💡 What is the FAQ & Help Center Scraper with Change Monitor?

The FAQ & Help Center Scraper with Change Monitor is a powerful Apify actor that crawls any documentation site, knowledge base, or help center – and extracts all valuable content in a clean, structured format.

Unlike generic scrapers, this actor is built for RAG pipelines and AI‑ready data extraction:

• Automatic FAQ extraction – identifies question‑answer pairs from any page (using headers, buttons, and question patterns).
• Content change detection – tracks modifications via content hashing, logs New, Modified, or Unchanged status, and records times changed.
• Rich metadata – word count, reading time, author, published/last modified dates, breadcrumbs, product area, audience (developer vs general).
• Code & media awareness – counts code snippets, detects images and videos.
• Related articles discovery – finds internal recommended links.
• Pay‑per‑result pricing – only charged for successfully scraped pages ($0.007/page). Start cost $0.02.

Ideal for:

• RAG‑pipeline‑data ingestion (e.g., loading into vector databases)
• Documentation‑scraper for AI training or retrieval
• Change‑detection monitoring (e.g., alert when a critical help page changes)
• Web‑monitor for competitor documentation updates
• faq‑scraper to build automated FAQ datasets

💰 Pricing

Component	Price
Actor start (per run)	$0.02
Per successful page result	$0.007
Per 1,000 successful pages	$7.00

• You are charged only when a page is successfully scraped (i.e., content extracted, no error).
• Failed pages (blocked, 404, network timeout) cost nothing.
• Actor start fee covers infrastructure even if zero pages are scraped.
• Example: 500 successful pages = $0.02 + (500 × $0.007) = $3.52.
• Example: 2,500 successful pages = $0.02 + (2,500 × $0.007) = $17.52.

Change detection is free – the actor computes hashes and tracks changes without extra cost. You only pay for the initial scrape of each page; subsequent runs that re‑scrape the same page (if not changed) still incur a charge (since you are retrieving fresh HTML and processing it). To reduce costs, use maxItems and schedule runs only when needed.

🛠 How to Use on Apify

1. Create a task with this actor.
2. Provide start URLs – the root of the documentation or help center (e.g., https://docs.stripe.com/, https://support.google.com/).
3. Set maxItems – how many pages to scrape (default 100, maximum limited by website size).
4. Adjust concurrency – higher concurrency speeds up crawling but may increase blocking risk.
5. Enable residential proxies – strongly recommended to avoid rate limiting.
6. Run – the actor will crawl, extract, detect changes, charge per page, and push results to dataset.
7. Export – download JSON, CSV, or Excel.

Change detection across runs: The actor saves content hashes in key‑value store. When you rerun with the same start URLs, it will compare hashes and set change_status accordingly.

❓ Frequently Asked Questions

1. What is a “successful result” for PPE charging?
A page is considered successful if the actor can extract its HTML and parse at least a title and some content. Failed pages (404, Cloudflare block, timeout) are not charged.

2. How does change detection work?
The actor computes an MD5 hash of the page’s main content. If the hash differs from the previous run’s stored hash, change_status becomes Modified and times_changed increments. If the page was not seen before, change_status is New. If the hash matches, it is Unchanged.

3. Are FAQ questions and answers always accurate?
The actor uses heuristic rules (question marks, question‑word lists, HTML structure). Accuracy is high for well‑structured documentation, but you may get false positives. You can filter by question_count or manually review.

4. Do I need residential proxies?
For small documentation sites (<100 pages), datacenter proxies may work. For large sites (Stripe, Google, etc.) or frequent runs, residential proxies are strongly recommended to avoid 429 and CAPTCHA blocks.

5. What does the content_text field contain?
It contains the extracted main text from <main>, <article>, or the body, cleaned and truncated to 1500 characters in the JSON output. The full text is stored in the dataset item, but the displayed output in the console may truncate it.

6. How do I run change detection on a schedule?
Create an Apify schedule that triggers this actor every day or week. The actor will load the previous state from the key‑value store and only push pages that have changed (if you want to reduce costs, you can filter out Unchanged pages in post‑processing).

7. Can I limit crawling to a specific sub‑path?
Yes. The actor only follows links that stay within the same domain. If you want to restrict to a sub‑path (e.g., /docs/ only), you must provide a start URL that is already within that path and rely on the fact that the actor respects the same‑domain rule. It does not have a path‑prefix filter.

8. What is the audience field?
If the page contains code snippets (<pre> or <code>), it is classified as Developers/Merchants. Otherwise, General Users.

9. How long does a run take?
For 1,000 pages, with concurrency set to 15, expect roughly 5–10 minutes, depending on network latency and proxy speed.

10. What happens if the actor hits the spending limit?
The actor checks charge_result.event_charge_limit_reached after each page and stops gracefully. It saves state so that when you restart (after increasing budget), it will resume without re‑scraping already processed pages.
