I loved the guide. While quite long, it's fast to read and you can dive deep into chapters that interest you most at a particular moment. Looking forward to more guides from this team!
The "get it sent to you" form field, but then scroll down to read the first chapter is a bit confusing. Perhaps just get people to read the first chapter with you CTA above the fold saying, "Read the first chapter now" and then have the form field for an email at the very bottom.
And it'd be nice to tell me when (and what frequency the chapters) get sent to me. So I know what's coming.
The headline says: "PQLs" >> I wouldn't have known what that meant necessarily (and I'm a saas marketer). I would avoid acronyms in your main headline.
