How do you block particular country in Google-Analytics?

Answer 1

In Google Analytics you can filter out results form a country by creating a new segment.

So you'll need to click +Add Segment.

Then select 'Demographics'. At the bottom of the list, you'll see 'Location'. Click the first dropdown and choose 'Country' then 'does not exactly match' and then pick the country you want to exclude. Now name and save you segment.

To use, click +Add Segment and select if from the list.
