Duplicate Content - Reverse Phone Directory

[sally58]

Hi,

Until a few months ago, my client's site had about 600 pages. He decided to implement what is essentially a reverse phone directory/lookup tool. There are now about 10,000 reverse directory/lookup pages (.html), all with short and duplicate content except for the phone number and the caller name. Needless to say, I'm getting thousands of duplicate content errors.

Are there tricks of the trade to deal with this? In nosing around, I've discovered that the pages are showing up in Google search results (when searching for a specific phone number), usually in the first or second position.

Ideally, each page would have unique content, but that's next to impossible with 10,000 pages. One potential solution I've come up with is incorporating user-generated content into each page (maybe via Disqus?), which over time would make each page unique. I've also thought about suggesting that he move those pages onto a different domain.

I'd appreciate any advice/suggestions, as well as any insights into the long-term repercussions of having so many dupes on the ranking of the 600 solidly unique pages on the site.

Thanks in advance for your help!

If I would be at your place I would have used the idea that you come up with... add user generated content but do check the GUC section you are adding it should not contain an iframe or else there will be no use of it.
