Uploading a video on YouTube with your keyphrase and embedding it on your website will hinder your Google rankings.

False. Uploading a video to YouTube with your keyphrase and embedding it on your website can actually improve your Google rankings. Google owns YouTube, so videos hosted there are often favored in search results. Embedding the video on your site adds rich media content, which can increase user engagement (time on page), a positive signal for SEO. It also provides another avenue for your content to be discovered and can drive traffic back to your website. Conversely, not using video or embedding it poorly might hinder rankings, but the described action itself is beneficial.
