Problem for my web site?

When I set up my web site I was unable to use my chosen domain (which refers to one of my products) for a time, and instead used a free domain which I got with my hosting plan. Then there is the web site for my company which I also use.

All three point to the same web pages. Within the site I just use relative address, like "images/Gallery/Gallery.html" at the moment. Although until recently this was also mixed up so that people could come to one web address and end up at another.

Now it occurs to me that this is going to completely stuff my google search ratings. True?

Whats my best solution? Go back to the people linking to me and get them to use one address?

My sites are modartis, artisfaber and reinforcementsbypost dot tom.

Thanks for your time.

You may get a duplicate content penalty and you have all three sites competing against each other. I suggest creating different content for 2 of the other sites or have the 2 redirect to one.

Two of these domains are 'parked' onto the third domain. I tried a redirect just now and it put the whole site into a loop so it failed to load!

Do domains parked in this way count as duplicate content and compete for ratings?
