10 SEO Analysis Tools You Should Be Using

In a previous post, I presented a massive list of free SEO tools that can help you accomplish various SEO tasks (e.g., backlink investigation, keyword research, etc.). I received a lot of positive feedback about that list, but people consistently requested more SEO analysis tools.

Since I’m a man of the people, this post is completely dedicated to SEO analysis tools. For each tool, I’ve provided a brief overview of its functionality, and I’ve also included helpful screenshots along the way. After you finish this post, your SEO analysis toolbox should be overflowing with goodness!

Now, let’s get started…

#1 WooRank


WooRank is a freemium tool that provides an “instant website review.” Without a premium account, you are only allowed to generate a limited number of free reports, but you are able to view previously generated reports. Also, the tool currently offers a 7-day unlimited free trial, which gives you access to unlimited reviews. If you’re interested in purchasing a plan, the cheapest one is $49/month.

Here’s the summary view from a WooRank report:

WooRank report

The report is divided into the following 8 sections:

  • Marketing Checklist – These are the most important action items for your site.
  • SEO – This section checks if the site is following various on-page and off-page SEO best practices (e.g., appropriate title and description, keyword consistency, backlink count, www/non-www canonicalization, XML Sitemap usage, etc.).
  • Mobile – The mobile version of your site is displayed, and the site’s adherence to mobile optimization best practices is evaluated.
  • Usability – This determines if your site is user-friendly by evaluating various usability best practices (e.g., the existence of a custom 404 page, above the fold content, structured markup, etc.).
  • Technologies – This section investigates miscellaneous aspects of the site (e.g., W3C standards compliance, speed optimizations, etc.).
  • Social – This quantifies your site’s popularity on social networks, and it reproduces various social data found elsewhere (e.g., profile information on Facebook, Twitter, Google+, etc.).
  • Local – This section presents your site’s listings in local directories (e.g., Yelp, Foursquare, etc.) as well as online reviews associated with those listings.
  • Visitors – This measures the site’s popularity based on various traffic estimates.

#2 SEO Site Checkup

SEO Site Checkup

SEO Site Checkup is a free SEO analyzer that analyzes your site (and an optional competitor) using 45 individual checks in 6 different categories. Based on the results of those checks, the tool generates a summary, which includes a numerical score for the site and a count of the failed checks:

SEO Site Checkup summary

Below the summary, the tool presents the results of the 45 checks using the following sections:

  • Common SEO Issues – This section includes a wide variety of SEO checks (e.g., keyword usage in important markup areas, an appropriate code to text ratio, the existence of a robots.txt file and an XML Sitemap, HTML standards compliance, SEO-friendly URLs, etc.).
  • Speed Optimizations – This covers various load performance-related checks (e.g., page size, compression, caching, minification, server speed, etc.).
  • Server & Security – This section identifies a few important hosting and security characteristics of the site (e.g., proper canonicalization, appearance on suspicious blacklists, providing unnecessary access or displaying potentially sensitive information, etc.).
  • Mobile Usability – This checks if your site is mobile friendly by providing a snapshot of what it looks like on mobile devices and looking for media queries.
  • Social Media – This section helps quantify the site’s social engagement by providing share counts for various popular social media sites.
  • Semantic Web – This tries to determine if the site is using structured data (e.g., schema.org microdata).

#3 Site Auditor

Site Auditor

Site Auditor is one of the SEO tools provided by Raven Tools as part of their Internet marketing solution. After you run Site Auditor on your website, the tool presents a report that summarizes its findings.

Currently, Raven Tools offers a 30-day free trial for Site Auditor (and all of their other tools). Once your free trial expires, the least expensive premium plan is $99/month.

Here’s an excerpt from a Site Auditor report:

Site Auditor report

The report is broken into 9 different sections:

  • Meta – This section identifies the site’s most important metadata and corresponding duplication (e.g., duplicate titles, duplicate meta descriptions, etc.).

  • Crawl Comparison – This compares different crawls of the site (performed at different times) to evaluate how the site’s issues are changing over time.

#4 HubSpot’s Marketing Grader

HubSpot Marketing Grader

Unlike many of the other SEO analysis tools on this list, which focus primarily on your site’s SEO activities, Marketing Grader digs a little deeper into your company’s online marketing strategy.

Here is an example of a Marketing Grader report:

  • Blogging – This section investigates your blogging activities (e.g., does your site have a blog, does it have social sharing buttons, etc.).

  • Lead Generation – This section analyzes the effectiveness of your landing pages (e.g., are you using forms to capture leads, are you using analytics software to measure your results, etc.).
  • Mobile – This section determines if the page is mobile-friendly (e.g., are you using @media queries or a mobile stylesheet, do you have a meta viewport tag, what does the page look like on mobile devices, etc.).

#5 Site Analyzer

Site Analyzer

Site Analyzer is another free SEO analyzer, and it presents 71 data points, which are organized into 5 groups. After you perform an analysis on your site, the tool presents an overview, which includes a global score as well as accessibility, design, texts, multimedia, and networking scores.

Here is an example of the tool’s overview:

#6 SEO Workers

SEO Workers

Here’s an excerpt from one of those reports:

  • Visitors – This estimates the number of visitors your site receives, and it helps quantify the site’s social engagement.

#8 UpCity Free SEO Report Card

It’s Your Turn!

I would love to hear from you in the comments. Which of these tools is your favorite? What other SEO analysis tools should everyone be using?


  1. says

    NIce list. I’ve used about half of those. Woorank is pretty quality for what you can get for free. I would say though that a good SEO brain is always the basis for any analysis. I mean, tools are great, but you need a sharp brain to make it all work. Plus machines will always miss nuances that a good SEO will catch.

    • steve says

      Thanks for the comment Scott! I agree that a good SEO brain is the most important component for any analysis, but tools definitely help minimize the tedious work so you can focus your brain power on the most difficult tasks :-)

      Thanks again for reading and commenting!

  2. says

    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 says

      Thanks for the comment Philipp! And you’re right… BuiltWith is a great tool (it’s on the list of 33 free SEO tools I mentioned at the top of this post).

  3. says

    By the way, if you look for a powerful crawler, then you should use screamingfrog.co.uk /seo spider/. The basic version is free and can tell you a lot about the onpage factors of your site. I hope it helps you.

    • steve says

      Hi George,

      This is probably blasphemy so I’m going to whisper… I don’t use any paid tools.

      I spend most of my time doing SEO audits, and my entire workflow uses custom tools that I’ve written myself (or free tools).

      In the past, I’ve used the paid versions of the top backlink tools (e.g., Majestic, Ahrefs, OSE, etc.), but I was doing so much analysis work on my own that it stopped making sense to pay for a lot of the functionality I already had in-house.

      With that said, I’m probably going to re-evaluate a lot of paid tools in the coming months so I’ll definitely let you know if I go back to any of them (or incorporate new ones into my workflow).

      Thanks for the comment!

    • steve says

      Thanks for the comment Keith! I’ll have to check out the tools you mentioned. Thanks again for reading and commenting :-)

  4. says

    Great Post! Lots of great tools in here. One tool I found useful was the FOUND SEO Audit Tool. That tool helps me a lot when I’m doing website audits.

    SEO Workers is great and these others are good too, bit hard to believe that they’re free!

    Thanks for this and sharing some great tools!

    • steve says

      Thanks for your kind words :-) I’m really glad you found the list useful.

      I’m right there with you… I’m constantly amazed by how much people are willing to give away for free. I love being in an industry that is so open and helpful!

  5. says

    Very informative article ! I have been using woo rank for 6 months & while searching more seo analysis website like woo rank & found your site very informative thank you :)

  6. says

    Lipperhey is awesome. the graphic it produces that points to the various web page parts is awesome to help explain deficiencies and onpage SEO concepts to my clients! Great list!

  7. says

    Hey Steve,
    This is a nice list, indeed. My current employer sent me to your website. I am doing SEO work for him right now and am having a not so easy time getting his employers company at the top of all Google pages. So, I am hoping one of these 10 SEO help sites will work for me.

    • says

      Hi Monica,

      I’m really glad you like the list! If you need more SEO analysis resources, just let me know. SEO audits are our bread and butter :-)

      Thanks for the comment!


  8. says

    This is the most useful post I have read recently. Great thanks for collecting these services. These sites can really help with SEO and your service is also incredibly useful. Thanks!

  9. says

    Thanks for such a nice collection of SEO analysis tools. I have used 5 from the above list and find all of them to be very useful.

    Many Thanks again.

  10. Vikram Rathod says

    Great share steve, your list help me a lot. I found some new tools for optimizing site and solve lots of problem. Woo rank is one of my favorite and also helpful. I have receive so many different suggestions and errors by using some of tools from your list.
    Thanks a lot :)

  11. says

    Great article, I have tried most of those tools, Since Raven Tools and AHREFS lost their Google Keywords API ive been on the lookout for more tools that I can use and that are affordable for a freelance SEO like myself.

  12. says

    Hi Steve. If I wanted to focus on SEO results from South Africa to our site, which of these Tools would be most effective. I’ve come across some tools that only focus on US or Global results. Thanks

    • says

      Hi Mark,

      Unfortunately, I don’t know of any tools that are focused on SEO analysis for South Africa. However, most of these tools should be country-agnostic, assuming the site’s language can be tokenized based on whitespace.

      If the tools on this list don’t work for you, let me know on Twitter (@SteveWebb), and I’ll try to point you in the right direction :-)

      Thanks for commenting!

  13. says

    I was really sad when Woorank decided to start charging for their services. The one report a week sometimes is not enough, but I can understand them wanting to turn a profit. Out of all the tools I have used it is still the best in my opinion.

    • says

      WooRank is definitely still one of my favorite SEO analysis tools, and you’re right: it’s hard to fault them for wanting to make some money :-)

  14. says

    Great little list, I have used SEOmoz for their on-page report but found it was quite expensive for something I got very little use out of. Woorank looks perfect but again its quite a lot to pay every month when you just want the on-site reports.

    Going to look into Traffic Travis though so will see how that holds up

    • says

      Thanks for the comment! Let us know what you think about Traffic Travis. It’s been around for a while, and it’s definitely one of the best free options out there.

  15. says

    Hey Steve,
    These tools are great! And… you’ve got a huge list of them too. The only thing that’s throwing me off is when I hit tab to switch comment fields (i.e. name, mail, etc), it jumps me to your “subscribe” field and I have to scroll ALL the way down again LOL. Anyways, it was worth me stopping by!
    Thanks again!

    • says

      Thanks for the comment, Leon. You can do a lot with 1 free analysis report :-) Once you’ve established a baseline (and identified a site’s weaknesses) with the initial report, you’ll have all the information necessary to take things to the next level.

    • says

      Hi Marcus,

      Can you be more specific? Are you looking for backlink data providers (e.g., OSE, Majestic, Ahrefs, etc.), or are you looking for a visualizer (e.g., Cognitive SEO’s Visual Link Explorer)?


  16. says

    Hey Steve,

    This is one fantastic list. I’ve heard of only a couple so I’m going to do some digging into your list. Will definitely try your own option here first, thanks!!


  17. says

    Wow, great list! I’ve tested my website with almost all of them to get advices or ideas about how to rank my website higher.

    Thanks for this post, really helpful for me :)

    • says

      Hi Henri,

      I’m really glad you like the list :-) Hopefully, these SEO analysis tools will help you improve your website’s optimization and ultimately your organic search traffic!


  18. Helen says

    Thanks Steve, that’s a really comprehensive overview!

    Especially I like how you mixed up well known tools everyone knows about (at least to me it seems everyone have checked HubSpot) and less obvious solutions, like SpyderMate (gonna have a closer look at it).

    As for my take, I’d like to point to WebSite Auditor website analysis tool. It could be on this list too, since there is a free version available (I’m using the paid one though).

    WebSite Auditor scans pages for code errors, duplicate content and other structure-related issues they may have. Other than that, there is this on-page optimization module, which allows determining the ideal keyword placement and researches page elements that can be optimized. In WebSite Auditor you can also analyze competitor’s pages to compare of to improve own on-page strategy. There are actually more features, I just won’t be listing all of them here. But this is the best solution with regard to on-page optimization I found so far.

    • says

      Hi Helen,

      Thanks for that very thoughtful comment. When I originally put this list of SEO analysis tools together, WebSite Auditor was on it. I don’t remember why it didn’t make the cut, but your comment fixes that oversight :-)

      Thanks again for commenting!


  19. Ellen L. says

    Cool insights Steve, thanks for the writeup !

    By the way, you could have included WebSite Auditor or Screaming Frog, without them the list doesn’t look complete somehow.

    However, I haven’t tried most of the tools so far, just played around with Woorank for a while, but 1 report per month wasn’t enough for me. Gonna have a closer look at some other solutions mentioned here.

    • says

      Hi Ellen,

      Thanks for mentioning those tools :-)

      As I mentioned in a previous comment, WebSite Auditor was mysteriously left off the list at the last minute. Fortunately, another commenter provided a nice description.

      Screaming Frog is great, and it appears in our free SEO tools post. I didn’t list it in this post because it’s so much more than just an SEO analysis tool.

      Thanks for the comment!


  20. Casey Lewis says

    Are these tools ranked? I was wondering which would be your number 1 choice. I want to outfit my sales team with a quality tool they can use to report on a bi-weekly basis to our customers.

    • says

      These SEO analysis tools aren’t explicitly ranked (although the first few in the list are probably the most popular).

      As for outfitting your sales team, it really depends on what type of reporting you’re interested in.

      These tools probably aren’t the best choice for bi-weekly monitoring… an analytics package would be better for that purpose.

  21. says

    I like two from this list i tested them all but these two were my favorite SEOpTimer and woorank mostly because they displayed results right away without trying to sell you something. I tested http://www.tjg-designs.com splash page and the results were right on.
    Thank you for the list it was fun testing each of these.

    • says

      Thanks Tommy! Those are both great SEO analysis tools… but I’m a little bummed that our tool didn’t crack your top 2. 😉

      Regardless, I’m glad you enjoyed the list, and thanks again for the comment.

  22. says

    Great list of SEO analysis tool. I think they are good to check your website stats and fix some issues to rank better than others, I mostly use woorank they provide some good sort of SEO analysis.

    • says

      Thanks Steve! WooRank is definitely a solid SEO analysis tool. And as you mentioned, you should regularly check your site for issues (and correct any that you find).

      It’s also important to note that most of these tools only scratch the surface — for a truly in-depth analysis of your site’s SEO, you’ll need to dig much deeper (on your own or with professional assistance).

  23. Alexandra Monroe says

    Hey Steve,
    Lovely article, thanks for the great software you linked. I’m also using advancedwebranking.com, the online software, and I found it to be a rather complete SEO solution.

    Thanks for sharing!

    • says

      Thanks for your kind words Alexandra! I looked into AWR for rank checking once upon a time, but I’ve never used it for other SEO analysis activities — I’ll have to give it another look.

  24. says

    Hi Steve,

    Thanks for this update and for including Raven Tools! We just added desktop and mobile page speed analysis to our Site Auditor, in case it’s been a while since you’ve taken Raven for a spin.

    • says

      Thanks for the comment Nicolette! I mentioned the desktop/mobile page speed analysis in the post — they both look great! Keep up the good work. :-)
