Automatic backlinks.com .. This looks like a good service anyone working with it ?

You are risking de-indexing by participating in a link exchange system. Google hates these type of 3 way exchanges probably more than any other type of link building. Not to say it won't work but i'd be very careful with it.

are you promoting your link in-directly?

Generally, I've found any site I've put in there gets penalized because they have a very clear footprint created by the php code. It is good for passing PR though.

No way would I allow external links to be automatically posted on my money sites internal pages, that's crazy!

However you could setup a dummy site with existing PR & use it to scrape keyword anchor-text from competition in popular IM niches, let the competition do the keyword research then they'll automatically send you the keywords, lol (that would be funny).

Don't participate in link schemes designed to increase your site's ranking or PageRank. In particular, avoid links to web spammers or "bad neighborhoods" on the web, as your own ranking may be affected adversely by those links.

Don't use it. You are risking your blog/website being banned. This kind of backlinks are VERY LOW quality, because of the high number of OBL's they have

Emm i bought $10 worth of links and got my links placed on PR2 PR3 pages and i`ve just been looking at the links i really cannot see a problem with them they look tons better then high PR blog comments do you guy actually have experience with buying links with this service or are you just thinking its a bad idea with the link exchange side ?? If anyone wants to see the pages my links got placed on i`ll send the url in a PM

Emm yeah i can see not too many folks are keen on this service although many of you are just looking at the link enchange side of the service which just so you know you actually have to review the site where your link will be placed AND review the site who`s link will be placed on your site also no two sites will inter link your link will not go on a site linking back to you.

Anyway like i said i didn`t go for the link exchange i bought $10 worth of links just to see where my links would be placed i then had to choose the top level domain and the topic of my site so my backlink was placed on site with relevant content. After checking the results that came back i was really suprised the links where placed on a site with a very relevant theme to my own site low OBL and on page PR 3.

You have to be careful these days with your money site but this service creams any of the WSOs i`ve seen of late and most seo services

I`m not saying its good or bad really i dont know and you have to be so careful now but i will say i`m pretty impressed

As someone who has actually used the service (not like everyone else here) I found the results to be rather mediocre.

I had a test site where I pointed about 30 PR3 links to a fairly low competition word and I got minimal serp movement. Maybe I needed more, but if you are buying credits (as in your case) that's already a $100/month + commitment.

The idea is good, but it seems the value of blogroll links has been diminished. I am still "letting it ride" as I am using credits from a large site I don't use any more that has a lot of inner PR pages so essentially it is free for me.

I don't find the sites to be of great quality but they are not low quality either. The system tells you exactly where your links have been placed so you can check out the site itself if you are concerned. Right now though so far not impressed.

Interestingly the keyword i spent the ten bucks on a few days ago has just jumped from number 28 to 15 in the SERPs nothing mind blowing i know just saying !

Might spend another $10 and see what happens

Link exchanges are so 2004
