TL;DR

To scrape ahrefs public data, use a scraping API that handles proxy rotation and header management to avoid bot detection. Use Python or Node.js to send requests to the AlterLab API, which returns the HTML or structured JSON of public pages without requiring manual browser configuration.

Why collect data from Ahrefs?

Ahrefs provides a wealth of public-facing SEO data and educational resources. Extracting this information allows data engineers to build competitive intelligence tools without manual effort.

Common use cases include: – Market Research: Tracking public SEO trends and keyword visibility across industry leaders. – Price Monitoring: Monitoring public pricing page updates for SaaS competitors. – Data Analysis: Aggregating public SEO guides and documentation to train internal LLMs or RAG systems.

Technical challenges

Scraping ahrefs.com is not as simple as sending a requests.get() call. Like most high-traffic data platforms, they employ anti-bot protections to prevent server overload and unauthorized data harvesting.

The primary obstacles include:

  1. IP Rate Limiting: Rapid requests from a single IP result in immediate 403 Forbidden errors.
  2. TLS Fingerprinting: Modern servers can tell if a request comes from a Python script or a real Chrome browser by analyzing the TLS handshake.
  3. JavaScript Execution: Some data points are rendered client-side, meaning raw HTML requests will return empty containers.

To solve this, you need a Smart Rendering API that can mimic human behavior, rotate residential proxies, and execute JavaScript when necessary.

Quick start with AlterLab API

The fastest way to start is by using the SDKs. Refer to the Getting started guide for full environment setup.

Python Implementation

Python is the industry standard for data pipelines. Using the alterlab library, you can fetch public pages in a few lines of code.

Python
import alterlab

client = alterlab.Client("YOUR_API_KEY")
response = client.scrape("https://ahrefs.com/example-page")
print(response.text)

Node.js Implementation

For developers building real-time dashboards or serverless functions, Node.js provides an asynchronous approach to data collection.

JAVASCRIPT
import { AlterLab } from "alterlab";

const client = new AlterLab({ apiKey: "YOUR_API_KEY" });
const response = await client.scrape("https://ahrefs.com/example-page");
console.log(response.text);

cURL Implementation

If you are integrating into a bash script or a different language, use a simple POST request.

Bash
curl -X POST https://api.alterlab.io/v1/scrape \
  -H "X-API-Key: YOUR_KEY" \
  -d '{"url": "https://ahrefs.com/example-page"}'

Extracting structured data

Once you have the HTML, you need to parse it. For ahrefs public pages, you can use libraries like BeautifulSoup (Python) or Cheerio (Node.js).

Focus on these common patterns: – Page Titles: Look for <h1> tags or <title> elements. – Pricing Tables: Target div containers with classes containing "pricing" or "plan". – Meta Data: Extract <meta name="description"> for SEO analysis.

Structured JSON extraction with Cortex

Manual parsing with CSS selectors is fragile. If Ahrefs changes a class name, your scraper breaks. Cortex AI solves this by using LLMs to extract data based on a schema, regardless of the underlying HTML structure.

Here is how to extract typed JSON data from a public page:

Python
import alterlab

client = alterlab.Client("YOUR_API_KEY")
result = client.extract(
    url="https://ahrefs.com/example-page",
    schema={
        "type": "object",
        "properties": {
            "title": {"type": "string"},
            "price": {"type": "number"},
            "rating": {"type": "number"},
            "description": {"type": "string"}
        }
    }
)
print(result.data)  # Typed JSON output

Cost breakdown

Pricing is based on the complexity of the request. For Ahrefs, we recommend T3 (Stealth) to ensure consistent delivery through anti-bot protections.

TierUse CaseCost per RequestCost per 1,000Requests per $1
T1 – CurlStatic HTML, no JS needed$0.0002$0.205,000
T2 – HTTPStandard pages with headers$0.0003$0.303,333
T3 – StealthProtected pages, anti-bot active$0.002$2.00500
T4 – BrowserFull JS rendering required$0.004$4.00250
T5 – CAPTCHACAPTCHA solving + JS rendering$0.02$20.0050

Note: AlterLab auto-escalates tiers. If T1 fails, the system promotes the request to T2, and so on. You only pay for the tier that succeeds. See full AlterLab pricing for more details.

Best practices

To maintain a healthy scraping pipeline and respect the target server, follow these rules:

  1. Respect robots.txt: Check ahrefs.com/robots.txt to see which public paths are restricted.
  2. Implement Jitter: Do not send requests at exact intervals. Add a random delay (e.g., 1–5 seconds) between calls to mimic human behavior.
  3. Use Specific Tiers: If you know a page is static, force min_tier=1 to save costs. If it requires JS, use min_tier=4.
  4. Header Rotation: Ensure your User-Agent strings are updated and varied.

Scaling up

When moving from 100 to 100,000 requests, raw loops will fail.

Batching: Use asynchronous requests in Node.js or asyncio in Python to handle multiple URLs concurrently. Scheduling: Use cron-based scheduling to pull data during low-traffic windows (e.g., 03:00 UTC) to reduce the likelihood of aggressive rate limiting. Webhooks: Instead of polling the API, configure webhooks to push results to your server the moment the scrape completes.

Key takeaways

– Scraping Ahrefs requires handling TLS fingerprints and IP rotation. – Python and Node.js are the most efficient languages for these pipelines. – Cortex AI removes the need for fragile CSS selectors by extracting structured JSON. – Auto-escalation ensures you use the cheapest tier possible for every request.

Frequently Asked Questions

Scraping publicly accessible data is generally legal, as established in cases like hiQ v LinkedIn. However, users are responsible for reviewing the site's robots.txt and Terms of Service, implementing rate limits, and avoiding private or authenticated data.
Ahrefs employs standard anti-bot protections, including header verification and IP reputation checks. AlterLab handles these by rotating residential proxies and managing browser fingerprints.
Costs range from $0.0002 for static pages to $0.004 for full browser rendering. With AlterLab's auto-escalation, you only pay for the specific tier that successfully returns the data.
