A while ago I was doing some research on sales letters and opt-in pages. I had to put my project on the back burner for a while but now that I am starting it up again it looks to me like the sites that I was using as reference sites have moved from using an opt-in page, sending the free gift (ethical bribe) and then redirecting to the sales letter page, to not using an opt-in page and just having the sales letter... It this a trend? or did I just happen to use reference sites that have chosen to 'go a different way' and do not represent the 'norm'? Appreciate any feedback on where people see the use/ need of opt-in pages today and going forward.
Thanks in advance,
