- Move the search bar to one of the sides. Right now it's at the top, in a prominent position that you could be using to promote the guitar that you're promoting.
- Your call to action needs to be a lot clearer. Make it a button, split test different texts to see which results in the best CTR.
- The layout really confused me. Is the big guitar at the top the one you're trying to sell? If so, what is with the variations of it below? Your focus needs to be on the main guitar you want to sell. One or two related products is fine, but not the number you have there.
- Too much text. Add a star rating out of 5, bigger bullet points, anything to make it look less like an essay.
- On a similar note, instead of using default text, why not write a more personal review about the guitar? Give it a more personal touch, so people feel more reassured that it's a real musician recommending it and not just some random text a guy grabbed off another website.
- Put the price above the fold, preferably near your button. The merchant's page is a great example of how you should lay out your site, or, as has been suggested, Amazon or Ebay are also good. They're the big boys, who have probably spent hundreds of thousands of dollars trying to perfect their layout over the years. Use their research to your advantage when making a layout for an e-commerce shop.
