You need to first think which job you will do in freelance.
There are hundreds of types of freelance job.
Nobody can do every job.
If you want to do every job then you can not be specialist for any job.
Rather concentrate a type of job like search engine optimization SEO or Social Media Marketing SMM.
Then try for those work only.
Do not bid for other jobs.
If buyers see that you bid for everything they will understand that you are not specialist for any job.
