Every Google search triggers an auction, and the auction is not won by the biggest wallet — it is won by relevance. Google discounts clicks for advertisers whose ads, keywords and landing pages genuinely answer the search. That means a disciplined account pays structurally less for the same customer than a sloppy one, forever.
But accounts decay. Search terms drift away from intent, broad match wanders, budgets bleed into queries that will never buy. In most accounts we open, a fifth to a third of spend is doing quietly nothing — not because anyone is negligent, but because no human can re-read thousands of search terms every week. The waste hides in the volume.
The remedy is method: airtight structure, negative keywords maintained like a hedge, bids tied to what a sale is actually worth, and conversion tracking honest enough to steer by — including the sales that close offline, days later.
