15–30 minutes of focused, daily engagement usually beats an hour once a week. What matters most is consistency and being present in the first 30 minutes after you post, when the algorithm is deciding how far to push your content.
Comment well. A handful of specific, thoughtful comments that reference the actual post will get you noticed and reciprocated far more than dozens of “nice!” drops — which platforms can also flag as spam if repeated.
Two windows matter most: 10–15 minutes before you post (to warm up your account) and the first 30–60 minutes after posting (to reply to every comment fast). A second sweep about an hour later keeps the conversation alive.
