Can template make blog not index by Google?

"We do not detect any structured data on your site."
"If Google understands the content on your pages, we can create rich snippets?detailed information intended to help users with specific queries."
is it because of template?

Roxie,

There could be a lot of reasons why you are receiving this error message. It could have something to do with your markup, a programming error, incorrect or misleading markup or something of that nature. Google has a troubleshooting page that you can use to try and figure it out.
