I am working on a couple of landing pages for a client where once you purchase a product, it automatically re-directs to another page to upsell to another product. I am using the plugin Woocommerce (as shopping cart plugin) on the WordPress platform and I was wracking my brain on how to make that happen. In theory, I think it is great as a way to lead people to more important pages on your website. So, just a little bit of digging and I found Woocommerce Redirect. You can use it in various different ways, such as if you have a membership website. After payment, you can re-direct your client to a new page on how to log in and use the membership area. You can direct people to sign up for your newsletter, after payment. You can do what I am doing now, lead people into new pages with related products for purchase. I think it is pretty cool.
Good design is one thing, but you have to make the website work to get sales. I think this plugin makes that much easier.
