What are link farms?
- Any indiscriminate link exchange, particularly when they are automated
- Websites that encourage links in, in exchange for something (preferential treatment etc.)
- Websites that manipulate PageRank by blocking a search engine's access to link exchange pages
- Link exchanges. Reciprocal link exchange, when done properly, is actively encouraged by Google
- Link Bait. Encouraging people to link to you because you have interesting content is a key SEO tactic
- Pages that link to lots of other pages. If you have an authority page on the top 100 Irish Dancing websites, then that page is not a link farm and could easily become an authority on your topic.
