Those stats are rubbish..
There are 7,782,346 active publishes in the world.
Jw.org has received an estimated 7,639,900 visits over the last 30 days. The number of visits differs from visitors (or unique visitors). Visits includes multiple visits from the same individual (repeat visits).
That's 254,662 non-unique visitors a day.
So.. if we assume each member visits jw.org just once a month this alone will account for the websites total visitors. The truth is that vast numbers of these members probably visits the site easily 10 times a day every single day (repeat visits) and on multiple devices so these visitor figures plummet drastically.
So.. yes jw.org is being heavily promoted but mostly only among themselves. The world on the other had really does not seem to give a dam.
