Responsive search ad character limits: headlines, descriptions & paths

A Google Ads headline can be 30 characters long, including spaces, and every responsive search ad (RSA) needs at least 3 and at most 15 headlines. Descriptions can be 90 characters (at least 2, at most 4 per ad), and each of the two display path fields takes 15 characters.

The limits at a glance

Source: Google Ads Help — About responsive search ads and About text ads. The Google Ads API documentation confirms the minimums: at least 3 headlines, 2 descriptions and 1 final URL (Creating responsive search ads).

Two details catch people out:

• Double-width characters count twice. Google states that every character in a double-width language like Korean, Japanese or Chinese counts as 2 characters. A Japanese headline therefore holds 15 characters, not 30.
• Paths are display-only. Path 1 and Path 2 appear after your domain in the display URL (for example example.com/plumbing/emergency). They don't need to exist as real pages, but each segment is capped at 15.

For assets that sit under the ad, see the limits for sitelinks, callouts and structured snippets and other assets. All limits live on the Google Ads limits hub.

Do spaces count in Google Ads headlines?

Yes. Google's character counter in the ad editor counts every letter, number, space and punctuation mark as one character. There is no discount for spaces, hyphens, slashes or commas.

The first headline hits exactly 30: 26 letters, 3 spaces and 1 hyphen. Removing the spaces saves 4 characters but makes the ad unreadable. The last example fails by one character; dropping "Now" fixes it.

The same rule applies to descriptions. Licensed plumbers on call 24/7. Upfront pricing and no overtime fees. Book online today. is 88 characters and fits. Swap "and" for a comma and "today" for "in 2 minutes" and it grows to 92, over the 90 limit.

How many headlines Google actually shows

You can upload 15 headlines and 4 descriptions, but a single impression shows at most 3 headlines and 2 descriptions. Google's help page describes the fields as Headline 1 to 3 and Description 1 to 2:

• Headline 1 and Description 1 usually appear whenever the ad serves.
• Headline 2, Headline 3 and Description 2 may appear "based on what's predicted to perform best, or when there's enough space." They are not guaranteed.

That has two practical consequences:

1. Every headline must stand on its own. Google may show headline 7 next to headline 2. Don't write headlines that only make sense as a sequence.
2. Pinning costs flexibility. You can pin a headline to position 1, 2 or 3 (and a description to position 1 or 2). Google says pinning reduces the number of combinations that can be matched to a search, isn't recommended for most advertisers, and can affect Ad Strength. Pin only what legally or contractually must show, such as a disclaimer, and pin 2–3 alternatives to that slot instead of one.

Ad Strength rates the ad from Incomplete through Poor, Average and Good to Excellent. Google's guidance: provide as many headlines and descriptions as you can, keep them unique (no repeated words or ideas), include keyword text in headlines, and pin sparingly. A keyword only counts toward relevance if it fits entirely within one headline. Google reports that advertisers who move Ad Strength from Poor to Excellent see 15% more clicks and conversions on average. Source: About Ad Strength for responsive search ads.

Keyword insertion, countdowns & customizers

Dynamic text still has to fit the static limit, so plan for the longest value that could be inserted.

Working rules:

• Write the default text to fit on its own. Emergency Plumber is 17 characters, which leaves room for longer keywords. Google does not publish how the braces and syntax themselves are counted, so check the counter in the editor rather than counting the raw code.
• Reserve 8 characters for a countdown. Sale Ends in is 13 characters (with the trailing space), plus 8 for the countdown makes 21, safely under 30.
• Double-width text halves your room. A 12-character keyword in Japanese uses 24 of the 30 characters, before any static text.
