Issue with Google Ads PMax Campaigns Attracting Bot Traffic and Overspending
Issue with Google Ads PMax Campaigns Attracting Bot Traffic and Overspending I’m currently facing a serious issue with my Performance Max (PMax) feed-only campaigns on Google Ads. Despite working with a highly experienced agency—who has a proven track record of over $100 million in revenue and 5+ ROAS with other clients—our campaigns are suffering from what appears to be bot-dominated traffic. Symptoms: - 99% of clicks appear to be from bots: Unrealistic click behavior with no engagement or conversions. - Extremely low CPCs (e.g., €0.01–€0.03) despite running high-ticket products (luxury segment in Germany). - Unrealistic impression spikes: Massive impression and click surges often occur within the first few hours after midnight. - Budget drain: Campaigns frequently overspend their daily budget limit (DSL) within a very short time, with no meaningful traffic or results to show. Background: - I sell high-ticket products in Germany and rely on shopping ads for qualified traffic. - This issue started after my Google Merchant Center (GMC) account was suspended, due to a false flag claiming there were "no products" on the site. - We contacted Google support, who reviewed the case and confirmed there were no actual violations. Our GMC and products were reinstated. - To be safe, we switched to a new Google Ads account, which initially performed well for about five days. After that, the same pattern re-emerged—huge traffic spikes, bot-like behavior, overspending, and no real conversions. What We’ve Tried: - Switching ad accounts - Working with a top-tier agency - Verifying all merchant/product/account setup issues were resolved - Contacting Google support (no clear answers so far) Request for Help: We’re at a loss here. Even with experienced help, everything seems to be technically correct, yet the campaign performance is entirely unrealistic. It behaves like a bot farm is targeting the feed-based campaigns. Is this related to: - A shadowban or flag on the domain after the temporary GMC suspension? - A structural issue with the PMax campaign or targeting logic? - An underlying security or tracking problem? - A Google-side glitch or system abuse?
