Your website and e-news
Once you have the jpeg image of your Star award, why not add this to your homepage so visitors see it as soon as they land on your website? You could also mention it within your "about us" section. And, if you send out an enewsletter, you could add it to the banner or footer of the email. Something else to consider is adding it to your auto signature on all emails being sent by your business.
Share on social media
Share your award with your social media followers and do it regularly so you keep it front of mind. It could be something as simple as:
"Take some time for yourself and visit our 4 Star accommodation where you’ll find quality guaranteed."
"Bring your family along to our 5 Star attraction. You can expect exceptional customer service and high-quality facilities – the perfect day out."
And why not add your award to the "about section" on your Facebook page, your Instagram profile, or your Twitter or Threads bio?
