Around 80% of clients actually decide to search and message carers directly instead of posting on the jobs board, so even if you cannot see any jobs near you, there still may be clients looking at your profile.
Make sure you make your profile as good as it can be. Some of the ways you can improve your profile are:
Update your profile photo to a clear, smiling headshot
Make sure you have uploaded photo evidence of all your qualification certificates
Keep the experience section of your bio up to date, including the skills you have learnt in your recent care jobs
If you have the opportunity to carry out extra carer training, do it! Clients often look for well-qualified carers
