How to Optimize Google Shopping Ads?

A Shopping campaign has no keyword list. Google reads your product title and attributes and decides which searches you may compete for. So the title is what decides which auctions you are in at all.

Write it the way a customer types, not the way your warehouse labels it. "Aero X1" matches almost nothing. "Mens Lightweight Running Shoes Size 10 Blue" matches the way people actually search. Same shoe, same price, a completely different set of auctions.

Google knows what a product sells for. It does not know what it makes you. So a bidding strategy chasing revenue will happily pour budget into your worst-margin bestseller.

The fix is custom labels in Merchant Center: tag each SKU by margin and by how fast it sells, then bid, split and cap by those tags instead of by revenue. It is unglamorous, and on the accounts we run it is usually the change that moves profit fastest, because nothing else in the account knows margin by itself.

Read the search terms report weekly, not quarterly. Every term with real spend and no conversions is doing two kinds of damage: it burns cash, and it teaches an automated bid strategy that this kind of person is your customer.

The usual finds are research phrases ("how to clean", "instructions", "parts diagram"), the wrong size or model, and competitor names you cannot win against. Exclude them, then check that your brand searches are not being bought at full price when they were already yours for free.

Scaley AI does the second and third levers on repeat. It tags every SKU by margin and velocity and syncs those tags into your Merchant Center custom labels daily. Then it surfaces the search terms and products quietly burning budget. The first audit is read-only, every proposal carries the reason it was raised, and nothing is written until you approve it.

We build Scaley, so weigh that. The record behind it belongs to ZenoX Media, our sister Google Ads agency, which has generated €200M+ in revenue for 200+ ecom brands and is rated 4.8 from 38 verified client reviews on Trustpilot. Those are agency reviews, not Scaley product reviews.

Where something else wins. If your product data is wrong at the source, a feed management platform is the right buy, because that job is remapping and rewriting attributes rather than labelling them. DataFeedWatch calls itself a data feed management platform and says it connects to more than 2,000 channels and marketplaces. If you have an in-house PPC team that wants a rules workbench to drive itself, Optmyzr sells exactly that - its own pricing page leads on "Rule Engine Automations", priced by monthly ad spend from $25K upwards. Scaley has neither a rule builder nor a script library. And on a catalogue of a few dozen SKUs, an operator rewriting titles by hand for an afternoon will still beat any software.
