  1. Hi Robin,

    Wow..what a great list you have given us. I have used a few of them here especially the broken link checker. OMG…I spent an entire weekend on that one once. I couldn’t believe it. So now I use it frequently to keep things updated.

    I have also used the web page test. I have two sites and need to make sure they are up to par. Yippie..they are!

    I will be checking out some of the others. Thanks so much for putting this together.


    • Hi Donna,

      I’m so glad to hear that you like this list of free SEO tools. I use the broken link checker on a number of sites as well. It is amazing at how many links actually become broken over time, isn’t it?

      The web page test is also a great choice at pointing out areas that we need to work on. I’m happy to hear that you are using it on your two sites.

      Thank you for stopping by and for your comment. I would love to hear what you think of the other tools when you have the chance to test drive them.

    Hey Robin,

    thank you for this excellent tools roundup,

    Good to see Uber Suggest mentioned here – been using it for ages now. I have got plenty of niche blogging ideas from this tool alone. It is a bit under-mentioned and a hidden gem.

    CoSchedule is another of those great tools which helps so much. Also, Semrush, ahrefs, quicksprout etc. – all are great tools.

    • Hi Shobha,

      I’m glad to hear that you like the tool roundup. You are so welcome!

      Yes, UberSuggest is a great tool. I have been using it for ages, too. It is a hidden gem. I love CoSchedule as well as SEMRush, Ahrefs’ Site Explorer and Backlink Checker, and QuickSprout, too.

      I appreciate you stopping by and commenting. Have a wonderful weekend ahead.

  3. Hey Robin,

    This is a nice list of tools you have here and most of them I never heard of. Ive used mainly SEMRUSH and broken link checker and they have been a tremendous help to me.

    I’m definitely bookmarking thus site and will come back to use this as a reference. I’ve been looking for it other keyword tools and it looks like I have a good start now after reading this post.

    Thanks for the share! Have a good one!

    ✿ Hi, Robin,

    Wow, what a cool post about free SEO tools, love it! I’ve used some of the tools you mentioned, but had never heard of Remove’em. What a great service! However, I didn’t see the free plan just three paid options. Could you point me in the right direction please?

    Thanks so much for sharing, will definitely be spreading the word.

    Have a wonderful weekend.
    Carol Amato

    • Hi, Carol,

      Thank you for stopping by, for taking the time to read this, and for your comment. I’m happy to hear that you like this list of free SEO tools!

      I agree. Remove’em is a great tool. There is a free option that will give you a sampling of the anchor text break down of a domain name. The tool helps to identify anchor text diversity and will highlight those areas where you might be at risk for anchor text over optimization. The report shows values for root domains (unique linking domain), total links (unique links), and mozRank (authority measurement) for each anchor text used in links to your site.

      I revisited the site and do see what you mean. To obtain the free sampling report, enter your domain name in the box on the home page and click the “Predict” button. Then on the pop up, select the “Click here” link for a sample report showing your anchor text breakdown.

      Thank you again for stopping by. Have a wonderful week, too!

  5. Gisele Grenier says:

    WOW, that’s a great list. There are a few on there that I’ve tried and some I’ll have to check out.. One of my favourite SEO tools is Yoast SEO and the Broken Link Checker.

  6. Ian Campbell says:

    Great list of tools Robin! Some I have used, others I have not heard about. I like the sound of Uber Suggest and think this will be my “go to” keyword tool in the future. Thanks for sharing. Cheers, Ian

  7. I love this list, Robin, and I love the fact that I am using the majority of these tools to check for off page and on page optimization. There is one that I did not know of and which is precious – Remove ’em. I’m going to check it this week.

    Thanks for the comprehensive list.

    • Hi Vatsala,

      It is great to hear that you found this list helpful and that you are already using the majority of the tools. Remove’em does have a paid option, but they will give you a free sampling. Please let me know what you think if you do decide to give it a try.

  8. Great list of tools, especially the keyword search ones. Will check those out. I do use headliner. Not big on technical stuff but I know they are important.

  9. Joe Butka says:

    Gisele and I work closely together and SEO is her cup of tea. Many tasks we share and many we have equal input and there are some whereby we rely on the other to be more versed.

    • Hi Joe,
      It is so nice to meet you! You are very fortunate to have Gisele to help with SEO. Having a team that compliments each other’s strengths is golden.

      I appreciate you stopping by and your comment.

  10. Another great post, Robin with a wonderful list of tools to use to optimize our websites. I do use Yoast SEO and do use a headline checker as well. Some of the functions I realize are built into things like MailChimp (for my newsletter headlines) and of course I use other tools as needed. It seems there are more tools and tricks to keep on top of daily, and as someone who doesn’t want to be so heavily involved in the technical aspects of the online world, it helps to have posts like this to refer back to! Many thanks!

    • Hi Beverley,
      It is great to hear that you are using both Yoast SEO and a headline checker. Both are excellent tools. MailChimp’s headline analyzer is another great tool! There does seem to be a great deal to keep on top of on a daily basis. I’m happy to hear you like this post.

    I understand the importance of SEO and with over 667 million website out there, ‘getting it right’ is a worthwhile investment to make sure your website gets found by the search engines! Not only are these SEO tools invaluable Robin, I’ve also picked up other great tips from reading your blog. In particular, the title tags being the single most important “on page” element in telling a search engine what your page is all about.” Definitely a worthwhile read with great tools as a bonus!
