The 30-character headline is the tightest constraint in mainstream marketing copy, and it is unforgiving. Write one character too many and Google Ads simply will not let you save the asset. Get everything to fit but waste the space on filler, and your ad blends into a search results page full of competitors saying the same thing. This guide lays out the Google Ads character limit for every field of a Responsive Search Ad, then walks through how to spend those characters so each one earns a click.
Responsive Search Ads are the standard search format, and their limits are the ones you will hit every day. You supply a pool of headlines and descriptions, and Google mixes and matches them per auction. The caps below are the commonly published figures as of 2026, and they count spaces and punctuation, not just letters.
| Field | Character limit (as of 2026) | How many you can add |
|---|---|---|
| Headline | 30 characters each | Up to 15 |
| Description | 90 characters each | Up to 4 |
| Display path | 15 characters each | 2 optional fields |
A few practical notes on that table. Google usually shows three headlines and two descriptions in a served ad, but never guarantees any single asset will appear, so no one headline can be load-bearing on its own. The two display path fields are cosmetic text appended to your visible URL — something like /free-trial — and they exist to reinforce relevance, not to carry your pitch. If you want the same limits for other platforms in one place, our word and character limits cheat sheet collects them across social, search, and applications.
Thirty characters is roughly four or five words. That is not enough room for a sentence, so stop thinking in sentences. Each headline is a claim, and the question for every word is whether it moves the reader toward the click. Three kinds of words consistently earn their place: action verbs that tell the reader what to do (Start, Book, Compare, Download), numbers that make a promise concrete (a price, a percentage off, a delivery window, a quantity), and the one unique thing you offer that a competitor cannot copy in their own headline.
Numbers deserve special mention because they punch above their character weight. "Free Shipping Over $50" is 22 characters and says something specific; "Great Value Shipping Deals" is longer, vaguer, and forgettable. Digits are shorter than the words that describe them and they signal precision, which reads as credibility. When you are deciding what to cut, keep the number and drop the adjective almost every time.
The mistake most people make is trying to write short from the first keystroke, which produces timid, generic copy. Write the full idea first, then compress. Here is the loop that works.
The discipline is in step three: you are choosing one idea per headline, not compressing three ideas into a smaller font. If two ideas both matter, they become two separate headlines, which is exactly what the 15-headline pool is for.
Because Google rotates your assets and learns which combinations perform, variety is not optional — it is how the system finds your winners. A useful way to fill 15 headlines without repeating yourself is to vary along a few axes deliberately. Write a few headlines that lead with the benefit, a few that lead with a number or price, a few that pose the searcher's question back to them, and a few that name the offer or brand. Do the same across your four descriptions, pairing a feature-led version with a proof-led one.
The catch is that each of those angles still has to survive the same 30-character cap, so you end up writing a long version of each idea and then shrinking it. Doing that fifteen times by hand is where the work piles up, and it is exactly where WordLimit earns its keep: you can hand it a longer headline draft and a target length, and it returns a version trimmed to fit while preserving the specific claim and your phrasing, so a whole set of variants stays consistent in voice instead of drifting as you hand-cut each one.
When a headline runs two characters over, the fix is almost never to delete an idea — it is to delete the dead weight surrounding it. A few patterns waste characters again and again.
Strip those four and most headlines that were three characters over come in under the cap with the actual message intact. For the general version of this skill beyond ad copy, our guide to reducing word count without losing meaning covers the same instincts applied to longer writing.
Ad copy is a near-perfect fit for a precise shortener because the target is a hard number and the penalty for missing it is a rejected asset. Rather than nudging a headline down one word at a time and re-counting, you can set the character target, keep the claim and voice you already wrote, and get a fitted version back. Do that across a batch of variants and your whole ad group stays on message while every field lands under its limit. When you are producing dozens of headlines a week, that is the difference between shipping campaigns and fighting a character counter.
Each Responsive Search Ad headline is capped at 30 characters as of 2026, and you can supply up to 15 headlines per ad. Spaces and punctuation count toward the 30, so plan for every keystroke rather than every letter.
Each Responsive Search Ad description allows up to 90 characters as of 2026, and you can provide up to 4 descriptions per ad. Google typically shows two of them at a time, so write each one to stand on its own.
Each of the two optional display path fields allows up to 15 characters as of 2026. The path is cosmetic and appended to your visible URL, so use it to reinforce relevance — a keyword or the offer — rather than to carry the main message.
Yes. Spaces, punctuation, and symbols all count against the character limit for headlines, descriptions, and paths. A 30-character headline is 30 keystrokes, not 30 letters, which is why the count is worth checking before you paste anything in.
Bookmark the limits above and write to them from the first draft. When a headline runs long, let WordLimit trim it to fit without flattening the claim that made it worth running.
