## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.
Actors are written with capital "A".

## 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.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## Website SEO Audit

A comprehensive SEO audit tool that crawls websites and identifies technical SEO issues, content gaps, and optimization opportunities. **Works without any external API keys** — all core SEO checks use built-in rule engines. Optional AI enhancement available for advanced recommendations.

### Features

#### Core SEO Audit (No API Key Required)

- **Crawl & Scan**: Automatically crawls up to 50 pages of your website
- **Technical SEO Checks**:
  - Title tag length validation (optimal: 10-70 characters)
  - Meta description presence and length (optimal: 50-160 characters)
  - H1 / H2 heading validation and count
  - Canonical tag correctness
  - Image alt text completeness
  - Mobile viewport meta tag detection
  - Robots noindex detection
- **Broken Link Detection**: Checks internal links for 4xx/5xx errors (up to 15 per page)
- **SSL Certificate Analysis**: TLS version, cipher, certificate expiry
- **Security Headers**: HSTS, X-Frame-Options, CSP, Referrer-Policy
- **Open Graph Tags**: Facebook/social sharing meta tags
- **Schema.org Structured Data**: JSON-LD detection
- **Sitemap Discovery**: Via robots.txt
- **Rule-Based Scoring**: 0-100 SEO score calculated from detected issues (no AI needed)

#### Optional AI Enhancement

- **Enhanced Recommendations**: Enable `useAI` for Kimi AI-generated prioritized fix lists and deeper analysis
- Requires `KIMI_API_KEY` environment variable (set in Apify Console)
- When disabled: all scoring and recommendations are generated by built-in rules — faster, zero AI cost, no external dependencies

### Input Parameters

|-----------|------|---------|-------------|
| `url` | string | — | **Required.** Website URL to audit (e.g. `https://example.com`) |
| `maxPages` | integer | 10 | Maximum pages to scan (1-50) |
| `checkBrokenLinks` | boolean | true | Check internal links for 4xx/5xx errors |
| `checkMobileFriendly` | boolean | true | Analyze mobile viewport meta tag |
| `useAI` | boolean | **false** | Enable Kimi AI enhancement (requires KIMI\_API\_KEY). **Default OFF** for zero-cost, stable runs. |

### Use Cases

- **Pre-launch audits**: Check new websites before going live
- **Competitor analysis**: Audit competitor sites for SEO insights
- **Regular monitoring**: Periodic health checks of your web properties
- **SEO agencies**: Batch audits for client onboarding
- **Developers**: Quick technical SEO validation in CI/CD pipelines

### Pricing

This Actor uses **Pay-per-Event** pricing:

- **Actor Start**: FREE — no charge to start the run
- **Successful Audit**: $0.08 per successfully audited page
- **Failed pages**: FREE — no charge if a page cannot be accessed or times out
- **No AI costs**: Built-in rule engine is free; optional AI enhancement is billed separately via your own Kimi API key (not included in Actor pricing)

A typical 10-page audit costs **$0.80** (if all pages succeed). Failed or timed-out pages are not charged.

### Requirements

- **No API key required** for core SEO audit functionality
- **Optional**: Set `KIMI_API_KEY` environment variable if you want AI-enhanced recommendations (set `useAI: true` in input)

### Limitations

- Cannot audit JavaScript-rendered SPAs (React, Vue, Angular) — static HTML only
- Broken link check limited to 15 links per page (performance optimization)
- Page fetch timeout: 15 seconds per page
- SSL check requires port 443 to be open
- AI enhancement requires valid KIMI\_API\_KEY and may fail gracefully (falls back to rule-based scoring)

### Support

For issues or feature requests, please open an issue on GitHub or contact the developer via Apify messaging.

**Built with**: Apify SDK, BeautifulSoup, Requests, Python (core); Kimi AI (optional enhancement)
