google, links, mixed caps, document converted to html,code

Hi.

I am curious about something. Sometimes if I do a site search in Google, it
will bring up all those links to the pages within that site. (site:domain.com)
If there are .pdf document links, the link will show up in mixed caps.

Ex. "100% All cOtOn T-sHiRts"

I noticed if I clicked "View as HTML" on the search page from Google near the
..pdf link, within that source code I see:
<br>Google automatically generates html versions of documents as we
crawl the web.</div></div><div style="position:relative">

After that I see the title:
<title>100% All cOtOn T-sHiRts</title>

Just curious why Google did it that way if anyone knows? Trying to figure this
out for somebody.

Is there a way you can change it in DW?

Would you have to apply the title, description & keywords to the .pdf doc?

Thanks.
