Are you confident your site will perform when it goes live?
Poor performance equals poor user experience. Poor user experience will lose you sales.
In the digital world, speed is everything. Information must be instant. Gratification immediate.
Customers use the internet for speed and convenience, 24x7. They are not patient and they will make snap decisions. Your site must consistently perform to meet your customer's needs or they will go elsewhere.
Don't hit the headlines for the wrong reasons. When your site goes live have confidence that it will be able to handle the number of users and will not crash.
