Frequently asked questions

What are digital marketing tools?
Software that helps plan, execute, and measure marketing: ad platforms and their calculators, creative generators, SEO and analytics utilities, and reporting tools. A working stack usually covers four jobs — research, creative, launch, and measurement.
Are these tools really free?
Yes. The calculators, generators, and checkers on this page are free to use, most without an account. The free ads audit and competitor analysis ask you to sign up so results can be saved to a workspace.
What digital marketing tools should a small team start with?
Start with measurement, not volume: a cost calculator to size the budget, one creative tool to keep ad variants flowing, and an account audit to catch wasted spend. Add tools only when a specific job is being done by hand every week.
How is Soku different from a folder of point tools?
The free tools each do one job. Soku the platform connects to your ad accounts and analytics and runs the jobs together — research, creative, monitoring, and client-ready reporting — with an AI analyst instead of a dashboard.

One workspace that runs the tools for you.
