Google Ads ad preview: desktop and mobile mockup

Write your responsive search ad, track character limits field by field and see how it could look in Google results, on desktop and on mobile.

The tool previews your responsive search ad on desktop and mobile. It counts the characters of every headline (30), description (90) and display path (15), flags duplicates and checks that your keyword appears in at least one headline.

The tool needs JavaScript to run.

How to use it

  1. Enter the final URL and paths

    The final URL sets the domain shown in the ad. The two paths, 15 characters each, follow it and tell people what the page is about. They do not change the landing page.

  2. Write your headlines and descriptions

    Up to 15 headlines of 30 characters and 4 descriptions of 90 characters. The counter turns red as soon as a field runs over. To go faster, paste a list: each line fills one field.

  3. Add your target keyword

    The tool checks that it appears in at least one headline, ignoring case and accents, and tells you which one.

  4. Cycle through combinations

    The “Another combination” button changes the headlines and descriptions shown. Read every version: it has to make sense in any order.

How Google puts a responsive search ad together

A responsive search ad is not a fixed text. You provide up to 15 headlines and 4 descriptions, and each time the ad shows, Google picks which ones to display and in what order: up to 3 headlines and 2 descriptions. Google requires at least 3 headlines and 2 descriptions for a responsive search ad.

So every headline has to work on its own and next to any other. A headline that only makes sense in second position leads to clumsy combinations. You can pin a headline to position 1, 2 or 3, but each pin cuts the number of combinations Google can try.

Character limits to stay within

Spaces and punctuation count. Google Ads will not trim a field that is too long for you: you have to shorten it before you publish.

  • Headlines: 30 characters each, up to 15.
  • Descriptions: 90 characters each, up to 4.
  • Display paths: 15 characters each, up to 2.

Your keyword in the headlines

When searchers see their own search in a headline, they know right away that the ad answers it. Ad Strength, the rating Google Ads gives each responsive search ad, also suggests including your keywords in headlines and keeping headlines varied.

The tool spots the exact phrase, or its words in a different order. One or two headlines that echo the search are enough: use the rest for price, speed, service area or proof. To track what each ad brings in afterwards, build your links with the UTM builder.

A good ad does not fix a bad keyword

A well-written ad gets clicks. If the keyword behind it mostly attracts browsers, students or job seekers, the ad just makes you pay for them faster. Before you polish the copy, check that the search can lead to a sale: the keyword intent checker gives a first signal from the words of the query.

The best ad still pays for every click

Even a perfect ad pays for every click on the wrong keyword. Should I Bid reads the Google results page for each keyword before you pay, checks it against your offer and tells you: Bid, Test or Skip.

Frequently asked questions

How many headlines and descriptions does a responsive search ad need?

Google requires at least 3 headlines and 2 descriptions for a responsive search ad. You can add up to 15 and 4: the more you provide, the more combinations Google can try.

What is the character limit for a Google Ads headline?

30 characters, spaces included. A description can be up to 90 characters, and each of the two display paths up to 15.

Does the preview show exactly what searchers will see?

No, it is a guide. Google picks the headlines and descriptions itself based on the search, the device and the space available. It may show fewer of them or shorten them. Use the preview to check that every combination reads well.

Should every headline include the keyword?

No. Use it in one or two headlines and keep the others for your selling points. Fifteen headlines that repeat the same keyword look alike and give few truly different combinations.

What are display paths for?

They show after the domain (your domain › plumber › austin) and hint at what the page covers. They do not change the final URL: people still land on the page you entered.

Is my ad saved anywhere?

No. Everything happens in your browser: nothing is sent or stored.
