Solid data is an invaluable business asset, so it’s no surprise that there’s an entire industry built around its collection. You can find countless companies offering large databases you can use to tap into your addressable market and fill your pipeline with qualified leads. Such databases often come with hefty investments, though, so you might resort to web scraping as an alternative.

Unfortunately, you’ll likely run into a considerable issue—web scraping can be laborious and time-consuming, causing you to waste resources.

The good news is that you can take various steps to create an automated web scraping workflow. In this guide, we share some of the most effective tips based on our own extensive experience, as well as the best practices used by industry leaders in our network.

How To Automate Web Scraping Using Python

Python is a common choice when it comes to data scraping, so we’ll start by focusing on this technique. If you have the necessary coding background, you can build a Python scraper by installing specific libraries like AutoScraper and defining the relevant parameters.

Still, this may not be enough to create a fully automated scraper. For a hands-off workflow, you’ll also want to check the following boxes:

  1. Pagination handling
  2. User agent and proxy rotation
  3. CAPTCHA solving
  4. Auto retry mechanisms
  5. Scheduled scraping

Pagination Handling

Pagination is the process of splitting content into more manageable segments to ensure a better visual appeal and clarity. You’ve almost certainly encountered it while browsing the web—each time you saw numbered pages or the “show more” button, you ran into pagination.

Pagination can be a significant scraping challenge because it requires manually navigating different pages to scrape their contents individually. Doing so wastes a ton of time, so you need to automate the process.

The specific automation steps will largely depend on the type of pagination. Some of the most popular forms include the following:

  • Next/Previous buttons 🔙
  • Numeric pagination 1️⃣
  • Load More button ⬇️
  • Infinite scroll ♾️
  • Arrow-based pagination ▶️

After you’ve figured out the pagination type, you can adapt your scraper accordingly. For example, if the website uses numeric and/or arrow-based pagination, you’ll inspect the buttons and instruct the scraper to fetch links from them and visit them to keep scraping.

Note that this is a simplified example, and the actual steps involve considerable coding skills. Still, investing time in pagination handling can overcome a massive limitation, so it’s worth the effort.

User Agent and Proxy Rotation

While web scraping is technically legal, many webmasters frown upon it. That’s why they implement anti-scraping measures, which recognize automated actions and block those who try to perform them.

To overcome this issue, you can rotate user agents and proxies. Before we dive into the specifics, you can check the following table for definitions of both terms:

Term Definition
➡ User agent A piece of information/text that communicates which software or browser is making a request from a website
➡ Proxy A gateway between the client and the server that provides a requested resource

By rotating user agents and proxies, you can evade scraping counter-measures—here’s how this happens:

  • Rotating user agents makes the website think that requests are coming from different browsers or devices
  • Proxy rotation ensures that you can keep scraping if your IP address is blocked 

You can use the Tor browser to rotate proxies, though a Python Tor client like Torpy should also do the trick. As for user agent rotation, you can set it up manually by making a list of different user agents and then randomizing it so that a different one is used each time you start the scraping process.

CAPTCHA Solving

We’ve all solved a CAPTCHA or two while browsing the web, so they need no introduction. As frustrating as they might be, they’re quite useful for distinguishing between human users and bots, which helps them ward off malicious traffic.

Source: Google

Sadly, this also means they can prevent automated scraping. If your scraper can’t get past a page’s CAPTCHA, you’re out of luck because you can’t extract data from it.

The best way around this is to use captcha-solving services like 2Captcha or Anti-Captcha. Such services offer APIs you can use to integrate them with your scraper, letting you sit back and relax as the tool automatically passes the necessary checks.

The downside here is that CAPTCHA solvers typically come at a price. This makes sense because they involve advanced technologies like OCR, but not everyone might have room in their budget to invest in an automated solver.

Auto Retry Mechanisms

When your scraper sends a request to a website and it doesn’t succeed, you’ll see a 4xx or 5xx status code. Some of the most common codes are shown in the following table:

Status Code
What It Means
403 Forbidden The server got the request but can’t fulfill it because you don’t have the necessary access or permissions
404 Not Found The server couldn’t find the requested page
502 Bad Gateway The proxy got an invalid response from another server
503 Service Unavailable The server can’t fulfill the request due to maintenance or overwhelm

To ensure your scraper doesn’t give up when it gets one of these status codes, you need to use a so-called retry wrapper. You can either implement a pre-built wrapper or write a custom one from scratch.

Either way, you’ll need to configure two important parameters:

  1. Number of retries—Some status codes, such as 503, are temporary, so you might want to set more retries for the scraping to succeed once the issue is resolved
  2. Delay—Defines the time that passes between retries and should be optimized to ensure there aren’t too many attempts in a short time span that would overload the server

These parameters can vary greatly depending on the specific status codes, so there’s no one-size-fits-all solution.

Scheduled Scraping

There’s a high chance you’ll want to scrape a website more than once because doing so ensures you always have up-to-date information. While you can run multiple scrapes manually, a much better alternative is to schedule scraping according to your preferred cadence.

To do this, you’ll need to set up so-called cron jobs, which will allow your script to run without your direct involvement. You can do this by using a package like Crontab, after which you can write the code that will let you schedule specific scraping tasks.

The Downsides of Automating Web Scraping With Python

As you can see, it’s more than possible to avoid manual scraping by creating a comprehensive Python scraper that does the heavy lifting for you. The problem here is that it can take a lot of time and work before you reach the automation point.

Each of the above steps is highly technical and complex, so you may not be able to do it all independently unless you have extensive experience with Python.

You can pay a developer to build a scraper for you, but you’ll still need to learn how to use it (or train your team to scrape the web with it). The learning curve may not be worth it, especially when there’s a much more convenient alternative—using a commercial web scraping tool.

How an Automated Web Scraper Uplevels Your Data Collection

Many marketing and sales pros lack a coding background or don’t want to bother with creating a web scraper from scratch. If you’re among them, you can leverage a dedicated tool that makes the scraping process fast and simple.

Some of the main advantages of using such a tool include the following:

  • 🚀 Easy deployment—Many web data scrapers are ready to use out-of-the-box without the need for complicated setups or manual configuration
  • 🔢 Data organization—A solid web scraping tool automatically organizes data to your liking and gives you several export options
  • 📈 Scalability—As commercial web scrapers don’t require any specialized knowledge, they can be used by all the relevant team members without excessive training

Now, this doesn’t mean any web scraper will do the trick. There are various tools that only automate some aspects of web scraping while still requiring quite a bit of human input. That’s why you should research different options carefully before making any commitments.

How To Find the Right Web Scraper

When browsing web scrapers, you can zero in on the best platform by focusing on the following criteria, outlined in the table below:

Criteria Why It Matters
🖥️ A visual/no-code interface If you want to minimize the input necessary for scraping web pages, a no-code scraper is your safest bet. The only downside is that you may not have as much flexibility, but a solid platform should still let you scrape all the data you need
💰 Your budget Some web scrapers come at a hefty price, damaging your ROI. Luckily, there are numerous cost-effective solutions on the market, so examine each platform’s value for money before making the final decision
🧑‍💼 Your team size Some web scrapers offer per-person plans, which means the total cost can be quite high if you have multiple team members or plan on expanding your team
🧩 Integrations Data scraping is only the first step of an outreach workflow, so you must think about what happens next. Choose a platform that won’t expose you to manual data organization or exports by integrating with your current tech stack

If you need a platform that checks all the necessary boxes and gives you countless data points without huge investments—Clay can be an excellent choice. 🌈
