Most Profitable Doctype

This is one for your Information Technology department or your webmaster.

The first line of every web page should be starting with a “doctype” tag. We did the study to find out which doctype tag was most associated with profitable sites and least associated with unprofitable sites.

Here are the scores:

Score: 100% | Grade: A+

!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”

The answer to this one seems obvious. The 2nd place answer isn’t even acceptable in this case.

Is your IT team or webmaster up to coding XHTML 1.0 transitional code?
