As a habit, I download any kind of free ebook that sounds like it might be interesting. Signing up for a list is easy enough, and I can always ignore it or unsubscribe.
That said, in the last week I've gotten not one but two reports that were four pages long, and that includes the over. I'm dubious that any report of such a short length will have a nugget of info that I can really use, but I think it's possible. If I wanted to install a plug in, that might be the right length.
But these had no real content. They were well written from a technical standpoint, and I suspect whoever wrote them could write a pretty good report. But there was seriously no information in these.
The overall effect being that in spite of them being free, I somehow feel like I should get my money back. It's pretty much guaranteed that I won't buy anything from them or the list owner who sent me their link.
Seriously, newbies - a report like these two is worse than nothing. You'd have been better off just asking me to sign up for your list.
