I'm working on a website which currently has two different domains pointing at it:
- example1.com
- example2.com
I have read that serving identical content to multiple domains can harm rankings.
The website being served is largely the same with the exception of item listings (think of an e-commerce site) and a few other minor tweaks (title, description, keywords, etc). Depending on the domain used it will adapt to serve different items.
Does this resolve the issue of serving duplicated content across multiple domains thus not harming the rankings?
Or would I be better to 301 redirect to a single domain and go from there?
