What’s a good ROAS?

Just wondering what a good return on Advertising spend is. I only have relatively cheap products, so my ROAS is I think quite bad 1.7! The clicks, as a proportion of my £2.99 product are very expensive, I imagine it works well for expensive products?

if your product is cheap then ROAS Will be Low. Because the higher the price of your product, the higher PPC Bid. when finalize the product then caution should be taken
