Foundation audit for both traditional search and AI citation. Most critical GEO gates: server-side rendering (AI crawlers do not execute JavaScript) and AI crawler access (sites often inadvertently block AI bots in robots.txt). 8 categories, 100 points.
Sub-check details, fix lists, framework-specific SSR solutions, and the IndexNow protocol explainer are in checks.md alongside this file. Reference it as needed.
Sub-checks (detail in checks.md §1):

Critical: As of July 2024, Google crawls ALL sites exclusively with mobile Googlebot. No desktop crawling.

Field data (75th percentile) is the ranking signal. Lab data is for debugging.
| Metric | Good | Needs Improvement | Poor | Notes |
|---|---|---|---|---|
| LCP (Largest Contentful Paint) | < 2.5s | 2.5s - 4.0s | > 4.0s | Time until largest visible element renders |
| INP (Interaction to Next Paint) | < 200ms | 200ms - 500ms | > 500ms | Replaced FID March 2024. Measures ALL interactions |
| CLS (Cumulative Layout Shift) | < 0.1 | 0.1 - 0.25 | > 0.25 | Unexpected layout movements |
Without CrUX data, estimate from page characteristics; common fixes for each metric in checks.md §6.
| Check | Points |
|---|---|
| LCP < 2.5s | 5 |
| INP < 200ms | 5 |
| CLS < 0.1 | 5 |
AI crawlers (GPTBot, PerplexityBot, ClaudeBot, etc.) do NOT execute JavaScript. They fetch raw HTML. Client-rendered content = invisible to AI. Googlebot does execute JS but deprioritizes it (separate rendering queue, days/weeks delay).
curl -s [URL]Main content text, headings (H1/H2/H3), navigation, structured data (JSON-LD), meta tags (title/description/canonical/OG), internal links.
SSR solutions per framework + extended scoring detail in checks.md §7.
| Check | Points |
|---|---|
| Main content in raw HTML | 8 |
| Meta tags + structured data in raw HTML | 4 |
| Internal links in raw HTML | 3 |
Sub-checks (detail in checks.md §8):
curl -o /dev/null -s -w 'TTFB: %{time_starttransfer}s\n' [URL]loading="lazy" below fold (NOT above), explicit width/heightasync/defer third-party, no render-blocking in <head>max-age=31536000 with content-hashed filenames; HTML short cache or no-cache with ETag/Last-ModifiedCF-Ray (Cloudflare), X-Cache (CloudFront), X-Served-By (Fastly)| Check | Points |
|---|---|
| TTFB < 800ms | 3 |
| Page weight < 2MB | 2 |
| Images optimized (format, size, lazy) | 3 |
| JS bundles reasonable (< 200KB compressed) | 2 |
| Compression enabled (gzip/brotli) | 2 |
| Cache headers on static resources | 2 |
| CDN in use | 1 |
Bing/Yandex/Seznam/Naver instant-indexing protocol. Google does NOT support but monitors. GEO relevance: ChatGPT and Bing Copilot both use Bing's index — faster Bing indexing = faster AI visibility.
