I'm in the process of launching an info site. The big draw is PDF documents which are mostly made of images.
Usually I just post pages as I go, but I've hired a team to write descriptions of each PDF. I post the descriptions on the HTML 4-6 weeks after I make it live.
Currently the HTML files have listings of PDF files with the actual title, preview image, and a working link to the complete PDF. I just have the word "Description" posted next to it.
Is there any long term SEO harm if I leave it like that? Should I noindex those pages now or not worry about it?
