Is it worth switching from HTTP to HTTPS?

[Vars]

I have an established site that ranks well and was wondering what you guys think about switching from HTTP to HTTPS?

 

I know HTTPS is a ranking factor that has a benefit over HTTP, but I am curious as to how much of a ranking factor it might be.

 

Specifically, I have a good number of pages (10-15 or so) that rank #2-#3 for the terms I am targeting.  I also have a good number of pages (75 or so) that rank somewhere after #3, but still on the first page for the terms I am targeting.

 

If switching to HTTPS bumps any of the #2 or #3s to #1 or any of the 1st pagers to the top 3 results then it would definitely be worth the trouble.  I know it's pretty much impossible to guess if I could hope to see those results, so my question is what are you guys doing?

 

Have you switched any existing sites over to HTTPS and seen impressive results?  Did it end up being a bad idea to switch due to a drop in traffic?  Do you implement all your new money sites on HTTPS?  Is switching to HTTPS a waste of time?

I out rank a few https competition with http pages so I'm going with NO, https isn't worth pursuing for SEO.

The only time I implement HTTPS to money sites is when there is some sort of credit card transaction involved. Other than that, I don't see it as a ranking factor!

BTW, Letsencrypt offers free HTTPS certificates.
