I’ll admit that I think that Tony Shepherd is a great writer, who I consider to be a mentor.
I licensed from him a series of 10 short reports that he uses as lead magnets in his business.
These do not come with any PLR rights or anything, and the links inside the reports aren’t active, but I think some of the information in some (or all) of them are great, certainly worthy of the few minutes it will take to read each.
Since Tony has been successful in building a responsive list, I would consider these to be a good example of what kind of content it takes to have a valuable lead magnet that gets people to start following you.
