This seems like a basic question, but its something I've never actually done before. I've already published a page and I'd like to change the url for this page. I want to switch from the main kw in url to and LSI version and gage its impact in the SERPS. There is currently no backlinks made to it as its a fairly new site. I am wondering if changing the url causes any problems in google? Obviously google will have to deindex and reindex the page under the new url and this will take time. Beyond that, is there any other issues to be aware that would make me not want to do this?
