Frequently Asked Questions

What are UTM parameters and why do I need them?

UTM (Urchin Tracking Module) parameters are tags added to URLs that tell Google Analytics where your traffic came from. They track source, medium, and campaign name so you can measure which marketing channels drive the most conversions.

How does the AI ad copy generator work?

Select your ad platform, enter your product details and target audience, and AI generates 3 ad copy variants using different persuasion angles (pain point, benefit-first, social proof) — all optimized for your platform's character limits.

How long should I run an A/B test?

It depends on your traffic and the size of the effect you want to detect. Our A/B Test Calculator computes the exact sample size and duration based on your conversion rate, traffic, and desired statistical significance.

Are these marketing tools really free?

Yes. Every tool is 100% free with no signup, no account, and no hidden limits. AI-powered tools have per-session generation limits to manage API costs, but you can always start a new session.
