Is there anyone know why the targeted keywords I advertise could not be found on amazon top 10 search pages?
However,it is so weried that it has clicks everyday and even though I increased my keyword bid I still cannot find the ads on the page.
Is there anyone have this similar issue ?

Amazon’s advertising algorithm considers the relevance of your product to the keywords you’re bidding on. If your product listing is not deemed relevant enough or has a low-quality score, it may not appear in the top search results even with higher bids.

The keywords you are targeting might have high competition from other sellers with larger advertising budgets. This can make it challenging to secure a top position in the search results, even with increased bids.
