Ahrefs also earns 4.5/5 and wins on backlink depth - the second-most active crawler and 10+ years of web-scale data that Semrush acknowledges. Ahrefs Lite starts at $129/mo with a 100K credit pool; Semrush SEO starts at $139/mo with 5 sites / 500 keywords. If backlink index depth is the point, Ahrefs is the pick; if you want the widest surface including AI-search tracking and MCP, Semrush is the pick.
