But a lot of blogs don't let you comment or it is really hard to find good blog posts to comment on.
I don't simply want to spam my link, of course.
I want to add a really helpful and valuable comment and point to a blog post from my website that would add more information regarding the topic of the blog post I am commenting on.
I hope you get the idea.
How you do it and how to find the right blogs where I can comment and where I am allowed to leave a link?
