Shehzad,

First off, no I have not used software like this. Now I am assuming that using Backlink Boster is going to be your main link building strategy, so I am basing my following suggestions off of this idea.  Usually, if you are getting a link from a site and it is not getting index fast, there is a good chance it’s a low quality link.  You will not get very much value out of a link that is having a hard time getting index.  So my question for you is, why spend so much time getting low quality links to your site?  You can spend the same amount of time and maybe get 1 or 2 quality links and it will bring much more value to your site. You will get more authority, link juice & quality traffic from the 1 to 2 high quality links.  Now, with all that said I would still be very careful using Backlink Boster, I looked at their site and there techniques look a very automated and spamy (maybe spamy is too strong of a word).  After looking through there how Backlink Boster works page, I would say there is a good chance Google and most of the other major search engines have already flagged majority of the sites they are using in their network as low quality.  If I was you, I would spend my time getting the high quality links from the authority sites in your industry.

I hope this helps,

Cyle

SEMRush is a good source I use; it will show you the sites estimated expense for PPC spend.  I don't know if it can show you how much your competition spends based on category.  I have never tried to figure this out with their tool.  Hope this helps.
