Question 1

How does the Reddit Post Timing Optimizer work?

Accepted Answer

It fetches the top posts from the subreddit you enter (up to 200 posts from the past month and year), then analyzes when those posts were created. It groups them by day of week and hour, computes average engagement (upvotes + comments), and normalizes the results into a visual heatmap so you can see at a glance when content performs best.

Question 2

What data is this based on?

Accepted Answer

The tool analyzes Reddit's top posts for the subreddit using Reddit's official API. It looks at up to 200 posts spread across the past month and year to give you a representative sample of high-performing content and when it was published.

Question 3

Are the times shown in UTC or my local time?

Accepted Answer

All times are shown in UTC (Coordinated Universal Time), which is how Reddit stores timestamps internally. Convert to your local timezone — for example, if you're in New York (UTC-5), a 2pm UTC slot means 9am EST.

Question 4

How often should I re-check optimal posting times?

Accepted Answer

Posting patterns on Reddit tend to shift gradually. Re-checking every 4–8 weeks is usually sufficient. If a subreddit undergoes rapid growth or a change in its audience, patterns may shift faster.

Question 5

Can RedditGrow automatically post at the best times?

Accepted Answer

Yes. RedditGrow's posting queue automatically schedules your approved responses and posts to go live during optimal windows. The same heatmap analysis powers the in-app scheduler so you never have to guess timing again.
