Massive drop in sales

Last April I sold 15 items and I have only sold 4 items this April. I noticed a drop in sales running from January through to now and traced it to drop in Amazon Sales. I am now trying to figure out what happened.

It’s not emerging competitors or bad feedback. I can only think maybe something has been changed in Amazon Advertising. I heard there was a drop in sales overall in the UK.

Anyone experiencing something similar?

One possible reason for the drop in sales could be changes in Amazon’s advertising algorithms or strategies. They frequently update their advertising platform, which can impact the visibility and reach of your products. Check if there have been any significant changes in the advertising options, policies, or costs on Amazon.
