sure priyam..be it seo or any high paying skill..the process is same..if you don’t already have domain knowledge..do it for 90 days…make a list of all resources available to learn that skill…go through them all for 90 days..share what you learned everyday on your twitter or LinkedIn..because that’s where most clients hang out..this will be your proof of work when you are a beginner…reach out to people in your niche and offer to work for free for a couple of projects..do it for 2–3 projects..not more than that…get testimonials from them..this will be your portfolio..now you can leverage this to get more clients on social media or on upwork..freelancers today have a better chance of getting clients if they actively reach out potential customers through cold email than wait for work on upwork..this is the gist..but i will write a more detailed article on this soon.
