Search engines count links as votes of quality. They primarily want to count editorial links that were earned over links that were bought or bartered. Many paid links, such as those from quality directories, still count as signs of votes as long as they are also associated with editorial quality standards. If they are from sites without editorial control, like link farms, they are not likely to help you rank well. Using an algorithm similar to TrustRank, some search engines may place more trust on well known sites with strong editorial guidelines.

Search engines like to paint SEO services which manipulate their relevancy algorithms as being unethical. Any particular technique is generally not typically associated with ethics, but is either effective or ineffective.
Some search marketers lacking in creativity tend to describe services sold by others as being unethical while their own services are ethical. Any particular technique is generally not typically associated with ethics, but is either effective or ineffective.
The only ethics issues associated with SEO are generally business ethics related issues. Two of the bigger frauds are
- Not disclosing risks: Some SEOs may use high risk techniques when they are not needed. Some may make that situation even worse by not disclosing potential risks to clients.
- Taking money & doing nothing: Since selling SEO services has almost no start up costs many of the people selling services may not actually know how to competently provide them. Some shady people claim to be SEOs and bilk money out of unsuspecting small businesses.
As long as the client is aware of potential risks there is nothing unethical about being aggressive.

Those updates were named Google Dances, but since Google shifted to a constantly updating index Google no longer does what was traditionally called a Google Dance.

Link which references another domain. Some people believe in link hoarding, but linking out to other related resources is a good way to help search engines understand what your site is about. If you link out to lots of low quality sites or primarily rely on low quality reciprocal links some search engines may not rank your site very well. Search engines are more likely to trust high quality editorial links (both to and from your site).
