Gotta love the keyword search function on G**gle...here is the top 5 out of 100 most searched terms using the keyword "Jehovah's Witnesses". These numbers are based on a per month average.
Jehovah's Witnesses Global Search 450,000 U.S. Search 246,000
jehovahs witness Global Search 368,000 U.S. Search 240,000
what is a jehovah witness Global Search 550,000 U.S. Search 301,000
jehovah witness religion Global Search 22,200 U.S. Search 18,100
is jehovah witness a cult Global Search 6,600 U.S. Search 4,400
After I recorded this search criteria, I went ahead and plugged them into the google search engine to see what site shows up first in their rankings.
Jehovah's Witnesses = www.watchtower.org
jehovahs witness = www.watchtower.org
what is a jehovah witness = www.watchtower.org
jehovah witness religion = http://en.wikipedia.org/wiki/Jehovah's_Witnesses
is jehovah witness a cult = http://carm.org/is-the-jehovahs-witness-religion-christian
So, conclusion is this. If anyone decides to start a blog or website that is anti-witness, these keywords (although the most searched), also have low competition for your SEO.
As a sidepoint, I typed in the key website "www.jw.org" and it is not even listed in the top 100. I typed in the key website www.watchtower.org (which they are supposedly taking down) and it has a monthly hit status of over 2,000,000 global and 1,000,000 U.S....most of which are directed towards .pdf and audio downloads. So, if anyone decides to build an anti-witness website called www.x-jw.org (which is still an available domain) using some of the top 5 key words listed above, you may have something. And when I say something, I mean a first page listing in direct competition with the soon to be touted www.jw.org website and probably right before wikipedia.
www.jw.org will always have first place because they have deeper pockets, but atleast yours would show up fairly fast if you market it well enough and get enough visitors. Which you can get just by networking with people on this forum and/or posting your site in your signature. And don't forget to reference your site on wikipedia if you add a bit to their explanations (see wikipedia website listed above).
I would love to do this project myself, but i'm too busy hugging my smurf doll, having sex, and watching R rated movies. So have at it people. If you need further help on this project, feel free to consult the following site:
