Hi,
We are designing a web site for one of our clients, and using a home made CMS.
I don't know how this CMS has been built, but anyways, in the end the homepage has a URL format which looks like this : www.mydomain.com/my-custom-url.html. No www.mydomain.com.
Is it dangerous for SEO to have a slug/URL directly on the homepage ? Do you have experiences, cases where it has impacted a site negatively ?
The main problem I expect is duplicate content (with Google seeing both www.mydomain.com and www.mydomain.com/my-custom-url.html as being different pages) but apparently the CMS is doing a 302 redirect from the root domain to the URL (I told my colleague it should at least be a 301).
Sorry if this question seems like basic SEO knowledge, but I really can't find a definitive answer on the subject.
Thank you very much
