I previously blogged about 3 SEO tools that professionals might not know about and are absolutely free. Now I’m expanding my list and I’ll try to include more free SEO tools I use. If you have a startup company that invests more in digital marketing, you should definitely get these tools. Here are the reasons why:

  • startups usually have limited budget so they don’t hire an SEO agency
  • they usually have small or few projects
  • free tools are perfect for testing

I’ve tried plenty of free tools before and a lot of them are really interesting and helpful. But if you’ll ask me what my favorites are, they’re in this list. Check them out!

Keyword Research
