Alert bars – also known as sticky bars, floating bars, notification bars, or hello bars – are a flexible, easy-to-use tool for keeping audiences about your COVID-19 response strategy.

Alert bars provide a highly visible zone at the top of your website that can be used to promote breaking news, updates, instructions, and other key information to your customers during a crisis situation.

While ideal for communicating your COVID-19 news and updates, alert bars can also be used for a variety of non-emergency applications, including:

  • Changes to hours of operation or contact info
  • Service changes for transportation authorities
  • Limited-time sales promotions or offers
  • Scheduled website maintenance

Regardless of your message, an alert bar is incredibly effective because it grabs a visitor's attention without interfering with the rest of your website content.
