warning MOBILE_AD_TEXT_SHORTER_THAN_TH

Mobile ad text shorter than three words (reason 63)

What this means

Microsoft Advertising requires that mobile ad text contain three or more words.

Why this happens

Microsoft Merchant Center validates titles against character limits, casing rules, and content policies — promotional language, all-caps, special characters, or keyword-stuffed titles are rejected.

How to fix it

  1. Trim title to the channel's character limit (most: 150–200 chars).
  2. Use Title Case — capitalize first letters of major words, not entire words. Remove ALL CAPS phrases.
  3. Remove promotional language: 'SALE', 'Best Quality', 'Free Shipping', 'Buy Now', etc.
  4. Format consistently: Brand + Model + Key Specs + Color/Size + Pack.
  5. Re-submit; title updates typically propagate within 1–4 hours.
