Have you watched Dan Ariely's TED talk on irrational decision making? Your revised pricing tiers reminded me of the discussion about tom, jerry, and "slightly ugly" jerry around the 15:00 mark. If you haven't seen it, it's interesting that you've stumbled on the effect independently.

You might find that further tweaks push more people to the agency tier by creating a "slightly ugly" agency instead of a "slightly ugly" studio -- freelancer.

Love that talk, thanks. I do have some ideas for tests I want to run in the future when I get back into optimization mode.

I've wanted to a/b test my plan name but don't know of any good alternatives. I have a free WordPress plugin and have a paid-for version which adds more features so it's called generically 'Premium version'.

The people who buy it come from different backgrounds and I don't want to segment the product.

It's a recipe plugin and the premium version adds a nutrition tab to satisfy the nutritionists and category listing pages for people who want to organise their recipes more than what the free version allows.

Any thoughts on a name?

Don't take it the wrong way, but you're trying to squeeze your users into the rigid frame of your preconceived notions about who they are. Changing people is a very difficult job. I understand you put a lot of effort into your product and feel entitled to steer it as you see fit, but it's far more productive to do what the topic post suggests - ask the users who they are and what they care about. In other words, reconsider your decision not to segment.

mmh how about "Hobby" and "Passion"? I got nothing. To be honest I'm not sure whether those features are a good way to diversify, but then again I probably don't know enough about your product.
