May I suggest investing in an SSL certificate for your website? I find it really hard to really trust if that's your contact information ;)
Not OP, but I don’t have certificate on my personal web site either, and I don’t think I need one. > find it really hard to really trust if that's your contact information Because Google implemented warning in their web browser, and you comply without understanding their reasons?

Lots of commenters have raised good points and pointed you to instructive resources on the subject, and you've quite selectively ignored the best ones. Please take a moment and withhold the assumption that we've all been brainwashed by Google, and consider that other people might know something you don't.
