A sticky website is one that keeps viewers engaged by providing interesting and useful content, media, and features that encourage users to stay on the site and return frequently. They aim to maintain a low bounce rate by grabbing users' attention with videos, pictures, games and customization options. Early websites provided basic information, but viewers now expect more graphics and interactivity to remain interested, leading sites to incorporate eye-catching elements to better retain users. Key factors for stickiness include abundant yet organized content, engaging media, internal and external links, advertisements, and customization.
