Nick Roshon has an excellent post on the difference between how Google & Bing handle the canonical tag, something non of us really noticed before until he pointed it out.
The key differences are two fold:
(1) Mass use of the canonical tag and
(2) Canonical tag pointing to itself.
How does each engine differ?
(1) Google doesn't care if you use the canonical tag on hundreds or thousands of pages, where Bing says they will trust the tag less if you do.
(2) Google doesn't care if you link...
