Welcome to the Q&A Forum

Hello Community, Question on negative impact of many virtually identical calendar pages indexed. We have a site that is a b2b software product. There are about 150 product-related pages, and another 1,200 or so short articles on industry related topics. In addition, we recently (~4 months ago) had Google index a large number of calendar pages used for webinar schedules. This boosted the indexed pages number shown in Webmaster tools to about 54,000. Since then, we "no-followed" the links on the calendar pages that allow you to view future months, and added "no-index" meta tags to all future month pages (beyond 6 months out). Our number of pages indexed value seems to be dropping, and is now down to 26,000. When you look at Google's report showing pages appearing in response to search queries, a more normal 890 pages appear. Very few calendar pages show up in this report. So, the question that has been raised is: Does a large number of pages in a search index with very thin content (basically blank calendar months) hurt the overall site? One person at the company said that because Panda/Penguin targeted thin-content sites that these pages would cause the performance of this site to drop as well. Thanks for your feedback. Chris
