The content goes from fairly interesting to weak very quickly as you scroll through the PDF (why PDF?). It starts out with 'A outperformed because...' on the first few examples and gets to 'we have no idea why, just make sure you test' halfway through the document. If it were me I would have stopped at the last proper example and left the rest out. Quality over quantity. You'd think that a marketing agency understood that.

Also: low quality PDF rather than a normal website? Fine, you can send PDFs to people, but it makes for a poor experience. Are there viruses in that PDF?
