For this example, I'll be visiting OldNavy's website (online retailer) and then GapInc's (corporate).
First, OldNavy is more colorful and appealing to the eye, it has the sale percentages in large font and the name of the sales. Secondly, the corporate website barely talks about the products and is more on the business side of things with their mission and information about the company. Lastly, the retailer categorizes by gender and type of clothing while the corporate categorizes by Jobs, News, etc.
I hope this helped you have a good one!
