Featured offer for FBM seller

I am new to selling on amazon. Out of around 120 products I currently sell, I am the cheapest out for about 90-100 of these. I understand that price alone doesn’t automatically make you the featured offer.

There are however some items where 3 people are selling the same item, but none are featured, as well as ones where no one else is selling except me, but I’m not featured.

Is there a simple way to help become the featured offer?

I know you have a better chance if you: – Use FBA (which is not for me with my already tight margins) – Enrol in automatic pricing (which is also terrible- their recommended price to be eligible for featured offer is around £50 less than my cost) – have a solid buyer feedback (this is pretty non existent at the moment being a new seller)

Do you have any advice that might be able to help me?

Thanks in advance
