The 20 Best Free Chrome Extensions for Growth Marketers

Growth hacking tools are the bread and butter of growth hackers and digital marketers who want to make their life easier.

While there’s a huge number of such tools, we often forget about another set of tools that exist in our web browsers. Namely, Chrome extensions.

Many Chrome extensions are so useful that the value they offer is on par with stand-alone tools.

But there are so many! And let’s not forget how much RAM they take up. So we got to be selective. And a bit picky.

Hopefully, you will find this list of our favorite Chrome extensions useful. We split them into 4 categories: Development, Content/ Social Media, Email/ Lead Generation, SEO and Productivity.
