These changes require immediate attention for accurate reporting and campaign optimization.",

"bodyMarkdown": "Starting in June 2026, Google Ads expanded product-level reporting for Performance Max campaigns to include data from all networks, not just a limited subset. This means advertisers using Google Merchant Center feeds will now see metrics like cost, conversions, impressions, and clicks aggregated across Search, Shopping, Display, YouTube, Discover, and more. The change, confirmed by Google in mid-July, can cause a one-time spike in reported data, forcing advertisers to explain sudden jumps to clients and adjust historical benchmarks.\n\nThis article breaks down the five most important Google Merchant Center and Google Ads updates that landed between June and July 2026, what they mean for your campaigns, and how to prepare.\n\n## Performance Max Product Reporting Expands to All Networks\n\nThe key change is that product-level reporting in Performance Max (PMax) campaigns now pulls from all networks. Previously, certain metrics were limited to a subset of placements, making it difficult to get a complete picture of product performance. As reported by Search Engine Roundtable, this shift means advertisers will see a comprehensive view of how individual products perform across the entire Google ecosystem.\n\nWhat this means for you: If you track product-level ROAS or cost metrics from Merchant Center feeds, expect a one-time increase in reported impressions, clicks, and conversions. This is not a real performance jump but a reflection of previously uncounted data. Advertisers should communicate this change to stakeholders and avoid making hasty budget decisions based on the spike. The update applies to all PMax campaigns using Merchant Center product data.\n\n## Google Clarifies Smart Bidding Updates for Budget-Constrained Campaigns\n\nA major cloud of uncertainty lifted in mid-July when Google explicitly stated that its upcoming Smart Bidding changes, effective August 17, 2026, are not a broad overhaul but a narrow adjustment for campaigns that are "limited by budget" and use target-based bid strategies (Target CPA or Target ROAS). The clarification came after heated industry speculation that the changes would affect all campaigns. Google's official statement, documented by Search Engine Roundtable, emphasizes that non-budget-limited campaigns will see no change.\n\nGoogle also introduced a new Bid Target Adjustment Tool, available from July 6, 2026, to help advertisers review and update campaigns that may be affected. According to Google Ads Help, the tool allows advertisers to simulate how their campaigns would perform under the new behavior and make proactive adjustments.\n\n| Change | Scope | Effective Date | Tool Provided | |--------|-------|----------------|---------------| | Smart Bidding for budget-limited campaigns | Only campaigns marked "limited by budget" with Target CPA/ROAS | August 17, 2026 | Bid Target Adjustment Tool (from July 6, 2026) | | Non-budget-limited campaigns | No change | N/A | N/A |\n\n## Google Launches Promotion Mode Beta for Short Promotional Windows\n\nGoogle introduced Promotion Mode in beta, a feature designed for advertisers running time-limited promotions. Available for Search and Performance Max campaigns using target ROAS (tROAS) bid strategies, Promotion Mode allows advertisers to schedule a promotional window of 3–14 days. During this period, the target ROAS is automatically relaxed, and the daily budget can be increased. After the window ends, the settings revert to the original values automatically, eliminating the need for manual adjustments.\n\nThe feature is particularly useful for Black Friday, seasonal sales, or flash deals. The beta is available to select advertisers; details were shared by smarter-ecommerce and discussed in the Search News Buzz Video Recap. To enable it, ensure your Merchant Center feeds have accurate promotional pricing and availability data.\n\n## Local Inventory Ads Will Turn On by Default for Shopping Campaigns\n\nIn a quieter but impactful move, Google Ads announced it will enable Local Inventory Ads by default for Shopping campaigns. This means that if you run Shopping campaigns with a Merchant Center feed that includes local store inventory, Google will automatically show those products in local ad formats. The change was highlighted by Search Engine Roundtable as a potential surprise for advertisers who had not opted in.\n\nWhat to do: Check your Shopping campaign settings to see if Local Inventory Ads are now active. If you do not want them enabled, you can manually disable them in the campaign settings. If you do want them, ensure your Merchant Center local product feed is accurate and up-to-date to avoid serving outdated inventory.\n\n## Practical Implications for Google Merchant Center Advertisers\n\nTaken together, these updates require a few immediate actions:\n\n- Benchmarking adjustments: The PMax reporting change means you should not compare post-June metrics to pre-June data without accounting for the expanded network coverage. Create a new baseline starting July 1, 2026.\n- Budget-limited campaign review: Use the Bid Target Adjustment Tool to check if any of your campaigns are flagged as "limited by budget" and whether the new bidding behavior will affect performance. For example, if you have a Target CPA campaign that is often budget-constrained, the change may either stabilize performance or require you to adjust your target.\n- Test Promotion Mode: If you have access to the beta, run a short promotion with a relaxed tROAS. Monitor the incremental revenue and ensure your product feed has correct promotion annotations.\n- Local Inventory Ads audit: Review your Merchant Center local product feed and Shopping campaign settings to confirm whether Local Inventory Ads serve as intended.\n\nThese updates reflect Google's ongoing effort to integrate Merchant Center data more deeply across ad formats and bidding strategies. While some changes may cause short-term confusion, they ultimately aim to provide more consistent and predictable performance for advertisers.\n\nStay tuned for further updates as Google continues to refine its shopping advertising ecosystem in the second half of 2026.", "faq": [ { "q": "What is the Performance Max product reporting change in 2026?", "a": "Starting June 2026, product-level reporting in Performance Max campaigns now includes data from all networks (Search, Shopping, Display, YouTube, Discover, etc.) instead of a limited subset.
