Software-as-a-Service (SaaS) startups rely on digital channels to distribute their services and to acquire, engage, and retain customers. This makes web metrics, such as monthly visitors, bounce rate, page views per visit, and session duration, a critical barometer of commercial traction. However, little academic work has quantified these metrics at scale across global SaaS ecosystems, leaving a gap in benchmarking and understanding their variation. This study presents a descriptive snapshot of social media adoption and baseline web performance for 21,818 SaaS startups founded between 2015 and 2024. Results underscore LinkedIn’s near-ubiquity. Roughly 89% of SaaS startups maintain an active page, whereas Facebook and Twitter/X each reach just over 50% adoption. Website engagement remains modest across the sample. The median SaaS startup records about 1500 monthly visits, a 138-second session, 1.8 page views per visit, and a bounce rate of 65%. A regional comparison across the 10 largest ecosystems globally, based on the number of SaaS startups funded, reveals broadly similar figures except in Brazil, where SaaS ventures report roughly twice the traffic and session duration, and more than triple the page views of global peers. This snapshot provides researchers with a global benchmark of SaaS social media adoption and core web metrics, while offering practitioners reference points to assess and improve their own traffic and engagement. The persistently high bounce rates observed, point to the need for deeper investigation into how a startup’s stage, funding level, and underlying business model, shape conversion outcomes.
