Hi there, If you choose to block Google from caching your page, will it effect your rankings? Since Google is still can crawle the page. Example code: <META NAME="ROBOTS" CONTENT="NOARCHIVE">
Google told me this: Prevent or remove cached pages Google automatically takes a "snapshot" of each page it crawls and archives it. This "cached" version allows a webpage to be retrieved for your end users if the original page is ever unavailable (due to temporary failure of the page's web server). The cached page appears to users exactly as it looked when Google last crawled it, and we display a message at the top of the page to indicate that it's a cached version. Users can access the cached version by choosing the "Cached" link on the search results page. To prevent all search engines from showing a "Cached" link for your site, place this tag in the <HEAD> section of your page: <META NAME="ROBOTS" CONTENT="NOARCHIVE"> To allow other search engines to show a "Cached" link, preventing only Google from displaying one, use the following tag: <META NAME="GOOGLEBOT" CONTENT="NOARCHIVE"> Note: This tag only removes the "Cached" link for the page. (((( Google will continue to index the page and display a snippet. ))))
If a url is not cached how is it possible to found it in SERP???? If you are talking to block google bot to index some of ur pages & asking if it is hurt ur ranking on other pages then the answer is NO. It never hurt you.
