How to Fix “Title exceeds maximum character limit” in TikTok Catalog

TikTok expects short, scannable titles. Long SEO titles built by concatenating brand, model, colour, size and keywords blow past the limit and get cut at an arbitrary character.

Why this happens

Technical root cause

Product titles in ecommerce catalogs are optimized for on-site search, not for a mobile feed. Exports pass them through unchanged, including bracketed marketing suffixes.

TikTok Catalog reports it as Title exceeds maximum character limit and applies: Title truncated mid-word or the row rejected on strict validation.

Native CMS friction

  • Shopify

    SEO apps rewrite titles with keyword suffixes that the product export carries into the feed.

  • VTEX

    The SKU name concatenates product name plus specification values, producing very long strings.

  • WooCommerce

    Variation titles append every attribute pair, e.g. “ – Blue, XL, Cotton”, on top of the parent name.

Fixing it manually

  1. 1

    Export the rejected rows and measure the character length of each title.

  2. 2

    Move keyword padding out of the title and into the description.

  3. 3

    Keep the pattern Brand + Product + key attribute at the front.

  4. 4

    Trim at a word boundary so the visible title still reads cleanly.

The IRONFEED automated solution

One rule, applied to every product on every export. No spreadsheets, no re-uploads.

Rule syntax
IF length(title) > 100
  SET title = truncate_words(title, 100)
  ELSE SET title = collapse_spaces(title)

Run automatic linter checks before TikTok Catalog crawls your feed. IRONFEED validates every export against the channel spec, so this error is caught in Feed Review instead of in your channel dashboard.

Frequently asked questions

Keep it at or under 100 characters; the front 40 do most of the work on mobile placements.

Only if the important words sit at the end. Order the title brand-first and truncation is harmless.

SKU ID cannot be empty

SKU is an optional merchandising field in most storefronts. Products created quickly, or imported in bulk, frequently have no SKU at all, and the export writes an empty cell rather than deriving an identifier.

Combinación de variantes no válida para la categoría

Store catalogs allow arbitrary option names such as material, flavour or pack size. Mercado Libre rejects axes its category does not define, and it also rejects two variants that resolve to the same combination.

Moneda no coincide con el site local de Mercado Libre

Regional sellers keep one base currency internally and expect conversion at publish time. The integration passes the base amount through, and locale formatting adds separators the API does not accept.
