Your Chat Widget is Your Digital Front Desk

An embedded chatbot shouldn't look like a generic plugin slapped onto your site. It is an extension of your brand identity. It should match your colors, match your border style, and use clean typography that is readable across mobile and desktop screens.

1. Custom Colors and Contrast

Your primary theme color should match your site's CTA buttons. This makes the chat bubble familiar. Ensure the chat text color has a contrast ratio of at least 4.5:1 against the background to guarantee accessibility guidelines are met.

2. Avatars and Friendly Copy

Give your bot a friendly name (e.g., "Aidni Assistant") and upload a custom avatar. Shoppers are much more likely to interact with a bot that has a professional icon or face over a generic question mark bubble.

3. Position and Floating Bubbles

Place the bubble in the bottom right or bottom left corner. Ensure it is offset by at least 20px from the edges so it doesn't block important elements like footer links or scroll-to-top buttons.
