A comment in the homepage’s source says:
IMPORTANT! LOOKING FOR THIS SITE’S SEO CONTENT?
This site's SEO content, such as meta tags and headers, is not here.
This is because search engines, like Google, actually crawl the site's homepage via http://www.lizavoronina.com/?_escaped_fragment_=.
Internal pages, like “?????”, also have their own special search engine versions, for example: http://www.lizavoronina.com/?_escaped_fragment_=about1%2Fc1fz3
If you’re looking for this site’s SEO content, that’s where you can view it.

So those search engines that support the
?_escaped_fragment_= alternative (for example, Google) will be able to access the content.
?_escaped_fragment_= support will not see the content.
