Hi apologies if this is not the right forum for this thread.
I have a website which is related to health and insurance, nothing that could be classed as controversial such as payday loans, gambling etc. however for some reason there has been 3 separate occasions where a domain has pointed their A record at my website. So now I have this situation where three separate, unrelated domains point to my site.
My concern is SEO related, I have seen drops in rankings and traffic across the board. Could it be that search engines are seeing duplicate content? I don't understand what benefit the other sites can have by cloaking my site? Its not as if they are pigging back on my domain name, when you type in my brand name in to a search engine, none of the domains show up.
I have done a whois on each of the domains and contacted the relevant registrar in order to get them to change the A records however I just wanted to understand from anyone who has experienced a similar thing as to why it would happen and what I can do to prevent in future.
eddy essentially already has an addon domain in this sense - assuming apache, i would guess he is missing a ServerName specification or has specified a wildcard ServerName/ServerAlias. (or the equivalent situation if it's not an apache server)
