I have a music site -
http://www.scoredchanges.com - which includes a lot of free tutorials in pdf format which can be accessed from the tutorials page.
On the list of pages indexed by Google, some of these pdf files are titled correctly, such as "Arranging", whereas others have goobledegook titles - HHHHHHH etc.
By viewing the files in the HTML option, I see that the goobledegook is actually how the music examples are portrayed, which can be anywhere on the first page, beneath the title.
They were actually written with Personal Composer notation and then I used Adobe Distiller on them to get the pdf.
As no-one searches the internet for things like HHHHHHH, how do I get the real title shown by Google?
