I have quite a bit of excellent content articles at my disposal and we would like to increase the number of pages on our site. I could, theoretically add 100's of pages at a time. Does anyone have a good sense of how much content added to a sight in mass looks bad to Google?

My plan is to add approximately 50 pages a week to our site, which already has 4000 pages of content. This is relevant content, since we are a custom writing service and all topics are covered. Our content is what gives us great organic hits and orders. However, I would like to add more than 50 a week...how many is too many?

Thanks and I appreciate thoughts and feedback!
