I am developing a Polymer app at http://alpha.drjoke.com
I tried submitting to Google Index using the Webmaster Tools.
It appears that Google can render my app correctly.
However, it seems that Google is not picking up any textual data. It is not indexing any words from my app. It even complains that it cannot detect structured data and that I should start adding HTML.
Am I understanding things correctly? What can I do to have Google correctly index my Polymer app.
It took a few days, but it now seems that Google can see the textual content on my Polymer site.
