Employers can post jobs directly on to indeed. However, I've found the quality of applicants from there to be very low. I get about 10 totally unqualified people for every one that I might consider. Better to apply directly to the company if you want to be taken seriously.
Well there is your reason, ssd. You need to think hard about what type of job you want, what skills, qualifications and experience you need to get that job. Just being the right amount of hours is not a good enough reason to want a job. I suspect that may come across in your applications.
Are you tailoring your applications to each job? Detailing how your skills and experience match the job requirements? Is your CV detailed enough? I find the standard Indeed ones are very basic. Oh, and I'd include your contact details. I've found so many of the people I contact via their Indeed e mail accounts never actually receive my e mail.
