More and more site owners are concerned that they might be penalized accidentally or overtly because of duplicate content. If you run mirror sites, will search engines ban you? What happens if you syndicate content through RSS and feeds? Will other sites be considered the "real" site and rob you of a rightful place in the search results? This session will take a look at all the various options available to address duplicate content including:

301 redirect
302 redirect
Canonical tag
Author markup (schema.org)
Rel next and rel prev tags
Deletion of duplicate content

  10. 10. Chicago | November 12–16, 2012 | #SESCHISyndication – Two Perspectives I heard about this thing called the Internet. I think I could write about gardening on there and people would publish my articles! I bought content from a lady who gardens. Now I can rank for “gardening” without lifting a finger! I think I’ll have another drink! @JennyHalasz
  11. 11. Chicago | November 12–16, 2012 | #SESCHIAnd 6 Months Later… I’m getting pretty well known for my gardening articles. I think I should start my own website! I’m ranking for everything that has to do with gardening! Life is good. @JennyHalasz
  12. 12. Chicago | November 12–16, 2012 | #SESCHIAnd Today… I sure am glad that site added rel=canonicals to my content. My site is doing great! I wish I hadn’t added rel=canonicals… that lady’s site is outranking me for everything about gardening. @JennyHalasz
  13. 13. Chicago | November 12–16, 2012 | #SESCHIAnd the Point Is…• Duplicate content is a universal problem• There are no easy fixes• Rel Canonical is a patch, apply with care• You’re probably doing it wrong• Rel Canonical is not a good solution to syndication
