Google Popular Products vs. Popularity Rank: What Feeds Each One

A client's team recently sent us three good questions about Google's Popular Products section. They already knew it isn't a paid placement and that free product listings can put products there. What they wanted to know was whether their Merchant Center feed is what's doing it, whether Google could pull their products straight off the website instead, and what actually moves visibility. Somewhere in the same thread a Merchant Center help article on popularity rank came up, and that's where the two features got tangled together.

They come up together often enough that it's worth writing down. Below is what Google's own documentation says about each question, how we'd check the answer for a specific store, and the places where Google hasn't published an answer at all.

Two features with the same word in them

Popular Products is a place your products show up. Google's Search Central product documentation lists it among the shopping experiences in Google Search and describes it as a "visually rich presentation of products for sale." When Google opened these experiences to sites using Product structured data in 2022, it grouped Popular Products with the Shopping Knowledge Panel under what it calls merchant listing experiences, which are for web pages that let a shopper buy the product on the site.

Popularity rank is a piece of data you send. It's an optional product attribute, popularity_rank, holding a number from 0.0 to 100.0 that says how well a product sells compared with the rest of your own inventory. The first line of Google's spec says it's "primarily intended for use in conversational experiences such as AI Mode in Google Search."

Is your feed what puts your products there?

Possibly, and it may not be the only source. Google documents three routes product data can take into its shopping surfaces:

• Data you upload to Merchant Center: a feed file, a supplemental source, or the API. Google's guidance for larger or fast-changing catalogs is to upload feeds for more control over coverage and timing.
• Products Google finds for you: Merchant Center can add products automatically by scanning your site, reading the structured data on product pages, and filing the results under a "Found by Google" source. When the same product also lives in a source you uploaded, Google keeps your version and removes the automatic one.
• Crawled store content, with no Merchant Center involved: Google's free listings documentation says products crawled on your store can show up on Google "even if the information hasn't been marked up using schema.org or added in Merchant Center."

Google also warns that when it combines data from your website and your Merchant Center feeds, the two can fall out of sync, so blending them is a normal state of affairs. For a store with an active feed and marked-up product pages, the accurate answer to "which one feeds Popular Products" can easily be both.

You can't settle it for a particular store from the outside, and we wouldn't trust anyone who claims to without logging in. Here's the check we run inside the account:

1. In Merchant Center, open Marketing methods and look at the Free listings card. If free listings are off, the feed isn't what's showing products to shoppers for free, though crawled store content can still appear.
2. Go to Settings, then Data sources, then Product sources. Note every source listed and look for a "Found by Google" section, which holds anything Google added by crawling.
3. On the Performance page, filter results to free listings. That's where Google reports how the account's products perform without ad spend.
4. In Search Console, open the Merchant listings report under Shopping. It lists structured data errors, warnings, and valid pages for pages that sell products, which is the path Google uses when it reads your site directly.

Those four checks tell you which sources exist and whether each one is healthy, and that's the part you can act on.

Can products show without a Merchant Center feed?

Yes, and Google has said so in more than one place. The 2022 Search Central announcement says merchants "can be eligible for merchant listing experiences by providing product data on web pages without a Google Merchant Center account," and names Popular Products as one of those experiences. Merchant Center's help on automatic product sources says Google "uses structured data on your website to show basic product information in search results," and that "this happens automatically, even if you don't have a Google Merchant Center account."

Where a feed earns its keep is control. Google's Search Central guidance spells out what uploading product data adds over crawling:

• Coverage: "Web crawling is not guaranteed to find all products on your site."
• Timing: "Google does not guarantee how long it takes before changes on your site will be processed through crawling." A feed updates on the schedule you set.
• Data the site doesn't show: feeds can carry information you'd rather not publish, like store-level inventory.

Some surfaces need Merchant Center regardless. Google lists the Shopping tab as one of them.

For most stores we recommend the setup Google itself recommends: Product structured data on every product page plus a Merchant Center feed, with automatic updates switched on so Merchant Center corrects its copy of price and availability from your site when the two disagree. Google points smaller sites that change less often toward the crawl-built automated feed, and for a small catalog that's a sensible place to start.

What influences visibility in Popular Products

We haven't found a Google document that spells out how Popular Products chooses or orders its products. What Google does document falls into four areas, and they're the ones we'd work on.

• Eligibility: free listings have to be on, and products have to meet Google's free listings policies. Only product pages qualify, so home pages, category pages, and policy pages don't. In the United States and many other countries, Google requires shipping settings or a shipping attribute, and it recommends adding your return policy.
• Scope: Merchant Center's free listings page describes Popular Products as a visual carousel for apparel and accessories searches, available on mobile in the US. The Search Central documentation lists Popular Products among Search's shopping experiences without that qualifier and says the experiences change over time. Check the categories you sell in before assuming either way.
• Data quality and consistency: Google says the free listings setting "doesn't guarantee that your products will be shown," because it relies on the data you provide to match products with what shoppers search for. Complete titles, attributes, and identifiers give it more to match on. Keep the price and availability on your site identical to the feed, and give products strong identifiers (GTIN, or MPN plus brand), which Google specifically asks for in the Shopping Knowledge Panel.
• Relevance to the shopper: Google Shopping Help says products are "ranked based on relevance, as well as your search terms and other Google activity," and that results can be personalized from a shopper's searches, views, and saved preferences. That page covers Google Shopping results in general, so read it as Google's clearest public statement on how it orders products.

Money doesn't appear anywhere on that list. The same Shopping Help page says that unless a result is labeled "Sponsored" or "Ad," Google isn't compensated for clicks.

Where popularity rank actually fits

The attribute is optional and can be used in all countries. It takes a number from 0.0 to 100.0 with at most one decimal and no percent sign, and a higher value means the product sells better relative to the rest of your inventory. It has no schema.org equivalent, so it only travels through Merchant Center. Google's best practice is to update the value, for example through a supplemental data source, when a product's popularity changes substantially based on recent sales.

Go back to the first line of the spec: it's "primarily intended for use in conversational experiences such as AI Mode." We haven't seen Google connect it to Popular Products anywhere, so we wouldn't fill it in expecting a carousel spot. We'd fill it in for the reason Google gives, which is to communicate how well your products are selling, "like your latest best sellers," and help shoppers make a more informed buying decision.

It's also one of the easier conversational attributes to source honestly, because the input is your own sales data. In the five Merchant Center accounts we counted for our product feed optimization write-up, 2,576 of the 8,276 products our enrichment platform had published values to carried a popularity_rank. Google's minimum requirement is an accurate ranking, so derive it from real sales, refresh it on a schedule, and leave it blank before you'd guess.

Questions we get

Is Google Popular Products a paid placement? No. Popular Products is one of Google's free listing experiences. Google Shopping Help says that unless a result is labeled Sponsored or Ad, Google isn't compensated for clicks into Google Shopping results.

Do I need a Merchant Center feed to appear in Popular Products? No. In 2022 Google made merchant listing experiences, including Popular Products, available to sites that provide Product structured data without a Merchant Center account. A feed gives you more control over which products Google knows about and how quickly changes reach it, and Merchant Center is required for surfaces like the Shopping tab.

Does popularity rank affect Popular Products? Google hasn't said that it does. Its documentation describes popularity_rank as primarily intended for conversational experiences such as AI Mode in Google Search.

How can I tell whether Google is using my feed or my website? Check inside your accounts: the Free listings status under Marketing methods in Merchant Center, the list of product sources (including any Found by Google products), free listings performance on the Performance page, and the Merchant listings report in Search Console.

Where to start

If your team is asking the same three questions, open Merchant Center and Search Console before changing anything. Most of what decides Popular Products visibility is eligibility and data accuracy, and both show up in those two tools. If Merchant Center greets you with a long list of warnings, our breakdown of the alerts that actually block sales helps sort out which ones matter.

When the check turns up gaps, that's the work our Merchant Center enrichment service covers: clean feeds, structured data that matches them, and optional attributes filled from real data. Holler if you want a second set of eyes on your account.
