Ads that follow best-practice formatting see up to 25% higher CTR (Google, 2023). The Google Ads headline character limit is a technical requirement and a crucial foundation of ad performance.
Headlines are your brand’s first impression in search results, so they are an integral component of any pay-per-click (PPC) strategy. This guide covers headline limits, best practices, and proven formatting tips to help your ads stand out.
Google Ads allows advertisers to create text ads that appear on Google’s search results and display network. Such ads consist of a series of crucial components:
Although you can write three headlines (90 characters total), Google will not always display all three, especially on mobile. To be most effective, place your top priority messaging in Headline 1 and Headline 2.
Google Ads headlines are the first and typically the most crucial thing users see when your ad appears in search results. They play a massive role in how your ad performs by influencing:
If your headlines exceed Google’s 30-character limit, they can be shortened, which may result in incomplete messaging.
This can negatively impact readability, dilute your brand, and reduce conversion odds, ultimately affecting your campaign success and ROI.
Here is a brief overview of each component’s character limit in an average Google Search ad:
Tip: Although you may use the maximum character allowance, it does not necessarily follow that you should.
Briefer, punchier headlines often prove more effective by being quicker to read and more impactful, especially on mobile.
The best practices include:
1. Prioritize your value proposition early: Put the most important content (your USP, promo, or main keyword) in Headline 1 or 2 upfront so that it displays on all devices. Example:
2. Use power words and numbers: Terms like “free,” “now,” “limited,” and “save” create a sense of rush. Numbers, especially discounts or digits, directly capture attention. Example:
3. Use keywords strategically: Include your primary keyword in Headline 1 or 2 to match users’ search. This helps improve your Quality Score and makes your ad look more relevant.
Google may also use bold keywords in search results, making your ad stand out and attracting more clicks. Example:
4. Avoid repeating between headlines: Each headline must add value to your ad. Avoid repeating yourself, and avoid wasting character space. Example:
5. Test, test, test: Use Responsive Search Ads (RSAs) to test as many as 15 headlines, allowing Google to optimize for the most productive combinations.
However, make sure every headline is standalone and will be understandable in different combinations.
Even when your headlines are within 30 characters, they may still be shortened in specific actual display contexts. This is especially common on mobile devices, search engine result pages (SERPs) with lots of ad extensions displayed, or small placements such as Google Maps.
If headlines are shortened, key messaging is lost, which may lower engagement and suppress click-through rates. To lower this risk:
Here are some compelling headline examples that stay within character limits and encourage user action:
Before launching your ad campaign, use the following checklist:
The tips include:
Effective ads tell users what they want. Check your keyword’s intent: informational, transactional, or navigational, and craft headlines accordingly. Example:
While prohibited under Search Ads, emojis and special characters can be used in Display campaigns or Performance Max, which emphasize visual display.
DKI automatically inserts search words into your headline, adding relevance, but use them sparingly, not to create awkward phrasing or shortening.
Mapplinks collaborated with a U.S. fashion brand to optimize its online revenue through Google Ads. By writing headlines in an optimal 30-character limit for Google, they remained relevant and clear across all devices.
This strategic process led to a whopping increase in monthly revenue from $14,347 to $114,188 for 198 days. In addition, Return on Ad Spend (ROAS) also rose from 214% to 239%, while Cost Per Acquisition (CPA) decreased from $31.24 to $28.15.
This is an example of the impact of short, keyworded headlines in improving ad performance and ROI.
Writing a good Google Ad headline with tight character limits is intimidating, but it is a technique that can take your campaign to new heights. Only 30 characters per headline, and every word matters.
By keeping first the relevance of your keywords, the clarity of expression, emotional stimuli, and a call to action, not only do you adhere to Google’s formatting guidelines, but you are more likely to have more click-throughs, better Quality Scores, and ultimately, more ROI.
Keep testing headline combinations, stay updated on platform changes, and use features like ad previews to make your ads look great on every screen.
Do not forget: concise, pertinent, and deliberate headlines not only conform to Google Ads requirements; they are your key to capturing user interest in a crowded online environment.
No. Each headline field has a hard 30-character limit. Google Ads will not let you publish ads with longer headlines.
