Welcome to the Q&A Forum

Good point.  It does have links.  That's a tough one.  How do I salvage the links...

I think I'm going to 301 everything to the home page and start the resource over on a sub-domain.

And just to be clear, you do believe having such a prominent irrelevant page on my site is hurting my ability to rank for the terms I want to...

The traffic doesn't convert so it's of very little use to me.

If I don't want to put the effort into trying to convert it, would moving it to a sub-domain solve my domain level topic modeling problem?

80% of my site's organic traffic is coming through a resource that is only somewhat related.

Does Google think the main topic of my site is terms this resource targets thus bumping the terms I care about to a sub-topic level of sorts?

If this is the case, would putting the resource information into a sub-domain help to solve the problem?
