Reads well, has enough linking words and phrases, flows well, is grammatically and punctually sound, goes in-depth into the topic without too much filler content, is well-optimized, has well-thought-out H2s and H3s, has only relevant interlinks and outlinks. i can go on forever. my articles rank first or second page 10 minutes after i've posted them (after submitting a manual request) and I do nothing but content and on-page optimization
