I already made a post on official wordpress forum,but hava no replay to my question. Also made a search in the forum here and in Google as well but couldn't find solution for my problem. I'm using CMS theme for my website foxcleaners.co.uk with static homepage. The problem is that i have to choose a post which the theme will use as a homepage.OK,i made a post for the homepage and set as noindex,nofollow,but Google has indexed this post!!Also can anyone tell me how Google found this post?There is no links to it.I don't have categories menu on sidebar..?The best solution will be if someone can tell me how to set a unique homepage (without to choose post or page).I love WP but this is huge problem for people like me who wants to use it as CMS system.
Your question is quite unclear, that's probably why you are getting inconsistent answers.
If you want Google not to follow you (or any search website), you could use, as recommend by WPMU-DEV Ari, "Search Engine Visibility" which can be found in the Settings -> Reading menu. However remember, search engines are not forced to listen and/or obey your request.
From the comments I am getting that you believe www.site.com and www.site.com/home are both indexes and displayed on search engines? And your trying to avoid this?
Also if it would occur, users will actually never realize it due to the redirect. (Just try going to www.site.com/home and you will see it will automatically redirect you to www.site.com.)
If this is not what your looking for, you could also create your own static page by creating a custom page template and setting this as your static page. Or create a custom page and redirect your domain to this page, instead of WordPress's Index.
In regards to the question: "how Google found this post?". I am not finding any
