The Answer is 3

I just searched for ‘fx trading’ on Google (http://www.google.com/search?hl=en&q=fx+trading)

I was interested in how many of the top ten advertisers on this search term pulled a sign up form directly up into the landing page above the fold rather than providing a more informational landing page with links (numerous?) to the sign up form.
The answer is 3.

Signup form:
Forex.com
Odlsecurities.com
Saxobank.com

No signup form:
Cmsfx.com
Fxcm.com
Gcitrading.com
Ac-markets.com
Easy-forex.com
Fxsolutions.com
Choiceodds.com

Too bad I don’t have all the comparative conversion numbers for these, I would be interested, and you might be, too.
