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

@JennyHalasz
Avoid: • Redirects • Error pages • 1st pages Know: “an application can choose to ignore any improper canonical designation”

Rel Prev and Next
@JennyHalasz
Key Things to Remember: • High Title Match • Duplicate Titles are Fine • Google Recommends View All • SEOs recommend Rel Prev/Next • Do not use noindex

Mergers and Acquisitions – Canonicals?
@JennyHalasz
Copy all old content to new domain
Needs to be almost
identical content,
although you can add new
if desired
Canonical old domain to new
domain
link rel=“canonical” href=“http://new
domain.com
Create banner to explain to users
Hey, guess what, we’re
moving!
Consider using a reference
Welcome, friends from old domain, you’re in the right place.
Create 301s from old to
new
Because now that you’ve completely
confused your visitors, you should do it
again…

Syndication – Two Perspectives
@JennyHalasz
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!

And 6 Months Later…
@JennyHalasz
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.
Chicago | November 12–16, 2012 | #SESCHI
And Today…
@JennyHalasz
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.
Chicago | November 12–16, 2012 | #SESCHI
And 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
