FBM listings treated differently?

Hey AMZ bro’s and sisters:)

My niche is very competitive (nutraceuticals) and my product isn’t not irreplaceable/unique, so I created a listing 5 days ago and decided to start as an FBM vendor, thought it’s always good to fix the errors and work on the listing before/if we go FBA. The challenges I face : 1) Can’t find my product by the brand name + product name, which is unique : abcd bang caffeine (for example). 2) My ads get no impressions : tried all kinds of bidding and set cpc at x2 of the suggested bid. 3) We got Featured offer score 100% 4) Images, keywords, bullet points are all there.

Contacted amz seller support, ads support and keep getting some vague/generic responses.

Since the market is oversaturated, do all FBM listing get treated like this or there’s something we should look into?

Any advice would be greatly appreciated
