If I understand your question correctly, you're asking if we optimize for traffic -> any plan vs. traffic -> total revenue? Right now it's pretty unsophisticated and we're not really measuring/optimizing on getting people to select a higher plan vs. a lower plan. I'm sure as we nail more of the basics down this is something we'll focus on in the future though.

Generating top of the funnel is actually really hard and something we struggle with a lot. Writing blog posts and posting them on Hacker News (like this one here) result in huge bumps of traffic but it's not really scalable. We added a small "powered by statuspage.io" at the bottom of every status page and are going to do more SEO-minded blog posts.

For early stage startups where there isn't already much of a market (there aren't a lot of companies doing status pages as a service), a lot of traffic and eventual customers come in via word-of-mouth. We have some plans to really give our customers an amazing experience with our product and company as a whole with the hope that it will get people talking about us.
