  • I love the cartoon!

    So what is the best way to avoid duplicate content like you mentioned in the first example?

    I have noticed that happening on my site….

  • Thank you for pointing this out and directing meas to how to avoid, as well as analyze and repair.

  • Great article. Last image is exactly how im feeling!

  • I need to read more on the canonical tag. I can see how blogs generate duplicate content.

  • anyup

    hi see you again . ths for share

  • The SEOmoz Google robot ones are v. good – I’ve seen them used elsewhere before

  • People also forget about little things like making sure your blog posts are only in one category and not a handful.

  • One thing I have noticed with dupe content across multiple domains (due to white lable partner sites) is that Google will sometimes rotates (randomly or algorithmicallyI’m not sure) the display of some of the dupe content results. ie; a search for “blue widgets” will return domain “a” on the first search, and domain “b” on the second search. It will continue to do this for a few hours until it eventually decides which one to display permanently.

  • Should I stop publish my articles on article directories? I used to publish my articles, but now I wander should I stop doing this, because the risk of duplicate content penalty.
