hi

i build a site with a lot of articles in pdf.

the articles are full of very important and informative information.
the author insists on using pdf.

how do i tell google about the pdf's and about their content?

someone advised me to put the pdf in an iframe within an html page, and add a div of 1 pixel with the text (or at least extract of the page? or even only keywords?)
this means there will be links to html pages that include most of the data, and the surfer will see pdf.

can it work?

does google allow it?

is there a better or simpler way?

thanks
