Ahrefs vs Semrush: which engine do you actually need?

Ahrefs vs Semrush: which engine do you actually need?
Both start around $129/mo, but they're not twins.
Ahrefs
👍 Best backlink index, still — link gap and broken-link reports are faster and cleaner
👍 Cheaper credits if you mostly check competitors' links
👎 Keyword tool feels bolted-on; PPC and social data are thin
Semrush
👍 Wider toolkit — paid ads, PLA, social, content templates in one login
👍 Keyword Magic groups intent better for content briefs
👎 The $129 Pro tier caps you at 5 projects and throttles reports fast; you'll feel the upsell to $249
Verdict: Ahrefs if your bottleneck is link building and competitor backlinks; Semrush if you juggle SEO + paid + content in one seat.
Best for: Ahrefs for link-led SEOs, Semrush for full-funnel marketers who hate tab-switching.
