Blog comments - Youtube URL's - Keywords :

-

Just a little question, easy for people who build backlinks by commenting on blogs

I want to promote Youtube vids url's by commenting on blogs.
For example, let's take "weight loss" as my longtail keyword.

I cannot put my keywords in the URL because like you know, Youtube url's end by numbers and characters.

---

So, in my Blog comment, do I have to put "weight loss"... :

- In the anchor text ?
- In the comment ?
- Nowhere ?

And the last thing, which is pretty obscure to me,
how Google can "see" the post/comment is relevant to my niche ?
("weight loss" in this example) ?

Thank you all for you help !

i am not 100% sure what you mean but i would go for the anchor text and on the tags in your youtube video

I meant in my Blog comment (I have edited my post)

Thank you
