Backlinks Question

So,

Let's say I have 50 web 2.0s and I want to blast the mother loving god out of them.

What's the best way to get those backlinks indexed? 

Indexification does not work the way it used to, will gsa seo indexer do the job or is there a better way?

Thanks

@khaos88 build another tier pointed at them.

@viking my gsa is creating 15k links, I cannot tier those 15k links that would be madness
