Let's assume I have a website of approximately 40,000 web pages, all of which are currently indexed, and most rank fairly well on Google. I plan on creating new content which will result in a total of almost 200,000 new pages being created (so, 240,000 pages total, six times the original amount).
Can the site be penalized for releasing such a large volume of content in one go? Obviously, if it's poor quality content, I can get penalized for that, but let's assume that it's good content, and pages do not consist of duplicate data.
Is there a benefit to releasing these new pages in batches instead? For example, if the pages are organised by category and sub-category, and I release one category a week, or simply releasing a few thousand pages per week. If so, is there any sort of guideline as to how many should be released, and on what time-scale?
