A quick summary of website trackers used by:
jw.org - 0 trackers (not even Google Analytics - wow - they really are in broadcast mode) PageRank 5
mormon.org - 5 trackers - incl. 2 kinds of visitor analytics - they are spending $$ on this as a pro-active campaign with measurable results - PageRank 6
churchofgod.org - similar to jw.org - PageRank 4
adventist.org - Google Analytics only - PageRank 6
catholic.org - 26 trackers incl. many ad networks - these guys are monetizing their audience (huffpost has 19 trackers for comparison) - PageRank 3
scientology.org - 8 trackers (maybe some advertising revenue) PageRank 6
My 0.02 - JW's and CoG etc - true believers who are seriously not interested in who their audience are or how they use the website. In a very traditional brochure-ware approach to the web - no kidding the WTS is a printing company and it shows. Inside the WTS it feels like Web 1.0
Scientology and Mormons - spending $$$ on building an audience, tracking them all the way to membership - the Scientologists for sure know the lifetime $$$ value of an average member and will know to the cent what to spend to convert them
Catholic - different league - content/publishing play with a fully monetized audience for the website alone - no specific goal to convert people - that would be a side benefit of raking millions of dollars per year from the website as a business unit
