Hi all, Ok, so I am reading that adding google +1 to a sidebar which shows on all pages will reveal a page that is disallowed in robots.txt See this from google website: Note: +1 is a public action, so don't add the button to any page you don't want visible on the web. When you add the +1 button to a page, Google assumes that you want that page to be publicly available and visible in Google Search results. As a result, we may fetch and show that page even if it is disallowed in robots.txt or includes a meta noindex tag. So, if a page is disallowed or no longer exists then google will show it as a negative and affect SERP - correct? Is this the case with adding facebook and twitter etc? Ever since they have been on my sidebar my SERP has dropped and been inconsistent at best. Falling from middle of page 1 on google to bottom of page 1 on google to top and middle of page 2 on google. Any thoughts on this? Thanks in advance, y
