AI Prompt for Google Ad for SaaS Free Trial

AI prompt for Google ad SaaS trial: intent-matched copy that attracts serious triallists, not freebie hunters. Free. Try it free in your favorite AI tool.

The prompt

You are a SaaS PPC copywriter who knows the difference between a click and a qualified trial.

CONTEXT: Software: [PRODUCT]. Category keywords: [KEYWORDS]. Ideal trial user: [IDEAL_USER]. Trial details: [TRIAL_DETAILS, e.g. 14 days, no credit card]. Core outcome: [CORE_OUTCOME]. Differentiator: [DIFFERENTIATOR]. Competitors buyers compare against: [COMPETITORS].

TASK: Write a Google responsive search ad promoting the free trial of [PRODUCT].

FORMAT:
1. 15 headlines (max 30 chars): 4 keyword-including, 4 trial-focused ("Free 14-Day Trial"), 3 outcome-focused, 2 differentiator, 2 competitor-alternative style ("Alternative to [X]" — only if [COMPETITORS] provided and policy-safe).
2. 4 descriptions (max 90 chars): 2 trial + outcome, 1 differentiator, 1 social proof.
3. Two sitelinks: Pricing and Features (25-char text + 35-char descriptions).
4. One caution note: which keywords would attract unqualified triallists, to add as negatives.

CONSTRAINTS:
- Trial terms must be exact per [TRIAL_DETAILS] — "free" claims get scrutinized.
- No "best" without proof. Competitor names only where policy allows.
- Speak to [IDEAL_USER], not everyone — specificity filters tire-kickers.
- Every line must survive random combination by Google.

Variables to fill in

Replace each [variable] in the prompt with your own details:

[PRODUCT] [KEYWORDS] [IDEAL_USER] [TRIAL_DETAILS] [CORE_OUTCOME] [DIFFERENTIATOR] [COMPETITORS]

Example input

PRODUCT='TidyBooks accounting', KEYWORDS='small business accounting software', IDEAL_USER='freelancers and agencies under 20 people', TRIAL_DETAILS='30 days free, no credit card required', CORE_OUTCOME='invoices paid 2x faster', DIFFERENTIATOR='built-in time tracking', COMPETITORS='QuickBooks'

How to use this prompt

Send trial ad traffic to a trial signup page, not your homepage — message match lifts trial starts. Track trial-to-paid conversion by keyword, not just cost per trial.

Tips for the best results

'No credit card required' in a headline can double trial starts for the right audience.
Bid on competitor-alternative keywords only with a comparison landing page.
Add 'free' as a negative where it attracts the wrong intent (e.g. 'free accounting software').
