# LinkedIn Audience Efficiency ### **Drive Higher-Quality B2B Leads by Syncing Your ICP to LinkedIn** LinkedIn Ads offer strong targeting capabilities, but native filters can sometimes include roles or titles that don’t closely align with your ideal buyers—especially in B2B campaigns. Primer enables you to define your Ideal Customer Profile (ICP) more precisely outside of LinkedIn and then sync that refined audience directly into your ad campaigns. This approach helps improve targeting accuracy and lead quality. For more details and performance benchmarks, refer to [Primer’s LinkedIn Efficiency guide.](https://www.sayprimer.com/use-cases/primer-linkedin) {% embed url="" %} ### How to Build and Sync ICP Audiences for LinkedIn: * **Create your ICP audience in Primer:**\ Define your ideal companies, departments, seniorities, and titles. Preview your audience to ensure quality before syncing. * **Sync the audience to LinkedIn:**\ Push your custom audience into LinkedIn as a matched list. Note: full population can take up to 72 hours. * **Run a test campaign:**\ Compare LinkedIn’s native targeting vs. your synced ICP audience by running A/B tests. * **Track performance:**\ Measure form completions, qualified leads, CPL, CPM, and CPA over 1-2 weeks to evaluate impact. ### Why It Works: * LinkedIn’s native filters are good—but can be too broad * Primer’s synced audiences offer tighter control and precision * Avoid “close but wrong” titles for better lead quality and ROI --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
