alt tags for embedded video?

Hi myinvite4lockerz

I did a bit of digging around and came up with this possibility. I don't know if this will really make a difference or not in terms of your SEO but it may.

For YouTube videos, try replacing the word "movie" in the name tag and insert a keyword rich title - a short description of what your video is about.

I hope others may be able to chime in with their thoughts on this or have alternative suggestions.

No. No.
That is not what alt tags are for.
They are accessibility measures, for screenreaders and the like.
They are not for you to play about with damned SEO; they are for your users to hopefully be able to understand what your content is.
Stop misusing and abusing them.

Hello StopRuiningThings

You are correct that alt tags are also used for allowing visually-impaired visitors to access websites. However, it's common sense (and best practice) that alt tags at the same time serve purposes to improve the SEO performance of a website. On this blog you can watch a video by a member of Google who explains how it works. There are multiple other articles on the internet which support this view. So we are right to recommend it this way to our customers and to say that the information given above from your post is correct.
