The Verdict
Ahrefs is built for seo professionals and agencies, with a focus on backlink-analysis and keyword-research. FullStory targets product teams and ux designers and leads with session-replay and heatmaps.
FullStory uses custom enterprise pricing, while Ahrefs starts at $129/mo — a tangible advantage for teams with a fixed budget.
FullStory has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Ahrefs requires a paid subscription from day one.
