Google Shopping Title Optimization: Bulk Title Pattern Builder

How to do Google Shopping title optimization in bulk

Google Shopping title optimization means writing each product title so shoppers see the right details first and Google can match it to searches. This builder rewrites every title in your feed from a pattern and checks the result against Google's Title [title] rules: the length limit, details first, no promotional text and a different title for every variant.

1. Add your feed. Use a Merchant Center export, a catalog file or any sheet with an ID and a title. Brand, color, size, material, gender and item_group_id columns give the patterns more to work with.
2. Check the columns. Headers are matched on their own. Map capacity, flavor or author to Other detail to use it.
3. Pick the platform and pattern. Keep one pattern per category, or write your own with parts like {brand} {title} - {color} - {size}. A part is skipped when the title already contains that word, so nothing is repeated.
4. Read the problems. See removed promo text, overlong titles, details hidden after character 70 and variants that share a title.
5. Download. Get the supplemental feed (id and title) and a review sheet with old and new titles.

Google Shopping title character limit and length

Merchant Center takes up to 150 characters, but shoppers usually take in only the first 70, so the start of the title must name the product. Meta allows 200 and recommends 65 (Meta's catalog specifications); TikTok and Pinterest allow 500. When a built title is too long, the builder drops the least useful parts first and keeps color, size and brand.

Product title formula for Google Shopping, by category

Google publishes one structure, for clothing: brand, then product type, then important attributes, with gender and age group when the photo doesn't make them clear (clothing best practices). The builder's patterns for electronics, beauty, home and other categories are our own starting points, not Google rules.

What to do next: put the new titles live

1. Review a sample. Open the review sheet and read twenty titles out loud. Each one should describe the exact product on its landing page, including the variant.
2. Upload as a supplemental source. In Merchant Center go to Settings > Data sources > Supplemental sources > Add supplemental product data. The tab appears after you add the Advanced data source management add-on under Settings > Add-ons. Choose the file, then link it to your primary data source.
3. Wait for processing. The supplemental title replaces the main title only for products with the same id. Check a few products afterwards to see the new title in their details.
4. Fix the source too. Change the product names in your shop over time, so a new feed app doesn't bring the old titles back.

Common Google Shopping title errors and fixes

“Additional or promotional info”

Merchant Center shows this issue when a title or description contains text such as “Free Shipping”, “Best Price Guarantee” or “30 Day Money Back Guarantee” (Google's fix page). Remove it and describe only the product. Words like “sale” or “clearance” are only flagged, because they can be part of a product name.

Google merchant center title too long

Over 150 characters, Google cuts the title and warns you. The cut can land mid-word or remove the size, so shorten it yourself and keep the facts.

Variants with the same title

Google asks for each variant's distinguishing details in its title, plus the matching color, size or age_group attribute. If variants differ by a detail the pattern lacks, the builder adds it at the end; variants that look identical in your file are listed.

AI-written titles sent as title

Titles written with generative AI belong in structured_title, not title. If you send both, Google uses title. This builder only rearranges your own data, so its output goes in title.
