Enter a domain to diagnose SEO scores for all major pages at once

Last updated: 2026-06-16

What is site-wide SEO diagnosis?

Site-wide SEO diagnosis fetches every page from your sitemap.xml with a single domain input and scores each page at once. Instead of checking pages one by one, you see which pages are weakest across the whole site and fix them lowest-score-first. Single-page checks are free; site-wide bulk diagnosis is available on the Entry plan and above.

What Site-wide Diagnosis Reveals

Bulk SEO scores for all pages

Automatically fetches pages from sitemap.xml and scores each page out of 100.

Problem pages shown by priority

Lowest-scoring pages are listed first, so you can start with the highest-impact fixes.

One-click to detailed diagnosis

Click any page in the list to see 45+ detailed check items and auto-generated improvement code.

Overall SEO health at a glance

Average score and score distribution give you a bird's-eye view of your site's SEO status.

Why Site-wide SEO Diagnosis Matters

Checking individual pages alone can miss site-wide issues. If certain pages have low scores, they may be dragging down your entire site's evaluation. Site-wide diagnosis lets you instantly see which pages have problems and prioritize fixes.

Google evaluates overall site quality. Serious SEO issues on even a few pages can affect your entire site's search performance. Regular site-wide diagnosis and fixing low-scoring pages helps improve your site's overall search rankings.

How to run a site-wide SEO diagnosis (4 steps)

Site-wide SEO diagnosis scores your whole site from a single domain input instead of checking pages one by one. The following four steps let you fix the weakest pages efficiently.

  1. 1

    Enter a domain to load sitemap.xml

    Enter the domain you want to audit, and the tool automatically fetches target pages from sitemap.xml. There's no need to paste URLs one by one.

  2. 2

    Bulk-score every page

    Each fetched page is diagnosed across 45+ items and scored out of 100, all at once.

  3. 3

    Identify problem pages, lowest score first

    Results are sorted lowest-score-first, so you can see at a glance where weaknesses cluster across the site and start with the highest-impact pages.

  4. 4

    Drill into each page for specific fixes

    Click any page to see its 45-item detailed diagnosis and improvement code — down to exactly what to fix and how.

Single-page check vs. site-wide diagnosis

Single-page checks and site-wide bulk diagnosis serve different purposes. Use each according to the situation.

What to know before you rely on the diagnosis

An honest note: Site-wide diagnosis only covers pages listed in your sitemap.xml. If the sitemap is missing or outdated, the audited scope may differ from your actual site. Scores rate technical and structural SEO factors — they don't guarantee content quality or alignment with search intent. Alongside fixing low-scoring pages, a human should judge whether each page actually answers the reader's needs.
