How to tell if PDF content is being indexed?

[zazo]

I've searched extensively for this, but could not find a definitive answer.

We recently updated our website and it contains links to about 30 PDF data sheets. I want to determine if the text from these PDFs is being archived by search engines.

When I do this search http://bit.ly/rRYJPe  (google - site:www.gamma-sci.com and filetype:pdf) I can see that the PDF urls are getting indexed, but does that mean that their content is getting indexed?

I have read in other posts/places that if you can copy text from a PDF and paste it that means Google can index the content.  When I try this with PDFs from our site I cannot copy text, but I was told that these PDFs were all created from Word docs, so they should be indexable, correct?

Since WordPress has you upload PDFs like they are an image could this be causing the problem?

Would it make sense to take the time and extract all of the PDF content to html?

Thanks for any assistance, this has been driving me crazy.

Is the data being displayed in the title and meta description in the SERP content from the PDF?

If so, then yes, they are being indexed/crawled.

Kyle,

Thanks for the quick response.  The data is being displayed in the title and meta description field.  I also did some searches for specific terms with my parameter search from our site and filetype:pdf, which shows that the content is being indexed.  It also shows that the PDF titles and meta descriptions are not optimized, so I have some work there.

Thanks,

Anthony
