I agree with others. You’re profile physically rules out an ENORMOUS chunk of sitters.
A sitter reads the words “home worker” in the title and then it is reinforced and set in stone with the first line of your intro by saying “cat loving home worker required”. So everyone who isn’t a home worker clicks away because they will feel they don’t match what you want.
We sit as a couple, we’re in our 50’s and 60’s, and have a passive income, and there are LOADS and LOADS of sitters like us on here, and there are many other types of sitters too, but you state we don’t suit your requirements by your “home worker required” wording, so we click away.
Home workers are just a smaller proportion of sitters, there are so many different sorts of sitters.
If you are after someone who stays at your home, rather than out and about galavanting every day, then open yourself up to non home workers too and you may be able to gist for what they are like. Most of our sits involve tea rooms, and leisurely local strolls, rather than sight seeing all day every day.
You title could do with improving too. You can check out other pet owners titles for ideas.
That could be because they probably weren’t “home workers” which is what you say you want in your first line of your description, or you didn’t suit their needs in a different way. It’s easier to make sure your own profile is worded correctly and let sitters come to you.
