Do items sold through ads stay popular/ ranked even after the ads are turned off? ?

This item costs $13 wholesale, and I’m selling it for $19. The Amazon fee is 15% of the sale price, and the cost per ad click is $0.05.

With a selling price of $19, the Amazon fee would be $2.85. This means my profit per sale is $3.15.

If I run ads, I can afford to spend up to $3.15 on ads without incurring a loss, which allows me to run up to 63 ads while expecting to get at least one sale.

My question is: if I get hundreds of sales through ads and then stop the campaign, will my product maintain visibility and ranking?
