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.

Do a google search for karma based marketing - Colin from Customer.io does an amazing job getting people talking about his company.

We aren't using Google Analytics goal conversion tracking.

Mixpanel was extremely useful just to see where the huge holes in our funnel were. For example, only 30% of the people that see our signup page end up signing up. Now that we know a lot of people are following through with signup, we're focusing attention this week on improving that number.

We just started using Optimizely and so far it's been great but I haven't used it enough to really comment. Optimizely seems to be really great for micro-optimizations and we've been focusing on bigger complete page redesigns thus far.
