… The industry gold standard and best overall tool for an SEO specialist to find competitor backlink opportunities is Ahrefs , closely rivaled by Semrush . Both platforms feature massive, rapidly updated web-crawling databases and specialized "Link Intersection" or "Backlink Gap" modules that allow you to plug in your domain alongside multiple competitors to instantly identify high-authority sites linking to them but not to you.

2. Semrush - Pick this instead of Ahrefs if you're full-service and also run PPC, content, and social. It's the only major platform that bundles all of that under one login, plus the newer AI Visibility Toolkit for ChatGPT/AI Overviews reporting.

Especially good for seeing competitors’ ads, keywords, and gaps. Ahrefs — better for SEO + content, but still useful for keyword ideas and competitor discovery (less PPC-focused than Semrush). Rule of thumb from real PPC teams: Semrush = better for paid search strategy + ad spying Ahrefs = better for content-driven keyword expansion If you care most about competitor PPC spying (cheap but powerful) SpyFu — very strong for seeing competitor keywords and historical Google Ads performance at a lower price point than Semrush.
Neither ahead

2. Semrush - The alternative to Ahrefs, not a complement. Pick it over Ahrefs if you need breadth: PPC data, local listings management, social, and a genuinely large keyword database.
