My friend came to me with a concern: One of his adsense accounts was recently banned. He had one site with adsense ads on it. He is not sure why he was banned, but he has some other sites on the same godaddy hosting account and he is trying to get them indexed. these sites are legitimate non-adsense sites for his clients. at least two sites were created in the month prior to him getting banned, and these sites have been indexed by bing and yahoo, but google has not indexed them. I told him about the "sandbox" but he nor i have ever experienced google taking so long(or refusing) to index a site. Does google look at other sites on shared hosting accounts when deciding to ad them to SERPs, or is this just a coincidence? Is it possible that these site on the hosting account will never be indexed? note: other sites that were created before his adsense account went online are still being indexed and performing quite well with no change. Thank you in advance for any knowledge or advice.
