This is a very basic tutorial, not only about how to photograph products, but why

It's largely about the lighting, and getting the lighting anywhere near right when shooting with natural light depends on weather and luck, it's so much easier, and so much more controllable, indoors.
But, there's far more to it than just lighting, camera position and other obvious ingredients. If you're trying to sell a highly competitive product, where most people buy mainly or completely on price, the photos need to be so much better than if you're selling something that people don't want to buy but actually need, here's an example of a product that sadly I have to buy, so the photos are really of little or no importance.

My approach - but I'm old-fashioned - is to try to get the images perfect in camera, but the reality is that even I accept that a fair bit of retouching is always essential, and that's a separate skill.
The camera, BTW, is neither here nor there.
My advice? Research your competitors thoroughly, concentrate on those who have the highest sales, see what they do in terms of both photos and text, and use that as a model. And feel free to come back with more info, and to ask more questions.
