Hi Eva, Do you have Webmaster Tools set up for the domain? If you do, you will usually be sent a message in your Webmaster Tools account if you have a penalty attached to your site for whatever reason. The penalty messages are not particularly descriptive, but they will tell you whether this is a penalty or is just the site no longer being strong enough to rank well in comparison to its competitors. I see the subdomain properly indexed and being returned for its brand name - do you see this too? http://i.imgur.com/A0P6Hee.png That said, searching for terms like [tutorpace math] do not return the subdomain. Is there a reason why math and English are on subdomains but science, economics, etc. are on subfolders / pages? Then, within science, we go back to subdomains for chemistry, biology etc.? It's generally advisable to keep content on the same subdomain, like "www", so you'd have www.tutorpace.com/science/biology, www.tutorpace.com/math/algebra/, etc. Have you done any deliberate link building to the site or employed an SEO company to do so? Real penalties are usually because of bad link building activity or very poor on-page optimisation (although a lot of different factors make up "bad" link building and "bad" on-page SEO). You do seem to have some internal pages that are indexed but contain no content: http://i.imgur.com/zy7cox7.png --> http://i.imgur.com/v7Y6C1p.png Do you know where these blank pages might have come from? They should return **404 Not Found **or 410 Gone server responses so that Google removes them from its index quickly, rather than continuing to return 200 OK responses (as they are right now, as is shown by the plugin in the screenshot). Another issue is that the content on the Math page is duplicated elsewhere, including on the very strong Facebook domain, via the company's official Facebook page. You need to provide unique content for the Facebook page than what is published on the website: http://i.imgur.com/9hAKoc0.png Ensure that the content on the pages is unique - you can't stop scrapers from picking up your content and publishing it elsewhere, but you can ensure that you don't deliberately publish it in more than one location. I hope these points help. Thanks, Jane

Hi Eva, Like Google, it can take time for your site to be accepted into the index for the first time. There are also a lot of other reasons why this could be happening, but rather than try to go through them all here, have a read of this exact question over at Bing http://www.bing.com/webmaster/help/why-is-my-site-not-in-the-index-2141dfab Hopefully that will be of use. -Andy
