The lookalike audience feature allows you to target people or companies with similar characteristics to your matched audience segment. Using your data as a source, LinkedIn member profile data and company attributes are used to determine similarity to expand your audiences, which means your lookalike audience size can be up to 15 times larger than your original audience size, and the original Matched Audience is not included.
The LinkedIn Audience Network is a feature that allows you to extend the reach of your single image, carousel and video ads by delivering beyond the LinkedIn feed to members on third-party apps and sites.
What is the ideal audience size?
The minimum audience size required to run an advertising campaign is 300 members; however, to have the optimal scale for your campaign, aim for an audience size of 50,000 or more for single image and text ads and over 15,000 for message ads.
Can you add or exclude audiences on LinkedIn?
LinkedIn’s targeting allows you to customize your audience using LinkedIn’s demographic/firmographic data and your data such as matched audiences. The ‘AND-OR’ feature helps you further refine your targeting criteria by using either ‘Narrow’ or ‘Exclude’ audiences. For example, you can target the job title of Software Engineer OR the Software Engineer skill AND have 5+ years of experience AND exclude the job title of Design Engineer.
