How Long Do B2B LinkedIn Ad Campaigns Run? 40,816 Observed Campaigns, By Industry and Funding Stage

A median alone hides how spread out campaign lengths actually are. 23.8% of dated campaigns run 7 days or less, and 11.8% run past 90 days.

The spread is real: among the 17 industries with enough data to report, the shortest median is Energy & CleanTech at 12 days and the longest is Logistics & Supply Chain at 42 days, against the 19-day site-wide median above. Industries below 5 advertisers or 300 dated campaigns are excluded from this table rather than shown on a thin sample.

Funding stage moves duration far less than industry does. Seed through Series C cluster within a narrow band, and the visible step-up only shows up at Series D and Series E. Series D and Series E are shown at the gate's minimum sample size (5 advertisers) and should be read directionally, not as precise estimates. "Public / IPO" ships at its own measured numbers below; it is not merged with the separate, thinner "IPO" label some companies carry, which does not clear this table's gate on its own.

Source and filter. Published AdPeekly ads, deduplicated to one row per creative template, restricted to the 40,816 of those where LinkedIn also reported a campaign start date. For the rest, the only measurable span is how long AdPeekly has been watching, which describes our scraping schedule rather than the advertiser's decision, so those are excluded rather than mixed in. Industries and funding stages below 5 advertisers or 300 dated campaigns are excluded from their tables, a page-specific bar stricter than AdPeekly's browsable gallery pages, because this page states single numbers as citable facts. Full detail on the methodology page.

Every figure on this page is reproducible from AdPeekly's own dataset and refreshed periodically. Citing a specific number: link to this page directly rather than a screenshot, since the underlying figures update as the dataset grows.
