I recently received a question from one of my friends regarding the use of keywords and descriptions within meta tags on a website to improve ranking of their site. They asked if they could increase the frequency of how often those tags were shown so they could improve the ranking of their site. My response was as follows:
I always forget how to get into maintenance mode on Sharepoint pages to close / remove webparts that are (potentially) causing issues. Sometimes you will even get an error message that provides a link to the maintenance mode pages. There is also some convoluted way of getting into maintenance mode, but I can never remember it.
An easy way to get into maintenance mode is to simply add ?contents=1 to the URL. For example, if your URL was http://sharepointsite.com/pages/default.aspx you would go to http://sharepointsite.com/pages/default.aspx?contents=1
