I work with a suite of designers who use InDesign CC to create documents they export to PDF for uploading to our website. The designers enter keywords in the file information and separate them with commas. However, when they export the document to PDF all of the commas get changed to semicolons, which I understand is bad for Search Engine Optimization.
So two questions:
1.) Is there a setting somewhere we are missing to make sure our commas are retained?
2.) Does it even matter if keywords are separated by a semicolon vs. comma. Will the keywords still be picked up by search engines?
It is not possible to retain the commas. The same thing happens when keywords are entered in other Adobe programs like Photoshop and Illustrator. It doesn't matter if keywords are separated by semicolon or comma.
Neither the comma's nor the semicolons are actually present in the PDF. They are stored separately in a kind of list. It's just the way the information is shown in Acrobat Reader.
