Frequently asked questions

What are the character limits for Google Ads?

Google Responsive Search Ads allow up to 30 characters per headline (up to 15 headlines can be entered) and up to 90 characters per description (up to 4 descriptions). Google Display Ads have a 25-character headline limit and a 90-character description limit. Google Performance Max assets follow RSA limits for text assets. These limits are checked and enforced by the Google Ads platform, but pre-checking before entry saves time and avoids copy being truncated without the writer's awareness.

What are the character limits for Meta Facebook and Instagram ads?

Meta advertising character recommendations vary by placement and format. For Feed ads, headline text is recommended at 40 characters or fewer, and body text at 125 characters or fewer, though Meta accepts longer text that may be truncated depending on placement. Story ads support shorter copy given the format constraints. Meta's character recommendations are guidelines rather than hard limits, but copy exceeding them is truncated in many placements, which can affect message clarity and performance.

Why do character limits vary by platform?

Character limits reflect each platform's interface design, audience behavior, and the context in which ads appear. Search ads like Google Ads operate in a text-dense environment where every character competes for attention, requiring tight copy discipline. Social feed ads appear alongside editorial content in formats where excessive text reduces visual impact and engagement. Short-form video platforms like TikTok use minimal text overlay because the video itself is the primary communication vehicle. Understanding why limits exist helps copywriters make better decisions within those constraints rather than treating them as arbitrary rules.
