> How do you host your site?

TL;DR: entry level Virtual Private Server (VPS) per country.

Based on some SEO articles, I decided to go for Top Level Domains depending on target market (.es for Spain, .de for Germany, etc.) so I needed properly geolocated IP addresses for each country. Each server is around 10 USD/month making this approach affordable. I do all operations.

> How do you compare the similar products and aggregate them within your database? Unique identifies etc.

Each product is manually added (using self made web based template) into database basically because of custom description, picture and specifications. Similar products are linked based first on category and then using properties like weight and drop.

This is good advice. I'm going to be building a site and replicating across TLD and IPs like this across countries. My only question is, if you are using the same content (ie, you write content on the blog for SEO) across each site do you run into trouble with Google for copying existing content?

I am sorry I can't provide a reliable answer to this because my english based sites need more traction, but Google (GWT) does not complain as long as hreflang attributes are properly set.
