Internal and External Information

Hello Sir, Hope up you are doing well. Can you please answer me in the following question.

Identify by placing a tick in the correct boxes in the table below, whether the information gathered is from an internal or external source.

1) Number of people clicking on the ‘Coming soon’ link on the company’s website
2) How likely one of our customers is to recommend our business to a friend or colleague
3) Share prices of different competitors over time
4)Average household income in Country A in 20X6

Sir, i wanted to know why Statement (2), is an internal source of information.
Because we would be collecting this information from customers who are external to the organisation. So shouldn’t it be an external source of information.
