LinkedIn recommends starting with a broad targeting scope to allow the algorithm to learn and optimize, then refining based on performance and audience insights. Tailoring content for segmented audiences ensures relevance and engagement. Adjusting the audience based on ideal customer profiles (buyer personas) improves targeting accuracy. Avoiding inferred characteristics and focusing on explicit data prevents misinterpretations and ensures more precise targeting. Segmenting campaigns by region allows for localized messaging and budget allocation, optimizing for geographical nuances.
