Welcome to the Q&A Forum

Hi there, I'd have to know the keywords you were using to see for sure. But I just tested a keyword from your campaign and saw similar results. It's most likely because When you run the report without the http you aren't getting the credit for the canonical tag you have. When you run it for https, you are getting the credit for appropriate use of the rel canonical tag. That's why you're seeing two different scores. If you want to get more in depth, you're welcome to provide keywords here or email help@seomoz.org I hope that helps. Cheers, Joel.
