The 5 Numbers Every New LinkedIn Advertiser Needs to Know Before They Launch

LinkedIn is the most expensive ad platform in B2B and the most precise. Whether that trade is worth it for you comes down to five numbers you should know before launch.

• ›››Your average contract value — under ~$10k LTV, LinkedIn math gets hard
• ›››Your realistic monthly budget — $5k–$10k is the working floor
• ›››Your addressable audience size — 30k–300k members is the sweet spot
• ›››Your sales cycle length — it sets the timeline for judging results
• ›››Your current close rate — ads amplify a working motion, they don’t create one

Run the math before the platform does

Every one of these numbers feeds a simple model: cost per qualified conversation versus what a closed deal is worth. If the model works at benchmark CPLs, LinkedIn will likely beat it. If it only works at fantasy CPLs, fix the offer first.
