Strategy Calls<\/a>):
\u2192 Have your campaign spend $10k in one hour because you accidentally enabled AI Max
\u2192 Copy-paste a faulty URL to Final URL without testing
\u2192 Set audiences to \u2018targeting\u2019 instead of \u2018observation\u2019 and then wonder where all the traffic went
\u2192 Launch new campaign on Friday afternoon, and then next Monday, find out that it spent the whole month\u2019s budget over the weekend
\u2192 Run PMax without guardrails and be surprised by it doubling spend via non-converting clicks from the Discovery network
\u2192 Forget to change Google\u2019s default location targeting setting and burn $20k on GDN traffic in India for a product only sold in the UK
\u2192 For US advertisers: target the country of Georgia rather than the state of Georgia
\u2192 Forget to hit the Publish button in GTM and then spend >\u20ac5000 on clicks only to see zero conversions
\u2192 Import GA4 conversions, forget to set the action as \u2018secondary conversion\u2019, and then have to explain why the spend tripled without a corresponding increase in revenue
\u2192 Let PMax auto-expand final URLs on a lead gen site and then see traffic to outdated blog posts explode.<\/p>\n\n\n\nHelp me prevent more mistakes by sharing yours? (Hit reply.)<\/p>\n\n\n\n
