We have launched HTTPS version of site at 6 Oct. After few days (8 Oct.) Google dropped 40% of normal search traffic, and more 20% within next 2 days. SSL certificate was bought from GoDaddy, and server configured correctly without any errors (all internal links/images/scripts also support HTTPS). All URLs are identical like:
http://example.com/this_is_url = https://example.com/this_is_url
Has anyone had a similar situation? Should I write to Google? Or just wait?
