I read about SwiftKey after seeing it tweeted as a keyboard alternative for Android users. When I landed on the home page of their website I saw this:
I immediately went to search for their app and paid for it. It took less than a minute to sell me on this product.
I haven't come to any conclusions about how effective it is and I don't know anything about their customer service, but they got me to spend. While social matters, that sale is the ultimate goal. (Keeping customers is another blog post. ;))
How can you make people buy into your product when you have less than a minute? Does your website/landing page/marketing efforts convey that message? If not, you have work to do.
