Ahrefs review

Ahrefs ranks first because Keywords Explorer answers the question content teams care about most: how much traffic a topic can bring, not just how often one phrase is searched. Each keyword shows search volume, Keyword Difficulty calculated from backlinks to the top-ranking pages, Traffic Potential based on what the No. 1 page earns, and a Parent Topic that tells you whether a broader article would capture the term. The index holds 28.7 billion keywords across 217 locations, and you can generate seed ideas with AI, cluster results by Parent Topic and review SERP history to see how intent shifts. The $29 Starter plan covers keyword and competitor research, and Lite at $129 includes Rank Tracker and Site Audit. The catch is that AI suggestions, keyword clusters and search intents are listed as Standard features at $249 a month, and Lite caps usage at 1,000 credits per user.
