Feed Forensics — Issue 02
Structure
Title structure drives match type and placement. Brand, product type, and attributes in the correct channel-specific order capture query patterns a copied store title never touches — and the first 70 characters do most of the work, because that's all many shoppers see.

Google Merchant Center title best practices
Search campaigns let you choose keywords. Shopping campaigns don’t. Google matches a product to a query from its product data, and the title is the field it weighs most. Google reads the title left to right, so the first words decide which auctions the product enters. Titles can run 150 characters, but many placements show about the first 70. Whatever sits in that window carries both the match and the click.
Most feeds inherit their titles from the product page, written for a shopper already on the site. Those titles often open with a collection name, a season code or an internal SKU, and push brand and product type further back. The attributes shoppers type, such as color, size, gender and material, land past the cutoff or never appear. One template often runs across every category, so a structure built for outerwear gets applied to footwear. None of this triggers a disapproval. The product serves against looser searches, and a competitor with a cleaner title takes the query you wanted.
Sharper adjectives rarely change which auctions a product enters. Reordering brand, product type and attributes does. The right order varies by vertical, so apparel, hard goods and consumables each need their own formula. Google also penalizes promotional text, all caps and keyword stuffing, so a longer title is not a better one. The deck lays out the formulas by vertical. It also shows where AI-assisted title generation fits inside a rules-based feed, so titles change across the catalog at once instead of one SKU at a time.

FAQ
The attributes your shoppers search by — typically brand and product type, then the differentiators (gender, keywords, color, size). Order varies by vertical; the deck breaks down the formulas.
The landing page must match what the ad claims, but the title text itself should be built for search, not navigation. Feed-level title rules let you restructure without touching store data.
No — Google penalizes it, and it degrades click quality. Structure beats volume: the right attributes in the right order.
