You vs them.

Paste your site and a competitor's. We audit both on the same 73 documented checks and show who the machines prefer, front by front: overall build, classic SEO, answer boxes, and AI citation readiness. The truth, side by side.

On-page build comparison only, measured live from both sites by the same engine. What it deliberately does not include: backlinks and authority, real rankings, and traffic — those need connected data and are part of the full audit. We never fake a number.
Straight answers

What does this actually compare?

Both sites are crawled live and scored on the same 73 documented checks Brimm uses for every audit: crawlability gates, on-page fundamentals, answer-box eligibility (AEO), and AI citation readiness (GEO). You see the overall build score plus each front, side by side.

Is a higher score a promise of ranking above them?

No, and anyone who promises that is selling folklore. This measures build quality: how ready each site is for search and AI engines. Rankings also depend on authority, content depth, and competition, which is exactly why the full audit lists what it cannot measure instead of faking it.

Why only a few pages per site?

The comparison crawls a sample of each site so it stays fast and polite. The full audit goes deeper, page by page, and names the exact problem on each.
