Amazon widget vs buy now buttom

So I was just on YouTube watching some videos from Saledaddy1 when he said that when using the amazon affiliate program it's better to use the "Buy from Amazon" button than an Amazon widget. Is it really true?

Because when I write game reviews or on other products then I could use that but I have written an article about posture and I have added a sub header called sitting and there I put some chairs you can buy on Amazon, I can't use the "Buy from Amazon" button there, can I, I also put some pillows there, under the sleeping sub header. And I won't put the link to that article here because some people will just say that this is self promotion, unless you demand so.

So, should I use the "Buy from Amazon" button?

You can see the buttons here

So, no one is using the amazon affiliate program.

Try both options out and see what converts better. There's no way of saying, and it depends on your niche and your traffic etc...I've had success with the buy now button in the past, but you need to try make it as natural as possible and blend with the site design.

Thanks, I'll give it a try. Got nothing to lose.
