Google announced in August 2014 that website using HTTPS would be used as a ranking signal while showing a result in a search result. This is aim at providing a safer and genuine result to the customers in the Search engine. Further, many websites are aiming at switching over to HTTPS from HTTP to get the favour.
But, the complex technicalities involved in the process can cause your traffic to drop as low as 90%. Buffer has found that after adopting the HTTPS the traffic from Google has plunged to 90%. It has been found that the traffic was constantly decreasing in the website after the adoption. Actually, Google didn’t anticipate that unusual change from Buffer.
The traffic dropped was due to a manual penalty on Buffer and it was imposed at the same time when the site was moved to HTTPS. This has confused the Google team and confirming the reasons for losing the traffic. Thus, John Mueller has commented that Buffer had a penalty on the website even before migrating the website to HTTPS but no confirmation still. It is a worrisome situation which the publishers would think twice before changing their website.
Google hadn’t expected and experienced a rare incident like this before. But, it has been resolved now. We will update the news about it later after getting confirmation.
