Our website is really 2 different sites. Same general topic, but 2 logically different areas:
a) One part is highly interactive, lots of stickiness.
b) Second part is a question/answer section which results in incredibly high bounce rate (90%+). Why? Because people usually come in from search engines, get their answer, and are either happy and need to do nothing more, or back out to verify what our information says.
This (b) part is worth keeping because it does provide useful information, and offers references to visitors for future study. It is fairly popular, earns good ad revenue, etc.
BUT, our entire domain and the interactive / sticky part of our site seems to be hurting. Google has slowly dropped us in the SERPs month after month, year after year. Our content is great vs competing websites in all our core keywords, and it makes no sense that our site domain-wide is constantly getting hit.
All that I can think of is that it is the high-bounce area that hurting our entire site, dragging the domain down as a whole.
Questions:
1. Does this make sense? Can a high-bounce, low-time-on-page part of a site damage an entire domain's SERPs? Even for areas that are not high bounce?
2. Assuming I don't want to just delete this part of the site (I don't), should I move this high-bounce part of the site to a subdomain? highbounce.domain.com ? Would google treat domain.com and highbounce.domain,com as separate websites as far as time-on-site, bounce statistics are concerned? Or, would I need to move this stuff to a newdomain.com to have any chance of stopping this section infecting our main site?
Thanks for your thoughts
