A very important aspect about web pages that collect or manage user information is: SECURITY.
This includes also the typical contact form that collects several personal information details that could be exposed to malicious hackers that could be sniffing around.
Over 174 million records where compromised in 2011 by hackers around the World, as stated by Verizon (http://www.verizonbusiness.com/resources/reports/rp_data-breach-investigations-report-2012_en_xg.pdf).
Make sure your web page is a safe and trustworthy place where your customers can buy and surf safely by having an SSL certificate installed on your web hosting account, securing your connection by a 256bit encryption.
Remember that you need a dedicated IP address to be able to install a SSL Certificate on your web hosting account. Once you’ve got your dedicated IP address, buy the SSL certificate and install it through your cPanel control panel.
