The fastest free Google Ads preview tool and Responsive Search Ad mockup generator. Build a complete RSA — up to 15 headlines, 4 descriptions, sitelinks, callouts, prices, images, and call/location extensions — then preview it on desktop and mobile exactly as it will appear on Google search. No signup, no watermarks, no Google Ads account required.
The Google Ads preview tool (also called an ad preview tool, Google ad mockup generator, or RSA generator) is a free utility that lets you visualize a Google search ad before launching the campaign. You enter headlines, descriptions, a URL, and extensions — and the tool renders a pixel-accurate mockup of how the ad will appear on the Google search results page on both desktop and mobile devices.
This particular tool is built for Responsive Search Ads (RSAs) — Google's default ad format since 2022. It replaces Google's old Expanded Text Ad preview, the deprecated AdWords preview tool, and the anonymous Google Ad Preview & Diagnosis tool with a faster, more flexible, browser-based alternative.
A Responsive Search Ad (RSA) is the default text ad format in Google Ads. Instead of writing a single fixed headline, you give Google up to 15 headlines (30 characters each) and 4 descriptions (90 characters each), plus a final URL and an optional display path. Google's machine-learning system then mixes and matches your assets to assemble the best-performing combination for every individual search — by query, device, location, and audience signal.
That flexibility is also what makes RSAs hard to visualize. With 15 headlines and 4 descriptions, there are over 5,400 possible combinations. This free RSA preview tool helps you sanity-check the variations before they go live, so you don't waste clicks on awkward headline pairings or broken sitelinks.
Google retired Expanded Text Ads (ETAs) on June 30, 2022. New ETAs can no longer be created, and existing ETAs no longer serve. If you're searching for a Google AdWords preview tool, expanded text ad preview tool, or ETA mockup generator, you're in the right place — but the modern equivalent you actually need is an RSA preview tool.
Compared to the old ETA format, RSAs let you provide far more copy variations and rely on Google's machine learning to pick the best combination for each query. The headline character limit (30) and description limit (90) are the same as ETAs, but RSAs allow 15 headlines and 4 descriptions instead of the ETA's fixed 3 + 2. Use this tool to mock up the modern equivalent of any ETA you still have on file.
Enter your Final URL
This is where searchers land after clicking your ad. The favicon and display domain update automatically.
Set the display path
Add up to two short path segments (15 characters each) that hint at the landing page, e.g. /services/performance-marketing.
Write up to 15 headlines
Aim for at least 8–10 unique variations covering benefits, features, CTAs, and brand keywords. Stay under 30 characters each.
Write up to 4 descriptions
Each one is capped at 90 characters. Lead with benefits, then add proof points and a CTA.
Toggle ad extensions
Turn on sitelinks, callouts, structured snippets, prices, images, call extension, location extension, ratings, or promotions — exactly as you'd add them in Google Ads.
Preview on desktop and mobile
Switch tabs to see exactly how your RSA renders on each surface. The mobile preview mimics the real iPhone-style Google SERP.
Shuffle the headline combinations
Click Shuffle to simulate how Google rotates 3 of your headlines per impression.
Share or download
Copy a share link (it encodes every field, so your collaborator sees the exact same ad), or download a branded PNG for client decks.
Desktop and mobile renders match Google's real SERP, including favicon, "Sponsored" label, and extension layout.
Sitelinks, callouts, structured snippets, prices, images, call, location, promotions, and seller ratings — all toggleable.
Auto-rotates 3 random headlines every 4 seconds — just like Google's actual ad serving — so you see real-world combinations.
Pin specific headlines or descriptions to positions 1, 2, or 3 to test how Google will treat fixed assets.
Reorder headlines and descriptions with drag-and-drop to test different default orderings.
One-click share link encodes the entire ad — recipients see exactly what you see, no signup required.
Export a high-resolution branded screenshot of either preview for client approval or design decks.
Runs entirely in your browser. No login, no watermarks, no quotas, no Google Ads account required.
Google's official Anonymous Ad Preview & Diagnosis tool (sometimes searched as "ad preview anon" or "google anonymous ad preview tool") is meant for checking whether your live ad is appearing for a given query — without racking up impressions. It requires a Google Ads account and only works after your campaign is already running.
This Marketingly tool is the opposite: it's a pre-launch mockup generator. You don't need a Google Ads account, you don't need a live campaign, and you can test unlimited variations before you spend a single rupee. Think of it as the design-stage companion to Google's diagnosis tool.
Below are common scenarios where this Google Ads mockup generator saves time and budget:
A Responsive Search Ad is Google Ads' default text ad format. You provide up to 15 headlines and 4 descriptions, and Google's machine learning mixes them automatically to find the best-performing combination for every search query, device, and audience signal.
Yes — 100% free, no signup, no watermarks, and no usage limits. It runs entirely in your browser and works with or without a Google Ads account.
Up to 15 headlines (30 characters each) and 4 descriptions (90 characters each). Google shows up to 3 headlines and 2 descriptions per impression.
Yes. We render the favicon, "Sponsored" label, headline, display URL, description, sitelinks, callouts, structured snippets, prices, ratings, call, and location extensions to match Google's real desktop and mobile SERP layouts.
Yes — click Share to copy a link that encodes your entire ad configuration. Anyone who opens the link sees exactly the same preview. You can also download a branded PNG.
Ad Strength is Google's estimate of how well your RSA will perform. To improve it: add more unique headlines, include keywords, avoid pinning, write distinct descriptions, and enable extensions. Higher Ad Strength generally correlates with better ad rank and lower CPCs.
Headlines: 30 characters each. Descriptions: 90 characters each. Display paths: 15 characters per segment. Sitelinks, callouts, and structured snippet values: 25 characters each.
No. Everything stays in your browser. The only data we transmit is the favicon lookup for the domain you enter. When you click Share, the entire ad is compressed into the URL itself — nothing is stored on our servers.
Yes — use the Desktop / Mobile tab switcher above the preview. Each preview mirrors Google's real layout for that surface, including different truncation rules and extension placements.
No. Google's official Ad Preview & Diagnosis tool (the "anonymous ad preview tool") shows you whether your already-live ad appears for a given query — it requires a Google Ads account and a running campaign. Our tool is a pre-launch Google ad mockup generator: it lets you design and preview RSAs before they go live, with no account required.
ETAs were retired by Google on June 30, 2022 — you can no longer create or run them. The modern equivalent is the Responsive Search Ad (RSA), which uses the same headline (30) and description (90) character limits but allows up to 15 headlines and 4 descriptions. This tool helps you migrate any old ETA copy into the new RSA format.
Yes — "Google AdWords" was rebranded to "Google Ads" in 2018, but the search intent is identical. This tool previews modern Google Ads (Responsive Search Ads), which fully replaced the AdWords text ad formats.
Yes. Many agencies use the share link feature to build a library of RSA examples for onboarding new PPC managers, training clients, or pitching new copy variations. Every preview is shareable via a URL that encodes the entire ad configuration.
This tool is built for Google search ads (Responsive Search Ads). Display ads use a different format (Responsive Display Ads) with images, logos, and broader audiences — that's a separate tool.
