The worst possible situation for any business owner must be when an employee leaves taking not only a copy of the Company website but the customer database and sets up in competition.
My question relates to duplicate content.
Whilst database feeds are used by many ecommerce sites and are therefore similar in content, it is rare for a site to be set up using identical url php extensions and almost identical page layout.
From your experience what penalties can the original site expect to suffer at the hands of Google and what steps should we take to avoid these penalties.
Thanks in advance
