Fix first
Scores show the order to fix things, not a prediction of search rankings. Basis: general recommendations from Google and Naver public guidelines.
In-depth audit
Speed check
Measures server first response (median of 3 runs), connection, compression, caching, HTTP/2, CDN, and above-the-fold CSS and JS size, scored out of 100, alongside Google PageSpeed Insights mobile score and real-user Core Web Vitals.
| DNS | Connection | TLS | First byte (median) | 3 runs | Total | HTML |

Google PageSpeed Insights (mobile)
Sitemap deep check
Fetches your sitemap like Googlebot, measuring time, size, compression and limits (50,000 URLs, 50MB), then samples URLs by type to check status codes, response speed, noindex and canonical. Takes 20–40 seconds.

Rendering risk check
Fetches the same page as Googlebot and as a regular browser to compare, and checks for body content that only appears after JavaScript runs (streaming, app shells) and where the title and canonical are located.
| Fetched as | Status | First byte | Body | First visible text | Late-arriving share | Links | Canonical location |

This tool does not use Google IPs, so bot-blocking services may respond differently to it as a "fake Googlebot." To see what Google actually saw, use URL Inspection in Search Console: "Test live URL → View crawled page." If it's your site, check My site (Search Console)to see the actual indexing status right away.
