Digital Marketing Platform Updates: 31 August 2026
A busy couple of weeks across the platforms. Google quietly changed how your bidding works, Meta started rewriting your ad images without asking, and a spam update rolled through Search. Here is what matters and what to do about it.
Google Ads
Bidding Overhaul: Budget-Limited Campaigns Now Honour Your Targets
What changed: From 17 August, Google changed how Smart Bidding handles campaigns that are limited by budget. Previously, if you set a Target CPA or Target ROAS and your budget was too small to fully serve at that target, Google would relax your target to spend the budget. Now, it optimises toward the target you actually set, even when you increase your budget.This applies to Search, Shopping, Performance Max, and Demand Gen campaigns.
Why it matters: This is a significant shift. If you have been running budget-limited campaigns with a target CPA (which is most SME advertisers), your campaigns may now be spending less aggressively to stay closer to your target. That could mean fewer conversions but at a more predictable cost, or it could mean your budget is suddenly underspending. Either way, your numbers have likely shifted since 17 August. What to do: Check your campaigns from 17 August onwards. Compare spend, conversions, and CPA against the week before. If you are seeing underspend, you may need to loosen your target slightly to get volume back. If performance has improved, leave it alone and enjoy the efficiency.Promotion Mode (Beta)
What changed: Google launched a new beta called Promotion Mode for Search and Performance Max campaigns. It lets you schedule a temporary window where your ROAS target loosens and your daily budget increases, then automatically reverts when the promotion ends. Why it matters: If you run flash sales, seasonal offers, or event-based promotions, this is genuinely useful. Previously, you had to manually adjust targets before a sale and remember to change them back. Promotion Mode automates that. What to do: If you regularly run short-term offers, ask your account manager about the beta or check for it under your campaign's bidding settings. Particularly handy heading into the Christmas and Black Friday window.AI Max Gets Proper Testing Tools
What changed: Google's AI Max for Search campaigns now supports A/B experiments with brand and location controls. You can test AI Max with your brand terms protected and your geographic targeting locked, then measure the impact before committing. Multi-campaign budget and ROI testing across Search campaigns is coming in September. Why it matters: AI Max has been polarising. Some advertisers see great results; others see wasted spend on irrelevant queries. The addition of brand and location controls in experiments means you can now test it properly without the risk of it cannibalising your branded traffic or targeting outside your service area. What to do: If you have been hesitant about AI Max, now is a good time to run a controlled experiment. Set up a test with brand exclusions and your correct service locations, run it for two to four weeks, and let the data decide.Local Services Ads Moving Into Google Ads
What changed: Google has begun migrating Local Services Ads (LSA) into Google Ads as Performance Max pay-per-lead campaigns. The first phase covers select U.S. home service categories starting in August, with broader rollout through late 2026 and non-U.S. markets in 2027. Why it matters for Australian businesses: This does not affect you yet. But it signals the direction: LSA will eventually be managed inside Google Ads for all markets. If you currently run LSA, your workflow will change. The good news is you still only pay per lead, not per click, and ads will still appear on Search and Maps. What to do: Nothing right now. But if you run LSA, start familiarising yourself with Performance Max so the transition is not a shock when it reaches Australia.Google Search
August 2026 Spam Update: Done
What changed: Google rolled out its August 2026 spam update on 18 August, and it finished on 21 August, taking just under three days. It was the third spam update of the year. No new spam policies were introduced. Why it matters: If your organic traffic or rankings shifted between 18 and 21 August, the spam update may be the cause. Google did not announce any new rules, so existing spam policies (cloaking, doorway pages, link spam, thin content) are still the benchmark. Why it also might not be the spam update: There was notable ranking volatility in early-to-mid August (around 1-3 August and again 12-13 August) that Google never confirmed as an algorithm update. Multiple trackers flagged elevated movement, but the cause remains unclear. If your rankings shifted before the 18th, something else is going on. What to do: Compare your Search Console data before and after 18 August. If you lost rankings, review your site against Google's spam policies. If the drops predate the 18th, it is likely unrelated to the spam update; look at your content quality and technical SEO instead.Meta Ads
Meta Is Now Rewriting Text in Your Ad Images
What changed: Advantage+ Creative can now take an image you uploaded and generate new versions with the headline text rewritten. The font style, colours, layout, and background stay the same. Only the words change. This is on by default.For example, an ad with the headline "Premium LED Screens for Events" might get a variant that says "Your Event Deserves a Better Screen", using your exact font, colours, and layout.
Why it matters: This is a big deal. Meta is no longer just tweaking ad copy in the text fields. It is modifying your actual creative assets. For brands with strict messaging guidelines, compliance requirements, or carefully worded offers, this could produce variants that misrepresent your service or undermine your positioning. What to do: Check your ad previews in Ads Manager. Look at the "Creative" section of your ad setup for the Advantage+ Creative options. If you see a "Text" option under the creative enhancements, review it. If your brand needs tight control over messaging, turn this off at the ad level. If you are comfortable letting Meta test different angles, leave it on and monitor your creative reporting to see which variants perform.Messenger Stories and Explore Feed Placements Removed
What changed: As of 27 August, Messenger Stories is permanently removed as an ad placement. Instagram Explore Feed now returns an error when specified in API calls. These changes are part of Meta's Marketing API v26.0. Why it matters: If you are running Advantage+ placements (which most SME advertisers should be), this likely has minimal impact because Meta automatically reallocates budget to remaining placements. But if you had campaigns manually targeting Messenger Stories, those need updating. What to do: Check any campaigns with manual placements. If you see Messenger Stories listed, remove it to avoid delivery issues. If you are using Advantage+ placements, no action needed.Delivery Estimate Tools Removed from API
What changed: Meta removed thedaily_outcomes_curve, budget_guardrail, and estimate_dau fields from the Delivery Estimate endpoint with no replacement.
Why it matters: This mostly affects agencies and third-party tools that used these fields for budget planning and forecasting. If you use a media planning tool that suddenly stopped showing audience size or budget recommendations, this is why.
What to do: If your planning workflow relied on these estimates, check with your tool provider for updates. For most SME advertisers managing campaigns directly in Ads Manager, this will not affect your day-to-day.
Worth Watching: ChatGPT Ads
OpenAI continues to build out its advertising platform. In August, ChatGPT Ads gained conversion-optimised CPC bidding (oCPC) in beta, began testing multi-product carousels, and expanded to Brazil and Mexico. Automatic Advanced Matching became the default for all new web pixels on 17 August.
This is still early days. Most Australian SMEs will not be advertising on ChatGPT yet. But the pace of development is notable: OpenAI is building a full-featured ad platform remarkably quickly. We will cover it more thoroughly once it becomes relevant for the Australian market.
The Takeaway
The Google Ads bidding change from 17 August is the one to check on immediately. If you are running budget-limited campaigns with Target CPA or Target ROAS (and most SME advertisers are), your performance data has likely shifted. Review the last two weeks and adjust your targets if needed. And if you are running Meta ads, check whether Advantage+ Creative is rewriting your ad images without your knowledge.
