Is it ok to use both 301 redirect and rel="canonical' at the same time?

Hi everyone,

I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions.

To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated.

Would it be a problem to have both methods set up?

Is it a problem to have a on a page that is redirecting to another one?

Is it advisable to have a rel="canonical" tag on every single page?

Thanks for reading!

Yeah, I'm with Alan - what works in theory and what works in practice can really vary with the site - if you do both at once and something goes wrong, you won't know which tactic was the problem. Even if it goes right, you won't know which one worked.

Keep in mind, too, that 301s and canonicals have different purposes. They may act similarly for search, in some cases, but they're very different for site visitors. A 301-redirect will actually take the visitor to a new page. A canonical will let the duplicate URL be visited but remove it from search results. In most cases, one is more appropriate to your situation than the other.

Theory: Google is pretty good at figuring things out.

Reality: Google's algorithms, that go through hundreds of changes, tweaks and modifications every year are a soupy mess and their ability to "figure things out" was proven so flawed last year that along with Microsoft and Yahoo, they came up with Schema.org just to address PART of that reality.

Recommendation: Never do anything that could possibly confuse Google if you don't absolutely have to.
