Google Ads character limits vary across ad formats, from Responsive Search Ads and Display ads to Performance Max and Demand Gen. Knowing how much text you can use for each headline, description, path, and asset helps you avoid formatting issues and write ads that are easier to read and more relevant to users. This guide breaks down the current Google Ads character limits and shows how to use that space more effectively.
Quick summary:
- Google Ads gives advertisers limited space to communicate, but the limit is not the same for every ad format.
- Responsive Search Ads allow up to 15 headlines and 4 descriptions, with character limits applied to each individual asset.
- Display, Performance Max, and Demand Gen ads use different limits for headlines, long headlines, descriptions, and business names.
- Ad assets such as sitelinks, callouts, and structured snippets have their own text limits.
- Staying within the limit is only the first step; strong ads also need clear messaging, relevant URLs, and copy that works well in different asset combinations.
Google Ads character limit elements
A typical Google Ads text ad consists of three primary elements:
- Headline
- Display URL
- Description
As a paid search marketer, adhering to the Google Ads length limit for your ad copy is essential. Mega Digital has developed a Google Ads character limit guide to assist you.
Headline
The headline text is what people will notice the most, so it’s essential to use words that match what people search for on Google. The google ad headline character limit is 30 characters, which is crucial for crafting concise and compelling messages to showcase your product or service. The headlines are separated by a vertical pipe (“|”) and may appear differently depending on the viewer’s device.
Display URL
The display URL, usually shown in green, displays your website address. It consists of the domain from your final URL and the text in the optional “Path” fields. These fields are intended to give viewers of your ad a clearer idea of where they will be directed when they click on it. The text in the path doesn’t have to be identical to the language used in the display URL.
Description
Responsive Search Ads allow advertisers to add up to 4 descriptions, with a maximum of 90 characters each. Google can combine different descriptions with your headlines and may show up to two descriptions depending on the search context and available ad space.
Special characters
Your ads support the correct display of most non-English characters, such as tildes (~), umlauts (ä, ö, ü), and cedillas (ç). This includes their appearance within the display URL.
Google Ads character limit for each ad type
Google Ads character limits vary across different ad formats, including Search ads, Display ads, Performance Max, Demand Gen, and Video ads. Understanding these limits helps you create ad copy that fits each format while keeping your message clear and effective.
| Ad format | Headline | Long headline | Description | Business name | Display URL path |
|---|---|---|---|---|---|
| Responsive Search Ads | 30 characters, up to 15 | – | 90 characters, up to 4 | – | 15 characters, up to 2 |
| Responsive Display Ads | 30 characters, up to 5 | 90 characters | 90 characters, up to 5 | 25 characters | – |
| Performance Max | 30 characters, up to 15 | 90 characters, up to 5 | 90 characters, up to 5 | 25 characters | 15 characters, up to 2 |
| Demand Gen image ads | 40 characters, up to 5 | – | 90 characters, up to 5 | 25 characters | – |
| Demand Gen video ads | 40 characters | 90 characters | 90 characters | 25 characters | – |
Google Search ads character limit
A Search ad can include a maximum of three headlines, two descriptions, and ad extensions. Depending on the viewer’s device, the third headline and second description may not be visible. However, including two headlines and one description in your search ad copy is highly recommended, without exception.
Responsive search ads
A responsive search ad looks like an expanded text ad to searchers. The difference is the ability to have multiple headlines and descriptions. Google uses machine learning to mix and match them for the best ad. Instead of making multiple text ads, create one responsive search ad and let Google create different versions. This helps save time and improve performance.
- Headline: 30 characters (up to 15)
- Description: 90 characters (up to 4)
- Display URL Path: 15 characters (up to 2)
Here are the differences between Expanded and Responsive ads:
Responsive Search Ads with call assets
Google is phasing out call-only ads. Since February 2026, advertisers can no longer create new call-only ads, and existing ones will stop receiving impressions in February 2027. Google now recommends using Responsive Search Ads with call assets to drive phone calls.
With this setup, you create a standard Responsive Search Ad and add your business phone number as a call asset. When the asset appears, users on call-capable devices can tap the call button directly, while desktop users may see a “Call us” option.
For the ad copy itself, the Responsive Search Ad limits still apply:
- Headline: 30 characters, up to 15
- Description: 90 characters, up to 4
- Display URL Path: 15 characters, up to 2
Ad assets
Ad assets add extra information to your Search ads, such as additional links, business highlights, product or service categories, phone numbers, and locations. They do not use the character space of your main headlines and descriptions, but each asset type has its own text limits. Google may show different combinations of assets when they are predicted to improve the ad experience.
Sitelink assets
Sitelink assets add clickable links that direct users to specific pages on your website, such as product categories, pricing, contact pages, or special offers.
- Sitelink text: 25 characters
- Description line 1: 35 characters
- Description line 2: 35 characters
Google recommends keeping sitelink text short and adding descriptions to give users more context about each destination.
Callout assets
Callout assets highlight short selling points or useful information such as “Free Shipping,” “24/7 Support,” or “No Setup Fee.” Unlike sitelinks, callouts are not clickable.
Callout text: 25 characters in most languages.
Structured snippet assets
Structured snippet assets highlight specific categories of products or services under predefined headers such as Types, Brands, Destinations, or Services. Unlike callouts, they should present a group of related offerings rather than promotional claims.
Structured snippet value: up to 25 characters in most languages.
Google recommends providing multiple relevant values under each header to give the system more options when serving your ad.
YouTube ads character limit
YouTube video ad text limits vary depending on the campaign subtype and ad format, so there is no single character limit that applies to every video ad.
For Video Reach campaigns using multi-format ads, the main text limits include:
- Call to action: 10 characters
- Short CTA headline: 15 characters
- Long headline: 90 characters
- Description: 90 characters
- Display URL: up to 255 characters
For non-skippable reach campaigns, advertisers can use a headline of up to 15 characters and a call to action of up to 10 characters.
Google is also moving Video Reach campaigns toward multi-format responsive ads, which can serve across in-stream, in-feed, and YouTube Shorts. This makes it more important to create headline and description assets that can work across different placements rather than writing for a single YouTube format.
Google Display ads text limit
Display ads have character limits that vary by format. Responsive display ads, Performance Max ads, and Demand gen ads offer visually appealing and personalized content. Therefore, it’s essential to create compelling and concise messaging to engage users effectively.
Responsive display ads
Submit your assets (images, headlines, logos, videos, and descriptions) for responsive display ads. Google will then generate ad combinations for websites, apps, YouTube, and Gmail. These responsive ads can be used in Display campaigns to maximize reach and engagement.
- Business name: 25 characters
- Headline: 30 characters
- Long headline: 90 characters
- Description: 90 characters
Performance Max ads
Performance Max campaigns use a mix of text, image, video, and other assets to create ads across Google inventory. For text assets, advertisers can provide multiple headline and description variations so Google can assemble different combinations based on the placement and user context.
- Headline: 30 characters, up to 15
- Long headline: 90 characters, up to 5
- Description: 90 characters, up to 5
- Business name: 25 characters
- Display URL path: 15 characters each, up to 2
Google currently recommends providing as many relevant assets as possible, with up to 15 headlines, 5 long headlines, and 5 descriptions available in a Performance Max asset group.
Demand Gen ads
Demand Gen ads help advertisers reach users across visual surfaces such as YouTube, Discover, Gmail, and the Google Display Network. Depending on the ad format, campaigns can combine images, videos, headlines, descriptions, and other creative assets.
For Demand Gen image ads, the main text limits are:
- Headline: 40 characters, up to 5
- Description: 90 characters, up to 5
- Business name: 25 characters
We recommend keeping at least one headline under 30 characters to give Google more flexibility when adapting your ad to different placements.
For Demand Gen video ads, text limits may vary by placement and format, but they can include a 40-character headline, a 90-character long headline, and a 90-character description.
What factors contribute to a winning Google text ad?
A successful Google text ad is affected by several key factors:
- Concise headlines
- Compelling description
- Relevant URLs
- Ad assets
Let Mega Digital show you more details about each of the factors.
Concise headlines
Creating concise headlines is a must when capturing users’ attention within the limited characters. Focus on using impactful and attention-grabbing words to convey the main message of your ad. By keeping headlines concise, you ensure that users can quickly understand what your ad offers.
Compelling description
Compelling descriptions play a vital role in persuading users to take action. Use the limited characters to highlight the unique features, benefits, or promotions of your product or service. Craft engaging and persuasive descriptions that create a sense of urgency or appeal to the users’ needs and desires.
Relevant URLs
A relevant URL provides clarity to users about where they will be directed when they click on the ad and builds trust and credibility. Ensure that the URL reflects the content or offer mentioned in the ad, making it more relevant and aligned with users’ expectations.
Path fields in Google Ads serve two essential purposes:
- Give prospects a clearer idea of where they’ll go when they click on the ad, building trust and increasing click-through rates.
- Allow you to match keywords to the user’s search query, further improving click-through rates.
Google provides up to two optional path fields, with a limit of 15 characters each. These paths are added to the display URL following your website’s domain. By utilizing path fields effectively, you can make your ads more relevant and appealing, resulting in higher click-through rates and improved ad performance.
In this example, the domain is “www.marketing360.com/“, and the path fields are “Doctor” and “Marketing.” These path fields are added to the display URL immediately after the domain.
Ad assets
When an advertiser adds an asset to a text ad, it can positively impact their Quality Score. Sitelink assets can boost Quality Score by 8%, resulting in increased ad exposure and lower cost-per-click. Ad assets, including sitelinks, provide more information and incentives for prospects, leading to higher click-through rates. Ad assets enhance user experience, improve ad performance, and drive better results in your campaigns.
Asset formats include: Sitelink, location, call, message, callout, price, promotion… However, whether or not Google Ads displays your assets depends on several factors: Ad Rank, Ad position, and other enabled assets.
FAQs about Google Ads character limit
Yes. Spaces count toward the character limit in Google Ads, so you should include them when checking whether a headline or description fits within the allowed length.
Google Ads will not accept text that exceeds the maximum length for that field. You’ll need to shorten the headline, description, path, or other asset before you can save or publish the ad.
No. You can provide up to 15 headlines and 4 descriptions, but Google selects different combinations when serving the ad. Up to three headlines can appear in the traditional headline position, while the number and placement of assets can vary by context.
The maximum field lengths generally remain the same, but Google counts characters differently for double-width languages such as Chinese, Japanese, and Korean. Each double-width character counts as two characters toward the limit.
Final words
In Google Ads, staying within the character limit is important, but using every available character is not always the goal. Strong ad copy should communicate the main message clearly while leaving Google enough flexibility to combine and adapt your assets across different placements.
If you need support creating or optimizing Google Ads campaigns, Mega Digital can help you improve your ad structure, messaging, and overall campaign performance.
