Should I practice building automations on Upwork before taking real jobs, or just jump straight into applying?
Just jump straight into applying to Upwork jobs. If you build the automation ahead of time and present it to the client, your marginal cost is only a dollar or two per application, and you control whether they see the proposal by bidding high. This gives you a higher reply rate, and Upwork no longer refunds connects, but you also aren’t charged if they don’t accept.
