Starting point is 00:00:00 This audio is presented by Hacker Noon, where anyone can learn anything about any technology. Navigating Advanced Web Scraping, Insights and Expectations, by Bright Data. Red exclamation mark disclaimer. This is the first article in a six-part series on advanced web scraping. Throughout the series, we'll cover everything you need to know to become a scraping hero. Below is a general intro, but the upcoming pieces will explore complex topics and solutions you won't easily find anywhere else. Web scraping has become a buzzword that's everywhere, publications, journals, and tech blogs. But what's it all about, and why is it so important? If you're here, you probably already know. And, you're also likely aware that

Starting point is 00:00:42 extracting data at the highest level is no easy task, especially since sites are constantly evolving to stop scraping scripts. In this first article of our six-part series, we'll tackle the high-level challenges of advanced web scraping. Grab your popcorn, and let's get started. Popcorn web scraping in short. Web scraping is the art of extracting data from online pages. But who wants to copy-paste information manually when you could automate it? High-voltage web scraping is usually performed through custom scripts that do the heavy lifting, automating what you do manually, reading, copying, and pasting info from one page to another, but at light speed and on a massive

Starting point is 00:01:20 scale. In other words, scraping the web is like deploying an efficient data mining boating to the vast lands of the internet to dig up and bring back information treasure. No wonder, scraping scripts are also called scraping bots. Robot here's how a bot performing online data scraping typically operates. 1. Send a request. Your bot, also known as scraper, requests a specific webpage from a target site. 2. Parse the HTML. The server returns the HTML document associated with the page, which is then parsed by the scraping script. 3. Extract information. The script selects elements from the DOM of the page and pulls

Starting point is 00:01:59 specific data from the nodes of interest. 4. Store it. The bot saves the pre-processed data in a structured format, like a CSV or JSON file. Or sends it to a database or cloud storage. Sounds cool, but can anyone do it? TLDR. Yes, no, maybe. It depends. You don't need a PH. D and data science are financed to get that data is the most valuable asset on earth. It's no rocket science and giants like Google, Amazon, Netflix, and Tesla prove it, their revenue relies heavily on user data. Warning warning. In the modern world, if something is free, it's because you are the product. Yep, this even applies to cheap residential proxies man detective. Awesome, but how does that relate to web scraping? Thinking face well, most companies have a website, which contains and shows a lot of data.

Starting point is 00:02:51 While most of the data businesses store, manage, and collect from users is kept behind the scenes, there's still a chunk that's publicly available on the sesites. For a concrete example, consider social media platforms like Facebook, LinkedIn, or Reddit. These sites host millions of pages with treasure troves of public data. The key is that just because data is visible on a site doesn't mean the company behind it is thrilled about you scooping it up with a few lines of Python. Man-technologist data equals money, and companies aren't just giving it away. Flying money here's why so many sites are armed with anti-scraping

Starting point is 00:03:25 measures, challenges, and protection systems. Companies know that data is valuable, and they're making ETF for scraping scripts to access it, so, why is it so difficult? Learning why retrieving online data is tricky and how to tackle common issues is exactly what this advanced web scraping course is all about. Graduation cap to kick things off, check out this awesome video by fellow software engineer Forrest Knight, https colon slash slash www. youtube.com.watch.v equals vxk6yprvg underscore o and embeddable equals true web scraping is a complex world, and to give you a glimpse of its intricacy, let's highlight the key questions you need to ask throughout the process,

Starting point is 00:04:08 from the very start all the way to the final steps. Magnifying glass, don't worry if we only scratch the surface here. We're going to delve deeper into each of these aspects, including the hidden tips and tricks most people didn't talk about shushing face in upcoming articles in this series. So, stay tuned. Eyes is your target site static or dynamic. Don't know how to tell, if the site is static, it means that data is already embedded in the HTML returned by the server. So, a simple combo of an HTTP client plus HTML parser is all you need to scrape it. Technologist but if the data is dynamic, retrieved on the fly

Starting point is 00:04:45 via AJAX, like in a spa, scraping becomes a whole different ballgame. Basketball in this case, you'll need browser automation to render the page, interact with it, and then extract the data you need. So, you only need to figure out if a site is static or dynamic and choose the right scraping tech accordingly, right? Well, not that fast. Thinking face with PWAs on the rise, the question is, can you scrape them? Man shrugging and what about AI-driven websites? Those are the questions you need answers for. Because trust me, that's the future of the web. Globe what data protection tech is the site using? If ANY, as mentioned earlier, the site might have some

Starting point is 00:05:25 serious anti-bot defenses in place like CAPTCHAs, JavaScript challenges, browser fingerprinting, TLS fingerprinting, device fingerprinting, rate limiting, and many others. Get more details in the webinar below. www.youtube.com.watch?v equals 4 y i 5 x k x a 7 i and embeddable equals true these aren't things you can bypass with just a few code workarounds. They require specialized solutions and strategies, especially now that AI has tackened these protections to the next level. Put in other terms, you can't just go straight to the final boss like in Breath of the Wild. Unless, of course, you're a speedrunning pro joystick. Do I need to optimize my scraping logic? And how?

Starting point is 00:06:11 Alright, assume you've got the right tech stack and figured out how to bypass all anti-bot defenses. But here's the kicker, writing data extraction logic with spaghetti code isn't enough for real-world scraping. You'll quickly run into issues, and trust me, things will break. Grimace you need to level up your script with parallelization, advanced retry logic, logging, and many other advanced aspects. So, yeah, optimizing your scraping logic is definitely a thing. How should I handle proxies? As we've already covered, proxies are key for avoiding IP bans, accessing geo-restricted content, circumventing API raid limits, implementing IP rotation, and much more. But hold up, how do you manage them properly? How do you rotate them efficiently? And what

Starting point is 00:06:56 happens when a proxy goes offline and you need a new one? In the past, you'd write complex algorithms to manually address those problems. But the modern answer is AI. Sparkles that's right, AI-driven proxies are all the rage now, and for good reason. Smart proxy providers can handle everything from rotation to replacement automatically, so you can focus on scraping without the hassle. You've got to know how to AI-driven proxies if you want to stay ahead of the game. How to handle scraped data? Great, so you've got a script that's firing on all cylinders, optimized, and solid from a technical standpoint. But now, it's time for the next big challenge, handling your scraped data. The doubts are, what's the best format to store it in? Open folder. Where to store it? Files?

Starting point is 00:07:41 A database? A cloud storage? Cityscape? After how often it should be refreshed? And why? Hourglass? How much space do I need to store and process it? Package? These are all important questions, and the answers depend on your project's needs. Whether you're working on a one-time extraction or an ongoing data pipeline, knowing how to store, retrieve, and manage your data is just as vital as scraping it in the first place. But wait, was what you did even legal and ethical in the first place? You've got your scraped data safely stashed away in a database. Take a step back, is that even legal? Grimace if you stick to a few basic rules, like targeting only data from publicly accessible pages,

Starting point is 00:08:21 you're probably in the clear. Ethics? That's another layer. Things like respecting a site's robots. TXT for scraping and avoiding any actions that might overload the server are essential here. There's also an elephant in the room to address. Elephant with eye-powered scraping becoming the new normal. There are fresh legal and ethical questions emerging. Brain and you don't want to be caught off guard or end up in hot water because of new regulations or eye-specific issues. Advanced web scraping? Nah, you just need the right alley. Mastering web scraping requires coding skills, advanced knowledge of web technologies, and the experience to make the right architectural decisions. Unfortunately, that's just the tip of

Starting point is 00:09:02 the iceberg. As we mentioned earlier, scraping has become even more complex because of AI-driven anti-baud defenses that block your attempts.
