Frequently Asked Questions
How many headlines can a Google Responsive Search Ad have?
You can add up to 15 headlines per Responsive Search Ad (RSA), but Google requires a minimum of 3. Google's AI automatically tests combinations and shows the best-performing mix. At any given time, up to 3 headlines are shown in a single ad.
What is the character limit for Google Ads headlines?
Each headline can be a maximum of 30 characters. Google counts characters based on the visible characters in the ad, not encoded characters. This tool shows a live character count and turns red when you exceed the limit.
What are display URL paths in Google Ads?
The display URL is what users see below the headline (in green/black text). It consists of your domain plus up to two optional path fields, each max 15 characters. Example: example.com/running/shoes. Paths don't need to match your actual URL — they're meant to reinforce relevance to the search query.
What is the character limit for Google Ads descriptions?
Each description can be up to 90 characters. You can add up to 4 descriptions in an RSA (minimum 2). Up to 2 descriptions are shown at once. Include a clear call to action and your key value proposition.
What makes an effective Google Ads headline?
The best headlines include the search keyword, a clear benefit, and/or a call to action. Pin one headline at position 1 with your brand or main keyword. Use the remaining slots to test benefits ('Save 50%'), social proof ('Trusted by 10,000+'), and urgency ('Limited Offer'). Avoid repeating the same messaging in all headlines.
