Four Stages of Search Experience (Mobile eCommerce)

Hi designers, I just started writing little UX articles about current mobile UI trends that I observed and am obsessed with. Design trend is always changing. The question "What is the best design solution" never has a textbook answer. Therefore I'm doing this to keep myself updated, observing, and thinking deep.

The 1st topic that I'm writing about is Four Stages of Search Experience (Mobile eCommerce)

Please take a a few minutes to read it and I'm looking forward to any feedback!
