I own Scapebox and have used it a few times to create 'backlinks'.
One might consider if polluting somebody else his blog post is a nice deed and useful in itself. Especially as it's already polluted by 100 other people.
I've seen no improvement in ranking. I think getting backlinks by link exchange or other means is a better (and harder) way.
I think the only ones believing in the system are the sellers of these backlinks.
@above, I like to know the way how you create these backlinks and see reviews of people who have really saw ranking improvements with a $3 wonder.
MAIN purpose of scrapebox, is scraping for sites, not blasting away links.
It serves to you, and what you do, is what you get. If you got no results, it's not because scrapebox sux, it's because you don't understand it's main purpose. And that is, finding related sites in your niche, or finding your competition backlinks, and trying to outrank them. You can find TONS of fantastic places you never heard of, that write in same niche as you, which might be interested in either link exchange, or your useful manual commenting. It's easy to check PR of that post, sort lists, analyze sites alexa ranking, check nofollow, etc, etc, etc...
Blasting tons of links as comments to wordpress blogs is completely useless. Wordpress comes as nofollow by default, so, any link on wordpress won't give you anything. Also, it comes with Akismet, so, most of your spam links won't be approved. Same goes for blasting trackbacks. Today, you will blast 10000 trackbacks that you paid 3$ . And, next day? and day after that? Well, google sees natural spreading of backlinks different than you. It starts from few sites, on the top, with high authority, and spreads across the internet, in it's natural shape, when something is interesting.
Formula is, the more backlinks you have, that no traffic is coming from them, worse.
So, get only FEW high authority links as direct links toward your site. Because, your traffic should come from there, and links should spread in natural fashion.
You simply DON'T blast away YOUR MAIN site. It's the worse thing you can do to your site. Tons of useless links, pointing toward your site, and no traffic from them? You seriously should stop thinking that googles algorithms are written by stupid people.
Social networks are what you are looking for, as direct backlinks. But those, if not done properly, won't bring you any traffic. You have to find, where people are going,and what they want, and drop a link there, like a bomb. When you start receiving traffic from that link, google will know that, check keywords you used, compare it with the content on your site, do it's math, and push you up, or down in SERPS. This can be in range from one or two spots on 100th page, from jumping all 100 pages, and kicking on 1st page, for your targetted keyword. Also, this first kick is just testing, google want to see natural flow of backlinks. He will give you 2-3-4 weeks, to see backlinks pointing toward your site. If you get traffic from google, and no backlinks at the time he's sending you traffic, iG will kick you back where you were. If you start getting backlinks, as a natural result of these events, he will rank you even better. That's how you get in 1st position in google for your keyword. I hope you realize how this machine works for you now.
So, it goes, you drop link bomb (not tons of links, only links that will bring targetted traffic to your site, this is how you start), to where people are, you get traffic, google ranks you better, you get natural flow of backlinks, because, people like what you wrote, and link back to you. According to your traffic that google sends you and backlinks you get, google ranks you better or worse, you get MORE traffic, you get MORE natural backlinks, better SERP results, again more traffic...etc...
Btw, these are secrets, that people sell on some forums, for hundreds of bucks, as ebooks.
Oh jeez, I hope you understood how this works, and this spam madness stops.
All it matters, is that your CONTENT rocks, and information you are sending is not crap.
That's why they say: "Content is the king"
Your content will pull in more backlinks if it's valuable. You just need to give it a GOOD kickstart.
When you build all around this formula, you will see why good design is important, why speed of site is important, and how everything fits in it's place in perfect order.
