Frequently Asked Questions
What are the Facebook Ads character limits?
Facebook Ads have the following limits: Primary Text - 125 characters recommended (500 max before truncation), Headline - 40 characters recommended (255 max), and Description - 30 characters recommended (125 max). Text beyond recommended limits may be truncated on some placements.
What are the TikTok Ads character limits?
TikTok Ads allow up to 100 characters recommended (150 max) for ad text and 80 characters max for the display name. TikTok is a mobile-first platform, so shorter, punchier copy tends to perform better.
What are the Google Ads character limits?
Google Search Ads (Responsive Search Ads) allow: Headlines - up to 30 characters each (you can add up to 15 headlines), Descriptions - up to 90 characters each (up to 4 descriptions), and Display Path - 15 characters per path field (2 path fields).
Why is ALL CAPS flagged as a warning?
Text in ALL CAPS can appear aggressive or spammy to users and may violate platform advertising policies. Both Facebook and Google have policies against excessive capitalization. Using sentence case or title case is recommended for better engagement.
