(Hi Pearl. Off-topic here. For your site speed, I recommend you remove the sharing plugin you have from Shareaholic and use this one instead. https://wordpress.org/plugins/scriptless-social-sharing/. Shareaholic is known to slow down your site and also advertise without your consent unless you have opted into their advert services.)
