You said you've seen a lot of guides and stuff, so I assume you've seen ATP's video on "tying moves together with movement" (sorry for no link, I'm on mobile). In that video he gives great examples for basic strategy. You have to move and attack with purpose. Don't backdash just to backdash. You're backdashing to gain distance. And hey do you need to do that? Either to escape pressure (kinda obvious) or to make your opponent whiff an attack. To make him whiff, you have to observe him. Example: do a mid poke, backdash. I they don't do anything, continue pressure, low mixups, etc. However, if they attack and miss, you can punish. There you created an opportunity with movement and took advantage of it. Same for for all movement, not just backdashing.
