There is proof of a large boost recently for sites running fully on HTTPS (secure) from Google organic search traffic.
In the past, there was only a slight increase; the reward seems quite real now. The proof was from a company that runs thousands of websites in a competitive category. Combine that with Chrome’s warnings when filling out forms on unsecure pages and there is a clear path for making websites secure.
We are encouraging clients to secure their website and purchase an SSL certificate.
Once it’s ready, we can make sure that all versions of your domain redirect to HTTPS.
