Google Ads is preparing to change how its bidding systems handle campaigns that have spent months, sometimes years, converting well below the cost target their advertisers set. Starting August 17, 2026, and continuing over several weeks, budget-limited campaigns running Target CPA or Target ROAS bidding will begin delivering closer to the figures advertisers typed into their account settings. Google sent notification emails to affected advertisers today and published updated help documentation, according to a recorded conversation between Greg Finn of Cypress North and Barry Schwartz of Search Engine Roundtable, published as part of the "It's New" daily video series on July 2, 2026.

Finn described the arithmetic in round numbers: "if your campaigns are running and you have a target CP of 10 and it's actually bringing in five and it has been for, let's say, you know, 18 months or so, you might see a change for more predictable performance." He continued: "the change is that that 5 dollar acquisition cost you have is going to be moved up to 10."

What changes on August 17

The update applies to campaigns across Search, Shopping, Performance Max, Demand Gen, Travel, and Display that carry a "Limited by budget" status while running Target CPA or Target ROAS bidding. PPC Land's coverage of the original June 15 announcement cites Google's Help Center documentation, which states that "campaigns that are limited by budget that use a target-based bid strategy will more consistently perform toward your bid target, including when you make budget adjustments so you can grow your campaigns with more predictable performance." App campaigns, Video reach campaigns, and Video view campaigns are excluded. Hotel and Display campaigns already operate under the new logic and will not see anything shift on August 17 itself.

Under the prior system, a budget-limited campaign running Target CPA or Target ROAS could deliver conversions substantially below its stated cost target and simply retain the gap as apparent efficiency. Additional detail from PPC Land explains that "when a campaign has a 'Limited by budget' status and uses a Target CPA or Target ROAS bid strategy, the system may allow actual performance to exceed the stated target," and that "if the advertiser increases the budget, the bidding system may respond with performance fluctuations." Google frames the coming change as a fix for that inconsistency, while Finn offered a sharper reading in the recording, describing the update as arriving "under the guise of predictability and optimization" and predicting "we are going to see increased CPCs," since "you have to see increased CPCs if you're saying our acquisition cost is going to double." Schwartz, in the same recording, noted the volume of material Google published alongside the notification emails: Google "sent out an email this morning to advertisers who are impacted by this," along with "a brand new huge document discussing why this is so great," a video, and help-page revisions updated "over the past 12 hours or so" relative to the recording.

The Bid Target Adjustment Tool

A Bid Target Adjustment Tool becomes available inside Google Ads on July 6, 2026, four days from today, according to PPC Land's detailed account of the mechanics behind the change. It is triggered by account-level notifications sent to advertisers whose campaigns carried a "Limited by budget" status over the prior 12 months while running an affected strategy. Inside it, advertisers can keep the existing target and let delivery drift toward it, lower the target to match recent performance, or set an entirely new one. Switching toward Maximize Conversions or Maximize Conversion Value removes the target constraint altogether, trading predictability for volume-driven variability instead. The gap between July 6 and August 17 amounts to roughly six weeks, and nothing in the rollout adjusts targets automatically. The scale of exposure depends on how far actual delivery has drifted from the stated target.

A separate labeling change adds to the confusion

Layered on top of the August 17 shift is a cosmetic update that began rolling out earlier in June 2026. Google Ads started relabeling how Smart Bidding strategies appear inside the interface, with "Maximize conversions with a Target CPA" becoming simply "Target CPA," and "Maximize conversion value with a Target ROAS" becoming "Target ROAS." PPC Land's coverage of that relabeling notes the change affects naming only, though its arrival in the same month as the functional shift creates a real risk that advertisers will conflate the two updates.

Performance Max gains a new diagnostics view

A second, unrelated update covered in the same recording concerns Performance Max reporting rather than bidding mechanics. Google has begun testing a channel diagnostics feature inside the Channel Performance section of Performance Max campaigns, spotted by a user identified in the recording as Alexis, that consolidates diagnostics data across all channels into a single view.

This addition sits at the tail end of a transparency build-out that PPC Land has followed since April 2025, when Google originally announced channel-level reporting for Performance Max, describing diagnostic tools meant to help advertisers identify "problems such as missing store locations that might limit Maps performance or landing page relevance issues affecting Search placement." That beta reached advertiser accounts on May 30, 2025, and an alpha test spotted in May 2026 would go further still, letting advertisers exclude entire networks from delivery. Whether the diagnostics view spotted in this recording is a further step in that sequence or a distinct feature was not confirmed publicly as of the recording date.

Interface and email changes round out the Google Ads segment

Google has repositioned the "all campaigns" dropdown selector to the top left corner of the screen, spotted by a user identified in the recording as Hannah, who credited another user, Vivic Gupta, with the original find. Separately, Google Ads now includes an unsubscribe option in promotional emails sent under Google branding but originating, according to the recording, from third-party firms encouraging advertisers to book calls with "Google ad experts." The recording describes the sender identification directly: "these are really thirdparty emails from I think third party Google companies. It says Google customer solutions Monica on behalf of Google. But it's not really Google." An unsubscribe link is now present where none existed previously, following separate scrutiny of Google Ads email practices in May 2026, when Emmanuel Flossie, a Google Shopping Specialist and Google Ads Diamond Product Expert, alleged on LinkedIn that representatives were sending unsolicited commercial emails without a compliant opt-out mechanism, citing FTC guidance that "even if you hire another company to handle your email marketing, you can't contract away your legal responsibility to comply with the law."

Google Search changes how AMP pages route from search results

The recording also covered a change to how Google Search handles Accelerated Mobile Pages. Search results will now route users directly to the version of an AMP page hosted by the publisher, rather than through a Google-hosted cached copy, which was the original design of the AMP system, described as taking effect "starting today" relative to the recording date "to simplify and reduce maintenance efforts for publishers who are creating AMP content." The distinction carries weight because the original caching model had long frustrated publishers, a history the recording addresses directly: "we were really upset in the old days where Google's like this is going to make it faster. We're caching it for you. We're hosting it for you. But it reduced the amount of you could do with like analytics and tracking as well as monetization of those pages." The recording flags a rough edge from early testing, too: Glenn Gabe, an SEO consultant referenced in the discussion, reportedly attempted to load an AMP page under the new routing and received a "This page has failed to load" error.

Bing Webmaster Tools continuously backfills its data

The recording's final segment addressed Bing Webmaster Tools, where Glenn Gabe reportedly noticed on June 1, 2026 that AI performance reports across many advertiser profiles showed a marked increase in citation and impression data. When Gabe raised the pattern with Microsoft, a representative identified in the recording as Krishna characterized the increase as routine backfilling, a response the discussion frames as a pointed contrast with Google's own practices: "the no anomalies are basically a dig at Google because Google has a page around search console that talks about data anomalies whenever they have mistakes." Krishna's position was direct: "this is how it works. We're constantly backfilling data and just because you see a huge spike doesn't mean that there was any real change. It's just that we have more data to show you."

Continuous backfilling means a spike in reported citations or impressions cannot be read reliably as a signal of improved visibility without first ruling out a data-processing explanation. PPC Land's coverage of Bing's development timelinenotes that the AI Performance dashboard itself only entered public preview on February 10, 2026, and historical data retention within the tool moved from 6 months to 16 months in October 2024, then to 24 months in August 2025. Set against that backdrop of frequent structural change, a backfilling explanation for an unexplained spike is at least plausible, even where it leaves the underlying metric difficult to act on in the moment. The timing carries additional context: Fabrice Canel, the Microsoft principal product manager widely credited with shaping Bing's crawler infrastructure over nearly three decades at the company, retired on July 1, 2026, one day before this recording. Whether Canel's departure carries any bearing on how backfilling questions are handled going forward is not addressed in the discussion.

Why this matters for the marketing community

The August 17 bidding change is the most consequential item in this recording, and its weight comes from scope rather than novelty. Any budget-limited Search, Shopping, Performance Max, Demand Gen, Travel, or Display campaign running Target CPA or Target ROAS falls within its reach. Advertisers who have treated a sustained over-performing CPA as a stable baseline, rather than as a signal that their stated target no longer matches reality, have a narrow six-week window between July 6 and August 17 to adjust deliberately or accept the bidding system will do it for them. The Bing backfilling episode, though narrower, illustrates a recurring difficulty in search and ads reporting generally: platforms that continuously revise historical data create analytical friction for anyone trying to separate real performance shifts from processing artifacts.

Summary

Who: Google Ads and Google Search, covering all advertisers running budget-limited Target CPA or Target ROAS campaigns, alongside Microsoft's Bing Webmaster Tools team. The changes were discussed by Greg Finn of Cypress North and Barry Schwartz of Search Engine Roundtable in a recording published today.

What: A bidding target optimization change taking effect August 17, 2026, that moves budget-limited campaigns toward their stated Target CPA or Target ROAS figures rather than allowing continued over-performance; a new Performance Max channel diagnostics feature in testing; a repositioned all-campaigns dropdown; a new unsubscribe option for third-party promotional emails; a change routing AMP search results directly to publisher-hosted pages; and continued data backfilling in Bing Webmaster Tools that Microsoft characterizes as routine.

When: The bidding change was announced June 15, 2026, with the Bid Target Adjustment Tool arriving July 6, 2026, and the behavioral shift itself beginning August 17, 2026. The AMP routing change and impacted-advertiser notification emails went out today, July 2, 2026. The Bing data pattern was first noticed June 1, 2026.

Where: Across Google Ads, Google Search, and Bing Webmaster Tools, with the bidding change spanning Search, Shopping, Performance Max, Demand Gen, Travel, and Display campaign types globally.

Why: The bidding change addresses a structural inconsistency in how budget-limited target-based campaigns have performed relative to their stated targets, and it carries direct cost implications for advertisers who have relied on sustained over-performance. The Performance Max, AMP, and Bing updates reflect continuing, incremental adjustments to reporting transparency and data-handling practices across both platforms.
