I dont believe you have aproblem if you havea bit of duplicate content, google does not penilize you for duplicate content, it just dosent award you points for it.

you mean a product name for each image, or all images on the page have the same alt text?

either would be better then none, but obviously better if they are unique.

This would not be seen as spam at all. (IMO)

I also dont think that same ip or same c-block is suuchh a worry.
i have my own servers with only one IP, and links from the same ip seem to work as well as any other.
Obviously if 90% of your links came from the same ip that would ring alarm bells.

Take discountasp for example, a very large hosting organization all on the same ip number.

They can do this stuff in english,, but i dont know how far they have got with stuff like this in other lingos

Obviously others are giving different advice, but i would leave it, but i would think about how google sees the subdomain, is it obvioulsy part of the same site or not, is their plenty of linking

One example i have is where the root home page ranked very well for very comnpeditive keyword that was a keyword on a sub site the only mention of the keyword on the root home page was in the link text to the sub site.
In fact the home page ranked well for all subdomain keywords

If google wants good quiality results they would easly handle this.

People were paying riduclus prices for houses here in Western Australia, now rthey wish they didnt. People tend to follow each other when spending money, if he is spending that much then its ok for me to do so, atitude.
This is how we get bubbles.
Having said that i dont know any other stats you could use, but I do think description is very important for conversion.

I have to disagree. google are much smarter then this. If you have a site with subdomains that is presented as one large site with sub sections they will see it as that. If it looks liks the subsites are not well connnected they will see them as seperate sites.

I have found there is no difference between subdomains and sub folders, If anything the advanatge of being able to put keyword in the subdomain gives subdomains the edge.

Of cause link between them well. One other tip I can give is keep all images and css and js files on root domain, any one at google noteicing this would think this site is connected., I would wouldent you.

You mean we aren't all staying at Rands place?

I just worked out that WA stands for Washington, not Western Australia, seems i wont be comming.
