Google Ads descriptions for Responsive Search Ads (RSAs) have a strict limit of 90 characters. Headlines have a limit of 30 characters, and display URL paths are limited to 15 characters each. Exceeding these limits will cause Google Ads to reject or truncate your ads.

You can add up to 4 descriptions to a single Responsive Search Ad (RSA). Google's machine learning algorithm tests combinations of up to 2 descriptions alongside 3 headlines simultaneously to determine which copy combination drives the highest Click-Through Rate (CTR) and conversion rate.

This tool supports proven direct-response frameworks including Feature-Advantage-Benefit (FAB), Problem-Agitate-Solve (PAS), Attention-Interest-Desire-Action (AIDA), Promotional/FOMO, Social Proof & Trust, and Direct Urgency & Call-to-Action (CTA).

Yes, 100%. All ad generation, character metering, and live simulation run entirely client-side in your web browser. No copy, brand names, or landing page URLs are transmitted to or stored on any server.

Use Alt+P for DevToys Smart Clipboard Auto-Detect, Alt+D to toggle Star Tool bookmarking, Alt+S to open the Developer API Studio, Alt+V to toggle between Split Studio and Stacked view, Alt+R for a random industry preset, Alt+1..6 for 1-Click Quick Copy formats, Alt+K or '?' for the shortcuts guide, and Esc to dismiss modals.

Pressing Alt+S or clicking 'API Studio' opens the Developer API Studio, offering instant, runnable Google Ads API code snippets across 5 languages (Python google-ads library, Node.js/TypeScript, cURL REST v17 mutate, PHP SDK, and JSON payload) with 1-click script downloads and real-time target export filename badge pills.

The built-in audit engine validates your copy against official Google Ads Editorial policies in real time: checking 90-character description caps, 30-character headline caps, keyword placement for ad relevance, prohibition of gimmicky all-caps words, absence of repetitive punctuation (no exclamation marks in headlines), and inclusion of intent-driven calls to action.

When you press Alt+P or click 'Paste Clipboard', the tool parses your clipboard content to automatically detect landing page URLs, root domain names, brand identifiers, and potential keywords or unique selling propositions (USPs), instantly pre-filling campaign fields for rapid RSA generation.

The tool encodes your entire campaign state (brand name, keywords, USP, selected tone, and custom headlines) into an in-browser URL hash fragment (#data=...). Because URL hashes are never sent across the network to web servers, you can safely bookmark or share the direct link with teammates while preserving 100% client-side privacy.
