Example session with this skill installed
sitemend audit ./projects/marketing-site --vitals
- Read your context and instructions
- Compiled the sitemend
Audit complete. Crawled 42 pages via filesystem. Detected 12 findings across 5 stages. Core Web Vitals measured via localhost:3000.
SEO Audit Baseline: marketing-site
| Stage | Status | Findings | Impact |
|---|---|---|---|
| S1: Indexing | WARNING | 2 | High - 2 pages blocked by robots.txt |
| S2: Architecture | PASS | 0 | - |
| S3: Content | FAIL | 5 | Med - Duplicate H1 tags on /services |
| S4: Performance | WARNING | 3 | LCP > 2.5s on mobile |
| S5: Schema | FAIL | 2 | Missing Product schema on 2 pages |
Critical Findings
- S1-INDEX-BLOCKED:
/admin/dashboardand/temp-landingare listed in sitemap but blocked by robots.txt. - S3-DUPLICATE-CONTENT:
/services/web-designand/services/ui-uxshare 85% content similarity. - S5-SCHEMA-MISSING:
Productmarkup is missing from/products/enterprise-tierdespite pricing being visible.
Gate Status: Gate A (Index before content) is BLOCKED. Fix S1 findings before proceeding to content repairs.
Next steps
- Run
sitemend planto generate the repair batch for S1 Indexing issues. - Adjust
robots.txtto align with sitemap requirements. - Re-run audit to clear Gate A.

About this skill
Sitemend is an SEO repair system designed for developers who need to fix technical search issues without relying on vague checklists. Most SEO tools provide a list of problems but leave the implementation to you. This skill crawls your local codebase or dev server, identifies issues in a strict dependency order, and generates precise repair plans. It ensures you do not waste time optimizing content that search engines cannot index.
What it does
- Dependency crawling identifies indexing, architecture, and content issues in a logical sequence.
- Evidence-backed auditing uses real Lighthouse and crawler data to find broken links, missing schema, and performance bottlenecks.
- Automated repair planning groups findings into stage-ordered batches with exact file diff previews.
- Verification loops re-crawl the site after changes to confirm fixes and check for regressions.
- Schema validation tests structured data against actual page content to prevent deceptive markup.
How it works
- Run
sitemend auditto crawl the repository or dev server and establish a health baseline. - Use
sitemend planto view ranked findings and preview the specific code changes required. - Execute
sitemend apply <batch-id>to write the approved fixes to your source files. - Run
sitemend verifyto re-audit the site and ensure all critical issues are resolved.
Frameworks & tools
This skill uses Python 3, beautifulsoup4, lxml, and Lighthouse. It supports local filesystem crawls or HTTP crawls of live dev servers using Chrome/Chromium for JavaScript rendering.
Why this beats prompting it yourself
Generic prompts often suggest SEO "best practices" that are irrelevant to your specific crawl depth or indexing status. Sitemend enforces strict gates, like ensuring a page is indexable before suggesting content edits, preventing hours of wasted effort on unreachable pages.
Use cases
- Auditing a local repository to fix SEO technical debt before a production deployment.
- Identifying and merging orphan pages that are diluting site authority.
- Repairing broken internal link structures and redirect chains in a dev environment.
- Generating and validating JSON-LD schema based on existing page data.
Known limitations
Does not estimate search volume, keyword difficulty, or backlink counts. Requires a local Python environment and a running server for Core Web Vitals measurements.
