Thanks Aussie_Al. I'm trying to compile an IP list to put into an htaccess file or blocks of IPs for my hosting account. Have you seen a good list anywhere?

You'll get fraudulent traffic from every country.

However, some countries will convert to sales much better than others. There are also countries which seem to be a source of lot more tire kickers than buyers. Those marketers who are using Adsense and its counterparts for revenue usually find that there is 'premium" traffic, which is mostly from countries with English as the first language. For some products, Western Europe can also work well.

Google and Yahoo will often rate higher the "quality"or conversion value of the countries that I've mentioned. If they (G and Y) find that to be true it may well pay marketers to consider whether they can focus on those countries, especially for bought traffic.

I notice with a number of my websites I'm now receiving a lot of search engine traffic from Russia and China. That's only an observation, not a criticism. I'm still not sure what the significance is of that shift.
