Ok , a month ago I made 5 blogs under one domain ( 5 subdomains) . I've used caffeinated content and it posts about 5-6 article daily so the contents comes from articlebase and it's not unique. I use to post youtube videos sometimes... My problem is that google refuses to index my posts on each of the blogs. It has indexed only some pages ( 2 -40 ) related to tags but the blog articles are not indexed. I've submited all the sitemaps on google's webmastertool and installed also a wordpress plugin in order to autoping the new posted articles. What else can I do? Does it take so long for the articles to be indexed?
