Totally agree with fonzi. A heatmap can be awesome. Tools like Crazy Egg or Clicktale a great for this. It’s huge to keep track of for testing and seeing what your users like, as well.
Also, I would say social media icons so your visitors can follow you and get updates for other channels (Like Facebook, Twitter & LinkedIn)
Lastly, a dedicated area for visitors to know of the top performing brands and limited time promos, so they can just head to a dedicated spot.
