Don't Participate in Link Farms
The emphasis placed on inbound links by search engines led many website owners to participate in link farms in an effort to bolster their rankings. This technique is not as effective as it sounds. This is because many search engines weight inbound links based on the quality of the website providing the link. Link farms are not considered quality websites by search engines and therefore these inbound links will be much less helpful than links from other top ranking websites. Submitting your website to link farms can be incredibly time consuming and does not reap significant benefits in rankings.
