Let me be straight with you, any backlink that you build should meet the criteria below and these are the only type of link you should be building to your site.
They provide the most bang for buck in terms of passing authority and rankings to your site and will help to accelerate the success of your site.
We can break down the perfect backlink into 5 key elements-
#1 – Site Authority
One of the strongest signals to look at is the authority of the site & page a link is coming from.
So for example a link from Wikipedia or a leading blog in your niche is far more powerful than a link from a newly registered domain.
The perfect backlink always comes from an an authoritative domain.
#2 – Relevance
The second most important thing to consider when defining the perfect backlinks is relevance.
For example if your site is about dog training, you want links from sites & pages that talk about dogs, pets or animals in general. You could even go broader by crossing over to home and family niches.
