Hi @Seller_1LO4TdQO9wbDa,

Just coming across your post here! Wondering if you've seen any improvements to your ROAS in the past month or if you are still searching for some answers. I wanted to provide you with some of the tips and resources I like to share when I see this question come up:

1. First, make sure you have a really good understanding of effective targeting practices. Check out this guide on effective targeting with Sponsored Products as well as this guide on three simple tips that can help improve your sponsored product campaigns.
2. Next, ensure you are constantly optimizing those targeting segments and keywords to ensure your campaigns are capturing the most relevant search terms and shopping trends. I would suggest checking on this weekly to see if any keywords need to me removed or updated, or if you should decrease or increase any bids. This help page on optimizing your keywords has a good list of best practices.
3. I know you mentioned you have already checked your listing, but be sure to view listings from the customer perspective. Is there anyway they can be dressed up to entice customers a bit more? This guide on improving your product listing has great advice on what can be done to give your detail pages a little more pizazz.

Let me know if you find any of this helpful and be sure to give us an update on any changes you may see in your ROAS.
