All the Busby SEO Test contestant are not allowed to buy a link, if they don’t have money . But, if you have a lot of money you can start to spent your money. And I hope debate about paid link in this contest are not going to happen again.

Okay, one problem solved. How about Google Paid Link Penalties ?

Google are still keeping an eye on blogs that sell links and review which pass pagerank. And Andy Beard said Google is in a Monopoly Position about this situations. Matt Cutts on his blog write he wants bloggers to disclose that they are doing a paid review of the site or use a nofollow tag to the links which are outside of the actual domain.It’s a few of simple ways :

1. If you buy a paid review, make sure your target blog for advertising not placing any P a y P e r Post, R e v i e w Me or S p o n s o r e d Ads banners. It might be, *might be not 100%* will put you on Google penalty list.
2. Buy a review or link from a related site.
3. And make sure this blog are not just write review posts, or just selling link without content on their site.
4. Contact the website owners personally, ask if they’re willing to sell you a link or some ad space on their site. Google will not detected these kinds of paid links (at least it almost impossible).

And this tips from SEOmoz according to void Google Penalties :
1. Don’t list their publishers or clients publicly
2. Don’t require any specific set of format or code for installation (or change it up very, very frequently)
3. Remain as “patternless” as possible in placement, choice of site, anchor text, etc.

I quote Search engine optimizer Aaron Wall doubts I found in blogoscoped.com, “There are risks if one is too aggressive, but as long as paid links is only a small portion of your overall marketing strategy it should not have much risk”.
