- Wants to improve crawlability
- SKILL.md covers Scope (Technical SEO), Initial Assessment, Best Practices and Common Issues, plus 2 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Site Crawlability is an agent skill from kostja94/marketing-skills. When the user wants to improve crawlability, fix orphan pages, or optimize site structure for search engines. Also use when the user mentions "crawlability," "crawl budget," "orphan pages," "internal links," "site structure," "site crawlability," "infinite scroll," "pagination," "masonry SEO," "AI crawler optimization," "GPTBot crawlability," "ClaudeBot crawlability," or "content not indexed." For internal links, use internal-links.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO, covering Technical SEO. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.
When your agent uses it
- Wants to improve crawlability
- Fix orphan pages
- Optimize site structure for search engines
- The user mentions crawlability
Example prompts
- “crawlability,”
- “crawl budget,”
- “orphan pages,”
- “/site-crawlability”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Site structure: Flat vs. deep hierarchy
- Framework: Next.js, static, SPA, etc.
- Key paths: Sitemap, robots.txt, API, static assets
What it can do on your machine
Read from SKILL.md and the folder at commit 8dd89c5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
developers.google.comvercel.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Site Crawlability loads about 2k tokens when it runs. Until then it costs about 114 tokens; SKILL.md has 879 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SEO Technical: Crawlability
Guides crawlability improvements: robots, X-Robots-Tag, site structure, and internal linking.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Scope (Technical SEO)
- Redirect chains & loops: Fix multi-hop redirects; point directly to final URL
- Broken links (4xx): Fix broken internal/external links; 301 or remove
- Site architecture: Logical hierarchy; pages within 3–4 clicks from homepage
- Orphan pages: Add internal links to pages with no incoming links
- Pagination: Prefer pagination over infinite scroll for crawlability
- Crawl budget: Reduce waste on duplicates, redirects, low-value URLs (see below)
- AI crawler optimization: SSR for critical content; URL management; reduce 404/redirect waste (see below)
Initial Assessment
Project context: Read root contextus.md when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.
Identify:
- Site structure: Flat vs. deep hierarchy
- Framework: Next.js, static, SPA, etc.
- Key paths: Sitemap, robots.txt, API, static assets
Best Practices
Redirect Chains & Loops
- Fix multi-hop redirects; point directly to final URL
- Loops: URLs redirecting back to themselves; break the cycle
Broken Links (4xx)
- Fix broken internal/external links; 301 or remove
- Audit regularly; update or remove broken links
Site Architecture
| Principle | Guideline |
|---|---|
| Depth | Important pages within 3–4 clicks from homepage |
| Orphan pages | Add internal links to pages with no incoming links; see internal-links for link strategy |
| Hierarchy | Logical structure; hub pages link to content |
Pagination vs Infinite Scroll
Problem: With infinite scroll, crawlers cannot emulate user behavior (scroll, click "Load more"); content loaded after initial page load is not discoverable. Same applies to masonry + infinite scroll, lazy-loaded lists, and similar patterns.
Solution: Prefer pagination for key content. If keeping infinite scroll, make it search-friendly per Google's recommendations:
| Requirement | Practice |
|---|---|
| Component pages | Chunk content into paginated pages accessible without JavaScript |
| Full URLs | Each page has unique URL (e.g. ?page=1, ?lastid=567); avoid #1 |
| No overlap | Each item listed once in series; no duplication across pages |
| Direct access | URL works in new tab; no cookie/history dependency |
| pushState/replaceState | Update URL as user scrolls; enables back/forward, shareable links |
| 404 for out-of-bounds | ?page=999 returns 404 when only 998 pages exist |
Reference: Infinite scroll search-friendly recommendations (Google Search Central, 2014)
Pagination (Traditional)
- Reference links to next/previous pages;
rel="prev"/rel="next"where applicable - Avoid dynamic-only loading; ensure links in HTML
Crawl Budget
Crawl budget is the number of URLs Googlebot will crawl on your site in a given period. Large sites (10,000+ pages) may waste up to 30% of crawl budget on duplicates, redirects, and low-value URLs.
| Waste source | Fix |
|---|---|
| Duplicate URLs | Canonical; consolidate; 301 to preferred |
| Redirect chains | Point directly to final URL |
| Parameter proliferation | Use rel="canonical"; consider Clean-param (Yandex) |
| Low-value pages | noindex for thin/duplicate; see indexing |
| Crawl traps | Avoid infinite URL generation (e.g. faceted filters) |
Sitemap: Include only indexable, canonical URLs. See xml-sitemap, canonical-tag.

AI Crawler Optimization
AI crawlers (GPTBot, ClaudeBot, PerplexityBot, etc.) now represent ~28% of Googlebot's crawl volume. Their behavior differs from search engines—optimizing for both improves GEO (AI search visibility). See generative-engine-optimization for GEO strategy. Vercel/MERJ study (Dec 2024):
| Factor | AI Crawlers (GPTBot, Claude) | Googlebot |
|---|---|---|
| JavaScript | Do not execute JS; cannot read client-side rendered content | Full JS rendering |
| 404 rate | ~34% of fetches hit 404s | ~8% |
| Redirects | ~14% of fetches follow redirects | ~1.5% |
| Content in initial HTML | JSON, RSC in initial response can be indexed | Same |
Recommendations for AI crawlability:
| Practice | Action |
|---|---|
| Server-side rendering | Critical content in initial HTML. Use SSR, ISR, or SSG. See rendering-strategies for full guide. |
| URL management | Keep sitemaps updated; use consistent URL patterns; avoid outdated /static/ assets that cause 404s. AI crawlers frequently hit outdated URLs. |
| Redirects | Fix redirect chains; point directly to final URL. AI crawlers waste ~14% of fetches on redirects. |
| 404 handling | Fix broken links; remove or redirect outdated URLs. High 404 rates suggest AI crawlers may use stale URL lists. |
Reference: The rise of the AI crawler (Vercel, 2024)
Common Issues
| Issue | Check |
|---|---|
| Redirect chains | Update links to point directly to final URL |
| Broken links | 301 or remove; audit internal and external |
| Orphan pages | Add internal links from hub or navigation; see internal-links for strategy |
| Infinite scroll | Provide paginated component pages; or replace with pagination for key content; see above |
| AI crawlers missing content | Ensure critical content in initial HTML; see rendering-strategies |
Output Format
- Redirect audit: Chains and loops to fix
- Broken link audit: 4xx links to fix
- Site structure: Orphan pages, hierarchy
- Pagination: Implementation for crawlable content
- AI crawler: SSR/URL/redirect checks if GEO or AI visibility is a goal
