Method to find out how many sites are active on new gTLDs

New gTLD were launched nearly one year ago, and domains started to be purchased 6 months ago. How many of these domains actually run websites ? It is difficult to say, and can be confusing.

Google offers a way to search for a specific TLD in their advanced search :

The fourth option actually gives the possibility to search over a specific site or domain.

Now, if you search, say for .guru, this is what you get :

This looks pretty good : you only can see the sites that are with .guru.
IDN is taken into consideration : 
Now what is surprising is the number.. Really ? 12 million results ? 
I set up my google to have 100 results per page, and if I scroll down to page end, I can see only 6 pages 
6*100, that’s a maximum of 600 pages.. 
If I click on 6, this is what I get : 
So after polishing, it looks like there are 210 entries that are non similar.
even then, some entries seem to be not very relevant.. 
Some results are even stranger : site:.company shows that sort of very unusual results for google : 
But at least, I guess this is a method to measure the actual website activity of a TLD : 
– search google for “site:.TLD”
– scroll and try to go to last page
– you will have a message : “we have omitted some entries very similar to the x already displayed”
– x gives a comparison basis for the actual websites for the TLD.
