About this tool

How to use it

Choose your target digital ad platform: Google Ads (RSA), Facebook / Meta, LinkedIn, or Twitter / X.
Type or paste your marketing headlines, primary copy, and descriptions into the labeled input fields.
Monitor live character counters: green badges denote compliant lengths, while amber/red badges flag truncation risk.
Examine the real-time visual ad mockup preview to see exactly how your ad renders on mobile and desktop search feeds before exporting.

Why it matters

Exceeding ad platform character constraints results in awkward truncation ellipses ('...'), cutting off crucial calls-to-action (CTAs) and lowering Quality Scores. Writing directly within strict character constraints maximizes ad real estate, improves Click-Through Rates (CTR), and prevents ad disapproval delays.

When to use it

Use this tool during copy reviews, preparing ad copy decks for client sign-off, staging Google Responsive Search Ads (RSAs), or writing social paid acquisition creative.

Good to know

Google Ads allows up to 15 headlines (max 30 characters each) and 4 descriptions (max 90 characters each) per Responsive Search Ad. Meta recommends keeping primary feed text under 125 characters to prevent 'See More' truncation.

Common questions

What are the exact character limits for Google Responsive Search Ads (RSA)?

Google RSAs allow headlines up to 30 characters each, descriptions up to 90 characters each, and two URL display paths up to 15 characters each.

Why does Facebook truncate primary ad copy at 125 characters?

While Facebook allows up to 5,000 characters in primary text, feeds on mobile screens automatically truncate text past 125 characters behind a 'See More' button. Putting your core hook and value proposition in the first 125 characters ensures maximum visibility.

Do spaces and emojis count toward character limits?

Yes. Spaces, punctuation, and symbols count as 1 character. Modern emojis (like 🚀 or 🔥) typically count as 2 characters in UTF-16 strings used by ad management APIs.

Can I export all ad variants at once?

Yes. Click 'Copy Ad Spec' to format all current headlines, descriptions, paths, and character counts into a clean text block ready to paste into client decks or Google Ads Editor.
