The 30 Best Free SEO Tools
We understand the value of top-end SEO tools — we've designed and built best-in-class search tools for close to 5 years. Premium tools are hugely valuable in SEO when you need higher limits, advanced functionality, stored data, or on-call support. But for 75 percent of other tasks, a free tool often does the trick. There are literally hundreds of free SEO tools out there, so we want to focus on only the best and most useful to add to your toolbox.
The Best Free SEO Tools
1. Bing Webmaster Tools
While Google Webmaster Tools gets all the glory, folks forget that Bing Webmaster offers a full suite of website and search analytics. Especially useful are keyword reports, keyword research, and crawling data.
2. Google Analytics
The big kahuna, and the most widely-used web analytics package on earth. For being free, Google Analytics is surprisingly robust and plays well with other Google products, including Optimize, Search Console, and Data Studio. Some folks have privacy concerns with GA — though Google swears they don't use this data for search rankings.
3. Search Console
Probably the most useful free SEO tool on this entire list, it's hard to imagine doing modern SEO without access to the data inside Google's Search Console. This is the most reliable location for information on how Google crawls and ranks your site, and is one of the only places where you can get reliable keyword data.
4. Keyword Heros
Did somebody say (not provided)? Keyword Hero works to solve the problem of missing keyword data with lots of advanced math and machine learning. It's not a perfect system, but for those struggling to match keywords with conversion and other on-site metrics, the data can be a valuable step in the right direction. Pricing is free up to 2000 sessions/month.
5. Redirect Path
Similar to Link Redirect Trace, Redirect Path is a nifty tool from the good folks at Ayima that shows redirect paths and header information for every URL you visit. Gotta admit, I've used this extension for years and it's almost "always on" in my browser.
6. Screaming Frog
Aside from having one of the best Twitter accounts of any SEO tool maker, Screaming Frog is the most popular desktop-based crawler available today. Many people don't realize that there's a free version that allows for up to 500 URLs per crawl. While not as fully functional as the paid version, it's great for small projects and smaller site audits.
SEOlyzer is a log analysis tool recommended by Aleyda Solis in her very excellent SEO podcast Crawling Mondays. SEOlyzer is a terrific log analysis tool with some cool features like real-time analysis and page categorization.
8. Answer The Public
It's hard not to love Answer The Public. The interface has an almost "Cards Against Humanity" rebel vibe to it. Regardless, if you want to generate a massive list of questions from any keyword set, this is your go-to tool.
9. Keyword Explorer
If you're not familiar with Moz's amazing keyword research tool, you should give it a try. 500 million keyword suggestions, all the most accurate volume ranges in the industry. You also get Moz's famous Keyword Difficulty Score along with CTR data. Moz's free community account gives you access to 10 queries a month, with each query literally giving you up to 1000 keyword suggestions along with SERP analysis.
10. Keyword Planner
Google's own Keyword Planner was built for folks who buy Google ads, but it still delivers a ton of information useful for SEO keyword planning. It uses Google's own data and has useful functions like country filtering. Be careful with metrics like competition (this is meant for paid placements) and volume — which is known to be confusing.
11. Keyword Surfer
We used to recommend Keywords Everywhere (still a great tool) but they no longer offer a free version. As an alternative, the most popular community-based recommendation—that's still free—is Keyword Surfer. This Chrome extension gives you keyword search volume in Google search results. We're also a fan of WMS Everywhere, a Chrome extension that gives you search volume, cost-per-click, and keyword suggestions.
Neil took over Ubersuggest not long ago and gave it a major overall. If you haven't tried it in a while, it now goes way beyond keyword suggestions and offers a lot of extended SEO capabilities such as basic link metrics and top competitor pages.
13. Link Explorer
Link Explorer is arguably the largest, highest-accuracy link index and the most accurate DA and backlink checker in the SEO world today, boasting 35 trillion links. The free account access gives you 10 queries and 50 rows of data per query every month, plus adds basic link metrics to the MozBar as you browse the web.
14. Link Miner
Link Miner is a free Chrome extension developed by Jon Cooper, one of the masters of link building. Use it to quickly find broken links on each page, as well as see basic link metrics as you search Google. Simple, easy, and useful.
15. Backlink Checker
Many people don't realize that Ahrefs offers a free backlink checker, but they do, and it's pretty good. It does have a number limitations compared to their full-fledged paid tool. For example, you're limited to 100 links, and you can't search by prefix or folder, but it's handy for those quick link checks, or if you're doing SEO on a tight budget.
16. Google My Business
Basically, this is the #1, must-have tool for Local SEO — especially if you live in a market served by Google. It allows you to claim your business, manage listing information, and respond to reviews — among other things. Claiming your business profile forms the foundation of most other local SEO activities, so it's an essential step.
17. Google Review Link Generator
The Google Review Link Generator by Whitespark solves a simple problem - how do you give your customers a URL to leave a Google review for your business? Reviews drive rankings, but Google doesn't easily provide this. This generator makes it easy.
18. Local Search Results Checker
One of the hardest parts of Local SEO is figuring out rankings from any location — especially when Google stubbornly wants to serve results from the location you're in. BrightLocal solves this with a quick local ranking tool that can virtually drop you into any location on earth to check actual local rankings.
19. Moz Local Online Presence Tool
How consistent is your business information and local citations across the internet? Moz Local lets you quickly check how your business shows up across the web in the major data aggregators that Google and others use to rank local search results. Very handy to understand your strengths and weaknesses.
20. Mobile First Index Checker
Mobile versions of websites often differ significantly from their desktop versions. Because Google has switched to mobile-first indexing, it's important that major elements (links, structured data, etc.) match on both versions. A number of tools will check this for you, but Zeo's is probably the most complete.
21. Mobile-Friendly Test
The gold standard for determining if your page meets Google's mobile-friendly requirements. If your page passes the test, then Google counts it as mobile-friendly, which is a bonafide (albeit small) ranking factor. If your page isn't mobile-friendly, it will give you specific areas to address.
22. Chrome DevTools
Like Moz, SEMrush offers a full suite of all-in-one SEO tools, and they have a free account option that works well if you only work with a single website, or only need a quick peek at top-level data. The free account level gives you access to one "project" which includes basic site auditing, as well as limited keyword and domain reporting.
24. Sheets for Marketers
Sheets for Marketers isn't a tool, but a website that contains over 100+ free templates to perform a huge number of tasks using Google Sheets. Find powerful free sheets for everything including competitive analysis, site audits, scraping, keyword research, and more. This is a website for your bookmarks.
25. Rich Results Test
Did you implement review rating stars in your JSON-LD, and want to see if your markup is valid for Google's Rich Results? Getting a passing grade doesn't mean your page will automatically display rich results in the SERPs, but think of it as the cost of admission (the cost being free, of course.)
26. Tag Manager
On the surface, Google Tag Manager serves a simple purpose of allowing you to inject "tags" (such as Google Analytics) into your HTML. Beyond that, advanced users can leverage Tag Manager for a host of SEO functions. While Google recommends against using Tag Manager to insert important elements like structured data, it remains useful for a ton of SEO-related activities.
27. Bulk Domain Availability Checker
To be honest, we hadn't heard of this tool before, but several SEOs who regularly purchase domains praised it highly. It seems particularly popular with the black hat/PBN group, but the tool itself has white hat SEO legitimacy as well. Simply input up to 20,000 domains at a time, and it will quickly tell you if they are available. Beats the heck out of typing them in one at a time using Godaddy.
GTmetrix is one of many webpage speed performance tests that SEOs love to use. It provides familiar reports such as PageSpeed, YSlow, and Waterfalls, as well as automatically visualizing historic data for each page it analyses.
29. Page Speed Insights
Page Speed Insights is another Google tool built on top of Lighthouse, with one key added metric: Field Data. Field Data uses metrics collected by the Chrome User Experience Report so you can see how your page performs with real users across the globe. Not every page has data, but it's super useful when it does.
30. Yoast SEO
Yoast is the "name" in Wordpress SEO. The most trusted name, the most installed (30 million sites) and often, the most innovative. With the help of our friend Jono Alderson, they've created some amazing advances in the delivery of structured data. I personally use Yoast on most of my Wordpress sites, and they are obviously highly recommended.
