I moved one domain to a new hoster because performance reasons. Same time i reworked some CSS styles. This is now 4 weeks, the site immediatly plumped in searches and did not come back till now, its even getting less traffic.
I redesigned a second site 3 days ago. This site has take a hughe hit yesterday. I will now wait 6 weeks and will not make any changes but will clearly add new content and will fix spelling errors.
