Help with the art of blink strafing during 1v1s?

Hi, so I've been spamming Tracer recently trying to learn her. When I am in a 1v1 with someone I know AD blink strafing is bad so I just kind of try to be unpredictable, take odd angles or get behind them. If I'm blink range away I might double blink straight at them to get right behind them. This is what I'm doing but I feel kind of like a chicken without a head. Also I use different ranges but maybe there is an ideal range? I have no real purpose and sometimes I lose them myself I'm moving so erratically. Do you guys have any tips or tricks for this? Thank you.
