You will not be able to advertise your items if you are not winning the buy box.
In order to become eligible to win the buy box you need to be selling on Amazon for at least 90 days. After this time eligibility is based on a number of factors including pricing, availability, fulfilment and seller metrics.
I would recommend that you review the following help pages to get more information:
[The Buy Box|Amazon].
[Seller Performance Measurement|Amazon.co.uk Help].
[Customer Metrics Overview|Amazon.co.uk Help].
I hope this helps but please do let me know if you have more questions and I will try and help
