How to embed a Youtube video on a website?

Question

Search Engine Optimization

I plan to add a video from my YouTube channel to the site, but the problem is that there are about 150 selling pages on which it needs to be added, the same video.
Can such an amount of the same content, albeit on different pages, spoil the karma?
How to do it correctly so as not to harm the SEO optimization and does not lead to a decrease in the positions of these pages? So that the weight of the link is transferred / not transferred?

Answer 1

The video is inserted into the site through an iframe. So? So this is a normal div. After all, your logo or menu is also repeated on all pages. It's not text.
