Thanks to Jan in Wisconsin for sending me an interesting article on search engines and PDFs. A few years ago most search engines did not track PDF documents. Most of them are smarter now. It’s still not the best way to go but there are plenty of times where PDF makes sense and I thought I’d share a few ways to help PDF rank higher:
Write the document as you would a web page for ranking purposes. Use lots of good keyword terms – especially near the top of the document.
Be sure to add a title and meta tags – you can do this in the document properties. Titles are always important – meta tags are less important but still valuable.
Build links into the PDF document. This is good for the PDF and the pages to which it links.
Pay attention to version and size. Search engines don’t like large files – so try to optimize PDF for size. And saving for Acrobat 7 will ensure that more search engines can read it. (Acrobat 8 is out there but still pretty new.)
Don’t bury the document. As with all web documents you don’t want to store it away in numerous folders – leading to very deep links. It’s harder for the search engines to track those pages.
