I run a large, busy forum, lets call it Forum A. It ranks at the top of google for its niche.
I've bought a smaller forum, lets call it Forum B. It also ranks at the top of google for it's niche.
Forum B's niche is a sub-niche of Forum A, which is why I bought it.
I want to combine Forum B into Forum A, and then redirect the Forum B URL to Forum A URL.
Is there a method I need to take to ensure that Forum B's niche remains at the top of Google rankings? Or do you think Forum A will also rank at the top now for Forum B's niche, as it now has all the content?
Clear as mud I expect!
