I have an existing site almost 85% of its contents are database driven, Now I want 50 more such sites. I have an Idea of using this site as base site and access this site from different domains. I can keep database different for each domain. All of these websites behave and work as independent sites , except the fact, that these all is actually using a single site with their own database .
Now Is this a feasible idea ? what are the Pros and cons of this approach ? Is there an issue of Google blocking these sites arise ?
I have given one more option of keeping centralized database for sites and keep there code in respective domains.
I am confused as am also a newbie in PHP and web development.
I found some breakthrough here .htaccess RewriteRule: two domains using same server and directory now I have to see about Google issue
Thanks
A big con is the duplication of comments (as mentioned in the comments).
If domain1.com has contains the same, or all most the same content as domain2.com Google gives both sites a penalty which will result in in lower rating. Keep in mind that the same happens if you duplicate content over multiple pages in a website. (domain1.com/page1 having the same content as domain1.com/page2).
If the 50 site have unique contents this won't be a problem.
