Have you ever wondered how the Chinese Great #Firewall might impact websites hosted outside of #China? That is one of the important questions when looking at #SEO for #China.
I used the German World Rankings list of Searchmetrics and picked randomly 2500 domains from the Top 100K visible domains in Germany. I identified with some help from Thomas Rudolph the homepage URLs returning a status code 200 in Germany.
Those URLs I crawled from China using Screaming Frog with a Chinese local IP, to find out how these Domains can be reached.
Nils Horstmann, I think that was the kind of statistic you wanted to look at the other day .
Here is what I found out (as you can not see numbers in the chart):
- 92.4% of these domains were reached without any problems
- 5.5% of these domains could not be reached because the connection timed out (or DNS look up failed)
- 2% of these domains could be reached, but the status code (which was 200 checked from Germany) was either redirecting, or refusing connection (403 or similar)
