Congrats to WooRank but this article doesn't touch on 'What we learned'. It was more, what we thought. In the end they seem to have made the right play by going freemium with a focus on full quality and limited quantity. (Give the users the full service only for a certain number of times per month)

I would be curious to know if they A/B tested different pricing strategies, did they speak directly to their bigger customers, how are they different from their competitors pricing strategy...

The price you charge for your services says a lot about your company's competitive ways. While obviously more complex than traditional pricing models, strategic pricing is the only pricing model that allows you to truly realize your profit potential.

very interesting
