A live heatmap of when r/SEO's top 100 posts of the past year were submitted. The brightest cells are the windows when this community engages most.
Analyze a different subredditr/SEO activity tracks closely to working hours across multiple regions, with peaks around 14:00-22:00 UTC. Major Google algorithm announcements drive concentrated activity spikes that completely override normal patterns — posting during a confirmed update can either get massive visibility or get drowned in the noise depending on the angle. Outside of news events, midweek afternoons US time are the most reliable window.
Times above are UTC — the heatmap reflects the trailing 12 months of top posts, so it captures long-term patterns rather than this week's activity. Have questions about how this works? See the main tool page for FAQs.
