We debated this one quite a bit, and ultimately went with a free tier instead of free trial because: (a) it gives us public free content that can be used for SEO, and (b) reduces the barrier for trial and sign up.
Finally, the free tier is data from a year ago instead of the most recent publicly available data (2 months ago), so while retailers can get some benefit, the paid tier is much more fresh and actionable.
