Google Standard Shopping gets traffic during learning, then drops to zero impressions

Hi everyone,

I’m running a Shopify store connected to Google Merchant Center through the Google & YouTube app, and I’m having a strange issue with Standard Shopping campaigns in Google Ads.

This has now happened twice with two separate Standard Shopping campaigns:

The campaign starts normally during the learning phase. I get impressions, clicks, and even a few sales. Product status looks fine, the campaign is eligible, and Merchant Center has around 2,600 approved products available for Shopping ads.

But as soon as the learning phase appears to be completed, the campaign basically flatlines.

For example, my latest Shopping campaign had:

318 clicks

32.1k impressions

average CPC around 1.38 SEK

439 SEK spent

a few sales during the active learning/testing period

Then, on the day after learning ended, it dropped to almost nothing

8 clicks

559 impressions

11.37 SEK spent

then basically 0 impressions for many hours

Google Ads says there are no problems showing the campaign. The campaign is active and eligible. Merchant Center also looks mostly fine, with roughly 2,000+ eligible products. There are some product issues, but most products are approved and available.

This exact same pattern happened with my first Standard Shopping campaign as well. It got traffic during the initial phase, then died after learning. That is why I temporarily switched to Performance Max, which does get traffic, but I would prefer Standard Shopping because I want more control.

I have tried different bidding approaches before, including Maximize Clicks with a max CPC limit, and manual CPC-style adjustments. The issue does not look like a simple bid setting problem, because the campaign gets impressions and clicks at first, then suddenly stops after the learning/initial phase.

Has anyone else seen this pattern with Standard Shopping campaigns?

Specifically:

Shopping campaign gets impressions/clicks/sales during learning

Learning ends

Campaign remains eligible

Products remain approved in Merchant Center

But impressions go completely flat

Could this be related to Merchant Center feed trust, product data quality, Shopify/Google app syncing, account history, product competitiveness, or something else?

Learning phase:

Learning phase ended (total flatline):

Any ideas on where to look next would be appreciated. I’ve attached screenshots showing the performance drop.

Thanks in advance!

Standard shopping should not have a learning phase, that is only with campaigns that uses AI, such as Performance Max, AI Max.

What you might be seeing is traffic increasing over time, which is not really a learning phase just a natural process of standard shopping campaigns, or other campaigns using non AI features.

Flat lining can mean a few things, the first and most obvious, you can’t expect a continues growth, there are thousands of other merchants competing for the same. And Google can’t show 1000 merchants in 1 search result.

So it balances this out, among all merchants, some merchants of course will get more traffic then others, based on ranking and bidding.

I recommend that you first focus on the data feed as that is the foundation of your ranking and potential traffic you get. You can improve this by adding and improving attributes, here is a list: Product data specification - Google Merchant Center Help

Then consider, if you can afford it, increase the budget and bids.

Finally some honest, really helpful non AI answers!

Love it @EmmanuelFlossie !

this is a frustratingly common issue with Standard Shopping campaigns. what’s usually happening is Google is testing your products during the learning phase, then once it has enough data, it decides your bids aren’t competitive enough for the auctions it was testing in, so it stops showing you entirely.

two things to try: first, check if your target ROAS or max CPC is too restrictive. during learning Google will spend freely but once it optimizes it might decide your targets are impossible to hit. try loosening your ROAS target or switching to maximize clicks for a week to force impressions back. second, check your product feed in Merchant Center for any new disapprovals or “limited” statuses that appeared after the learning phase ended. sometimes products get approved initially then flagged later.

Thank you so kindly Eligijus, on the community I never use AI, because community members can get AI answers already by just going to the AI tool, community members post here for human replies, honest, real feedback.

Thanks a lot everyone for the replies, I appreciate it.

That makes sense, it may simply be that Google tested the products initially and then decided the bids/product data/auction competitiveness were not strong enough to keep serving at the same level.

I also contacted Google Ads support, and their first reply mentioned that the account may currently be under an account-level security/policy review, which could temporarily limit impressions even if the campaign still shows as eligible. The reply looked AI-generated, so I’m taking it with some caution, but I have asked them to confirm whether such a review is actually active and whether it is limiting impressions.

They also mentioned a possible product group CPC issue, but in the Google Ads UI the product group shows “Automatic” bidding under Max CPC because the campaign uses maximize clicks with a CPC limit, so I’m waiting for them to clarify that part as well.

For now I’ll probably avoid making too many changes until Google confirms whether the account-level review is real.

Thanks guys.

Hey there @entranced,

This is actually a pretty common problem. During the learning phase, Google artificially pushes your impressions just to gather data, but once it ends, the algorithm becomes much stricter. If your traffic suddenly drops to zero, it usually means your feed data isn’t strong enough to maintain its rank against competitors, or if you’re running a Performance Max campaign simultaneously, that PMax campaign is likely cannibalizing all your Standard Shopping traffic.

To get things moving again, don’t just settle for your products saying “Approved” in the Merchant Center. You need rich data, so make sure things like GTINs, detailed attributes, and clear shipping policies are perfectly filled out. It’s also a great idea to disconnect and reconnect the Google & YouTube app in Shopify to force a fresh API sync. If you’re using Manual CPC, try bumping up your bids slightly just to kickstart those impressions again. Finally, double-check Google Search Console for any Schema markup errors, and make absolutely sure your website’s footer contact info matches your Merchant Center perfectly. Even a tiny mismatch can cause Google to quietly throttle your traffic for trust issues.

Hope this helps get your campaign back on track!

I would split this into two tracks so you do not end up changing the store when the real break is in Shopping delivery.

First, compare the products that got impressions and sales during learning against the rest of the feed. Look for category, price, margin, product title, image, availability, shipping, and policy differences. If the campaign flatlined after learning, Google may have decided it does not have a reliable pocket of products to keep serving.

Second, look at the landing pages for the products that did get clicks. If those pages have weak first-screen clarity, missing trust cues, unclear shipping/returns, or a CTA that is easy to miss on mobile, Google can still send early traffic but the system may not see enough conversion signal to keep scaling.

So my next check would be: are all 2,600 products being treated the same, or are there 10 to 30 products that had early traction and should be broken into their own test campaign? That would make the diagnosis much cleaner than restarting the same broad campaign again.
