Ahrefs is the best SEO tool for backlink research and competitive analysis. Its backlink database is the largest and most frequently updated of any tool we tested — crawling 8 billion pages per day. The Site Explorer, Keywords Explorer, and Content Explorer are all best-in-class. The main limitation is price: Ahrefs Lite starts at $129/month and the team plan is $449/month. For freelancers and small agencies, the price is painful but the data quality justifies it for serious SEO work.
Screaming Frog SEO Spider is the industry standard for technical SEO audits. It crawls your website the way Google does, identifying every broken link, duplicate title, missing meta description, redirect chain, canonical error, and JavaScript rendering issue. The free version crawls up to 500 URLs — enough for most small sites. The paid version at £259/year ($330) is the best value technical SEO tool available: nothing cloud-based comes close to its depth and speed for the price.
