Can someone please point me to a working link on how to install Wordpress? The link I found from 2010 is no longer available. I know Courtney had one at one time that showed detailed pictures and instructions. I can't believe it's so difficult to find, even through the search bar.
You may not notice a change right away, however, it is possible that the rankings will change over time as a result of the content on your website changing. As Google and other search engines index your site's new content again, they will re-evaluate your ranking.
However, you probably shouldn't see (much) of a hit, as long as the redesign continues to contain relevant content and receive decent traffic.
