Yup, you can get creative, depending on your experience, strengths and preferences. Like some sitters enjoy rural sits and/or don’t mind mowing or gardening. If so, you could include photos of you guys mowing or gardening, for instance. Or maybe you with plenty of homegrown vegetables or flowers, to show how you’re a green thumb. Or say you have your own pool or hot tub and share a photo of your taking care of them. And so on.
Or maybe you want to sit in a particular location and you have photos to share that show your connection to the place. Or you have experience with certain breeds of pets. And so on.
The key thing is, hosts will typically prioritize choosing sitters who would take the best care of their pets and home. That would be logical and apply to the greatest number of potential hosts.
