topic : falls/fall prevention/seniors reddit: not too many hits, 1 4 hrs ago. everything else is spaced months out amazon: a few books, but again low hits under 100 comments/feedback post youtube: best results so far with a good variety of videos. 20-40k hits but videos are dated 3-4 yrs ago. and I feel like 20-40k is still a low # generally speaking how big youtube is. Kind of feeling I may need to explore another niche with low/outdated hits.
