The Witnesses are stuck in the door-to-door-salesman routines of a pre-electronic world, with no electronic outreach except watchtower.org, which no one will ever find unless he goes to look for it.
I think JW's have solved this problem since september 2012 with JW.ORG and their publicity campaigns, ipads, showing short movies to householders and so on.
According to Alexa.com JW.ORG is ranked no2 out of more than 80,000 religious/spiritual/atheist websites
