As far as I'm aware, metadata isn't going to help your website get indexed. It only lets you provide some keywords/tags to associate with your page if, and when, your page gets indexed. If you want exposure, you should submit your website to a search engine (
like Bing, for example), or wait until web indexing robots find their way to your page. I'm sure there are ways to game this process and raise awareness quickly but I don't know the details...
But with regard to your original question, the code you've pasted looks okay. At least, from what I can make of it.
