We have loaded product videos on youtube for our e-shop (short videos showing product details) They are loaded through embed in our e-shop with specific product. With each video (in description part) there is a link for homepage shop inserted in this form
http://domain.xx/.
Youtube automatically inserting "nofollow", but we can see those references for example through webmaster tools.
Is there a possibility to have negative effect to SEO, if there are lots of references comimg from youtube? We are talking about hundrets videos.
