## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use 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).


# README

## Bulk SEO Audit - Titles, Meta, Headings, Schema, Links

> The fastest bulk SEO meta tags and headings extractor — audit titles, meta descriptions, headings, canonicals, social cards, and schema across hundreds of URLs in one pass.

### What you get

Paste a list of URLs and get a complete on-page SEO snapshot for each one: title, meta description, heading hierarchy, canonical, robots directive, Open Graph and Twitter social cards, schema markup, image alt-text gaps, internal/external link counts, and word count. Designed for SEO consultants, content auditors, and in-house SEO teams who need real on-page data across hundreds of pages without firing up a desktop crawler.

### Output fields

| Field | Description |
|-------|-------------|
| `url` | The URL you submitted. |
| `final_url` | The URL after following redirects. |
| `status_code` | HTTP status code (200, 301, 404, etc.). |
| `title` | The `<title>` tag text. |
| `title_length` | Character count of the title (Google typically truncates over ~60). |
| `meta_description` | The meta description tag. |
| `meta_description_length` | Character count (Google typically truncates over ~160). |
| `meta_keywords` | The meta keywords tag (rarely used today). |
| `canonical` | The canonical URL declared by the page. |
| `robots_meta` | The meta robots directive (e.g. `index,follow`, `noindex`). |
| `viewport` | The viewport meta tag (mobile-friendliness signal). |
| `lang` | The `lang` attribute on the `<html>` tag. |
| `charset` | Character set declared by the page. |
| `h1_tags` | List of unique H1 headings on the page. |
| `h2_tags` | List of unique H2 headings on the page. |
| `h1_count` | Total H1 tags (more than one is an SEO smell). |
| `h2_count` | Total H2 tags. |
| `h3_count` | Total H3 tags. |
| `h4_count` | Total H4 tags. |
| `og` | Open Graph tags (`og:title`, `og:description`, `og:image`, etc.) as a flat dict. |
| `twitter` | Twitter card tags (`twitter:card`, `twitter:title`, etc.) as a flat dict. |
| `json_ld` | Parsed schema markup blocks (Product, Article, FAQ, Breadcrumb, etc.). |
| `images_total` | Total `<img>` tags on the page. |
| `images_missing_alt` | Images with no `alt` attribute (accessibility + SEO gap). |
| `internal_links` | Links pointing back to the same domain. |
| `external_links` | Links pointing to other domains. |
| `nofollow_links` | Links marked `rel="nofollow"`. |
| `word_count` | Visible word count (script and style content excluded). |
| `text_to_html_ratio` | Word count divided by HTML byte size — low values flag thin or template-heavy pages. |
| `response_time_ms` | Time to fetch the page in milliseconds. |
| `content_length` | HTML byte size. |
| `error` | Error message on failure (`null` on success). |
| `checked_at` | ISO timestamp when the audit ran. |

When a URL fails, the same shape is returned with `error` set and the numeric fields zeroed out.

### Input parameters

| Parameter | Required | Description |
|-----------|----------|-------------|
| `urls` | Yes | List of page URLs to audit. Each URL produces one result. |
| `timeoutSecs` | No (default `20`) | Maximum seconds to wait for each page (1–120). Slow pages report a `timeout` error. |
| `concurrency` | No (default `10`) | How many pages to fetch in parallel (1–50). |
| `userAgent` | No | The User-Agent header sent with each request. Override to mimic a specific bot or browser. |
| `proxyConfiguration` | No | Optional Apify proxy. Most public pages don't need one. |

### Use cases

- **SEO consultants** running on-page audits — surface every page missing a title, meta description, or canonical, and rank H1 issues across the whole site.
- **Content auditors** cleaning up legacy content — find thin pages by word count and text-to-HTML ratio, then prioritize rewrites.
- **In-house SEO teams** monitoring schema coverage — verify every product page has Product schema, every article has Article schema, and every FAQ page has FAQ schema.
- **Accessibility leads** finding images missing alt text — get a per-page count and prioritize the worst offenders.
- **Competitive researchers** comparing social previews — pull Open Graph and Twitter cards from a competitor's blog to see how they package shares.

### Limitations

- Captures the HTML the server returns. Pages that render their content entirely in the browser (heavy single-page apps) may show empty title, missing headings, or zero links — for those sites, use a browser-based scraper instead.
- Some sites rate-limit aggressive scraping. Use the proxy option if you start hitting 403s.
- Word count is computed from visible text after removing script and style content. Inline SVG and obscure HTML may slightly inflate or reduce the count.
- Schema markup blocks that are syntactically broken are skipped rather than failing the whole audit.
- Authenticated pages are not supported — this is for public URLs only.

### Compared to alternatives

| | Thirdwatch Bulk SEO Audit | typical "SEO On-Page Analyzer" actors on Apify Store |
|---|---|---|
| Open Graph + Twitter cards as structured dicts | Yes | Often title/description only |
| Parsed schema markup blocks | Yes (full JSON) | Often missing |
| Heading lists (not just counts) | Yes | Often only counts |
| Internal vs external vs nofollow link counts | Yes | Often "total links" only |
| Image alt-text gap count | Yes | Sometimes |
| Text-to-HTML ratio (thin-content signal) | Yes | Rarely included |
| Concurrency control | Up to 50 parallel | Often 5–10 |

### FAQ

**Does this respect robots.txt?**
This actor sends one request per URL and does not crawl. It uses a clearly identifiable User-Agent (`ThirdwatchSEO/1.0`) so site owners can recognize and rate-limit it if they want.

**What's the rate limit?**
You control it via `concurrency` (max 50). For sites you don't own, keep it low and enable the proxy option if you hit 429 or 403.

**Can I audit pages behind a login?**
No — this actor does not handle authentication, cookies, or session headers. It's designed for public URLs.

**Why are some fields empty on JavaScript-heavy sites?**
Single-page apps render content in the browser after the initial HTML loads. This actor reads the server-rendered HTML only. For React/Vue/Angular sites with no server-side rendering, use a browser-based audit tool instead.

**Does it parse every kind of schema markup?**
Yes — every `<script type="application/ld+json">` block is parsed and returned as structured data. Microdata and RDFa are not parsed.

### SEO meta tags and headings extractor for site-wide audits

Run a full on-page SEO audit across an entire site in minutes. Pair this with the [Sitemap URL Extractor](https://apify.com/thirdwatch/sitemap-extractor) to pull every URL on the site, then pipe the list into this actor for a complete title/meta/heading/schema audit.

For uptime, redirect, and SSL checks across the same URL list, combine with the [Bulk URL Status Checker](https://apify.com/thirdwatch/status-code-checker).

# Actor input Schema

## `urls` (type: `array`):

List of page URLs to audit. Each URL produces one result with title, meta description, headings, canonical, Open Graph, Twitter cards, schema markup, link counts, and word count.

## `timeoutSecs` (type: `integer`):

Maximum seconds to wait for each page to respond. Pages slower than this are reported with a timeout error.

## `concurrency` (type: `integer`):

How many pages to fetch in parallel (1–50).

## `userAgent` (type: `string`):

User-Agent header sent with every request. Override to mimic a specific browser or search-engine bot.
