**Answer.** There is no single winner in the data — the demo-vs-free-trial swap runs in both directions across 232 detected CTA experiments, where free-trial wording appears in 77 (33%) and demo paths in 25 (11%).[1] The recurring pattern is that product-led companies add a self-serve trial while shifting toward enterprise adds a demo escape hatch. Choose by buyer type, not by a universal best CTA.

> Free-trial wording appears in 33% of detected CTA experiments; demo paths in 11% — July 2026.

## Finding: the swap goes both ways

Across 232 CTA experiments, wording themes break down as (non-exclusive keyword incidence):[1]

| CTA theme | Count | Share of 232 |
|---|---|---|
| Free-trial wording | 77 | 33% |
| Price embedded in button | 53 | 23% |
| Demo path | 25 | 11% |
| Waitlist | 1 | <1% |

Demo-vs-free-trial swaps show up in both directions in the qualitative rows, so the data supports segmentation, not a fixed answer.

## Breakdown: two directions, two rationales

Detected CTA swaps illustrate each direction (observed change + inferred rationale, not measured lift):[2]

- **Toward self-serve — Cycle (web):** primary nav CTA 'Book a demo' changed to 'Start free trial.' Inferred rationale: moving from sales-led to product-led so self-serve teams experience value immediately.
- **Toward a sales path — Calendly (web):** added dual hero CTAs 'Sign up for free' (primary) + 'Get a demo' (secondary) where control had no in-hero CTA. Inferred rationale: the shift toward team/enterprise buyers means a segment needs a sales path a PLG-only control never surfaced.

## How to apply

Match the CTA to who converts. If you sell bottom-up to self-serve teams, the pattern favors a free-trial primary (Cycle's direction). If you are moving upmarket, the pattern favors pairing self-serve with a demo secondary rather than replacing it (Calendly's direction). All of these are observed changes with inferred rationale — validate with your own test before rolling out.

## Methodology

Universe: 232 detected CTA experiments, July 2026. Method: non-exclusive keyword incidence plus named-company qualitative rows. Caveat: demo-vs-trial swaps run both directions; all rows are observed changes with inferred rationale, not measured lift.
