Broad Targeting That Inflates Audience and Wastes Budget
LinkedIn surfaces an "audience too small" warning below 50,000 people, which leads many advertisers to widen their targeting until the warning disappears. The result is an audience that includes job titles, seniority levels, and company sizes that have no purchase authority for your product. CPCs stay high, conversion rates collapse, and the campaign is written off as a platform problem rather than a targeting problem.
