There are a lot of link-building SEO tools in the market.

All do almost the same. But you need to be careful where your links are 
being created. You don’t need backlinks from spammy 
sites. What I liked about RankerX is that you can create your own set of web 2.0 PBN sites.

RankerX is good for creating backlinks for Tier 1 sites and money 
sites.
