Banner slider is a premium real estate of any website. That is the first thing that users sees and search engine crawls. We implement and recommend a good banner slider like Revolution slider. This allows you to have text overlays and embed call to actions. Both are very important as text can be crawled by search engine and with right call to action you take the user directly to part of the funner and enable goal conversions.
One Page Checkout
A One Page (sometimes called One Step) Checkout implementation on eCommerce websites reduces the number of steps in conversion. It shortens the funnel, increases conversion and reduces cart abandonment. When we replace standard checkout with OPC, we loose functionality to save abandoned carts as prospects. These prospects can be 'incentivized' later to complete transaction. It is recommended to implement save prospect on minimum data entered in tandem with One Page Checkout. We have written a blog article on it which explains OPC in even more detail.
We are eCommerce/Magento implementation experts and have consultants who can help you implement features like this that will impact your topline.
