The head and Meta Tags: charset, viewport, title, description, Open Graph, theme-color and link rels
A good head starts with meta charset, carries a single viewport that does not disable zoom, a page-specific title and one description, and puts Open Graph tags in the HTML from the server. In this post we measure that a page without a charset breaks Turkish characters, that a phone lays out a page without viewport at 980 pixels, that bots miss Open Graph added with JavaScript, color-scheme, and repeated meta tags in a Razor layout, with the Nu Html Checker and axe.
