For content syndication, let's say I have the choice of (1) a link back or (2) a cross domain rel canonical to the original page, which one would you choose and why? (I'm trying to pick the best option to save dev time!) I'm also curious to know what would be the difference in SERPs between the link back & the canonical solution for the original publisher and for sydication partners? (I would prefer not having the syndication partners disappeared entirely from SERPs, I just want to make sure I'm first!) A side question: What's the difference in real life between the Google source attribution tag & the cross domain rel canonical tag? Thanks! PS: Don't know if it helps but note that we can syndicate 1 article to multiple syndication partners (It would't be impossible to see 1 article syndicated to 50 partners)
