A kitchen and bath contractor in Zionsville forwarded me his Google Ads account two Tuesdays ago. Call volume was down close to 40 percent for the second month running, right in the middle of his busiest season. Nothing in the dashboard explained why.

He runs one Performance Max campaign, about $2,400 a month, built around a handful of before-and-after renovation videos. His Search impressions barely moved. The rest of his budget, the part Google spreads across YouTube, Gmail, Discover, and the Play Store without ever telling you exactly how much lands where, had quietly thinned out.

On August 5, Google expanded a policy called Limited Ad Serving so it now covers all of Google Ads, not just the search results page. Until this month, an unverified or generically branded advertiser could lose impressions on certain search queries. Now the same check runs against every surface Google sells.

What Limited Ad Serving actually does

Google's own description is blunt: to protect the ad ecosystem, Google limits impressions of ads more likely to result in a bad experience. In these scenarios, only qualified advertisers serve ads without a cap.

Nothing gets rejected. No ad gets disapproved. Your account just stops showing up as often on the placements Google decided carry more risk, and Google gets to define "more risk" however it wants.

Google lists seven signals it weighs when deciding whether you qualify:

• Account attributes
• User activity and reports
• Account maturity
• Ad format usage
• History of policy compliance
• Advertiser industry
• Advertiser verification status

Read the last one twice. Verification is the one signal you can clear in an afternoon, and it is the one most small advertisers have never touched.

	Before June 2026	After June 2026	After August 5, 2026
Search	Unaffected	Impressions capped for unbranded ads on certain queries	Same, unchanged
YouTube	Unaffected	Unaffected	Now subject to the same qualification check
Gmail	Unaffected	Unaffected	Now subject to the same qualification check
Discover	Unaffected	Unaffected	Now subject to the same qualification check
Play Store	Unaffected	Unaffected	Now subject to the same qualification check

Google says the rollout will happen gradually and finish by 2028. It does not say when your account gets checked. That is the part that should bother you.

Does this touch you if you've never touched YouTube?

Probably yes, and that's the part most owners miss.

Performance Max is the default campaign type Google now pushes on new advertisers, and it does not let you turn placements on or off one at a time. You set a budget and some creative, and Google decides how much runs on Search versus YouTube versus Gmail versus Discover versus the Play Store, based on where it thinks your money performs best that week.

The contractor in Zionsville never opened a YouTube settings page in his life. He didn't need to. Google opened it for him the day he launched the campaign.

That means the August expansion widens the surface area of this policy without widening anything you have to opt into. You were already running on four or five placements. Now all of them check your verification status, your branding, and your account history the same way Search has since June.

Your budget still clears. It just spends less of itself where your customers actually are.

The fix is the one Google already told Search advertisers to do

Google's own guidance repeats across both updates, almost word for word:

1. Complete advertiser verification. It's free, it's inside your account settings if you're eligible, and Google names it as a direct qualification signal.
2. Put your business name in your ads. On Search, that means pinning your business name or domain to headline position 1. On YouTube and Discover, it means your video and image creative should show your actual name, not a generic offer.
3. Match the landing page. If your ad says Cardinal Kitchens, your landing page should say Cardinal Kitchens above the fold, not "Indiana's #1 Remodeling Experts."
4. Stay current on policy compliance. Old disapprovals and unresolved policy flags count against your account maturity score, even years later.

None of this costs money. All of it costs an afternoon, and none of it is optional anymore if more than one placement carries your budget.

What to actually check this week

Open Google Ads and go to Policy Manager. Look for anything mentioning limited ad serving. Google says advertisers with "a meaningful proportion of impressions in scope" get an in-account notification, and that word meaningful is doing a lot of unstated work. You may see nothing and still be affected.

Then open your Performance Max campaign and check the Insights tab for placement performance. It won't show you exactly how many impressions this policy cost you. Google doesn't publish that number to advertisers, and I'm not going to pretend I can back into it from the outside. What you can see is whether YouTube and Discover impressions dropped against a flat or growing budget, which is the closest thing to a symptom you'll get.

If your account gets flagged, the appeal runs through the Limited Ad Serving Appeals Form. Google says it will reinstate you once you qualify. It does not say how long that review takes.

At $2,400 a month and a rough $9 average cost per click across Performance Max, that contractor's budget buys around 266 clicks. If one in twelve of those clicks turns into a lead, that's 22 leads a month. Losing a fifth of your YouTube and Discover impressions without losing a dollar of spend doesn't lower the bill. It lowers what the bill buys, and the invoice never says so.

The contractor in Zionsville finished advertiser verification in eleven minutes once I walked him through it. His calls didn't bounce back the next day. They didn't bounce back the next week either. Whatever Google decided about his account, it's still deciding, and no dashboard is built to tell him when that's done.
