## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Bulk llms.txt & Technical SEO Checker

A bulk **llms.txt checker and technical SEO audit**: check hundreds of websites in one run for **AI-search readiness** (llms.txt, AI crawlers in robots.txt) and **technical SEO**. Each site gets a **0-100 score**, a letter grade and a **plain-English fix** for every problem found.

Built for agencies, freelancers and site owners who need a fast first look before a proposal, a migration or a monthly report.

**Try it on 10 websites for $0.05** (the free credit on Apify's free plan covers it).

### How to run it

1. Paste domains or URLs into **websites**.
2. Optional: set `onlyBelowScore` to keep only sites with problems, and `maxLinksToCheck` for the broken-link test.
3. Press **Start** and download the results as Excel, CSV or JSON.

### What it checks (homepage of each site)

| Area | Checks |
|---|---|
| **AI search** | Which AI crawlers `robots.txt` blocks (GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, PerplexityBot, Google-Extended, Applebot-Extended, CCBot and more), and whether an `llms.txt` file exists |
| **Indexing** | `robots.txt` present, Googlebot blocked, `noindex` on the homepage, XML sitemap found and URL count, sitemap listed in robots.txt |
| **On-page** | Title and length, meta description and length, H1 count, canonical tag, viewport, `lang`, Open Graph tags, hreflang count |
| **Structured data** | Every JSON-LD `@type` on the page (Organization, Product, FAQPage, LocalBusiness...) |
| **Security & speed** | HTTPS redirect, redirect count, response time, SSL certificate days left |
| **Broken links** | Internal links on the homepage that return 404, 410 or 5xx (login and cart links are skipped) |

### Real numbers: new Shopify stores

We ran it on 56 randomly picked Shopify stores launched in September–October 2026:

- **58%** had **no meta description** on the homepage.
- **58%** had a homepage title **shorter than 15 characters**, usually just the brand name.
- **19%** used **more than one H1**.
- Average score **93/100**: the platform handles the basics (sitemap, robots.txt, llms.txt, HTTPS), but the content fields are left empty.

### Input

```json
{
  "websites": ["apify.com", "https://www.example-store.com"],
  "maxLinksToCheck": 20,
  "onlyBelowScore": 80
}
```

- **websites**: domains or URLs. Duplicates are removed.
- **maxLinksToCheck**: homepage links to test for broken pages (0 turns it off).
- **onlyBelowScore** (optional): return only sites below this score. Sites filtered out are not charged.

### Output (one row per website)

```json
{
  "domain": "theverge.com",
  "score": 85,
  "grade": "B",
  "https": true,
  "responseMs": 1394,
  "title": "The Verge",
  "titleLength": 9,
  "metaDescriptionLength": 221,
  "h1Count": 0,
  "schemaTypes": ["EntryPoint", "ImageObject", "NewsMediaOrganization", "Person", "SearchAction", "Thing", "WebSite"],
  "robotsTxt": true,
  "googlebotBlocked": false,
  "aiBotsBlocked": ["ChatGPT-User", "ClaudeBot", "Claude-SearchBot", "anthropic-ai", "PerplexityBot", "Google-Extended", "Applebot-Extended", "CCBot", "Bytespider", "Meta-ExternalAgent"],
  "aiSearchBotsBlocked": ["ChatGPT-User", "Claude-SearchBot", "PerplexityBot"],
  "llmsTxt": false,
  "sitemapUrls": 69,
  "sslDaysLeft": 87,
  "linksChecked": 20,
  "brokenLinks": [],
  "issues": ["Title is 9 characters.", "Meta description is 221 characters.", "No H1 heading on the homepage.", "robots.txt blocks AI search crawlers: ChatGPT-User, Claude-SearchBot, PerplexityBot."],
  "fixes": ["Keep the title between 30 and 60 characters.", "Aim for 120-160 characters.", "Add one H1 that says what the business does.", "Allow OAI-SearchBot, Claude-SearchBot and PerplexityBot if you want to be cited in AI answers."],
  "status": "ok"
}
```

`aiBotsBlocked` lists every AI crawler the site blocks; `aiSearchBotsBlocked` is the subset that sends visitors from AI answers. Blocking training-only crawlers (GPTBot, ClaudeBot, CCBot, Google-Extended) is a business choice and is not penalised; blocking AI search crawlers is.

### Scoring

Starts at 100. Biggest deductions: Googlebot blocked −30, homepage `noindex` −25, no HTTPS −15, no title −10, SSL expiring within 14 days −10, broken links up to −10, no viewport −8, no meta description −6, no JSON-LD −6, AI search crawlers blocked −5, no sitemap −5, no H1 −5. Grades: A ≥ 90, B ≥ 75, C ≥ 60, D ≥ 40, F below.

### Pricing

**$5 per 1,000 websites audited** (pay per event `site-audited`). Sites that are unreachable, return an error or show a bot-protection page are **free**.

### Good to know

- Only the homepage is audited; the sitemap count follows up to 3 child sitemaps of a sitemap index.
- Sites behind bot protection are reported with their status and are not charged.

### FAQ

**What is llms.txt and does it matter?**
`llms.txt` is a proposed file that tells AI tools what a site is about. It is optional and Google doesn't use it; the actor simply reports whether it exists. Allowing AI *search* crawlers in robots.txt matters more if you want to be cited in AI answers.

**Does it crawl the whole site?**
No. It audits the homepage, robots.txt, llms.txt and the sitemap, and tests up to `maxLinksToCheck` homepage links for broken pages.

**Why was a site not charged?**
Sites that are unreachable, return an error or show a bot-protection page are listed with their status and are free.

**Do I need an API key?**
No. Only public pages are read.

## MCP server setup

```json

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
