I am not suggestion this!!! But, you asked for something crazy and this is definitely an "unusual approach".
You have to be a developer to do this. Let's say you programmatically automate a process (write code) of finding videos on Dailymotion in the same niche as your blog.
You write a program that will find, let's say, one thousand videos that have a lot of daily views (like at least 1,000 views per day). That's a total of 1,000,000 daily views.
Then, you write a program that will post a comment for all the 1K videos with your link to your blog. If you use their API, Dailymotion might be ok with this but I would think
it would take longer using the API. If you don't use their API, I think they will ban your account very quickly and delete your posts.
If you use the API and your link in your posts would actually promote your own video on Dailymotion, this would be 100% legit and Dailymotion should have no problem with this. I guess.
I really don't know, you would have to read their TOS.
In this case, you would be sending traffic to your own video on Dailymotion and your blog's link would be under your video player. So if your video is good, users would click on the
link below and visit your blog.
I haven't tried this yet. I only took a very quick look at their API so my post is only a theory. I've been planning to look into this but haven't had time. Of course, this could work
with YouTube as well.
Now that I am writing this I am getting inspired to try this.
