A recurring business expense for as long as your web page is published is for managing and maintaining your web site.
It even becomes more of an expense if you do not promptly answer your emails or address issues.
On-line viewers can click away from your web pages faster then you can capture their attention, never mind re-capturing their attention.
Service on the Web is always a well-discussed issue and your business web site has a big advantage only if you take the advantage to provide award-winning customer service.
This also means that components on your web pages should be functional and in good working order at all times.
