Ahrefs recalculates Domain Rating continuously as AhrefsBot crawls the web and discovers or drops backlinks in their index. There's no fixed schedule like "every Tuesday" — it's event-driven. The moment Ahrefs finds a new backlink pointing to your domain or detects a lost link, that data feeds into the next DR calculation for your site. In practice, most sites see their DR refresh visibly every 3–7 days if they're actively gaining or losing links, though high-authority domains with constant link activity can shift daily. What actually controls update speed is how often AhrefsBot recrawls the pages linking to you. Popular, frequently updated sites get recrawled faster, so links from major news outlets or high-DR blogs show up quicker than links from static, low-traffic pages. If you just earned a link from a site Ahrefs hasn't crawled in weeks, you won't see the DR bump until their bot revisits that page. DR is a logarithmic score from 0–100 based on the quantity and quality of referring domains, so small sites jump more easily (DR 10 to DR 20 takes fewer links than DR 60 to DR 70). A single strong link might move a DR 15 site up two points overnight, while a DR 65 site needs dozens of solid links to budge one point. At Ottawa SEO, we track DR weekly in our portfolio but don't obsess over day-to-day flux. A site that bounces between DR 42 and DR 44 isn't meaningfully different — we care more about the trend over 60–90 days and whether referring domain count is climbing. DR is useful for quick competitive benchmarking and convincing clients they're moving the right direction, but it's a secondary metric. We optimize for rankings and organic traffic first, and DR follows as a byproduct of earning legitimate links. If your DR hasn't moved in a month despite building links, either those links haven't been crawled yet, they're from domains Ahrefs doesn't value, or you're also losing old links at the same rate you're gaining new ones.
