  • The 30 Free SEO Tools You Must Know

    Recently a “101 free SEO Tools that don’t suck” list went popular on Sphinn. I love 101 items lists and I love free SEO tools especially if the tools “don’t suck”. While checking out the list I’ve encountered some tools I haven’t been using much or been familiar with at all. On the other hand I was missing some tools I use daily. When I noticed that the list actually contains SEO tools that measure the so called keyword density I finally decided to compile my own list.

    Here I want to focus on those few free SEO tools you must know to be able to practice SEO in a meaningful way.

    Using 101 tools for whatever purpose is not productive. At the end of the day you got to find your set of say 10 or 12 tools you’ll use. Everything else is just playing around and wasting your precious time. Thus this list will be the size of the usual SEOptimise list, approx. 30 items. I’ll concentrate on free SEO tools here as everybody can test them this way. Some of them are freemium that is they offer basic functionality for free and make you pay for the full fledged product.

    This list of the 30 free SEO tools you must know will be a mix of

    • web based tools
    • stand alone software
    • Firefox extensions

    Keyword Research

    Site Check

    Link Tools




    Take note that I did not mention some of favorite tools because they offer no free version. Also it was important to me that you don’t need to register to use these tools. All of the tools do not require a sign up or log in with the exception of a tool by SEOMoz which is a highly trustworthy SEO provider.

    Many thanks to all the knowledgeable SEO practitioners on Twitter who contributed to this list, in no particular oder:


    Of course this list is highly subjective.
    Plus, I’m quite sure I forgot and left out a tool on purpose you rather would want to see in a “must know” list. So make sure this tool gets a mention too.

    I help people with blogs, social media & search. I help you succeed on the Web. I've been online publishing for 15 years. I started back in 1997.

      Interesting Post! As of now, I know only part of the SEO tools. After seeing your article, I am aware of remaining tools. Thanks a lot :)

    6. Angela Hill says:

      Great list. I would add: http://www.websitegrader.com for analyzing your site’s ranking vs your competition and http://www.crazyegg.com for analyzing user experience via a heat map.

    7. Ron Knight says:

      Wow man, this is an awesome list of SEO Tools. It helped me a lot. Thanks for sharing.

    8. Tad Chef says:

      Thanks all for the feedback! Much appreciated!
      Angela: Thank you. Both of them almost made it, Crazy Egg does not offer a free version though. Website Grader is a great tool for the average webmaster but I don’t use it as a SEO. I only trust my own judgment when it comes to grades. For instance it say “No Meta Keywords Found” on my page.

    9. Matthew Kettlewell says:

      I’d also add the FireFox plugin Web Developer… great way to get insight into the On Page SEO factors… my favorite is the “disable cache” so that my changes aren’t held in limbo!

      And of course Firebug too, for interactive changes, and speed testing.

      I was at a tech roundtable the other night and our resident WordPress guy said he swears by the All In One SEO plugin for WordPress. Said it seems to yield great results for him.


    14. whoa, had no idea there were so many. Time to check some of these out and see which ones I have been missing out on. Good post.

    15. nanang says:

      wow. Good info, thanks

    16. Also:
      ClickTale.com (allows you to record user sessions for analysis)
      myIPNeighbors.com (see what other sites are hosted on a server)

    17. Jon says:

      Thanks for the list, Tad, you showed a couple of new tools to me. I’m going to check them out. Also I think the free edition of SEO PowerSuite tools could be added to your list

    18. There are some great tools out there when it comes to SEO and online marketing. I know the wordtracker labs have some really great stuff out there.

    28. Tad Chef says:

      Hello everybody. Thanks for the feedback.
      # Web Develeoper is a good idea.
      # Firebug for SEO purposes? Nice to have.
      # seomoz.org/term-extractor is great, the other two are OK but not worthy of this best of list IMHO.
      # Clicktale is a good idea as well but its free version is very limited.
      # myIPNeighbors.com is useful but not indispensable for SEO I think.
      # Link Voodoo is weird, it makes you download a php script to your computer. I won’t allow that for security reasons.
      # SEO PowerSuite is fine but it doesn’t let you save your inputs or results in the free version which is very limiting. Also their GUI fonts are sooo tiny I barely can read them.

      Did I overlook a suggestion?

      one of the best ones i have alwasy used is scrubtheweb.com

    81. Ron James says:

      Where’s scrub the web? I see only one mention of them here and yet they are absolutely the best. Most so called SEO tools do not work. SEO Book is a total joke and SEOmoz for example does weekly crawls and rank tracking which violates every search engine’s terms and conditions, but that is SEOmoz’s claim to fame. What good does it do you to know that your competition is outranking you? Real SEO tools will help you discover the reasons others are outranking you.

      Search engines index “content” and they are looking at your web pages. How you place words on the page makes all the difference. Want to rank for “apple”, then consider adding the word “fruit” to your page along with apple and watch your rankings improve. The simple truth is, if you are not making changes to your content, you are not doing SEO. Real SEO professionals know this and that is why their services are expensive. I admit I am a member of stw and it was the best choice I have made. Without stw’s tools I don’t know how you would discover these things. I have also purchased SEOmoz as well as SEO Book with zero success. While they both have a few good videos, their tools are horrible and do nothing for you. I won’t publish a web page without first using stw’s tools.

      Just my opinion,

    82. Seo Man says:

      Some features of these plugins are in addition RDS bar for FireFox. It is easier to use. Try it!
