Hi, This might my 1st thread. I find useful info here all the time, so i am posting a question with hope to get better answer. I get a aged domain last month, its registered in 1995, and PR6 with 1000's of quality backlinks. I purchase it in $$$$, and then i start doing all high quality contents on domain. around 100+ high quality posts done with images, i put premium theme. site get traffic, but today i check domain completely deindex from google. i did not put any ad, anything. then i register domain google webmaster tools, and found a msg , google guide line issue. is it against google TOS to re establish aged domain? what is best paractice to do with old aged domains? should i redirect to new domain? i have many other aged domains, those i am in process to build sites, what should i do? Hope to get answers. thanks guys.
