Let's say I have a Wordpress website for a company. I have a very unique copyscape passed 500 word article with my keyword in there at 2% density, in h1 h2 h3 b i u tags. Bottom line, it's the perfect article to rank my keyword. But the article is random, doesn't have a place in the context of the website, and not grammatically correct (it was spinned.) Another words, I don't want site visitors to actually read it. After it the post gets ranked, I'm going to set it up so that when users click on it, it redirects to the home page. So if I make a post and put this article in, but there's no link to the post on my homepage or anywhere on my site, will it get indexed / ranked if I add it to the sitemap?
