Autogenerated pages

[metadata]

My main product is database conversion software. As it supports tons of databases, it's fairly easy to generate thousands of landing pages simply by variating source/target database names, connection information etc. In fact, I autogenerated almost 25k pages that way.

As I didn't want to jeopardize my main site, I placed all that content to a new microsite (www.fullconvert.com) which had no history and no inbound links. Results were nice - site is live two months and in second month already had 1300 visitors.

Now, my question is - should I create the same thing on my (old and rather authoritative) main site www.spectralcore.com? I could use a different template to avoid duplicate content. Of course, my main concern is being penalized by Google.

In my opinion, this autogenerated content is fine because it provides (tons of) laser-focused landing pages, so visitors will instantly recognize they found what they're looking for. But Google might disagree!

What do you think? Is there a danger in trying to leverage authority of my main site in adding 20k+ autogenerated pages with inbound no links to them?

Hi Anthony,

thanks for your answer. Sorry, but this is a duplicate question. After I posted it first time, SEOmoz still reported I didn't post any questions, ever. So I went ahead and typed it again. Your answer is valuable, so I will mark it as a good answer.

I think if you added pages over a period of time and not all at once you should pretty much fly under the radar, providing the change in content per page is significant.

Is it at all possible to make a third site for trial purposes, then you would have three sites that could potentially rank well. Now if you can land all three on first page google you wold be doing very well.
