This is probably an obvious and logical statement but Gary Illyes of Google felt the need to post it on Twitter this morning. He said, "did you know that HTTPS URLs in a duplicate cluster have higher chance of becoming canonical?"

This means if you have these three URLs in a duplicate cluster, Google will more likely pick the HTTPS version:
- http://www.a.com
- https://www.b.com
- http://www.c.com
In this example, if all three are in the duplicate cluster, Google will more likely pick https://www.b.com because it is HTTPS.
Why? Because Google now tries to index HTTPS by default.
@pedrodias correct
