Question

What’s the character limit for a single keyword in Google Ads?

Answer 1

Google Ads sets a hard limit of 80 characters per keyword. That includes letters, spaces, punctuation, and match type modifiers (like quotes for phrase match or brackets for exact match).

So technically, a keyword like:
"affordable personal injury lawyer near downtown los angeles california" has 72 characters, still valid.

But something like:
"affordable personal injury lawyer near downtown los angeles california who speaks spanish and offers free consultations" would be rejected because it exceeds the 80-character cap.

Why You Should Care

1. Keyword Quality Drops with Length
   Super long-tail keywords tend to underperform. They rarely match user queries, get low search volume, and don’t trigger ads consistently.

2. Split Instead of Stuffing
   Instead of writing one 100-character keyword, break it into multiple relevant shorter phrases. Google’s match types are smart enough to piece intent together — you don’t need full sentences.
   
   Example:

   • Bad: "best italian fine dining near marina bay sands singapore with rooftop view" (Too long)

   • Good:

     • "italian fine dining marina bay"

     • "rooftop restaurant singapore"

     • "best italian restaurant marina bay sands"

3. Don’t Copy Meta Descriptions into Keywords
   Some folks mistakenly paste long SEO content into the keyword list. Google Ads will not allow that. The keyword field is strictly for targeting phrases, not full statements.

4. Tools Will Flag It
   If you’re bulk uploading via Google Ads Editor or Sheets, anything beyond 80 characters per keyword line will throw an error. Always validate before uploading.

Action Tip:

If you’re unsure about a keyword’s length, paste it in a character counter tool before adding it. Also, regularly check your Google Ads interface for disapproved keywords — long keywords often get flagged silently if not monitored.
