Add a favicon

A favicon — the small icon appearing in browser tabs, bookmarks, and various other browser interface elements — provides genuine, if subtle, brand recognition and professional polish that its absence noticeably undermines, particularly for visitors who keep multiple tabs open and rely partly on these visual icons for quick tab identification.

Beyond the direct browser tab presentation, favicons appear across numerous other contexts including bookmark lists, browser history, and increasingly in search result presentations on some platforms and devices — comprehensive favicon implementation ensures consistent, professional brand presentation across this full range of contexts rather than leaving some to browser default, generic icon presentation.

Modern favicon implementation genuinely benefits from providing multiple icon sizes and formats to properly support the range of contexts and device types where this icon might display — a single, low-resolution icon may present acceptably in a browser tab but poorly in other contexts requiring higher resolution, like certain mobile home screen bookmark presentations.

While representing a relatively minor individual element compared to some other technical checks discussed throughout this broader work, a missing favicon creates a genuinely noticeable, unprofessional impression precisely because its absence is immediately visible across virtually every interaction a visitor has with your site through their browser interface.
