  Cody Sharp: The first thing I would do is just absolutely confirm that the https transition was set up correctly. Then I would do a site:www.domain.com search on Google using the http version of your website. Anything come up? If so, Google still has the old version of the website indexed and they will probably work it out over time. Then I would check Google Search Console (the one set up with the new https version and the old one for the http site) and see if there are any weird crawl errors. I`ve done a bunch of these transitions and haven`t noticed too many declines in search traffic but mileage may vary.
