How do i find low competition keywords with high traffic properly?

High traffic plus low competition barely exists for broad terms - someone already owns those. What you actually find is a lot of mid-volume long tail where page one is weak. So don't trust the difficulty score on its own. Pull a list, then look at the real results. Forum threads, reddit, thin listicles, old posts, sites smaller than yours ranking = gettable. Ten big brands = move on. Ten easy keywords at a few hundred searches each add up to more than one big one you'll never crack.
