Which seo technique is best to create back links?

Welcome to the forums, @seljamark111. While we’re glad you want to participate, I’d like to ask you to take the time to read a thread in full before replying. We have already explained in some detail why these kinds of links which you place yourself are of little value, and certainly would not be considered the “high quality back links” which @varkeysonia9 is asking about.

It’s really not helpful to repeat what’s already been said, especially when it’s already been explained why those suggestions are not good ones.
