My Site Looked Professional.Then I Checked the Browser Tab.
I was building a client site, felt good about the design, launched it live. Three days later I'm looking at my own browser with five tabs open and theirs has no icon, just a generic blank square next to the URL.
Small thing, but it's the first thing someone sees when your site sits open beside Gmail, Slack, and their email.
A favicon is that tiny 16x16 or 32x32 image in the browser tab, bookmarks, and address bar. Most people don't consciously notice it, but they notice when it's missing.
Web.dev's breakdown covers implementation, and it takes maybe ten minutes: the image file plus one line in your HTML head.
What I realized is that a favicon signals completion. It tells someone your site isn't a draft or a template, the same reason you put a logo on a business card.
Our web design work includes it as standard now, because small polish compounds. A missing favicon won't sink you, but on a crowded tab bar it quietly reads as unfinished, and unfinished erodes the trust you're trying to build.
Open your site in a browser tab right now. If there's a blank square instead of your logo next to the URL, you're missing a favicon. Add a 32x32 image and one line in your HTML head. Ten minutes, and your site stops looking unfinished on a crowded tab bar.
