Much has changed over the last year on the use of Paid Links for SEO. Google has started to penalize domains that they find to have paid links and have invited webmasters to tattle on their competition?
Because Google’s algorithmic formulas lean heavily on linking, they don’t have so much control when people use paid links and have declared that it is ‘unethical’.
Personally, I don’t see much of a difference between paying for links on paid directories (which is considered ethical), and buying links on other domains. Everyone is allowed their own opinion and no doubt the debate will continue regarding whether seo link building is ethical or not.
In highly competitive markets, it can be extremely difficult to get high rankings without using paid links because Google and Yahoo! place a lot of value on relevant, high PR one-way links. A common term is ‘renting a link’. While there are a few services that offer to sell a permanent link, the vast majority of links are rented on a month-to-month basis.
