The problem with simply focusing on volume of backlinks is that you have to focus also on niche-specificity.
Getting backlinks from dropped domains is not going to push the ball forward all that much.
You need to look for other indications of quality.
Personally speaking, I would stop looking at dropped domains as backlink sources.
Instead, I would focus on earning links through better content and establishing better relationships.
But that?s just me.
I look a couple of years down the road, and let?s face it, dropped domains and the backlinks you get from them are
simply just one Google update away from being obsolete.
That?s the gospel truth.
