Does anyone have any thoughts about why my client's website is banned from Google?

We had to set up several other domains like:

to still make sure that we receive the traffic since our site doesn't seem to come up in most searches. I've done a very limited amount of SEO for them, which has helped, but I still want to make sure their main domain starts coming up again - right away if possible.

FYI, should be coming up #1 for keyword "axtell" and #1 for keyword "axtell puppets". They get an avg. 10,000 - 12,000 hits per month, which is probably significantly more than any of the other search results.

Thanks for your help.
