The only channel where the buyer tells you what they want first.
That advantage disappears the moment the account optimizes toward the wrong conversion.
Is paid search worth it for B2B? Almost always, if demand exists for your category. Search captures intent rather than creating it, which makes it the highest-converting channel available and caps its ceiling at existing demand. The failure mode isn't keyword selection. It's feeding the bid algorithm form fills instead of closed revenue.
Where paid search works, and where it doesn't.
Where it works
- Established categories where people search by problem or by competitor
- Long sales cycles, because search catches the buyer at the moment of active evaluation
- Anywhere you can push CRM outcomes back into the platform
Where it doesn't
- Genuinely new categories nobody knows to search for
- Under ~$15K a month with no existing brand demand
- Products where the buyer never searches, because the category is entirely sales-led
Three expensive mistakes.
Optimizing to form fills.
Google finds people likely to submit forms, which in B2B skews to researchers, consultants, and competitors. Push closed-won and pipeline stages back via offline conversion imports and enhanced conversions for leads, and the bid model learns what a buyer looks like.
Twelve campaigns, none of them learning.
Smart bidding needs roughly 30 conversions per 30 days per campaign. Budget split across a dozen tightly themed campaigns produces a dozen campaigns guessing. Consolidation feels like losing control and is usually the fix.
Letting Performance Max eat brand.
PMax serves on brand queries and reports them as prospecting, which flatters the campaign and hides what prospecting costs. Brand exclusion lists on day one. At Pebl, separating brand from non-brand took brand click cost from $16.82 to $4.59 and cut CPC 49% in a quarter.
What actually gets built.
Offline Conversion Imports
Closed-won and pipeline stages pushed back on a schedule, with enhanced conversions for leads covering the GCLID gaps iOS creates.
Consolidated Structure
Fewer campaigns carrying more conversions each, so bid strategies have enough data to learn from.
Brand Discipline
PMax exclusions, separate brand budget, and reporting that never blends the two into a flattering average.
The Platforms Nobody Runs
Microsoft Ads for the enterprise and desktop skew at materially lower CPCs, Reddit for technical categories, and ChatGPT ad inventory as it opens up.
The honest part.
Under about $15K a month with no existing category demand, search spends your budget on the periphery and teaches you little. Start with LinkedIn or founder-led content.
Competitor campaigns deserve their own warning: cheap, satisfying, easy to defend in a meeting, and in a real share of accounts they produce enough clicks to look busy and not enough closed revenue to justify the line.
What buyers ask first.
