The best way of allowing potential buyers to find out whether a used product I am selling would be the right size for them would be to direct the potential buyer to the website for the manufacturer of the product.  I have worked out that I cannot insert a link without violating eBay policy.  Listing was hidden when I added the https address.

Am I allowed to tell people to use a search term on Google which will take them to the sizing page or will this also lead to my listing being suspended?
