Notes
In Standard Shopping, your product title is your keyword
In a Search campaign you pick keywords, and those keywords decide which searches your ad can show on. Standard Shopping has no keyword field. You never tell Google which searches to compete for. It reads your product feed and decides for you, and the single biggest input it reads is the product title. Your title is your keyword, whether you treat it like one or not.
Shopping matches on the feed, not on keywords
There is nowhere in a Standard Shopping campaign to type a keyword. Google works out relevance from the feed: the product title, the product type and category, the attributes, the description, and the landing page. The title carries most of the weight. In practice the title, and the exact words you put in it, account for the large majority of the searches you end up showing on. Get it right and you show on the right searches. Leave it vague and Google guesses, usually wrong.
Your title is the keyword, so write it like one
A good Shopping title is a composite, not a brand slogan. Lead with what the product is and the words a buyer would search, then layer the attributes that qualify it: size, color, material, key feature. Brand goes last, unless your brand is itself what people search for.
A backpack titled Backpack tells Google almost nothing. The same product titled 50L Hiking Backpack Grey Waterproof Nylon Adjustable Strap | YourBrand tells it exactly what to match, in roughly the words a buyer would type. Aim for around 70 characters, and order matters: the front of the title carries the most weight, so put your strongest commercial term first.
A word of restraint: this is not a license to stuff. Cramming in attributes you do not really sell on, or padding the title to catch more searches, pulls in junk traffic and dilutes how relevant Google thinks you are. Structure and accuracy beat length.
A flood of junk search terms is a feed problem
Here is the reframe that saves the most wasted spend. When a Standard Shopping campaign shows up on a pile of irrelevant searches, the instinct is to treat it like a Search campaign: add negative keywords, cut bids, fight it query by query. That treats the symptom. With Shopping, a stream of irrelevant search terms almost always means the title is telling Google the wrong thing about the product. Read your search terms report as a diagnostic of your titles, not just a list to negate. Fix the title and most of the junk disappears at the source.
How to fix it
Start with the title, before you touch a single bid or negative.
- Rewrite the title as a composite. Strongest search term and product name first, then the qualifying attributes, brand last. Around 70 characters.
- Use the search terms report to debug the title. Irrelevant terms tell you which words are misleading Google. Adjust the title rather than burying the symptom under negatives.
- Test the order. Move your best commercial term to the front and measure the change in search terms and conversion rate.
- Then clean the edges. Now negatives and bid work do their small job, and splitting campaigns by product category makes the feed work pay off group by group.
In Search you buy keywords. In Shopping you write them into the title. Treat the feed as the campaign, because to Google, that is exactly what it is.
