Best Paid Back-link Services?

Hey guys, this is my first post, what's up? =)

I am new to affiliate marketing and I have made 3 micro-niche product promotion sites in the last month, which are chasing very specific, relatively low-competition keywords. I feel like I am in the Google washing machine with my SEO. I went from page 1, to page 3, to page 2, disappeared completely, back to page 3, page 2, and disappeared completely for one of my sites. All I have done so far is attempt to configure decent on-page and off-page white hat SEO. I have created some dinky back-links on around 20 do-follows, that I really don't think have helped much.

For seasoned veterans of the SEO game... Which paid, quality back-link creation services do you recommend for my sites? I really don't know anything about these services, and I don't want to get ripped off. I am willing to pay, but my budget is kind of small. Let's hear it!

Thanks!

Your sites are still relatively new, so I'd say the best direction for you to go would be slow manual backlinking on relevant sites with at least 3-4 different anchors + raw URL rather than some services that offer 1,000's of backlinks for like $0.50 Also, be patient and don't over-analyze the SERP and go crazy if your ranks dance. It can take months to see good improvements.

Feel free to PM if you have any questions.

There are various ways in which you can get back-links and they can be categorized into two ways: paid and non-paid. According to good SEO practices, non-paid back-links are more favorable, which you can do with original article writing and submitting, free directory submission, forum posting, blog commenting, few classifieds, guest blogging etc. Apart from this, there are certain link and article directories which would ask you to pay to include your link. It is advisable to use the non-paid methods over the paid one.

First thing I'd do is ignore any advice to do wholesale spam backlinking, and discount anything else the person that suggests it says. Penguin has changed everything, and some dinosaurs are staggering around the Cretaceous Epoch, and they don't know their walnut-sized brain has been blasted out the base of their skull by a .50 cal. And some dishonest scammers are willing to deindex your site for twenty bucks worth of backlinks.

Second, start reading-up on "Link Pyramids, and start planning your Tier 1 links. Safe sites, like Web 2.0. Even Facebook. I once saw a massively spammed Tweet give a large hotel in France the #1 position. Don't aim any crap at your money site. Don't aim crap at Tier 1's that will kill you if they get de-indexed.

Always do fastest links first, slowest last, cheapest first, most expensive last, safest first, most-risky last. No point in spending more time, money or taking more risk than is necessary.

Finally, do an exhaustive analysis of any competitors. Put your links on the same pages where their links are. This does two things: 1) Dilutes the pages juice, and 2) Gives you an equal share of what they get. They lose, and you win.
