What is the character limit for Google Ads descriptions?

Each description line has a max of 90 characters. Responsive search ads (RSA) use up to 4 description lines that Google combines automatically.

How does the description affect quality score?

Google rewards relevance between keywords, ad copy and landing page. Descriptions including the keyword and matching user intent create better alignment. The tool writes with this in mind, but quality score is set by Google and cannot be predicted in advance.

Can I use the copy in responsive search ads (RSA)?

Yes. The tool writes 4+ description lines intended to work in various combinations, as the RSA format requires.

Should I paste in the text from my landing page?

Yes, it gives better results. The tool does not fetch your page — it only sees what you paste in. With the landing page text available, the ad copy can mirror what is actually there.

How does this differ from Facebook Ad Headline Generator?

Google Ads descriptions must match search intent and include keywords. Facebook headlines must stop scrolling with emotional triggers. Completely different strategies.

What it does

Generates Google Ads copy adapted to the character limit, with emphasis on relevance and a clear call-to-action. You paste in keywords and text from the landing page.

Google Ads descriptions wasting your budget

Google Ads has strict character limits (90 characters per description) and rewards relevance with lower cost-per-click. Poorly written descriptions result in low quality score, higher CPC and fewer conversions.

90-character limit makes it difficult to communicate value and CTA effectively
Low quality score increases cost-per-click and reduces ad impressions
Descriptions not matching search intent produce high bounce rates
Manually writing 4+ description lines per ad group is time-consuming

Why use Google Ads Description Generator?

In Google Ads, you pay for every click — and the description determines whether that click converts. A description matching search intent, including the keyword and having a clear call-to-action is better positioned than generic copy. The tool writes with all three considerations in mind at once.

The real challenge is the 90-character limit. You must communicate value proposition, differentiation and call-to-action in under 90 characters — without sounding truncated or unnatural. The tool suggests compact phrasings that preserve the message, and states the length so you can verify it before publishing. For responsive search ads it writes 4+ lines intended to work together in various combinations.

For PPC specialists with many ad groups, the value is primarily a faster starting point. Instead of staring at an empty field for each keyword, you get variants to edit further. If you paste in the landing page text, the ad copy aligns better with what visitors actually meet — something Google values as relevance.
