RSA Tips

→Write at least 5 unique headlines so Google has enough variation to test. Aim for all 15.
→Include your main keyword in at least 2–3 headlines. Pin headline 1 to a keyword headline if you want guaranteed placement.
→Each headline and description should make sense on its own - Google mixes and matches combinations.
→Use display paths to reinforce relevance. E.g. shoes › running signals the landing page topic.
→Include a clear call-to-action in at least one description: "Shop Now", "Get a Free Quote", "Book Today".

About Google Ads Preview Tool

The Google Ads Preview Tool lets you see exactly how your Responsive Search Ad will appear in Google Search results before you spend a single penny of budget. Enter your headlines, descriptions, and display URL, and the tool renders a pixel-accurate SERP mockup in both desktop and mobile views - so you can catch awkward truncation, weak copy, or missing calls-to-action before your campaign goes live.

Google Responsive Search Ads (RSAs) allow up to 15 headlines (30 characters each) and 4 descriptions (90 characters each). Google's machine learning then selects the best combination of up to 3 headlines and 2 descriptions for each auction. This tool enforces those exact limits: character counters turn red when you exceed a field's limit, and a warning banner reminds you that over-limit copy will be disapproved by Google before it ever reaches a searcher.

The display URL preview automatically extracts your domain from the Final URL field and lets you add up to two path fields (15 characters each) that appear as breadcrumbs after your domain - for example, example.com › products › sale. This helps signal relevance to searchers even before they click.

The Ad Strength meter scores your ad from Poor to Excellent based on how many headlines and descriptions you have filled in. A higher variety of unique messages gives Google's algorithm more to work with, leading to better auction performance. The tool gives you concrete guidance on what to add to reach each strength level.

When your ad is ready, the "Copy Ad Text" button exports all your headlines, descriptions, final URL, and display paths as a clean formatted text block - ready to paste directly into the Google Ads editor or share with a client for approval. No account is needed and nothing you type is ever sent to a server.
