What it does

Indexability is an agent skill from thedaviddias/Front-End-Checklist. Use when auditing a site for accidental noindex directives, investigating why important pages are not appearing in Google Search, or reviewing CMS settings that control indexing at the page or category level.

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/rule.md`).

It sits in Marketing & SEO, covering Technical SEO and Web search. It works with Google Search Console. The repository describes itself as: 🗂 The essential checklist for modern web development, for humans and AI agents. The licence is MIT.

When your agent uses it

  • Auditing a site for accidental noindex directives
  • Investigating why important pages are not appearing in Google Search
  • Reviewing CMS settings that control indexing at the page

Example prompts

  • “/indexability”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. For pages with
  2. For pages with X-Robots-Tag: noindex HTTP header
  3. For pages blocked by robots.txt
  4. After removing blocks, request indexing in Google Search Console (URL Inspection → Request Indexing).
  5. Monitor the Coverage report over the following weeks to confirm the page moves to "Indexed".

What it can do on your machine

Read from SKILL.md and the folder at commit e8d14d0. 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):

    • frontendchecklist.io

    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

Indexability loads about 814 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 386 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~814
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.9k

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.

Make important pages indexable

A page blocked from indexing cannot appear in search results, regardless of its content quality or backlinks. Accidentally blocking key landing pages, product pages, or blog posts is one of the most impactful technical SEO errors — often silently losing significant organic traffic.

Quick Reference

  • Verify that pages you want ranked are not blocked by noindex, robots.txt, or X-Robots-Tag headers
  • Test indexability with Google Search Console's URL Inspection tool — 'URL is on Google' confirms indexing
  • Common accidental blocks: staging environments promoted to production, CMS default noindex settings, and overly broad robots.txt Disallow rules

Check

For each important page (homepage, key landing pages, product pages, top blog posts): (1) Check <meta name='robots' content='...'> — does it contain noindex? (2) Check X-Robots-Tag HTTP response header — does it contain noindex? (3) Check robots.txt — is the URL's path blocked by a Disallow rule? (4) In Google Search Console, use URL Inspection to confirm the page is indexed. Flag any important page with any form of noindex or robots.txt block.

Fix

  1. For pages with <meta name='robots' content='noindex'>:
    • Remove the noindex tag entirely, or change to content='index, follow'.
    • In Next.js: remove the robots: { index: false } from the page's metadata.
  2. For pages with X-Robots-Tag: noindex HTTP header:
    • Remove the header in your server config (Nginx, Apache, CDN rules).
    • In Vercel: check vercel.json headers configuration.
  3. For pages blocked by robots.txt:
    • Remove or narrow the Disallow rule.
    • Test with Google's robots.txt tester in Search Console.
  4. After removing blocks, request indexing in Google Search Console (URL Inspection → Request Indexing).
  5. Monitor the Coverage report over the following weeks to confirm the page moves to "Indexed".

Explain

A page that cannot be crawled or indexed cannot rank, no matter how good its content or how many links point to it. Google explicitly states that noindex and robots.txt blocks prevent pages from appearing in search results. Accidental indexing blocks are among the most common causes of sudden, unexplained drops in organic search traffic.

Code Review

Parse every page's HTML for <meta name='robots'> or <meta name='googlebot'> tags containing noindex. Check HTTP response headers for X-Robots-Tag with noindex. Cross-reference with robots.txt Disallow patterns. Flag any route in the application where noindex is set unconditionally (rather than conditionally for draft/private content).
