OK Idea if you already have a print version. Easily to integrate with wordpress which I believe you mostly use, from reading your previous threads. You can use something like issuu or self hosted flipbook (have not used flip book in years if it still exists??)
Google still has trouble reading PDFs in comparison to straight html. I make a client publish all content separately on his site instead of just having the PDF.
The real question is why ? My client likes the added touch it gives his site but also so his advertisers can quickly read the mag/see their advertisements immediately. Also easier for showing their friends etc
