"Conversion funnel optimization is the process of redesigning, testing, and analyzing the pages of your website after the landing page. This can include anything in your conversion tunnel such as product detail pages (if category pages are used as landing pages), the shopping cart, and the checkout process. Simple changes to your conversion funnel optimization can lead to big improvements in your conversion rate."
