Analyst take: what the data says about SEMrush vs Ahrefs

SEMrush has the clearer adoption lead as of September 2026, ranking #35 overall compared with Ahrefs at #47. Their adoption ranks have moved at the same pace over the past year. By spend, SEMrush ranks higher (#29 versus #33), which shows where more of the measured software budget currently sits. The switching signal adds useful context: after leaving SEMrush, some companies adopted Figma or Adobe. The practical takeaway is to separate market position from product fit: the rankings show which tool is more established and where buying momentum is moving, but they do not measure features, price, or quality. Use those signals to build a shortlist, then decide against your own workflows and requirements.
