i've been testing this for years across hundreds of ad accounts. The short answer? It depends. On platforms like TikTok, the algorithm rewards frequency - but only if your hooks are tight. i've seen clients burn cash posting low-effort content daily and get nowhere.
Here's what actually works: batch create 5-10 strong concepts, test them fast, kill the losers, then scale the winners. Quality still wins - but you need volume to find what quality looks like.
If your extra posts are rushed and not performing, that's a signal. Slow down, analyse drop-off, fix hooks. Consistently beating perfection only works when your baseline is decent. otherwise you're just feeding the algorithm garbage.
For me long term, finding that balance of 3-4 high quality posts per week outperformed 7 mediocre ones. Every time.
I'd say test both for two weeks and compare the data. Don't guess.
That's my two cents
