Top Learnings from Someone Who Has Done 300+ Websites for Startups

Without any qualitative data to back this up, these are merely the feelings and intuitions of some random web developer. While these feelings and intuitions may be largely accurate, without any actual evidence to support the hypothesis "These tactics lead to higher conversion rates" there's no reason anyone should take them remotely seriously. Just reads like a list of things everyone else is doing, and as we should all well know by now, conventional wisdom is often conventional, but seldom as wise we might think.

Now show me hard data from a properly designed and controlled experiment where you assess the objective conversion performance of websites before and after implementing these specific tactics and I'd take you a lot more seriously. Instead of just saying "Do these things" you should be saying "I did these things, and here's the data that show's how they affected conversion rates."

Reads like a thesaurus entry for the word manipulation.

You should also consider making a really useful product that people want.

If it's that dependent on the marketing being perfect then maybe your product isn't very innovative.

Which is fine, there are many people who are incapable of innovating and have to rely on marketing the same old products. But those who can innovate and create better products should focus their energy on that. In my opinion.
