Technical SEO for Developers Who Ship
You don't need marketing fluff. You need a fast, precise audit that tells you exactly which meta tags are broken, which schema is invalid, and which Core Web Vitals are failing. Then you fix it and move on.
Run your first technical auditTechnical Audit
Our crawler hits your page the same way Googlebot does and reports every SEO-critical element in a structured checklist. Missing title tags, duplicate meta descriptions, broken canonicals, noindex directives that shouldn't be there, redirect chains longer than two hops, and orphan pages with zero internal links.
Every finding links to the specific line of HTML causing the issue. No guessing, no vague suggestions. Just the data you need to open a PR and fix it.
- Title tag length, duplication, and truncation checks
- Meta description presence and character limits
- Canonical URL validation and self-referencing checks
- Robots meta and X-Robots-Tag directive auditing
- Redirect chain detection (301, 302, meta refresh)
- HTTP vs HTTPS mixed content warnings
Schema Validation
We parse every piece of JSON-LD on your page and validate it against Google's structured data requirements. Not just syntax validation, but semantic validation: is your Article schema missing a required author field? Is your Product schema using a deprecated property? We catch it before Google does.
Rich snippets in search results drive significantly higher click-through rates. A single missing field in your schema can disqualify your page from eligibility. Our validator surfaces required fields, recommended fields, and deprecated properties so you ship valid structured data every time.
- JSON-LD extraction and syntax validation
- Google-specific required field checking
- Deprecated property and type warnings
- Rich result eligibility prediction
- Support for 20+ schema types (Article, Product, FAQ, etc.)
Core Web Vitals
Core Web Vitals are a confirmed Google ranking factor. Our performance module measures LCP, CLS, and INP against Google's thresholds and provides specific, code-level recommendations for each metric.
Instead of generic advice like "reduce JavaScript," we identify the actual resources causing your LCP delay, the DOM elements triggering layout shifts, and the event handlers blocking interaction. You get the diagnosis and the fix path.
- LCP measurement with resource waterfall breakdown
- CLS detection with element-level shift attribution
- INP analysis with slow event handler identification
- TTFB and server response time checks
- Pass/fail grading against Google's thresholds
- Priority-ranked fix recommendations
Sitemap & Hreflang
Your sitemap is the map you hand to search engines. If it has broken URLs, stale lastmod dates, or missing pages, crawlers waste budget on dead ends and skip your new content. We parse your entire XML sitemap and cross-reference it against your live site to catch every mismatch.
For multi-language sites, hreflang validation is notoriously tricky. A single missing return link invalidates the entire tag set for that page pair. Our checker validates bidirectional links, language codes, and x-default settings across every locale you serve.
- XML sitemap parsing with URL status verification
- Missing page detection (indexed but not in sitemap)
- lastmod freshness and accuracy checks
- Hreflang bidirectional return link validation
- Language and region code format verification
- x-default tag presence and configuration
