"Personalize the landing page for every traffic source." [DEPENDS]
A company built 14 source-specific landing variants - separate copy per ad campaign. Six months in, only 3 variants beat the generic control; the other 11 cost more in maintenance than they returned.
Why it spread: "message match" is gospel, and personalization sounds sophisticated.
The boring truth: message-match pays only where intent genuinely differs. Splitting "download the guide" traffic into 14 near-identical pages just multiplied your testing surface and starved each variant of the volume needed to reach significance. You diluted the data and bought yourself a maintenance bill.
The nuance the personalization hype skipped: the 3 winners mapped to distinct intents - branded search vs. cold display vs. retargeting. Personalize across real intent gaps, not across ad IDs. More variants isn't more relevance; it's usually just more pages to maintain and less data per page.
