The prompt we tested

You are an expert Google Ads copywriter specializing in Responsive Search Ads (RSA). Generate 15 unique, high-converting RSA headlines based on the product, service, or business described below.

Rules and formatting:
Each headline must be 30 characters or fewer (spaces included) and must not repeat the same phrasing twice. Include a strategic mix: 3 featuring the primary keyword, 3 highlighting benefits/USPs, 3 with a clear call-to-action, 3 with social proof or numbers, and 3 addressing pain points or urgency. Use Title Case, avoid excessive punctuation or ALL CAPS words, and comply with Google Ads policies (no misleading claims, no superlatives like 'best' without proof).

Business / Product / Service details:
We're a DTC mattress brand called DreamCloud selling hybrid memory foam mattresses with a 365-night trial and free shipping. Our target audience is adults 30-55 with back pain looking for better sleep. Starting price is $699 and we currently have a 40% off sale.

Output the 15 headlines as a numbered list. After the list, include a short 'Character counts' note confirming each headline is within the 30-character limit, and a 'Pinning suggestions' section recommending which headlines to pin to Position 1, 2, and 3.

## Pinning Suggestions

**Position 1 (Headline 1 – Keyword Focus):**
- #1 Hybrid Memory Foam Mattress
- #2 DreamCloud Hybrid Mattress
- #3 Memory Foam Mattress Sale

*Rationale:* Pinning keyword-rich headlines to Position 1 boosts Quality Score and ensures users immediately see relevance to their search query.

**Position 2 (Headline 2 – Benefits & Offer):**
- #8 Claim Your 40% Off Now
- #4 365-Night Home Trial
- #10 Mattresses From Just $699

*Rationale:* Position 2 is prime space for the strongest differentiators—price, promo, and trial period—to drive click-through.

**Position 3 (Headline 3 – CTA & Urgency):**
- #7 Shop Mattresses Today
- #15 40% Off Sale Ends Soon
- #9 Order Yours Risk-Free

*Rationale:* Closing the ad with a clear CTA or urgency cue increases conversion likelihood once interest is captured.

💡 **Tip:** Leave the remaining headlines unpinned so Google can dynamically test combinations and optimize performance over time.
Judge notes: The headlines are solid and well-structured, but several are generic and underwhelming for a premium DTC brand (e.g., "Shop Mattresses Today," "Order Yours Risk-Free," "Ease Back Pain Nightly" miss opportunities to be more specific, compelling, or differentiated), and the "1M+ Sleepers" social proof claim was fabricated without any basis in the provided business details.

## Pinning Suggestions

**Position 1 (Pin):** Headline #4 – *365-Night Risk-Free Trial*
- Addresses primary objection for mattress purchases; removes purchase friction for target demographic

**Position 2 (Pin):** Headline #8 – *Save 40% This Week*
- Creates urgency around current promotion; drives immediate action during sales window

**Position 3 (Pin):** Headline #7 – *Back Pain Relief Starts*
- Directly addresses primary pain point of target audience (adults 30-55 with back pain); highest relevance match
Judge notes: The headlines are functional and mostly well-categorized, but several are weak or incomplete-sounding ("Back Pain Relief Starts," "Free Shipping On Orders" feel unfinished), "Your Best Sleep Awaits" uses a superlative-adjacent claim, and "Trusted By Spine Doctors" is an unverified claim that could violate Google Ads policies—collectively enough issues to require edits before production use.

Judge notes: The headlines are functional but generic and repetitive (two nearly identical 365-night trial headlines, two 40%-off variants, duplicate price mentions), and the output fails to demonstrate the strategic category mix requested—several headlines don't clearly belong to their assigned group—making this serviceable but needing editing before production use.

**Character counts**: All headlines are 30 characters or fewer (ranging from 16 to 27 characters).  

**Pinning suggestions**:  
- Position 1: Headline 1 (DreamCloud Hybrid Mattress) – Strong primary keyword for relevance.  
- Position 2: Headline 4 (365-Night Home Trial) – Highlights key USP to build trust.  
- Position 3: Headline 7 (Shop DreamCloud Now) – Clear CTA to drive clicks.
Judge notes: Headlines are functional and technically compliant, but several are generic/weak (e.g., "Free Shipping Included," "Order Mattress Today"), the character count section lacks per-headline verification as requested, and the social proof entry "Join 1000s Sleeping Better" is vague and uncompelling for a production RSA campaign.
