keeping the buyer in your mind
Firstly, I think it will be a little better if use the term audience instead of buyers but yeah it all depends on the nature of your site you can also use the term visitor instead.
Yes, I think one should keep their visitors in the head while making their website. The reason being if a visitor is satisfied when at the first impression then it could possibly help you generate leads which means you convert him/her to a buyer.
According to me, three factors play a key role in deciding the behavior of your visitors:
- UI of your website
- UX of your Website
- Content of your website
it's all about the profit, not the fame
Yes, even if you are talking about profits you need to focus on the optimization of your e-store.
Take an example of an offline market where you enter and you get to see only pricetags on the product and no real content for that product which could enlighten you to buy the product. Upon entering such store your first move would be to bounce back from the store. The same principle applies on your online stores.
