I am a little confused about what Google means when they say panda will filter sites like content farms, can someone give me an example of a content farm?
That is what I thought, but it turned out that sites like eHow.com is considered a content farm source wikipedia http://en.wikipedia.org/wiki/Content_farm http://en.wikipedia.org/wiki/Demand_Media
A website which invite people to write for their website or invite people for submitting their write ups are called content farms. Or refer this wikipedia page: http://en.wikipedia.org/wiki/Content_farm
basically a site where people write lots of random crap just for the purpose of getting indexed and ranked.
Having 2 or 3 duplicate articles (if your site has 20 pages) won't affect your ranks. The percentage of crap content (duplicate / spun) is what it counts.
Lots of crappy duplicate content. Usually automated website that scraps from article sites like ezarticles.
