Why Snapshot Scraping Is Costing You Money

Ah, remember the good old days of web scraping? Downloading our competitor prices meant logging into websites, copying prices into Excel, praying the prices wouldn’t change overnight, and calling it a day.

Of course, those days are long gone. Businesses who rely on “checking back later” just don’t stand a chance against competitors using real-time data.

Today’s market demands continuous observation and instantaneous reactions. It’s time to stop looking in the rearview mirror and start streaming live feed from the web.

Snapshot Scraping: How Does It Fail You?

Simply put, snapshot scraping is when you check a website once then store that data until the next time you want to check it again.

Think about how foolish that sounds. You pull data from a competitor’s website today at noon. You make a business decision based on that data. But at 12:01 PM, your competitor changes their price. You won’t know until you schedule your next data pull.

Say goodbye to lost sales while your competitors quietly change prices under the cover of night.

Online prices don’t just change once per day. Online prices can change dozens, hundreds, even thousands of times per day. Electronics, fashion, and travel are some of the most competitive industries with products that change prices dozens of times per day. During major shopping events like Black Friday and Cyber Monday, online retailers can change prices several times per hour.

If you rely on daily or weekly snapshots of pricing data, you could be basing business decisions off of outdated information. At Ziny, we’ve worked with clients that rely on daily scrapes. Those daily snapshots leave businesses literally losing thousands to hundreds of thousands of dollars each day.

So how does continuous monitoring solve that problem?

Continuous Monitoring: What You Need to Know

Continuous website observation solves these problems by constantly watching your target websites 24/7 and alerting you the INSTANT something changes.

Continuous monitoring isn’t about scraping more frequently. Sure, part of the solution is scraping websites multiple times per day instead of once per day. However, continuous solutions use intelligent software that can identify when something on a webpage has changed rather than scraping every fifteen minutes regardless if there have been any changes.

Take a look at these benefits of continuous scraping that every business should be aware of.

1. Accurate Change Detection

Continuous monitoring systems know exactly when and where your target data has changed on a webpage. So rather than scraping a webpage every hour on the hour whether there have been any changes, your continuous scraper will only scrape a webpage when something you care about has changed.

2. Built-In Scheduling

Sites often change prices at the same time each day. Your continuous monitoring system can identify these patterns and schedule more frequent checks when changes are happening more frequently.

3. Multi-Faceted Monitoring

Instead of monitoring a single price, modern website monitoring tools track prices along with stock availability, product descriptions, customer reviews, promotional messaging, and even competitor ads. Multiple points of data allow your business to make more informed decisions with every purchase.

4. Automated Actions & Alerts

Continuous monitoring tools can be leveraged to automate specific actions. Let’s say you want to be alerted any time one of your competitor’s prices drops BELOW your price. You can set up automated workflows that create alerts, compile reports, and even initiate price drops from your ecommerce software.

Price Monitoring & Continuous Scraping

When thinking about continuous vs. snapshot scraping, price monitoring is a great example to highlight the pros and cons of each methodology.

The average flight changes prices THREE times per day. Hotel rates change constantly based on “demand.” Relying on once-daily priced scrapes means you could be showing your customers a hotel that cost $100 yesterday but increased 40% since you last checked.

You know Amazon makes a lot of price changes, but did you know they average OVER 2 MILLION PRICE CHANGES PER DAY? When you’re up against marketplaces or other large online retailers, scraping once daily (or even weekly) puts you hopelessly behind.

And it’s not just about price matching anymore. By continuously monitoring pricing data, you can start to identify trends and behaviors. Who changes prices first? How long does it take for others to follow suit? What events trigger sale cycles? How do holidays affect pricing strategies? This data can help you create and fine-tune a powerful dynamic pricing strategy that helps your business sell more and keep prices competitive.

So why isn’t every ecommerce business using continuous monitoring for prices and more?

Why Continuous Monitoring is So Difficult

If continuous website monitoring is so amazing, what’s the holdup? The main challenge with any kind of web scraping is technical difficulty.

Bot Detection

You’re not fooling anyone by scraping websites continuously. Websites employ bot detection technologies that utilize machine learning to limit scrapers. These systems look at request rates, browser fingerprints, visitor behavior, and traffic origin. If your scraper is hitting websites thousands of times per day, you’re FAR more likely to get banned than if you were scraping weekly or monthly.

Scaling Infrastructure

When monitoring hundreds or even thousands of websites continuously, you need a system that can support those requests. Not only will you need infrastructure that can send out concurrent requests and process that data in realtime, but you’ll need to store all of that historical data. Then you’ll need to scale your system elastically when monitoring peaks (i.e. when you decide to monitor 10x more websites).

Accurate Data Collection

Unlike scheduled scrapes, continuous data monitoring can come with unwanted anomalies. Prices will accidentally be listed as $0. Websites will show different products to you than they show someone visiting from an iPad. Gift cards will temporarily sell out due to website glitches. Your data monitoring system needs to differentiate between important changes and false positives.

Legal Limitations

Pushing the limits of bot detection systems and making huge volumes of requests against websites can come back to bite you. Many websites prohibit aggressive scraping in their Terms of Service, and overzealous web scrapers can even find themselves in violation of Computer Access Laws. Continuous monitoring should always be cautious of how many requests you’re making against websites and avoid disruptive scraping practices.

Proxies: The Bottleneck of your Continuous Monitoring Setup

Your IP address is the number one problem with any continuous monitoring operation.

We might get away with scraping a website once, but try scraping it every five minutes from the same IP address and you’ll get banned instantly. Website operators can easily identify high-frequency scraping operations just by analyzing the REQUEST RATE from each visitor.

Continuous monitoring needs to scrape websites frequently. But you can’t do that effectively from a single IP address.

Proxy management is your saving grace.

Proxies act as your web monitoring tools disguise. By rotating between thousands of unique IP addresses, it appears like your monitoring system is a herd of unique visitors instead of a single bot. But not all proxies are created equal.

Datacenter proxies are cost-effective and fast, but easily detected by bot prevention systems. Free proxies often don’t work at all (and sometimes belong to hackers). Residential proxies are great… if you have unlimited budget and don’t mind waiting minutes for each request to load.

For true continuous monitoring, you need access to a proxy network that offers:

Large Proxy Pools – The more IPs you have at your disposal, the less scraping you’ll have to do per IP. A small proxy pool will burn through IPs quickly.

Geographical Diversity – To target local-based content and appear natural, you’ll want proxies from every region around the world.

High-Uptime – All of your proxies need to work. There’s nothing worse than setting up a monitoring schedule only to have 25% of your proxies down.

Blazing Fast Speeds – Continuous data monitoring needs fast proxies. If it takes 5 minutes to load EACH request, that doesn’t leave you scraping many websites each day.

Ziny has you covered on ALL of the above. Our residential proxy network is specially designed for intensive data monitoring. We’ve got you covered with automatic IP rotation, cookie.js support, unlimited traversal of bot prevention systems, and elastic scaling options.

Stop Letting Cheap Proxies Limit You

If you’ve tried to create a continuous monitoring setup before, you know how difficult and painful that process can be. Bad proxies are the number one reason continuous monitoring systems fail.

Low-quality proxies lead to bans. Bans lead to missing data. Missing data means useless monitoring efforts.

Don’t let sub-par proxies hold your business back. Trust the experts for your proxy infrastructure needs and let Ziny power your continuous monitoring efforts.

Setting up your Continuous Monitoring Strategy

Alright, you’re ready to level up your game from stale snapshots to live streaming… now what?

Identify Key Targets

Don’t waste time monitoring websites that don’t matter. Know your competition. Know your price-sensitive products. Know which metrics matter most to your business and build your monitoring around that data.

Monitor Smart, Not Hard

Just because you’re now using “continuous” monitoring doesn’t mean you have to check websites every five minutes. Monitor heavily where you need to and lighten up where you don’t. Some products may need to be monitored hourly, while others may be just fine with twice-per-day scrapes. Implement smart scheduling.

Use Layered Alerts

Not every change needs your immediate attention. Set up different levels of alerts. If a competitors price drops below yours, you may want to be alerted RIGHT NOW. However, if a product suddenly goes out of stock, you may only care about receiving a daily summary. Minor changes like updates to product descriptions can wait until weekly summaries.

Integrate With Your Ecosystem

information you gather from monitoring trips wasted unless you use that data to make business decisions. Integrating your monitoring system with your pricing engine, inventory management, and business intelligence platforms can create powerful workflows that automate tasks and drive your business forward.

Plan for Expansion

Start small, but plan for success. Chances are you won’t monitor 10,000 websites right out the gate. But as your monitoring program grows and proves its value, you’ll want to expand. Build a foundation that can support that kind of growth.

Use Continuous Monitoring to Gain a Competitive Advantage

Monitoring websites continuously is a game-changer. You’re no longer flying blind and relying on historical data. You have instant access to the market right in front of you.

The more you monitor, the more data you’ll collect. Every day your monitoring system runs, you’re gathering valuable intel that no one else can see. You’ll start to identify patterns and behaviors. You can begin to anticipate what your competitors will do next rather than reacting to what they’ve already done.

Investing in the right tools and infrastructure to support continuous data monitoring (including a high-quality proxy network) can empower you to make better pricing decisions, manage your inventory more efficiently, and out-compete the businesses who blindly rely on outdated data.

Snapshot Scraping vs. Continuous Monitoring: Look Ahead, Not Back

Switching from traditional “snapshot” scraping to continuous data monitoring isn’t just updating your software. It’s transforming the way you compete with others in your industry.

Instead of trying to react to what your competitors did yesterday, you’ll have all the information you need to predict what they’re doing today, and what they’ll do tomorrow.

It takes dedication, yes. A solid proxy provider, DEFINITELY. But if your business plans on taking advantage of competitive intelligence and data-driven decisions, continuous website monitoring isn’t just important, it’s REQUIRED.

The digital world isn’t going to slow down to accommodate businesses that only look at website data once per day. Product prices are changing RIGHT NOW. Inventory is selling OUT RIGHT NOW. Market opportunities are being missed every day businesses wait to make decisions.

Continuous website monitoring isn’t the future. Continuous monitoring is here. Don’t get left behind.
