Google picks which headlines and descriptions show, and how. A real ad can look different.
Paste a list of lines and they fill the fields below.
Sample shown. Type over it with yours.
5 of 15 headlines, 2 of 4 descriptions.

A responsive search ad takes up to 15 headlines of 30 characters and up to 4 descriptions of 90 characters, with a minimum of 3 headlines and 2 descriptions. Each of the two path fields takes 15 characters. Every character in Korean, Japanese or Chinese counts as two.
| Field | Limit |
|---|---|
| Headline3 to 15 per ad. Google Ads Help | 30 characters |
| Description2 to 4 per ad. Google Ads Help | 90 characters |
| Path 1 and Path 2Each. Google Ads Help | 15 characters |
| Sitelink text12 in double-width languages. Google Ads Help | 25 characters |
| Callout text12 in double-width languages. Google Ads Help | 25 characters |
This tool previews responsive search ads. Sitelink and callout limits are here for reference.
Google says up to 3 headlines can show in the headline position, picked from the ones you wrote. It tests combinations, so don’t write headlines that need each other to make sense. Pin text only if it must always show, because Google says pinning isn’t recommended for most advertisers.
The limits are the same across all languages, but every character in a double-width language like Korean, Japanese or Chinese counts as two. This counter follows that, so a 15-character Japanese headline already sits at the 30-character limit. Other languages count one for each character you type.
Your default text has to fit. Google says to keep it short enough for the limits, and lists too many characters as a common reason keyword insertion fails. This counter reads {keyword:default text} as its default text, so the count shows the version your ad falls back to.
Common reasons are repeated punctuation like “flowers!!”, emoji, decorative symbols, and spelling tricks like “fl@wers”. Editorial rules also cover capitals used for effect, extra spaces, repeated text and phone numbers in ad text. This tool flags the ones it can read from the text.
No. Google’s tool, inside your account, shows whether a live ad appears for a search. This one shows how an ad you’re still writing could look, with no account needed. Use this before launch, then use Google’s tool afterwards to check the ad is really serving.
Not exactly. Google picks which headlines and descriptions show, and changes the layout by device, query and assets. Treat this as a check on length and how lines read together. The preview inside Google Ads shows more once you build the ad there.
Good ads need clean conversion data behind them. Our Google Ads conversion tracking work sets that up at a fixed price.
