Collection of the 150 Best Free SEO Tools – 2019 Edition

This post has been updated on the 17th of January, 2019.

You might be a one-man band, a lean startup, or an SEO working within a marketing team. Either way, you understand the importance of a solid strategy and the right tools to do the heavy lifting. Of course, it makes it even easier if that tool is free! Below are 150 SEO tools that are either free or have free trials to pro versions you can check out before you buy. We found most free SEO resources online were generally outdated, contained broken links or recommended methods that have since been hit with Google penalties. We hope this collection of the 150 Best Free SEO Tools serves you well in your 2019 SEO efforts.

To get the most out of a free trial, there are a few things you should think about:

  • Make a plan beforehand for what you want to use the tool for and have your information prepared. Want to check on your competitors? Get a list of URLs together first. Most of the tools have export functions so make sure you extract all the data that you can before the end of your trial so that you can spend time analyzing it after.
  • Some of the tools which have free trials require payment information. Make sure that you set a reminder to consider whether you want to continue the subscription after the free trial has ended to avoid paying for a service you do not intend to carry on using.

A/B Testing and Conversion Rate Optimization

Much resources go into driving traffic to a website through SEO and other methods but Conversion Rate Optimization (CRO) is just as important, and A/B testing is the best way to measure and improve CRO. Are you enhancing the customer journey after they have clicked through to your site from Google?

Here are some of the best tools for A/B testing out there.

Crazy Egg

This tool allows you to see what users are doing on your site through heat maps. Crazy Egg is very limited in scope for testing, but it does have a simplistic interface that produces very easy to digest visual data. 30-day trials are available for all their price plans.

As Lucky Orange says, it’s like a DVR for your website, and it can be invaluable in examining why visitors are failing to convert.
