What it does
Indexnow is an agent skill from kostja94/marketing-skills. When the user wants to implement IndexNow, notify search engines of new/updated URLs, or speed up Bing indexing. Also use when the user mentions "IndexNow," "Bing indexing," "URL notification," "instant indexing," "sitemap IndexNow sync," "share URL list with sitemap," or "IndexNow API." For sitemap SSOT, use xml-sitemap.
Its SKILL.md is about 880 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 implement IndexNow
- Notify search engines of new/updated URLs
- Speed up Bing indexing
- The user mentions IndexNow
Example prompts
- “IndexNow,”
- “Bing indexing,”
- “URL notification,”
- “/indexnow”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
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
Shell commands in SKILL.md call:
npm
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):
bing.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
Indexnow loads about 882 tokens when it runs. Until then it costs about 83 tokens; SKILL.md has 397 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: IndexNow
Guides IndexNow protocol integration for faster search engine indexing (primarily Bing).
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)
- IndexNow: Submit URLs to Bing/Yandex for faster indexing
- URL notification: Notify search engines of new or updated URLs
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 URL: Base domain
- URL source: Config file, sitemap, CMS, etc.
- Deployment: CI/CD, manual, or both
Overview
IndexNow notifies search engines (mainly Bing) of new or updated URLs to speed up indexing.
Implementation Steps
1. API Key and Verification
- Generate API key (e.g., UUID)
- Create verification file:
https://example.com/{key}.txt - File content: the API key string
- Configure key and URL in your IndexNow client
2. Submission Methods
| Method | When to use |
|---|---|
| Single URL | New or updated page |
| Batch | Many URLs at once (e.g., after deploy) |
| Relative paths | Convert to full URLs before submitting |
3. Best Practices
| Practice | Note |
|---|---|
| When to submit | New pages, major content updates, meta changes |
| When not to | Minor edits; let natural crawling handle |
| Frequency | Once per deploy; avoid excessive submissions |
| Priority | Submit high-value commercial pages first |
Show full SKILL.md (150 more words)Show less
4. CI/CD Integration
npm run build
npm run indexnow:all5. Single Source of Truth (URL List)
- Use same config as sitemap: Import URL list from central config (e.g.,
site-pages-config.ts) or sitemap generation logic. - Avoid: Separate hardcoded URL lists for IndexNow—leads to inconsistency and missed URLs.
- Feed: If you have RSS/feed, it can also consume from the same config to stay in sync.
Supported Search Engines
- Bing: Primary support
- Yandex: Supports IndexNow
- Google: Does not use IndexNow; use Sitemap + Search Console
Verification
- Check Bing Webmaster Tools for indexing status
- Monitor submission logs for errors
Common Issues
| Issue | Fix |
|---|---|
| Domain verification fails | Ensure URL uses correct domain |
| API key error | Verify key and verification file match |
| Network errors | Retry; API can be intermittent |
Output Format
- Setup steps: Key generation, verification file
- Submission flow: Single vs. batch
- Integration: CI/CD or manual script
- References: IndexNow docs
Related Skills
- xml-sitemap: Share same URL list from central config
- indexing: Broader indexing strategy
