Prioritized fixes.
Plain English. Zero noise.

Most audit tools drop 200 issues on your dashboard and wish you luck. ItzSEO runs the full crawl, measures Core Web Vitals, validates schema — then Claude prioritizes every issue by impact and effort and explains the fix.

The 200-issue dump

Most audit tools list problems. They don't rank them.

You crawl a 142-page site. The tool returns 47 issues. Five are critical, fifteen are noise, and the rest sit in between. Without a priority, your team picks the easy ones and the critical ones stay broken.

What ItzSEO does

Crawl. Measure. Validate. Prioritize.

Full-site Playwright crawl

Real browser. Render-aware. Picks up JavaScript-rendered content. Bounded by tier (Free 25 pages, Starter 250, Growth 1,000, Agency 1,000, Scale 5,000).

Core Web Vitals

LCP, INP, CLS from both lab (Playwright) and field (CrUX). Per-page scoring. Mobile + desktop separately. Threshold-flagged.

Schema validation

Every JSON-LD block validated against schema.org. Invalid fields flagged with the line number. Suggested fix included.

Claude prioritization

Every issue scored by impact × effort. Critical = LCP > 4s on guide pages (high impact, hours of effort). Med = broken 404 links (medium impact, minutes). Surfaces what to fix first.

Plain-English fix steps

No “optimize TTFB.” You get ‘Your hosting's TTFB is 1.2s. Most likely cause: cold cache on dynamic queries. Fix: add Cloudflare full-page caching for /guides/*.’

FAQ

Technical Audits questions.

How long does a full-site audit take?

Bounded crawl: ~5 minutes for 100 pages, ~30 minutes for 1,000 pages. Background job — you don't have to keep the tab open. Email notification when complete. Larger sites should run audits weekly via the cron schedule rather than on-demand.

Does the crawler respect robots.txt?

Yes. We honor robots.txt by default + a 1-second crawl-delay between requests. Override only available on Agency+ if you confirm you own the domain (rare — useful for staging sites where you want to crawl despite a noindex).

What's the page limit?

Free: 25 pages. Starter: 250. Growth: 1,000. Agency: 1,000 (with 5 sites). Scale: 5,000 across all sites. Beyond Scale, contact us.

Do you check for JavaScript SEO issues?

Yes. Playwright renders the page in a real Chromium browser, so we catch JS-rendered content, lazy-loaded images, hydration mismatches, and CSR-only content. This is the main reason we're slower than crawler-only tools like Screaming Frog — accurate render matters more than speed.

Can I run an audit before signing up?

Single-page free at /tools/free-seo-audit (no signup). For multi-page audits, you need a Starter tier or higher. Free plan includes one Basic audit per workspace.

How is Claude prioritization different from rule-based severity?

Rule-based: ‘missing canonical = HIGH’. Claude: ‘missing canonical on a 24-page guide series with high traffic = CRIT, missing canonical on a stagnant tag page with 0 traffic = LOW.’ Context-aware. Same issue type, different priority based on impact.
