Reset your Google bid targets this week before the free lunch ends

Google's Smart Bidding shift on August 17 will pull overperforming campaigns back toward their stated targets. This issue covers that plus four other paid media changes that need action before the next campaign flight.

Google Smart Bidding stops overdelivering on August 17

Google confirmed that budget-limited campaigns using Target CPA or Target ROAS will begin delivering more consistently toward their stated bid target starting August 17, 2026. Google's own example: if your Target CPA is set to ten dollars but your recent actual CPA is five dollars, the campaign will start delivering closer to a ten dollar actual CPA. The change covers Search, Shopping, Performance Max, Demand Gen, Travel, Search Ads 360, and Demand Gen in Display and Video 360. Google will not adjust your targets or budgets automatically.

This hits any lean team or fractional operator running Google Ads on a capped daily budget where the account has been quietly overperforming its targets. If you set a Target CPA six months ago and never revisited it, your campaign will deliver closer to that stale number.

The move this week, under an hour: filter Google Ads to campaigns with status Limited by budget and bid strategy Target CPA or Target ROAS. For each one, compare the current target to the trailing 30 day actual. Either lower the Target CPA (or raise the Target ROAS) to reflect real performance, or switch to Maximize conversions or Maximize conversion value if you want to hold spend flat within budget. Google has published a Bid Target Adjustment Tool to help scope the affected campaigns.

Travel campaigns will be auto-migrated in Q3, or you can do it yourself

Google will start migrating existing Travel campaigns to the new Search campaigns for Travel in Q3 2026. There is no fixed date; Google says exact timing will arrive by email and in-account notification. Auto-migrated campaigns will be replaced with new Search campaigns for Travel that mirror the closest equivalent settings from the original. Advertisers can also migrate manually before their scheduled date.

This hits hotels, tour operators, OTA affiliates, and any agency running Travel campaign types. Auto-migrated campaigns will preserve what Google considers equivalent, which is not the same as preserving what you built. Custom bid strategies, ad copy, and audience settings are the usual casualties in a mirror migration.

The move this week: pick one live Travel campaign, screenshot every settings tab and export the current ad copy and audience settings, then run the manual migration on that campaign so you can compare the new structure against your notes. Once you know what the mirror actually preserves and what it drops, migrate the rest on your own schedule instead of Google's.

Performance Max adds a local customer toggle for store-goal campaigns

Google published a new help document today describing Local customer optimization inside Performance Max campaigns with store goals. When enabled, PMax will prioritize delivery to users who are nearby and actively planning trips, navigating, or searching for local businesses across Google Maps, Waze, and local formats on Google Search. The setting lives under Budget and bidding optimization inside campaign settings. Important limitation: Local customer optimization is not compatible with Merchant Center, so retailers running product feeds through PMax cannot use it.

This hits multi-location service businesses, clinics, dealerships, and brick-and-mortar retailers with store-goal PMax campaigns. If you have been running store-goal PMax at a flat setting, competitors who flip this toggle first can prioritize delivery for the nearest, most convertible foot traffic.

The move this week: open your store-goal PMax campaign, go to Budget and bidding optimization, enable Local customer optimization, and save. Flag a review for two weeks out to check store visit and local action metrics before and after. If you run product feeds through PMax, do not touch this setting; it will not apply and you should escalate a feature request instead.

OpenAI opens select health and finance categories to ChatGPT ads

OpenAI's ads policy page, last updated August 10, now permits specific health and finance categories to run ads in ChatGPT on a category-by-category approval basis. Sensitive conversations such as mental health discussions remain fully ad-free, and some healthcare advertiser types are still ineligible. A separate SE Ranking measurement found ChatGPT showed ads on roughly 28.69 percent of commercial healthcare prompts, more than ten times what was observed in Google's AI Mode.

This hits finance brands (lenders, brokers, insurance) and health brands (supplements, DTC wellness, consumer health devices) that were previously written off ChatGPT as a channel. It also hits agencies pitching those verticals who need to know what is now buyable.

The move this week: pull the current OpenAI Ads Policies page, map your product to the named categories on it, and submit an advertiser inquiry for any category where you appear eligible. Timebox this to forty-five minutes. Rules have changed four times since March, so log the version of the policy page you read against so your next review has a diff to check.

Snapchat rolls out multi-CTA disclaimer attachments for US pharma

Snapchat launched a new ad format for US pharmaceutical marketers that supports up to three disclaimer CTAs alongside a primary CTA, appearing below the main ad in the in-feed display. The format is live now across Snap Ads, Story Ads, and Commercials, with Sponsored Snaps support planned later this year. Snapchat frames it as a way for branded Rx campaigns to carry required safety information inside the ad unit itself.

This hits US pharma brand teams and their agencies running Snapchat, and any health advertiser using in-feed formats where safety copy currently lives in landing pages.

The move this week for pharma operators: pull the last three live Snapchat creatives, list every safety and disclosure link currently placed on the landing page, and rebuild one creative using the multi-CTA attachment format with those links attached directly. Send it to medical, legal, and regulatory review so approval time is scoped before the next flight, not during it.

Checked, and quiet

Nothing material moved this week on the SEO side worth an operator action: the AI visibility metric debate, ChatGPT search index coverage of small sites, and the ongoing WP Engine and Automattic dispute all rumbled on without a new decision or deadline. LinkedIn's AI optimization playbook and Reddit's new ad partners are noted, but neither requires a change to your setup this week. If any of these turn into a concrete move, they will show up in a future issue.
