The fastest way to waste a paid advertising budget is to treat every platform the same way. Google Ads, Meta, and LinkedIn each reward a different kind of campaign structure and creative approach.
Search campaigns work because they intercept someone already looking for a solution. The biggest wasted spend usually comes from broad match keywords pulling in searches with no real commercial intent, not from the bidding strategy itself.
Modern Meta and TikTok algorithms have largely automated audience targeting. The performance differentiator has shifted almost entirely to creative quality and volume of variations tested, not manual audience building.
LinkedIn's cost per click is consistently higher than other platforms, which only makes sense for offers with a high enough deal value or lifetime value to justify it, typically B2B and higher-ticket services.
For most small businesses, Google Search Ads offer the most immediate, measurable return because they capture existing demand rather than trying to create it.
Testing 5 to 10 distinct creative concepts per campaign, not just color or headline variations, is a common baseline for finding what resonates before scaling spend.
Usually not. LinkedIn's higher cost per click is difficult to justify unless the average deal value or customer lifetime value is high enough to absorb it.
