Create Effective Text Ads: Google Best Practices
Test and optimise creatives
Test and iterate your ad creative
You can learn about your users’ preferences and improve your performance by honing ad text, especially your headlines. Responsive search ads test across your different options for headlines automatically. Below are some tips to establish a testing framework for non-responsive ads that’s manageable and repeatable:
- Be organised. Use Google Ads labels. Something as simple as a calendar can help you to keep a schedule. Document start and end times.
- Establish a testing threshold and stick to it. Wait until you have served enough impressions to be confident in your results.
- Limit how many elements you test within your ads. Make different variations similar enough that you learn from their differences.
- You can stay on top of your ad testing in two ways:
- Campaign drafts and experiments help you measure your results to understand the impact of your changes before you apply them to a campaign.
- Implement three to five ads per ad group. The more ads that are present in an ad group, the more options you’ll have for success in an auction.
- Ad variations allow you to easily create and test variations of your ads across multiple campaigns or your entire account. For example, you can test how well your ads perform if you were to change your call to action from "Buy now" to "Buy today". Or you can test changing your headline to "Call Now for a Free Quote" across ads in multiple campaigns. Note that ad variations don’t yet work with responsive search ads.
- Learn what works for you, and keep track of the findings. Don’t repeat tests that you completed six months ago. Test with purpose. As they taught you in science at school: establish a hypothesis; prove or disprove that hypothesis; document results; test again.
Focus your testing efforts on high-value campaigns
It’s important to prioritise your testing efforts on the places that matter most. Think about areas of your account that drive a lot of volume or value for you. You can also focus on ad groups that would benefit the most from a new set of ad creative.
Optimise your ad rotation to prefer the best performing ads
Google Ads offers two different ad rotation settings:
- Rotate indefinitely
While there are use cases for each of the two options, the recommended approach is to optimise. Under this option, ads that are expected to attract more clicks (and conversions if you’re using a Smart Bidding strategy) are delivered more often into the ad auction than other ads in the ad group. Ads optimised to drive clicks can improve both your competitiveness and your bottom line.
If you choose to rotate indefinitely, it’s important to stay on top of your tests. Every impression that an underperforming ad receives is a missed opportunity, and those opportunities cost you money.
Ultimately, when you’re deciding the outcome of ad tests, you can use a combination of performance stats like CTR and conversion rate along with percentage served. Looking at CTR alone can be misleading. If the system is showing an ad more often than another, it can mean that it’s better at winning impressions in the auction itself, which is often a strong reason to prefer that creative over others.
Your ad text represents your brand to consumers who search on Google.com. It’s important to get the messaging right. Write ads that connect with people as they search.
