SEO Issue on Powered Domain vs Vertical Industry Websites

[Mansi Padhya]

Hello Guys

Can you help me on following situation for my website.

My company wants to create one powered job board website, they want to replicate this job board on all other 40 vertical industry website as a directory folder like subset of that job board. Such as www.site1.com/jobs, www.site2.com/jobs, www.site3.com/jobs etc.

Those all 40 website will have unique industry news article, home page content is unique, all navigation pages has also unique content but only job folder has duplicate as part of powered domain. So I am wondering that will Google consider as a duplicate pages & penalized those website & demote ranking for all 40 website?

SEO can be possible for all those industry website to achieving traffic from search engine?

Please let me know if anyone has great idea about this situation.

Any reason that the jobs board need to be crawlable? I've never seen job postings pull in a significant amount of search traffic. Put it in robots.txt.

Are you planning to let search engine bots crawl those job boards on all 40 domains? If you intend doing this and expect to get traffic from search engines to the job boards on the 40 websites, I am afraid it is not a great idea :)

Thanks for your reply. Actually all 40 websites are already getting good traffic so we don't want to create new domain for all job board rather than add them to all those website to maximize traffic.
