Questions we get asked regularly about Portobello.
Why don't you have tabs on the product page?
Over the years working on Conversion Rate Optimization for paying clients we have gathered hundreds of thousands of real user sessions showing that only around 1% of visitors click tabs on product pages.
Tabs are useful if you want to hide content away from visitors so they will never see it. If you look at one of the leaders in ecommerce, Amazon, who pioneered the use of tabs on their site, you won't see any tabs on the product page now.
Why do you not recommend showing sharing icons on the product pages?
By analyzing hundreds of thousands of real user sessions we found that product pages without social sharing buttons convert better than those with. Anything that can potentially take visitors away from your site can cause them to get distracted and not complete a purchase.
