Open model · not frontier
This tester runs on Gemma 4 26B (Google), an open-weights model served by Cloudflare. It is not a frontier model like the paid versions of ChatGPT, Gemini or Claude: it is faster and more modest, and it will sometimes get things wrong. It shows how a good prompt behaves, not what the most advanced AI can do. Paste the prompt into your usual assistant for its best version.
Fill in the details and try the prompt with an open model without leaving the page.
Objective
Write headlines and descriptions for a responsive search ad.
When to use it
This prompt is ideal when you need to scale your campaign setup quickly without sacrificing relevance. It excels at generating high-volume ad assets that adhere to strict character constraints, ensuring your responsive search ads are ready for immediate deployment. However, it is less effective for highly nuanced brand storytelling where emotional resonance is more important than keyword density. Use it as a drafting tool to organise your initial assets, but always review the final output to ensure the tone aligns perfectly with your brand voice.
Worked example: input (fictional data)
Worked example: full response
Variants
Short and punchy
Focus only on generating 5 high-impact headlines and 2 descriptions. Prioritise urgency and punchy calls to action over descriptive content. Keep every line under 25 characters where possible to ensure they display fully on all mobile devices. The goal is maximum click-through rate, so be direct and compelling.
B2B Professional Tone
Adapt the tone for a corporate audience. Use professional, authoritative language rather than casual phrases. Emphasise reliability, efficiency, and compliance. Ensure the value proposition highlights time-saving benefits and operational excellence, as these are the key drivers for business clients looking for premium services.
Seasonal Promo focus
Inject a sense of seasonal urgency into the copy. Tailor the headlines and descriptions to highlight a limited-time offer or a specific seasonal need related to the service. Use words that create immediate interest, such as 'limited offer', 'seasonal savings', or 'exclusive deal', while still maintaining the character limits.
Common mistakes
- Not checking the character count: the AI sometimes gets it wrong.
- Claiming «the best» without evidence.
- Writing headlines that do not feature the primary keyword at all. How to avoid it: Ensure at least half of your headlines naturally integrate the core keyword to improve relevance scores.
- Using overly generic calls to action like 'click here'. How to avoid it: Always use specific, benefit-driven calls to action such as 'Book your clean' or 'Get your discount'.
- Failing to account for how headlines combine in responsive ads. How to avoid it: Write each headline to stand alone, so they still make sense in any possible random combination.
- Ignoring the landing page content when writing ad copy. How to avoid it: Verify that your ad copy promises exactly what the user will find upon clicking the link.

General and assistant-specific tips
Getting the most out of it
- Paste the prompt as is and only replace what is in [brackets].
- If the answer does not fit, do not start over: ask for “shorter”, “more formal” or “as a table”.
- Always review the result before using it: AI can get facts, dates or names wrong.
Before you paste it: quick checklist
- Don’t paste real customer data or full invoices.
- Describe your business in one sentence: trade, type of customer and area.
- Ask for gaps in [brackets] so you can fill in real data yourself.
- Check any tax or legal obligation on the relevant official website.
How to adapt it to your assistant
The template works the same in ChatGPT, Gemini, Copilot or Claude because it only uses plain language. If your assistant supports fixed instructions (custom instructions, Gems or projects), you can store your preferred tone and format there and paste only the variable part. On a free plan, split long requests into two or three shorter messages.
