Our Extremely Large List of SEO Tools & Other Useful Resources

Evan Hall, SEO Strategist

I started working in SEO around 2009-2010, and over the past 12 years, I’ve encountered a lot of SEO tools. One of the biggest trends I’ve noticed is how there are fewer one-off tools. In the old days, you would use one tool to find all the broken links on a site, a second tool to find all of the images missing alt attributes, and a third tool to check the length of title and meta description tags. Now, Screaming Frog does all those things and more for only $209 per year, and it rocks!

While updating this blog post from its 2014 version, I checked every link to see if the tool still existed, and surprisingly, not many were still around. Tons of the tools were long retired, broken, or just plain not needed anymore.

The industry has matured a lot, and so have its tools. Instead of keeping long bookmark lists of free tools, gadgets, and browser bookmarklets, we now use a handful of go-to paid tools for most tasks. I think that’s a good thing. There are a lot of tools worth paying for these days.

So here’s our updated list of digital marketing tools for 2022. It’s based on the original list, what we use internally at Portent, and my experience with tools that have proven reliable over the years.

You’ll see some of the tools listed in multiple categories, and that’s because they do a lot. A couple of the tools included are direct competitors and basically do the same thing. For these instances, we don’t recommend using both. It’s best to look at each tool and see which one fits into your workflow or has a subjectively better interface.

Tools Save Time, Not Understanding

The best marketing tool you have is in your head. No amount of software, no matter how all-in-one it is, will perform the most important marketing task: thinking.

If you don’t understand what to do with the output of any of these tools, they won’t be very useful. The real strategy of SEO comes into play when you use the information from these tools to find the root cause of a problem and figure out a solution. This principle also holds when you’re communicating with other teams.

For example, SEO isn’t about asking a developer to fix lists of busted URLs. It’s about figuring out why there was a list of busted URLs in the first place and how you can work with a developer to prevent that from happening again in the future. If used properly, these tools will help you get to that stage of critically thinking a lot faster, which is all they can really do – save us time.

  1. David, you have been hiding your lights under a bushel. Thanks so much for sharing this wealth of information!

  2. Damn.
    That’s a whole boatload of tools and I stopped reading after the Competition Research and just started scrolling. I have a desire now to do a blog post where I use all of these tools for one site!
    Oh, but you missed a couple of my favorites:
    Raven Tools (Competitive, Link Building, Content and Reporting) http://raventools.com
    Beam Us Up (Research) Free unlimited site crawl toolhttp://beamusup.com
    Licecap (reporting) Free GIF screencap creation tool http://www.cockos.com/licecap/

    1. Thanks Jeremy – feel free to download the spreadsheet, I’ve got the entire list pivot-tabled with “slicers” so you can more easily search, find, sort, and generally have your way with the data. Be sure to ping me when/if you write that blog post!

  3. I thought I had the biggest list of tools but this is marvelously “insane”. The internet now is such a treasure trove of useful things. Have left my blogs for quite a while and its now time to ramp up again. These will keep me busy for months so a HUGE thank you.

  4. All these tools are great, but from a practical standpoint, how do you justify the investment?
    I’m guessing you don’t have subscriptions to all of them at the same time, but what advice would you give to in-house or agency marketers into preparing a business case for this investment, aside from a pithy “it will save you time” argument?
    Really interested in hearing your views on that as someone that has experience with a as wide a toolset as you do.

    1. I don’t have a one size fits all method for you or people in general to convince higher-ups that tools are worth the investment (note that many, many of the tools I shared are free) but one might consider tracking the time it takes to “go the long way” to get data, perform analyses (etc.) compared to the time saved when using a tool multiplied out across time and across clients / tasks as applicable – that way it’s not just “we’ll save time” but “we’ll save X time which translates to Y money saved compared to Z cost of tool”. Hope that helps!

  5. Awesome list!! Thank you for sharing. Another great (free) tool I’ve just recently discovered and begun using for keyword research is Soovle.com. It gives you the top searches for a number of search engines & eCommerce sites based on a keyword that you enter. Pretty interesting data and very fast way to build keyword lists.
    Thanks again!

    1. Thanks, glad you like the list! – Soovle is actually on the download file located at the end of the blog post, but editors had to cut some tools for space on the blog post itself… but thanks for stopping by and commenting!
