Ahrefs built its free checker on top of an asset most competitors do not have, its own crawl index, which gives it a real edge on backlink and domain authority context that a fresh, isolated scan cannot replicate.
Where Ahrefs genuinely wins
Because Ahrefs already crawls a large share of the web for its core SEO product, its checker can pull in domain authority and backlink signals alongside the technical AI readiness checks. That combination, technical access plus authority context in one free report, is not something a single page fetch based tool like ours can match.
Where ours fits differently
Ours does not carry a crawl index or backlink data, it checks the technical and content signals that determine whether an AI crawler can read and extract the page correctly, then routes directly into a managed service that fixes what it finds. Ahrefs' checker is a strong first look, especially for anyone who wants domain authority context in the same report. Ours is built for someone ready to move straight from diagnosis to a fix.
A reasonable approach: run both. Ahrefs for the authority picture, ours for the direct path to getting the technical gaps closed.
