The best backlink analysis and keyword research tool
Ahrefs is the go-to SEO tool for backlink analysis and keyword research. It has the largest backlink index and the most accurate keyword difficulty scores.
Ahrefs is a strong fit if its core strengths match your workflow, budget, and support needs. Use the quick signals below before opening the full review.
Ahrefs built its reputation on having the largest and most frequently updated backlink index in the SEO industry. That advantage has expanded into a complete SEO platform covering keyword research, rank tracking, site auditing, and competitive analysis — while maintaining the depth of data that SEO professionals use as the gold standard for link analysis.
What separates Ahrefs from its closest competitors is data quality over breadth of features. Its keyword difficulty scores are considered more accurate, its backlink data refreshes faster, and its Site Explorer gives a more reliable picture of what is actually ranking and why. The interface is clean and logical — unusual for a tool with this much data depth.
Ahrefs starts at $129/month (Lite) with no free plan. The Lite plan covers one user, 5 projects, 500 tracked keywords, and 6 months of historical data. Standard ($249/month) adds 20 projects, 1,500 tracked keywords, and 2 years of data. Advanced ($449/month) is designed for teams. Ahrefs Webmaster Tools is genuinely free with limited data access for verified sites.
Ahrefs is the preferred tool for SEO professionals who specialise in link building and competitive research. Content marketers who want to understand what is driving organic traffic for any site, and agencies managing multiple client sites, will get the most value. Experienced SEOs consistently rate it as indispensable.
There is no free plan with meaningful data access. Paid traffic analysis is absent — Semrush is stronger there. Local SEO features are limited compared to dedicated tools. The pricing is a genuine barrier for freelancers and small businesses who do not use it daily.
The best backlink analysis tool available, and a complete SEO platform for professionals who need reliable data. Worth the price for anyone doing link building, competitive research, or content gap analysis at scale.
