Frequently asked questions

Is SignalForge really free?

Yes. Keyword research, SERP analysis, content briefs, site audits and the other tools are free with a free account, with daily fair-use limits (for example 100 keyword reports a day). No credit card is needed.

Where do the search volume and difficulty numbers come from?

Free numbers are modeled from public signals such as autocomplete data, result counts, Wikipedia pageviews and the strength of the ranking domains. Each metric is labeled in the interface, and the methodology page explains how it is computed. Real Google data is used only while a small daily data budget lasts.

Can I try it without signing up?

Yes. You get 3 preview reports a day without an account, and the free tools under /tools run in your browser with no signup at all.

What if I need licensed Google Ads volume, CPC or backlink data?

That is what SearchSignal Pro, our sister product, is for: Google Ads volume and CPC, licensed SERP data, live backlinks, 75-page audits and 2,000 searches a day for $19.99/month, usable from Cursor and Claude through MCP. SignalForge itself stays free.

Does SignalForge work with AI assistants?

Yes. Free accounts get a public API key and an MCP endpoint, so assistants such as Claude and Cursor can call SignalForge tools directly.
