If you are taking courses from well-known learning platforms like Coursera or edX, and are receiving certificates for those courses related to the field you would like to work in, definitely add those to your resume. That shows whoever is looking at your resume that you have taken time to learn more and could make you an attractive candidate for the position you're applying for.
Typically on your resume you would include a section for education, so if you take a course and obtain a certificate from that course, add it in there. If you are taking many courses and receiving many certificates, you should add in one or two that are the most closely related to the position you are applying for.
I hope this helps - good luck with your continuous learning!
