Thanks @wadestriebel. I’ve asked the acquaintance I referred to in my original post for their thoughts and they agree that even this simple change makes a big difference. I’m not sure how long it took you to do it but I think it’s time well spent so thank you for that.
Regarding helping out with the new site, I’m currently working on the new SEO plugin for ClassicPress so I am really struggling for time but I’ll take a look to see if there’s anything I can help with.
Thank you again.
