It's Not Google Being Stupid
When products show for wrong searches, the instinct is to blame Google's algorithm. "It doesn't understand my products." "The matching is broken." "Why would it show this?"
The uncomfortable truth: Google is doing exactly what your feed tells it to. The algorithm isn't stupid. It's literal.
Google doesn't know what you think you're selling. It only knows what your feed data says. If that data is vague, matching expands to fill the gaps.
This is actually good news. It means the problem is fixable. You don't need to wait for Google to "understand" your products better. You need to tell it more clearly.
How Google Interprets Titles, Descriptions, and Attributes
Google reads your feed hierarchically. Some fields matter more than others for query matching.
Product Title (Highest Weight)
The title is the primary signal for query matching. Words in your title directly determine which searches trigger your products. "Blue Dress" matches very different searches than "Navy Silk Midi Dress - Occasion Wear."
Description (Medium Weight)
Descriptions help Google understand product context and can influence matching for long-tail queries. They're secondary to titles but still read for relevance signals.
Attributes (Filtering + Matching)
Colour, size, material, pattern, and custom attributes help narrow matching. Missing attributes force Google to infer, and inferences expand matching to potentially wrong queries.
Google Product Category
Category tells Google what type of product you're selling and which auction pools are relevant. Wrong category means entering completely wrong auctions.
When these signals are vague, incomplete, or contradictory, Google does its best to match anyway. "Best" usually means expanding to include more searches, not fewer.
Real Examples You'll Recognise
These are patterns we see in feed audits every week:
Problem: Generic Title
Feed title: "Black T-Shirt"
Product: £85 premium merino wool crew neck
Appears for: "cheap black t-shirt," "black t shirt under £10," "basic black tee"
Fix: "Premium Merino Wool Crew Neck Sweater - Black | Luxury Knitwear"
Problem: Missing Material
Feed title: "Women's Summer Dress"
Product: £180 silk occasion dress
Appears for: "summer dress sale," "beach dress cheap," "casual summer dresses"
Fix: "Silk Midi Dress - Wedding Guest Occasion Wear | Navy"
Problem: Brand Without Context
Feed title: "Nike Trainers"
Product: £150 Nike React running shoe, men's
Appears for: "nike trainers sale," "cheap nike shoes," "nike trainers womens" (wrong gender)
Fix: "Nike React Infinity Run 4 - Men's Running Shoes | Black/White"
The pattern is consistent: vague data creates broad matching. Broad matching means appearing for searches where your price, quality, or product type doesn't fit what the searcher wants.
When Low CPC Is a Warning Sign, Not a Win
Here's a counterintuitive truth: low CPCs often indicate a feed problem, not efficient bidding.
The Low CPC Trap
When your products appear for low-intent, generic searches, CPCs are low because competition is low. Nobody with premium products is bidding on "cheap t-shirt" searches. But you are, because your feed makes you look like a cheap option.
Low CPCs with high volume and low conversion rate is the classic feed problem signature:
- •You're entering auctions where competitors with cheap products are bidding
- •The traffic expects cheap, sees your price, and bounces
- •You're paying little per click, but still wasting money on traffic that never converts
Higher CPCs in the right auctions beat lower CPCs in wrong auctions. Paying £1.50 for clicks that convert at 3% beats paying £0.30 for clicks that convert at 0.1%.
Early Indicators Your Feed Is the Problem
Catch feed problems before they compound into wasted spend:
Search Terms Report Shows Generic Queries
If your top search terms are broad category terms ("trainers," "dress," "skincare") rather than specific product terms, your feed isn't differentiating your products.
High Impressions, Low CTR
Your products are showing, but people aren't clicking. This often means the visual or price doesn't match what the searcher expected based on their query.
Price Modifiers in Search Terms
Searches containing "cheap," "sale," "discount," or "under £X" when you're selling premium products indicate your feed isn't communicating quality level.
Wrong Gender, Size, or Category Searches
Appearing for "women's" when you sell men's products, or for "kids" when you sell adult sizes, indicates missing or wrong attribute data.
The earlier you catch these signals, the less you waste. Every week spent fiddling with bids while the feed is broken is budget that could have been productive.
Frequently Asked Questions
Why do my products show for irrelevant searches on Google Shopping?
Google matches products to searches based on your feed data, primarily titles, descriptions, and attributes. If your feed data is vague or generic, Google expands matching to include searches that seem related but aren't actually relevant to what you sell.
How do product titles affect Google Shopping query matching?
Product titles are the primary signal Google uses to determine search relevance. A title like 'Black T-Shirt' will match any search containing those words, while 'Premium Merino Wool Crew Neck - Midnight Black' matches more specific, higher-intent searches.
Can I stop Google Shopping from showing my products for certain searches?
You can add negative keywords, but this treats symptoms rather than causes. The better solution is fixing your feed data so Google naturally matches your products to the right searches. Fix the source, and the wrong matches stop.
