PDF files will soon include dynamically-generate adverts, following a deal between Adobe and Yahoo.
Until now, publishers have been able to embed only static ads on PDF files, but Yahoo and Adobe are developing a system to make those documents display contextually relevant ads delivered on the fly from Yahoo's inventory at any given time.
Adobe and Yahoo are expected to announce the initiative, called Ads for Adobe PDF Powered by Yahoo, today and launch a limited beta programme that they hope to open up more broadly later.
The inclusion of pay-per-click text ads on PDF files will give publishers another revenue-generating option for the content they have in this popular Adobe document format, said Kurt Garbe, entrepreneur in residence for advertising at Adobe.
As the practice of charging for content continues to dwindle industry-wide, publishers need to monetise their free content with advertising, which has been a challenge for PDF files, Garbe said. "This is a straightforward service to let publishers insert dynamic ads into PDF content," he said.
The benefit for advertisers: they get a new channel for their ads. Readers will benefit when publishers offer for free documents that they previously charged a fee for, or that they simply didn't make available online.
At this beta stage, the programme will provide ads from the Yahoo network exclusively. Garbe declined to comment on whether the programme will later be open to other ad providers like Google.
It's not a surprise that Adobe would want to be vague about letting other ad providers into the program, since it shouldn't close the door on that possibility, said Matt Swain, a senior analyst at InfoTrends.
However, for now, the partnership is a very good match, and even if Adobe partners with other ad providers later, Yahoo will have an advantage, Swain said. "PDFs are a widely used document format, so this is a big untapped area for advertising," he said.
This is how it will work: publishers will upload to an Adobe/Yahoo portal the PDF files on which they want to display dynamic ads. The vendors will send the files back after reconditioning them to display dynamically generated Yahoo text ads whenever a website visitor calls them up.
Adobe and Yahoo envision simplifying the process in the future, Garbe said. For example, APIs are planned to automate the uploading of PDF files to the Adobe/Yahoo portal, and it's likely that Adobe will build in functions in the PDF creation software so that publishers can generate documents with the advertising capabilities.
