How prioritization works

Three signals: estimated monthly search volume from Ahrefs/Semrush data, competition level (how strong are the top page-1 results), and difficulty to build well in a static-HTML+JS setup. Priority 1 means high volume + low competition + buildable in a day — those ship first. Priority 2 needs more engineering or has more competition. Priority 3 is "nice to have if there's demand."
