Economics of the Web Hosting Industry

If I understand economics of the hosts as a web-hosting industry for many years, will their expectations change?

Hosting companies, much like others, decide on the amount of gross income they can help in helping others. The average price of goods sold to most hosting companies (servers on data centers) is around 30%. That way 70% of every dollar contributes to paying staff and other things.

If the company is still trying to grow (and I expect it), then marketing costs will be another 10% or more. However, the cost of hosting the host client is currently the highest in the world. With a key like a "website host", a click of AdWords may be $ 50. Therefore, marketing and COGS (servers, infrastructure) mean that only about 60 percent of each dollar is to pay salaries and other expenses.
