I have a blog with 10 quality, self written articles that get tiny traffic. I have about 100 not so quality (some spun, some poorly written) articles that I want to ad to my blog. Would it be ok if you could not see these articles from the links on the blog, but they were in the sitemap? This way people would not navigate to them to see how crappy they are, but search engine would send some traffic to it so I can direct them to my offer? Any advice greatly appreciated.
