Canonical? Source in Footer? Duplicate content issue across sites

Hello there,

If there are URLs that contain the same content, one should have a canonical to the other.
Exaple:
Both pages with the same content
abc.com/article-moz
abc123.com/article-copy-moz <-- this one must have a canonical to abc.com/article-moz

Plain simple.
Or just deindex abc123.com and there will be no duplicate content issues.
In my experience, stating "source:abc.com" didnt worked, that was a few years ago. Cant advise against using/not using it.

Best luck.
GR.

Hi belton

It's perfectly OK to do cross-domain canonicals which is essentially the same as saying source:. What you are actually saying is that these two pages are the same as each other, don't rank that one, rank this instead. so for example:

abc.com/page1 has a duplicate, abc123.com/page1

Put this code on abc123.com/page1

rel="canonical" href="abc.com/page1" />

Google will likely not rank abc123.com/page1 and only rank abc.com/page1.

The result in my experience is that abc.com/page1 will rocket northward in search now you have taken the duplicate away!

I hope that helps,

Best Regards

Nigel
