## 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.

For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt).

### FAQ

**Q: How many URLs can I analyze in one run?**
A: No hard limit. Processing time and cost scale linearly with URL count. Typical runs analyze 10-1,000 URLs. For very large sites (10K+ pages), split into multiple runs.

**Q: What is the SEO score based on?**
A: Weighted scoring across all checks: title optimization (15pts), meta description (10pts), heading structure (10pts), image alt coverage (10pts), link health (10pts), technical SEO (15pts), structured data (10pts), social meta (10pts), and more. Each check has a clear pass/fail with points breakdown.

**Q: Can I use this in CI/CD pipelines?**
A: Yes. Trigger the Actor via Apify API and check results programmatically. Perfect for automated SEO regression testing before deployments. Integrates with GitHub Actions, Jenkins, and any webhook-capable CI system.

**Q: Does this check page speed or Core Web Vitals?**
A: No. This Actor focuses on on-page SEO factors (content, metadata, structure). For performance metrics, use Google PageSpeed Insights or Lighthouse.

**Q: Can I export results to CSV or Google Sheets?**
A: Yes. Apify datasets can be exported as JSON, CSV, Excel, or pushed directly to Google Sheets, Slack, email, or any webhook endpoint.

### Pricing

Pay Per Event -- charged per URL analyzed. Typical cost: $0.01-0.10 per URL depending on page complexity. Free Apify tier available for testing.

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).
