Does the Bold Custom Pricing app prevent wholesale prices from appearing in Google search results, and if not, what solutions are available?
Custom Pricing does not prevent prices from appearing in Google search results. The effectiveness of hiding prices depends on the discount version used; some versions may show prices in Google while others do not.
