B2B paid search is becoming less efficient due to two converging factors. First, AI-driven zero-click searches are reducing overall click volume. Second, a surge of venture capital into tech is inflating costs per click (CPCs), making the channel much harder and more expensive to master.
Agencies often use low impression share as a seductive argument for increasing ad spend. The critical pushback is to ask for the breakdown between "impression share loss to rank" and "loss to budget." High loss to rank points to fixable quality issues, not a need for more money.
To avoid growth stagnation, every marketing budget should have a dedicated percentage (10-20%) for testing new channels and formats like AI Max or YouTube ads. Running the same playbook for years without exploring new avenues for asymmetrical upside is a recipe for diminishing returns.
B2B paid search often fails because agencies focus on platform metrics (e.g., demos booked) instead of business outcomes. True success requires deep CRM integration to optimize for qualified pipeline and revenue, a step most agencies are not equipped or incentivized to take.
The common agency model of charging a percentage of ad spend creates a conflict of interest. It incentivizes agencies to push for higher budgets rather than focusing on efficiency and driving core business outcomes like pipeline and revenue. A flat fee aligns incentives better.
Many B2B paid search campaigns fail not from low budget, but from a low Quality Score causing high "impression share lost to rank." This fundamental mismatch between keywords, ads, and landing pages throttles ad delivery, a problem that cannot be solved by simply increasing spend.
With soaring non-branded CPCs and the rise of zero-click search, running branded campaigns is increasingly vital. As users get information from AI summaries or social media and then search a brand directly, these campaigns become a highly efficient, low-cost way to capture high-intent traffic.
The 'fractional head of growth' model, where a senior leader brings their own execution team, directly counters the common agency problem of clients being sold by a founder but serviced by junior staff. This structure ensures consistent, senior-level oversight on all accounts.
In today's market, paid search is ineffective for demand creation; it only works for demand capture. Viable companies must already have significant demand for their brand, category, or problem, and a high average contract value (ACV) to absorb the increasingly high customer acquisition costs.
Striving for 100% impression share is a flawed goal. For any given keyword, a large percentage of searches are irrelevant to your specific solution (e.g., "CRM for plumbers"). The focus should be on dominating the slice of high-intent searches that matter, not on appearing for every variation.
Performance Max (PMAX) is often a top pipeline-producing campaign in Google Ads, but it comes at a cost: a high volume of low-quality leads. The campaign's "black box" nature offers little granular control to eliminate waste, leading many B2B teams to turn it off despite its apparent successes.
Rather than killing an underperforming paid search channel, cut its budget significantly and reclassify it as a "tertiary pipeline source." This frees up capital to invest in demand creation, which can improve the performance of your now smaller, more efficient paid search efforts.
