If you've been into online dating recently and had no success with responses to your personal ad here is the reason.
In most cases it is because no one actually opens your personal dating profile to view.
Why? Because many people create their dating profile without much thoughts.
They use lousy usernames, meaningless headlines (aka profile subject or profile header) and nothing saying essays about 'myself' and 'my future partner' descriptions.
And no surprise they have very limited or no success at all as a result.
