My website has several videos, mostly product reviews and tutorials. I'd like for these videos to show in the SERPs with rich snippets, but I am hosting them through Youtube. What is your experience with Youtube hosted videos? Do they generate rich snippets? Or will Google always rank the Youtube video over your web page?

I am trying to get my content in the Google Knowledge graph. Everything I've read thus far about Knowledge Graph tells us how to get in for branded terms (e.g. company name or your own name). But I am looking for ways to have my content be indexed and shown in Google graph.

For example, if you search for "mayonnaise for hair" you will see Knowledge graph show us a snippet from an article on RealSimple.com. **How do you get your content to show here? **

I've been reading a lot about SameAs markup, but it seems to only help for branded terms, so companies can have a knowledge box for their brand. But does it help for non-branded keywords?

I appreciate any advice. Thanks.
