiewicz

    Great collection of tools. Looking forward to trying out some of the tools I didn’t know about from the list. Thanks for putting together such as detailed post, @kevanlee:disqus!

    • Kevan

      Thanks, Christian! I’d love to hear if you end up using any tools in particular!

      • Christian Karasiewicz

        @kevanlee:disqus, I use Google Analytics, Google Webmaster Tools, and Moz Toolbar. They work great!

        Looking forward to trying out some of the others that are listed.

    how do you fix the pictures that can be compressed or lossless pictures.
    I am currently on the google developer page and also looked online to see if I can find a video of how to do so but can’t find a thing.

    Also is there a way how I can know what pictures need to be fixed, because what I see here needs to be fixed but can’t click each to see what needs to be fixed.

    Help if anyone been in this same situation

    Moz toolbar is just great seo tool I have ever use.

  • Sam Fisher

    Thanks for your tools are not only free, but awesome. Except I use instead of because its “question only tab” mode, so you can generate titles for your text. Keywordtool is still useful because of its youtube functionality.
    As for ahrefs, free version lacks exporting functionality and that’s an issue.
