Google Responsive Search Ad Character Limits: 30, 90 and 15
Google responsive search ad character limits are 30 characters for each headline, 90 characters for each description and 15 characters for each of the 2 display path fields. You enter at least 3 and up to 15 headlines, and at least 2 and up to 4 descriptions, and Google shows up to 3 headlines at a time.

A responsive search ad is not one fixed ad. You give Google a set of headlines and descriptions, and Google Ads mixes them into different combinations for different searches. That makes the character limits easy to remember but the writing harder: every headline must fit 30 characters, and every one must make sense next to any other. This guide puts the limits from Google Ads Help in one table, then walks through writing a full set of assets that fits them, with an example and the rules on pinning, display paths and characters that count double.
| Field | Limit | How many you enter |
|---|---|---|
| Headline | Up to 30 characters each | At least 3, up to 15 |
| Description | Up to 90 characters each | At least 2, up to 4 |
| Display path | Up to 15 characters each | 2 path fields |
| Headlines shown at once | Up to 3 in the headline position | Chosen by Google Ads |
| Minimum shown per ad | 1 headline and 1 description | Chosen by Google Ads |
| Korean, Japanese or Chinese text | Each character counts as 2 | Applies to every field |
Google Responsive Search Ad Character Limits: 30, 90 and 15
List what the ad must say
Before writing, list the facts a searcher needs: the product, the main benefit, the price or offer, proof such as delivery or a guarantee, and the action you want. Each of these becomes one or more headlines. Writing from a list stops you repeating the same idea in 15 slightly different headlines.
Write 15 headlines of 30 characters or fewer
Google needs at least 3 headlines and accepts up to 15. Write each one so it stands on its own, because Google Ads can show any of them in any order, up to 3 at a time, separated by a vertical pipe. Mix keyword headlines, benefit headlines, offer headlines and call to action headlines, and keep each one under 30 characters.
Write 4 descriptions of 90 characters or fewer
You need at least 2 descriptions and can add up to 4. Each one has 90 characters, enough for one full sentence and a short call to action. Like headlines, they can show in any order, so do not start a description with words such as also or plus that depend on another line.
Fill both display paths
The display URL is made up of the domain from your final URL plus the 2 path fields, each up to 15 characters. Use them to show where the click goes, for example a category and a product type. Keep both paths true to the landing page.
Count every field before you upload
Paste each headline, description and path into a character counter. Spaces and punctuation count, and in Korean, Japanese or Chinese every character counts as 2. The free Google Ads Character Counter checks headlines against 30, descriptions against 90 and paths against 15, and the free Google Search Ad Preview shows how a combination looks on mobile and desktop.
Draft the set in Infinall AI
Save your brand once from your website, then ask Infinall Chat or the composers for headline and description options in your brand voice and check them in the counter. The paid ad composer in the Social Hub saves a Google ad as a draft on any plan, with up to 50 keywords per ad. Running it needs a connected ad account, which is a Pro feature, and Google bills the spend to your own ad account.
Why every headline has to work alone
Google Ads Help says assets can be shown in any order, so each one must make sense on its own or in combination, and must not break Google's policies or local law. In practice that means three rules. Do not split one sentence across two headlines. Do not repeat the same phrase in several headlines, because two of them may show side by side. And do not rely on a headline that only makes sense after another one, such as a line that starts with and.
A minimum of one headline and one description is selected for each ad, so your most important message should fit inside a single headline, not across three.
Pinning: when you need it and what it costs you
If some text must appear in every version of the ad, for example a legal line or your brand name, Google Ads Help says you must pin it to Headline position 1, Headline position 2 or Description position 1. Pinning gives you control, but it also cuts the number of combinations Google can test. Pin only what you have to, and if you pin a headline, write two or three options for that position so Google can still rotate between them.
Example: one offer as a full asset set
Say you sell handmade leather wallets with free delivery. Headlines under 30 characters could include: Handmade Leather Wallets, Free Delivery on All Orders, Slim Wallets for Every Pocket, Shop the New Collection, Gift Wrapping Available. Each one works next to any other. A description under 90 characters could be: Full grain leather, stitched by hand. Order today and get free delivery to your door. The 2 path fields could read wallets and leather, so the display URL shows the reader where they will land.
Read every pair of headlines aloud. If any pair sounds odd or repeats itself, rewrite one of them.
Editorial rules that trip up short headlines
With only 30 characters, it is tempting to write in capitals or squeeze in symbols. Google's editorial policy does not allow capitalization that is not used correctly or for its intended purpose, so a headline in all capitals for emphasis can be disapproved. Write in normal sentence or title case and let the words carry the message. Ads shown above the organic results already carry a Sponsored label, so you do not need to spend characters saying it is an ad.
Where Infinall AI helps, and where it does not
Infinall AI writes ad copy from your saved brand, so headlines and descriptions keep the same voice as your images and posts. It does not check every Google policy for you, so run the final text through the free counter and read it once more before you upload. Ad Spy lets you search the ads a brand is running on Google to see how others use their 30 characters. Infinall does not buy media: Google bills the ad spend to your own ad account. The Free plan gives 1,000 credits every month with no card; Pro costs $10 for the first month, then $30 a month or $299 a year, and is needed to connect ad accounts.
