What is the very best software to build links with?
 

I bought IBP a few years ago but it works slowly.

Excel? :upsidedow

do this in private... google has access

Scrapebox? It's generally seen as a blackhat tool, but I've heard that it has some practical and time saving tools for white hat strategies.

nothing .......

You can build some edu gov backlinks see sig for lists but I wouldn't be putting your pride and joy thought auto submitters. Great for some old static sites domains but build your adult links by hand.
