I’m slowly upgrading RW6 sites to 7.2.2 and have come across this issue.
As you can see from the screenshot, the existing Description has been imported and placed in the tags list. Is it OK to leave it there or should I remove it and instead put it into the empty Description box that sits above it?
If you use Foundation, there is a third version: The description in the SEO Helper stack.
I think it is ok if you decide yourself for ONE way to place the description.
Another option is to just do it manually gives total control.
RM actually have a free video on this, but unfortunately the Lance Pollard link with all the tags shown in the video, is dead. However, you can see that information copied from that original link at https://gist.github.com/lancejpollard/1978404
It is very easy to create your own text with the tags and paste into the head area.
@barchard This would be good one for your WeaverTips
Yes use only one or the other other wise you will gererate 2 or more meta tags in your HTML.
Here is a test with Foundation SEO helper, A manual meta tag and the desciption box filled out:
You can see that 3 meta desciptions are generated.
