Seo Platform

Ahrefs is an all-in-one SEO and digital marketing platform built around one of the largest backlink and keyword databases on the web, powered by its own web crawler (AhrefsBot). Day-to-day users are SEO professionals, content marketers, and agency practitioners who rely on it for backlink analysis, keyword research, rank tracking, technical site auditing, competitor intelligence, and increasingly AI visibility monitoring via Brand Radar. It is a premium-priced, bootstrapped product with no free trial; the credit/seat-based pricing model and overage charges require careful plan management for teams.

Semrush is a modular digital marketing intelligence platform built around a proprietary database of 20+ billion keywords, 43 trillion backlinks, and—since 2025—261+ million tracked LLM prompts. Practitioners use it daily for keyword research, SERP rank tracking, technical site audits, competitive backlink analysis, and AI visibility monitoring across ChatGPT, Perplexity, and Google AI Overviews. The platform spans SEO, content, social, PPC, local, and PR via independently purchasable toolkits or the all-in-one Semrush One bundle.
