Unfortunately, press releases just aren't what they used to be. If you're looking for legitimate journalists to notice you and your website, you're probably better off trying other means. Look into what is called "Social PR."

Basically, one tactic is to engage with journalists on their own turf. Twitter is a great place to find and chat with journalists. But be careful; you don't want to "close on the first date" if you know what I mean. Don't try to pitch them a story right away. Build up rapport over time and then go in for the hook.

So personally, I would invest time and money into that, rather than churning out press releases that don't really get seen anymore.
