So this is interesting...
I was going through my analytics and noticed a fairly massive traffic drop. I hadn't changed anything, so I investigated a few different areas before doing a Google in site search.
Like so: site: The Truth About Credit Cards.com | Credit card debt help, credit tips, student debt help, credit advice and credit repair.
And I noticed that after about the first two pages of results, it was all supplemental. Why? Not sure.
These latter pages weren't any different...they were actually older, with PR up to PR5, yet somehow supplemental. I have no idea why, though I assume there may be canonical issues?
I was thinking about blocking the robots from accessing my category and archive pages. But I still don't understand why some pages are supplemental and some aren't. It's just odd that old pages with solid PR are supps, but new pages and posts aren't. Perhaps it has something to do with older pages being indexed on archive/category pages?
I'm baffled...if anyone could share some insight that'd be awesome.
