Welcome to the Q&A Forum

I'm currently doing a backlink audit for our site with a LOT of backlinks.

Some of the linking sites are legitimate business websites in our industry who have linked to us for a totally legitimate reason (we have good content!). However, these businesses themselves have a spammy backlink profile—that is, the only sites linking to that site are obvious link farm sites.

Here is an illustration:

spammyseolinks.com; payforseo.xyz; blackhat.ru   ==all link to==>   legitbusiness.com  ==links to==>  mysite.com

Should I disavow this backlink? I guess it's not really giving me much SEO worth since it surely been branded a spammy junk domain, but then again, it's a real website that we've earned a link from because we're doing stuff the right way. Is it hurting or helping me?

My company's site has a large set of pages (tens of thousands) that have very thin or no content. They typically target a single low-competition keyword (and typically rank very well), but the pages have a very high bounce rate and are definitely hurting our domain's overall rankings via Panda (quality ranking).

I'm planning on recommending we noindexed these pages temporarily, and reindex each page as resources are able to fill in content.

My question is whether an individual page will be able to accrue any page authority for that target term while noindexed. We DO want to rank for all those terms, just not until we have the content to back it up. However, we're in a pretty competitive space up against domains that have been around a lot longer and have higher domain authorities. Like I said, these pages rank well right now, even with thin content. The worry is if we noindex them while we slowly build out content, will our competitors get the edge on those terms (with their subpar but continually available content)? Do you think Google will give us any credit for having had the page all along, just not always indexed?
