It’s something I noticed a fair while back that wordpress retains the first name given to a page even if it is subsequently changed in the page editor. If you check the About and the Contact page you’ll see an seo page title in the browser address bar but the newly given title in the navigation bar which keeps the nav bar tidy.
I’ve been concentrating on seo because I’ve found that finding a taker for a page one site is much easier than finding someone who wants a site.
It would be good to know if the originally selected HOME page in settings/reading keeps it’s name anywhere or if it’s automatically swapped to index with no traces for a Google bot to find. Not a massive issue on this site but if I can’t bag a suitable geo-generic then page title would be good.
