When you get right down to it, there aren’t many reasons not to sell on Amazon. The largest online retailer in the world didn’t earn that title 
without attracting millions of unique visitors every single day. So even if you have your own eCommerce website, keeping some listings active on Amazon can’t hurt. However, if you know what you’re doing and implement a sound strategy, Amazon could become a source of very real revenue. Anyone can get started on the retail giant; here are some tips to help you succeed.
First of all, don’t get lazy when you place products. Too many people let Amazon do the heavy lifting and, at best, depend on positive customer feedback to augment their results. This doesn’t help you stand out from the competition, though, and there will be plenty of that on Amazon.
Instead, provide four or five photos with each of your listings and ensure they’re high quality. Will this take a couple extra minutes per posting? Yes. Is it worth it? Absolutely. Be sure to review Amazon’s guidelines, however, as they have requirements in terms of image size, white space and more.
Nowadays, Amazon will even allow you to provide videos. If you’re selling books or DVDs, this may not be necessary. However, more technical items could benefit from having a video to educate the buyer.
Now, just like the content you put on your website to advertise your products, you want to use compelling copy to sell your product on Amazon too. You’ll also need to check the rules here because character limit differs by product.
Use a title that is both accurate and keyword rich. No matter what the product, you won’t have a ton of characters to work with though. However, now is not the time to offer any promotions you may be running or product information.
What a lot of savvy Amazon sellers do is check their paid search ads to see which words convert the best. Obviously, you should be doing this anyway to update your website’s keywords. However, leveraging this method for an Amazon post is just as good a reason.
When it comes to the product description, swing for the fences. Really tell a story, not just about the item, but your company too.
Many people don’t succeed with selling on Amazon because they expect it to be easy. It’s Amazon, after all! The truth, however, is that you need to implement a sound strategy that includes the above tips.
