The guide

What the google display ad campaign generator does, how to use it, and what to do with the result.

This display ad generator writes a launch-ready Google Display campaign plan from a short description of your business. You enter what you sell, who you want to reach and, if you like, a monthly budget in USD. You get back campaign settings, an audience plan with affinity, in-market, custom and remarketing segments, and responsive display ad copy: 5 headlines up to 30 characters, 1 long headline up to 90 characters and 5 descriptions up to 90 characters, each with its character count. It also adds image art direction, a placement exclusion starter list and a week 1 to week 4 optimization checklist.

How to Use the Google Display Ad Generator

Start with one clear sentence about your business and what you sell, for example "Bloom Bakery, a local bakery selling custom birthday cakes with same-day delivery". Then describe who you want to reach in plain words: age range, interests, the sites they read and whether you want past website visitors who did not buy. The more specific the audience, the better the segments and copy, because every line is written to that audience. Add a monthly budget if you have one, since the settings and the 4-week checklist are tied to it. Run the generator and read the plan top to bottom. Then open Google Ads, create a Display campaign, and enter the settings, audiences and ad assets yourself. The tool does not connect to your Google Ads account.

What the Display Campaign Plan Includes

The output follows six numbered parts. Campaign settings cover the bidding strategy, location and language targeting, a frequency cap, content exclusions and whether to turn on optimized targeting. The audience plan suggests affinity segments, in-market segments, custom segments with the exact keywords or URLs to build them from, and a remarketing setup with membership durations. Responsive display ad copy gives you 5 headlines, 1 long headline, 5 descriptions and a note on how to show your business name. Creative guidance describes what to put in the 1.91:1 landscape image, the 1:1 square image and the logo, written as notes a designer can follow. Then comes a placement exclusion starter list, a note on mobile app categories, and a week 1 to week 4 optimization checklist. The whole plan stays under 700 words.

Responsive Display Ads Specs: Headlines and Descriptions

A responsive display ad is the standard format in Google Display campaigns. You upload text and images, and Google mixes them to fit each placement across websites, apps and other inventory. The generator writes text to the limits you enter in Google Ads: short headlines of up to 30 characters, one long headline of up to 90 characters and descriptions of up to 90 characters. It gives you 5 headlines and 5 descriptions so Google has variety to test. Each line shows its character count next to it, which makes it quick to spot one that runs over before you paste it in. Count again anyway if you edit a line. A good headline carries one benefit, a good description adds a reason to act now, and both should still make sense when shown on their own.

Display Ad Examples for a Small Business

Here is the kind of copy the generator writes for a local bakery targeting parents planning birthday parties. Headlines: "Fresh Cakes Delivered Today" (27 characters) and "Birthday Cakes Baked to Order" (29). Long headline: "Custom Cakes Baked Fresh, Delivered Same Day" (44). Description: "Order by 2pm for same-day delivery across town." (47). Each line makes one promise and speaks to one audience. Notice what is missing: no stacked adjectives, no vague "best quality" claims, and no line that depends on another to make sense, since Google may show any headline with any description. For a software company the same rules apply, with lines about a trial offer, setup time or a single feature. Swap your own details into the inputs and the copy follows the audience you describe.

Common Google Display Campaign Mistakes

Display campaigns spend quickly when the setup is loose, and a few mistakes cause most of the waste. The first is targeting too broadly, such as an affinity segment alone with no custom or remarketing segments to anchor it. The second is skipping a frequency cap, so the same people see your ad again and again. The third is leaving placements open, which can send budget to mobile games and apps where clicks are accidental. That is why the plan includes a placement exclusion starter list and a note on excluding mobile app categories when lead quality matters. The fourth is uploading one headline and one image, which gives Google nothing to test. The fifth is judging results after two days. The week 1 to week 4 checklist sets when to review and what to change.

From Plan to Live Display Campaign

The generator writes the plan and the copy, so the next steps happen in your design tool and in Google Ads. Hand the creative guidance to a designer, or use it yourself, to make the 1.91:1 landscape image, the 1:1 square image and a logo, since this tool does not create images or banner mockups. Build the remarketing audience in Google Ads early, because lists need time to fill before they can serve. Enter the settings, then the segments, then the ad assets, and check every headline length in the ad preview before you publish. Make sure conversion tracking is in place so the bidding strategy has something to learn from. Then follow the weekly checklist: review placements, add exclusions, pause weak assets and shift budget toward the segments that convert.

What does the display ad generator create?

A Google Display campaign plan: campaign settings, an audience plan, responsive display ad copy with character counts, art direction for your images and logo, a placement exclusion starter list and a week 1 to week 4 optimization checklist.

Does it design banner images?

No. It writes the text and gives art direction notes for the 1.91:1 and 1:1 images and the logo, which a designer can follow. You create the images yourself or with your design tool, then upload them in Google Ads.

What is a responsive display ad?

It is the main ad format in Google Display campaigns. You supply several headlines, descriptions, images and a logo, and Google combines them automatically to fit different ad spaces on websites and apps, testing which combinations perform best.

How long can Google display ad headlines be?

Short headlines can be up to 30 characters, the long headline up to 90 characters and descriptions up to 90 characters. The generator writes 5 headlines, 1 long headline and 5 descriptions within those limits and marks each line's character count.

Do I need to connect my Google Ads account?

No. The generator works only from the business, audience and budget you type in. It never reads or changes your Google Ads account, so you review the plan and set up the campaign yourself.

How much does the display ad generator cost?

Each run costs 2 credits, and new accounts get 20 free credits. One run returns the full plan: settings, audiences, ad copy, creative notes, placement exclusions and the 4-week checklist. You need a Brainito account to use it.
