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.
No signup form:
Too bad I don’t have all the comparative conversion numbers for these, I would be interested, and you might be, too.
