Platform-specific copy rules
Google Search Ads — 30-char headlines (need 3 minimum, 15 max), 90-char descriptions (2 required, 4 max). Match keyword in headline. Generic 'Buy now' descriptions underperform; specific value props win.
Facebook & Instagram — Primary text up to 125 chars visible before 'see more'. Headline 27 chars, link description 27 chars. Lead with curiosity or specificity. Avoid words that trigger ad disapproval ('weight loss', 'guaranteed', 'free' in headline).
LinkedIn Sponsored — 150-char intro, 70-char headline, 600-char description for InMail. Professional tone wins; consumer language gets ignored.
The generator tunes character counts + tone per platform.
Headline patterns that convert
Four headline structures lift CTR 20-40% over generic. (1) Question — 'Tired of [problem]?'. (2) Specific number — 'Cut [metric] 47% in 14 days'. (3) Outcome promise — 'Hit $10K MRR without ads'. (4) Loss aversion — 'Stop losing [thing] to [problem]'.
Avoid: generic value props ('Best in class'), feature lists ('AI-powered, cloud-native'), brand name only ('Acme Inc.'). The generator outputs one variant per formula so you can A/B test.
CTAs that get clicks
Specific CTAs outperform generic ones consistently. 'Get my free SEO audit' beats 'Learn more'. 'Book your 15-min strategy call' beats 'Contact us'. 'Try free for 14 days' beats 'Start free trial'.
Three rules. (1) Use a verb that hints at low friction — 'try', 'get', 'see' beat 'submit', 'register', 'sign up'. (2) Include the value object in the CTA — 'audit', 'call', 'guide', not just 'click here'. (3) Match the CTA to landing-page promise — if the ad says 'free trial', the landing page must show a trial offer immediately, not a pricing page.
A/B testing ad copy
Run 3-5 ad variants simultaneously, not sequentially. Test one variable per test (just headline, or just CTA — not both). Let each test run until you have at least 100 clicks per variant before declaring a winner.
Most paid platforms (Google Ads, Meta Ads, LinkedIn Ads) include native A/B test features that auto-allocate budget to winning variants. Use them — manual budget split is harder and slower.
The generator outputs 5+ variants per generation specifically for A/B testing.
