Write and validate Google Ads, Meta Ads, and LinkedIn Ads copy — with live split-screen previews that update as you type.
Ad Copy Character Counter is a free tool that helps you write, validate, and preview advertising copy for Google Ads, Meta Ads, and LinkedIn Ads — all against each network's exact character limits, with live mockups that show how your ad will really look.
Every field has a colour-coded counter that updates as you type and turns red the moment you exceed a limit, so you never paste an ad into the platform only to have it rejected or awkwardly truncated. A split-screen preview renders your headlines, descriptions, and call-to-action inside a realistic Google search result, Facebook feed card, or LinkedIn sponsored post, and a Mobile or Desktop toggle lets you check both placements. Marketers reach for it to:
Because everything runs in your browser, nothing you type is ever uploaded — draft confidential campaigns and unreleased offers with complete privacy. Built-in tips for each network remind you to lead with numbers, hook readers in the first few words, and match your CTA to the landing-page action.
Unlike guessing inside an ad platform's cramped editor, this tool gives you all three networks in one place with instant validation and a true-to-life preview, so you can copy finished, limit-safe ad copy straight into your account.
Google Responsive Search Ads allow up to 15 headlines (max 30 characters each), 4 descriptions (max 90 characters each), and two URL path fields (max 15 characters each). This tool validates the three most-used headline and two description slots.
Meta shows about 125 characters of primary text before a "See more" link on feed placements. Text beyond that is hidden until clicked. Write your hook and key message in the first 80–125 characters to ensure it's always visible.
"Shop Now" and "Learn More" drive the most clicks across most industries. "Sign Up" works well for lead generation. Match your CTA to the destination — if the landing page is a form, "Sign Up" or "Apply Now" sets clearer expectations than "Learn More".
High-converting ad copy leads with a clear benefit, speaks to one specific problem, and backs claims with concrete numbers — a price, a percentage, or a customer count. Add a single strong call to action and make sure the headline matches the landing page so the click delivers exactly what the ad promised.
Each Google Ads headline can be up to 30 characters. Shorter headlines that fit well below the limit are less likely to be truncated when Google combines them, so aim to make every word earn its place. Use the counter here to keep each headline punchy and within spec.
For Google Responsive Search Ads, write at least 8 to 10 headlines and 4 descriptions so the system can mix and match. For Meta and LinkedIn, test 3 to 5 distinct angles — such as a problem hook, a social-proof angle, and an offer-led version — then let the data show which message wins.
Yes. Everything you write here is your own copy — the tool only counts characters and previews how it looks, so you are free to use it in any paid campaign without restriction. Nothing is uploaded or stored, so your drafts stay completely private to you.
