Google’s webmaster trends analyst, John Mueller, recommends do not focus on Link Building.
John Mueller said that webmasters should avoid trying to focus link building, because focusing on link building will probably going to lead to more problems for the site versus actually help the site.
Here is the transcript of the question, “Is link building in any way good?”
That is a good question
In general, I’d try to avoid that.
So that you are really sure that your content kind of stands on its own and make it possible for other people of course to link to your content. Make it easy, maybe; put a little widget on your page, if you like this, this is how you can link to it. Make sure that the URLs on your web site are easy to copy and paste. All of those things make it a little bit easier.
We do use links as part of our algorithm but we use lots and lots of other factors as well. So only focusing on links is probably going to cause more problems for your web site that actually helps.
