Delve's blog post breaks down the essentials for running a successful out-of-home (OOH) advertising campaign, based on their own large-scale experience in 2025. OOH advertising targets audiences outside their homes, contrasting with digital ads, and is effective for brands looking to make a significant impact. The ideal time to launch such a campaign is after achieving product-market fit and having a solid lead generation process in place. Delve emphasizes the importance of creating a sense of omnipresence; it’s not enough to just reach potential customers during their commute. Your brand should be visible in multiple contexts to create a lasting impression. Planning is critical. Delve suggests starting at least 3-6 months in advance for high-demand locations, like Times Square or major highways. For example, a campaign targeting San Francisco might require 40-50 advertising panels and a total budget of around $750,000. The planning timeline includes several steps: finalizing creative designs four weeks before launch, starting media planning two months prior, and selecting vendors three months ahead of the campaign start. Delve highlights that creative production can be time-consuming, often involving multiple feedback rounds before settling on the final design. Timing also plays a vital role. The article notes seasonal trends that affect advertising effectiveness, such as industry conferences and holiday periods. Delve identifies early September to early November as a prime window for B2B OOH spending, as companies look to close deals before the year-end. Understanding these nuances can help brands not only secure ad space but also maximize their return on investment.
