Recently I upgraded a site to use an SSL certificate and noticed strange behaviour with Google Webmaster Tools.Before starting the changes Google WMT Sitemap for http://www.example.com was showing as 920 pages submitted and 774 indexed.After getting the site fully working with the SSL certificate, removing the sitemap for http://www.example.com/ and submitting a new sitemap for https://www.example.com/, Google WMT Sitemap for https://www.example.com shows as 920 pages submitted and 799 indexed -- however, Google WMT Sitemap for http://www.example.com has changed to now show as 1840 pages submitted and 1573 indexed, so clearly this has been influenced by the recent submission of the https://www sitemap.I would be grateful for your thoughts on why this might be.The traffic (impressions and clicks per day) has remained roughly the same though has gradually moved from the http://www.example.com profile to the https://www.example.com profile as expected.
Sitemap submitted to HTTPS profile also influenced HTTP profile in Google Webmaster Tools
