Best Advice Regarding The Vbulletin Archive?

[boxingscene]

We have a very large forum running over 3.8, and because of that we have a very large archive.

The archive is not really causing a duplicate content issue, as Google seems to know the difference and there are variations in the meta and title tags.

However, I do notice that sometimes Google will index the archive version instead of the full version OR give the archive version a higher ranking.

Also, the archive pages are obviously coming up as being non-mobile friendly.

I was pondering the possibility of just doing a 301 redirect, archive page to full page and turning archive pages off - but because of the high volume of archive pages indexed (hundreds of thousands) - I'm not sure if that will hurt me or help me - or a combo of both.

I see VB.org has their archive still in place and it doesn't seem to hurt them when searching for VB items on Google.
