Writing within Google Ads' 90-character description limit
Google Ads description lines are capped at 90 characters, giving just enough room for a value proposition and a soft call to action. This tool generates description options built around common structures - feature plus benefit, urgency plus offer, trust signals - with your product worked in, and flags anything that runs past the limit so you can trim before pasting it into your campaign.
Why several description angles are generated at once
Google's Responsive Search Ads test different combinations of your headlines and descriptions automatically to find what performs best - having several genuinely different angles (urgency-driven, trust-driven, benefit-driven) to choose from gives that testing process more to work with than a single description repeated with minor wording changes.
Why the 90-character limit includes every character
Google Ads counts spaces, punctuation, and every visible character toward the 90-character cap - not just letters and numbers. A description that looks short at a glance can still run over if it uses a lot of punctuation or spacing, which is why the character counter checks the literal string length rather than just word count.
Why this uses fixed templates rather than AI-generated copy
These descriptions are assembled from proven, reusable ad-copy structures rather than generated freeform by a language model - a predictable, consistent starting point every time. Treat them as a fast first draft to personalize with your actual offer details, pricing, or promotions, rather than final copy ready to run unedited.
