My website has two main sections of content to it. For illustration purposes let's call them foo and bar.
example.com/foo 60 pages example.com/bar 25 pages
Section foo isn't doing very well. The content was much harder to rank for and they're getting close to 0 visits on all pages. The pages have been live for over a year and I don't anticipate them getting much traffic anytime soon.
Section bar on the other hand is doing pretty well. It's a few months old and is seeing promising traffic. 99% of my site traffic comes directly from the bar section of my website.
Should I be concerned that the poor engagement from foo might negatively impact the bar section of the site? If so, what options do I have if I'd like to eventually build up both sections of the site?
