PPC Land’s October 31 edition opens with a title that reads like a party game: “Game: Search and social still argue about who found the customer.” The newsletter, written by Luís Rijo since 2016, has published over 10,000 articles and likes to turn familiar performance marketing tensions into something worth debating.
The argument is old, but the budget stakes are not. Search and social teams often compete for the same conversion credit, and the channel that gets the credit usually gets the bigger slice of next quarter’s plan.
Why the fight never ends
Last-click attribution loves search. Someone types a query, clicks a branded ad, buys. Search looks like the closer.
Social’s role is messier. A campaign may plant the idea days earlier, but the customer never clicks. When they finally search and convert, search claims the sale. Social gets a view-through or nothing.
That gap explains the argument. The channel nearest the transaction gets the trophy, while the channel that created demand has to prove itself with weaker measurement.
How the platforms keep it alive
Google Ads and Meta each report the same order through their own dashboards. If a user watches a social ad, then searches a brand name, both platforms can look like the winner. Without deduplication, internal reports overstate performance and feed the blame game.
Platform self-attribution is not a conspiracy; it is a design choice. Each platform measures what it can see. The marketer’s job is to stitch those views together and add experiments on top.
What to do instead of picking a winner
- Value the full funnel: give social partial credit for early influence and search credit for closing high-intent demand.
- Run incrementality tests: pause or geo-hold a channel and measure total revenue lift, not just platform-reported conversions.
- Adopt media mix modelling: use MMM for longer-term brand and demand spend, where click data undercounts social.
- Set one north-star metric: align both teams on pipeline or revenue contribution, not clicks or ROAS alone.
Stop asking who found the customer
Framing attribution as “who found the customer” turns growth into a zero-sum game. That usually rewards whichever channel is easiest to measure, not which one grows the business.
Growth teams that move from “who sold it” to “what moved the number” tend to waste less budget. The better question is: what role did each channel play, and what happens when you remove it? That answer leads to budget decisions based on contribution, not credit.
