33 Free SEO Tools You Should Know About

If you like SEO tools and you’re a fan of free stuff, you’re going to LOVE this list of free SEO tools. The list is organized into 11 categories, and each category broadly describes a popular SEO task (e.g., Backlink Investigation, Keyword Research, SEO Analysis, etc.).

I’ve included a brief overview of each tool’s free functionality (some of the tools are freemium), screenshots, videos, and links to documentation for the more complex tools. Hopefully, this resource will give you everything you need to start mastering these amazing tools.

So without further ado, let’s jump into the list…

Backlink Investigation

For years, your site’s backlink profile played a vital role in your site’s ability to rank well in the search engines. Now, in the post-Penguin era, that backlink profile is more important than ever. With that in mind, the following free SEO tools will help you investigate a site’s backlink profile.

1. Open Site Explorer

Open Site ExplorerAfter Yahoo! Site Explorer’s untimely demise in 2011, Open Site Explorer (OSE) became one of the most popular backlink checking tools. OSE uses the freemium model, and without an account, you are limited to running 3 reports per day.

The following screenshot shows an example report:

Open Site Explorer resultsIf you register for a free account, you have access to 1,000 backlinks for a given URL, and the first 15 backlinks include additional information such as the link’s anchor text, Page Authority, and Domain Authority. Each report also includes summary information about the requested URL: its Page Authority, Domain Authority, number of linking root domains, and number of total links.

2. Majestic SEO Site Explorer

Majestic SEO Site ExplorerMajestic SEO Site Explorer is another popular backlink checking tool, and like OSE, it uses a freemium model. Without an account, you are only able to access general summary information about a requested URL or domain (e.g., number of referring domains, number of external backlinks, number of referring IP addresses, etc.).

If you register for a free account, you receive additional summary information (e.g., a backlink breakdown), and you also get access to the top 5 backlinks, top 5 referring domains, and top 100 pages (based on the number of referring domains) for your request.

For more information, read Julie Joyce’s Majestic SEO review.

3. Ahrefs Site Explorer

Ahrefs Site ExplorerAhrefs is one of the newest backlink checking tools, but it already has a very loyal user base. Similar to most of its competitors, the tool uses a freemium model.

As a guest, you are allowed to perform 5 requests per day, and if you register for a free account, that allowance increases to 15 requests per day. Each request returns a backlink overview as well as specific information about individual backlinks (for free accounts, only the first 5 backlinks display additional information).

The backlink overview includes information such as the total number of backlinks, the number of referring domains (and a corresponding TLD breakdown), and a breakdown of the backlink types (e.g., text, image, nofollow, etc.).

For a given request, free accounts receive access to the first 500 backlinks. The first 5 backlinks display the link’s Ahrefs rank, source URL, source title, destination URL, anchor text, type, and crawl date. However, the remaining backlinks only display the link’s Ahrefs rank, source URL, and source title.

For more information, check out Eric Covino’s Ahrefs Review.

4. Link Diagnosis

Link DiagnosisLink Diagnosis is a completely free backlink checking tool, but unless you install the corresponding Firefox extension, you will only receive a limited view of the results (the “lite report”). Without the Firefox extension, the tool displays the first 250 backlinks, along with each backlink’s anchor text, mozRank, Page Authority, and Domain Authority.

With the extension installed, the 250 backlink restriction is removed, and the tool presents each backlink’s title (i.e., the title of the linking page), link type (e.g., nofollow), PageRank, outbound link count, modified outbound link count, and LinkStrength (in addition to the information displayed without the extension).

Server Investigation

When diagnosing an SEO issue, it is often useful to investigate the site’s Web server. Whether it’s identifying a server’s technology stack, uncovering the source of performance bottlenecks, or troubleshooting HTTP headers, the following free SEO tools can help.

5. BuiltWith

BuiltWithvvvvvBuiltWith provides a technology profile for a given site, which includes information about the site’s server, frameworks, advertising, analytics, JavaScript libraries, and much, much more. You enter a website’s URL, and the tool essentially performs a technology X-ray.

Here’s a screenshot of the tool’s technology profile:

BuiltWith technology profileThe tool also provides a simple SEO profile, which checks a page’s title, meta description, H1 tag, content keywords, images, response speed, and social sharing.

6. Pingdom Full Page Test

PingdomPingdom offers a free online tool that analyzes a URL’s load time. You simply enter a URL, and the tool displays a summary of the page’s load time, size, and number of corresponding HTTP requests.

Here’s a screenshot of Pingdom’s results:

Pingdom resultsAs the screenshot shows, the tool also presents a waterfall visualization that displays the load time and size of each of the page’s objects.

7. Google PageSpeed

Google PageSpeedPageSpeed is a free online tool (plugins are also available) that tests a URL’s load performance. You enter a URL, and then, the tool presents a list of performance-based suggestions (e.g., optimize images, minify JavaScript, etc.), which are categorized into high, medium, and low priority items.

8. URI Valet

URI ValetURI Valet is a free online tool that displays the HTTP headers exchanged during a request for a given URI. The tool also presents a summary of the corresponding HTML’s <head> tags and a breakdown of the various objects (e.g., scripts, images, etc.) that are downloaded when accessing the URI.

9. SpyOnWeb

SpyOnWebSpyOnWeb identifies multiple sites that probably belong to the same owner. On the backend, the service clusters sites that share an IP address, Google AdSense ID, Google Analytics ID, Yahoo! Publisher Network ID, or Yandex.Direct ID. Then, when you query a website’s URL, the tool presents a list of sites that have been clustered together with that URL using the previously listed information.

Website Crawling & Link Checking

One of the best ways to identify SEO-related problems with your site is to crawl its pages and look for issues. These issues can be markup-related (e.g., duplicate titles), or they can be link-related (e.g., broken links).

10. Screaming Frog SEO Spider Tool

Screaming FrogThe Screaming Frog SEO Spider Tool is a freemium desktop application that allows you to crawl and analyze the pages on your website. The tool is free for the first 500 URI requests and £99/year after that.

For each request, you receive a wealth of information, including the page’s title, meta description, heading tags, image info (e.g., alt text), link info (e.g., are they nofollowed), and much, much more. Rather than bombard you with screenshots, here’s a video that demonstrates the tool’s functionality:

11. Xenu’s Link Sleuth

Xenu Link SleuthXenu’s Link Sleuth is a free desktop application that checks for broken links on your website. The tool also displays page titles and meta descriptions, but its primary purpose in life is to quickly crawl a website and identify the status codes of the site’s links.

12. W3C Link Checker

W3C Link CheckerLink Checker is a free online tool that checks the validity of links for a given URL. You simply enter a URL, and then, the tool recursively checks the URL’s links for URI scheme errors, redirects, and error status codes.

Content & Markup Analysis

Your site’s on-page ranking factors are derived from the site’s content and markup. Consequently, it’s extremely important that you optimize the content and minimize errors in the markup.

13. SEO Browser

SEO BrowserSEO Browser is one of the oldest free SEO tools, but it is still incredibly useful. The tool is 100% free, and it offers two modes: Simple and Advanced. The Simple mode displays a given URL like a text-based Web browser (e.g., lynx). The Advanced mode provides a text-based view of a URL, and it also includes useful information that summarizes the URL’s content (e.g., page title, meta tags, page size, word count, IP address, etc.).

14. Copyscape

CopyscapeCopyscape is an online duplicate content detection tool that uses a freemium model. You simply enter a page’s URL, and the tool returns a list of pages that are duplicating the URL’s content. With a free account, the tool only displays the first ten results, and the tool only allows a certain number of monthly requests for any given site (this limit is irrespective of the IP submitting the request).

15. W3C Markup Validation Service

W3C Markup Validation ServiceThe Markup Validation Service is a free online tool that checks the markup validity of the Web document associated with a given URI. You simply enter a URI, and then, the tool checks its correctness (based on the syntax of its document type). Finally, the tool displays an itemized list of errors and warnings (with corresponding line and column numbers) that it finds during the validation process.

Here’s an excerpt from the tool’s validation output:

W3C Markup Validation Service results

Keyword Research

When attracting potential customers, it’s important to speak their language. If your site isn’t using the keyword phrases that people are searching for, those people will have a difficult time finding you. Fortunately, a number of free keyword research tools exist.

16. Google AdWords Keyword Tool

Google AdWords Keyword ToolThe AdWords Keyword Tool is one of the most popular free keyword tools available. The tool gives you three options for querying keywords: (1) input a list of keywords, (2) input a URL, which the tool scrapes to identify keywords, or (3) select from a predefined list of categories.

Once you select a querying method, the tool allows you to slice and dice the results using a variety of filters, match types, and keyword term inclusion/exclusion lists.

Here’s an example of the tool’s results:

LDA Content Optimizer results

Competitive Keyword Analysis

Are they targeting keywords that you haven’t considered? The following free SEO tools can help you answer these types of questions.

20. SpyFu

When you enter a keyword, the tool presents summary information, which includes the keyword’s CPC, average click count, and search volume. The keyword report also displays the top PPC domains, organic search results, and related terms.

27. MyBlogGuest

28. DoubleClick Ad Planner

30. Google Webmaster Tools

Google Webmaster ToolsGoogle is the most popular search engine in the world, and as a result, Google Webmaster Tools (GWT) is one of the most useful free SEO tools available because it gives you direct access to some of Google’s information about your site.

32. blekko
Update [8/16/2012]: blekko no longer offers free SEO data (it’s now $99/month – insane, I know.) For now, I’m keeping them on the list for nostalgic purposes, in hopes that they eventually come to their senses.

blekkoblekko is a search engine that has been steadily gaining popularity over the years. Unlike its bigger and more recognized competitors (e.g., Google and Bing), blekko is significantly more transparent about its index information. Specifically, every search result has accompanying SEO data, which includes backlinks, duplicate content analysis, and crawling stats (e.g., number of crawled pages).

    Fantastic article! Thanks for all the free tools…much appreciated.

    • steve May 23, 2012 at 12:54 pm #

      You’re very welcome! I’m glad you enjoyed it :-)

  2. Aaron Bradley May 23, 2012 at 12:46 pm #

    Great list – thanks for this Steve!

    A suggested addition to this list, if I may (especially as you include the W3C Markup Validation Service on your tool list). That being the Rich Snippets Testing Tool from Google:
    http://www.google.com/webmasters/tools/richsnippets

    This tests structured data markup (microformats, microdata, RDFa – and, to a certain extent, Open Graph metadata) and validates that Google can correctly parse the data. It displays errors in the case of invalid markup, and for valid markup attempts to provide a display of a rich snippet that might be generated for the content, where applicable.

    A recent improvement now permits direct entry of code, in addition to the original validation of URLs.

    • steve May 23, 2012 at 1:00 pm #

      Thanks for your kind words Aaron!

      And I completely agree with your suggestion. Google’s Rich Snippets Testing Tool is incredibly valuable, and it will become even more useful as Google continues to use more rich snippets in the SERPs (and as the Knowledge Graph becomes more integrated).

  3. Matt May 23, 2012 at 3:22 pm #

    Hi Steve – great list and thanks for putting it together. Have you tried our Keyword Eye tool (http://www.keywordeye.co.uk/) before? It’s a visual keyword suggestion tool primarily but we have been added new SEO & Twitter reports to it recently. Would love to get your feedback on it – and hopefully it could find a place on your SEO tools list! :)

    • steve May 23, 2012 at 7:03 pm #

      Thanks Matt!

      I haven’t played with Keyword Eye before, but it looks cool. I’ll have to play with it more.

      Thanks again for the suggestion!

  4. Vic May 23, 2012 at 6:40 pm #

  12. Pawel Rabinek May 24, 2012 at 9:09 am #

    Great set of SEO tools. Good article and it’s very useful.

    Have you ever tried http://www.seoptimer.com a free tool for SEO on-page analysis? It’s much better than Woorank, because you can check any page of your website. Maybe it’s worth to add as 34th position of your excellent list? ;)

    • steve May 24, 2012 at 9:42 am #

      Thanks Pawel!

      I haven’t used Seoptimer. I’ve have to give it a whirl :-)

  13. Jonas Schmitt May 24, 2012 at 2:47 pm #

    Great stuff! Have used a bunch of these. Love the free stuff as a freelancer :) Seoptime seems like an interesting new acquaintance.

    I’ve also been using http://www.cuutio.com for a while. They haven’t been around for long but offer a free service for keyword positions, competitor comparison metrics.. stuff like that. What makes it interesting is the history data for each keyword (like top100 results for every week) with e.g. highlighted competitors. They also report adWords positions but it doesn’t seem to be accurate all the time.

    The negative thing for me is I can get only 10 keywords and 3 competitors monitored for free.

    • steve May 24, 2012 at 5:04 pm #

      Thanks Jonas! I’m really glad you like the list :-)

      I’ll have to check out that keyword service.

  14. imdumping May 24, 2012 at 3:34 pm #

    Very list, thank you steve. :)

    • steve May 24, 2012 at 5:06 pm #

      You’re welcome… glad you like it ;-)

  15. Rizwan May 24, 2012 at 3:38 pm #

    Well done Steve, you did a great job. This kind of list should be updated after a span of time as due to SEO environment changes unexpectedly. I found few new tools which I never used. Aside I use SEO Book toolbar, It gives you all basic features that you need to use in daily routine.

    Please share your thoughts If you’ve used SEO Book toolbar.

    Thanks
    Rizwan

    • steve May 24, 2012 at 5:11 pm #

      Thanks Rizwan!

      I have used SEO Book’s toolbar in the past, but it’s been a while (I didn’t include it in the list, but I linked to it in a previous comment).

      I’ll have to give it another whirl :-) And I completely agree with you about keeping the list of tools updated. When you search for similar lists of free SEO tools, they’re flooded with links to defunct tools such as YSE. I’ll do my best to avoid letting that happen to this post.

      • Rizwan May 26, 2012 at 6:51 am #

        Exactly!!! My point was exactly towards YSE.

        • steve May 26, 2012 at 7:15 pm #

          If you ever find a defunct tool on this list, please let me know! I’ll do everything possible to avoid letting the list become a graveyard for outdated tools :-)

          • Rizwan May 29, 2012 at 1:29 pm #

            Sure Steve. But so far the list is pretty excellent. Thumbs up!

  16. Renukhanna May 25, 2012 at 3:30 am #

    useful SEO tools thanks for sharing with us .

  17. Arnaud YHUEL May 25, 2012 at 8:42 am #

    Nice article Steve! All listed, I think you don’t forget anyone…or almost. I would add ScrapeBox because even in White SEO, it’s awesome.
    Then, I know a very practical tool, K-Html, but it exists only on French. I talked about it on my blog: http://blog.mediamiu.com/la-liste-des-meilleurs-outils-seo/

    Hi Steve! Thanks for sharing this post. The tools you listed here sure are useful. Although blekko is pretty new to me. I visited it and, I must say, it looks pretty good. I’ll be sure to check it out more.

    Aside from socialmention, we’ve been checking Topsy.com as well. It looks promising, too.

    You know, we’ve also compiled a list of free SEO tools. It’s an eBook titled 18 Free and Commercial SEO Tools (http://wirewalkersva.com/18-free-and-commercial-seo-tools-1/). Please check it out when you have the time. It’s Free to download for everyone.

      You’re welcome… I’m glad you enjoyed the post :-)

      I’m also a big fan of Topsy, but I didn’t want to go overboard with social media tools on this list. If I ever make a social-specific list, Topsy will definitely be on it.

    Thanks Daniel… I’ll give it a look :-)

  20. Paul July 31, 2012 at 8:36 am #

    This is a seriously good list and well presented. Spyfu is one I wasn’t using but am now for sure.

    • steve July 31, 2012 at 11:21 am #

      Thanks Paul! I’m really glad you enjoyed the list, and you’re right: SpyFu is a great tool :-)

    Wow, definitely a huge list Steve, nice job.

    It’s crazy how many tools there are out there.

    Scriptalicious also has a huge number of free SEO tools, you might consider adding here:

    Those are just the free public tools – you can also use the SEO Scripts Demo:

      Thanks for the comment :-) I’m really glad you enjoyed the list!

      The funny thing about that Quora thread is that I already summarized this post on there ;-) But I agree with you… it’s a great place to find even more free SEO tools.

  25. steve October 31, 2012 at 12:17 pm #

    Thanks Ivana; I’m really glad you like the list :-)

    I just checked the tool you mentioned, and you’re right: it provides a lot of helpful SEO information. Thanks for the pointer!

    Great list! Thanks for sharing this with us. I also use builtwith.com. That Tool tells lots of information about what is sitting behind a website – e.g. framework, CMS, analytics package etc.

    • steve January 10, 2013 at 12:44 pm #

      Thanks Perry! You’re absolutely right… BuiltWith is one of my absolute favorite free SEO tools.

  28. Bryan January 15, 2013 at 4:39 pm #

    Steve, great list! I think I use 22 of these at least semi-regularly.

    I’ve used SharedCount for awhile, but my team has also created a separate tool that might be a good addition to your list. We created it for at-a-glance metrics to see how our (or our competitors’) most recent blog posts were performing. It shows social sharing metrics for a blog’s recent posts when you enter the RSS feed:

    Would love to hear your thoughts on it. Thanks again.

    • steve June 2, 2013 at 8:41 am #

      Hi Adam,

      I’m really glad you like the list :-) I’ll be sure to take a look at your free SEO tool.

      Thanks for commenting!

    Thank you so much for the information. I am still a bit green in knowing what tools might be useful for our small business. Additionally, since we are not trying to target the general population but rather professionals within the industry, I am wondering how “Advanced” I might need to be with some of these tools?
    Again, I am grateful for the information!

    • steve August 6, 2013 at 10:19 am #

      Hi JD,

      You can derive value from all of these free SEO tools, but since you’re a small business, I also recommend GetListed.org.

      It’s an excellent free tool for identifying local citations that need to be added/modified/etc.

      Thanks for the comment!
