WHY TOO MANY MICRO-CONVERSIONS HURT PPC PERFORMANCE

Summary from the TLDR Marketing newsletter

Tracking too many micro-conversions as primary signals in PPC campaigns can degrade performance by shifting algorithmic bidding toward high-frequency, low-value actions. In some accounts, micro-conversions outnumber real conversions by a ratio of 500 to 1, causing the system to chase cheap signals while actual revenue stagnates. Value-based bidding helps, but cannot fully override signal imbalance when low-intent actions dominate the optimization math. The recommended approach is to limit primary conversions to one or two high-intent actions, use a 25% safety discount when assigning micro-conversion values, and transition to revenue-based optimization once campaigns reach 30 to 60 real conversions per month.
