Because you have a new product in a possibly over-saturated category. Gone are the days when you can just create a listing on Amazon and watch the buyers find and buy your product. You’ll need to do some off Amazon advertising to get buyers to Amazon. Once you have sales, you’ll move closer to the first page.

I had a product I spent several hundred dollars on ranking it to the front page. Than suddenly somehow it just “de-categorized” itself and I had to talk with the catalogue department to even make it visible. Sadly it has never returned to any of the 7 pages and all that money for ads was for nothing. One of the biggest problems is the indexing is terrible, you can search for a coffee pot and get 10 different things that aren’t even related to that search on those 7 pages.

No puedo ver mis productos publicados , solo se ven si los buscas por ASIN o nombre de vendedor. Como puedo hacer para que se vean mas fácilmente ?

The All Departments search provides a limited number of results in each category, by design,

You do not know how many sales your competitor has made, nor do you know why his search placement is better than yours. You can assume Amazon has a reason to favor his product over yours.
