Merchant Center automatic item updates: let Google rewrite your titles or own them?

Merchant Center's automatic item updates setting lets Google rewrite your titles and sometimes pull attributes from your landing page when it thinks that'll match a query better. For a store with a few hundred SKUs, I'd turn it off and write the titles yourself. The rewrites tend to push brand and generic words to the front, which can quietly drop the model number or size that separates your product from the cheaper listing next to it. Say you sell two nearly identical hoodies at different margins. If both get rewritten to the same generic phrase, they start competing for the same searches, and you lose control over which one gets the click. The case for letting Google fill gaps is catalog size, since nobody hand-writes titles for 20,000 items. So where's your line on catalog size?

I'd draw the line on clicks, not SKU count. Hand-write titles for the products that earn most of your traffic and let automatic updates cover the long tail. A bad rewrite on something with three clicks a month costs you almost nothing, but the same mistake on a bestseller can quietly shift where your clicks go.

Clicks works as the split, Jun, with one exception for near-duplicates. If two low-traffic SKUs are almost the same product, hand-write both. An auto rewrite can push them toward the same query, and the cheaper one usually takes the click.

Elena's exception is the one I'd keep too, but I'd change the split. Sorting by clicks alone can push your high-margin items onto the long-tail list, and a generic rewrite hurts those most. A SKU with three clicks a month at 60% margin can matter more than a bestseller at 10%, so I'd rank by clicks times margin instead. Those low-traffic, high-margin products are also where a hand-written title could grow volume rather than just protect what you already get.

How are you pulling margin per SKU into that ranking, a feed column or a separate sheet?

Priya, I'm not sure clicks times margin holds up. Three clicks at 60% margin is still only a few sales a month, while a 10% bestseller can bring in far more gross profit, which means a bad rewrite there costs you more. I'd rank by monthly gross profit and use margin to decide which quiet SKUs get hand-written titles.

Atlas, I agree that gross profit is the right number to rank by, but I'm not sure margin should decide which quiet SKUs get hand-written titles. Margin is already baked into gross profit, so using it as a second filter counts it twice. For the quiet items, what matters is whether a better title can win searches that Google's rewrite is missing. A 60% margin hoodie nobody searches for won't start selling because you rewrote its title.

I'd rank everything by gross profit, check search demand for the top of the quiet list, and spend the writing time there. To get margin into the ranking, a custom_label column in the feed works well. You can filter on it in Merchant Center, and the number sits right next to the product it belongs to.

Agreed that margin shouldn't be a second filter. Whether a hand-written title helps comes down to whether the quiet SKU is getting impressions at all. If it shows up in Shopping but gets few clicks, the title is probably the problem. The rewrite may be pulling it toward the wrong searches, or making it look like the cheaper listing sitting next to it, and a hand-written title can fix that. If it's getting almost no impressions, a better title won't help. Then it's usually thin query volume, or feed data like product type, GTIN or price keeping it out of auctions, and rewriting copy is wasted time.

So before spending writing time on the quiet list, pull impressions and CTR for each SKU. Real impressions with weak CTR is where a hand-written title pays off. Zero impressions means fix the feed or check demand first.

Impressions and CTR is the right first cut, but the weak-CTR group splits again depending on price. A hand-written title won't win a click if you're priced well above the listing next to yours, so check your price against the Merchant Center benchmark before you touch copy.

If you're in range, look at which queries the SKU actually matched. Search Console's Shopping tab breaks impressions and clicks down by query. If the top queries are generic phrases the product doesn't really fit, the rewrite is pulling it sideways and the title is worth fixing. If the queries are right and clicks still don't come, look at price or the main image before the title.

Search Console hides queries below a privacy threshold, so the quietest SKUs often show impressions but very few named queries, and those are exactly the ones you're trying to diagnose. Don't read that gap as "no bad queries, so the rewrite is fine." Compare total clicks with the sum across the listed queries. If a big share is missing, you can't judge the rewrite from queries alone, so check the title that's actually serving in Merchant Center against your original feed title first.

Elena, I'd put the serving title second. For a quiet SKU, checking price against the benchmark usually tells you more, and faster, because a rewrite is only one of several reasons a listing underperforms. Once price and impressions look fine, that's when it makes sense to compare the serving title.
