Imagine needing to check the price of a pair of shoes every five minutes. A store manager would quickly get suspicious and might even ban you. Web scraping is how you hire thousands of different people to visit that store and check the pricing one at a time.
The challenge: Website owners have become increasingly sophisticated at detecting these automated visits. If you run too many requests from the same IP address, anti-bot mechanisms will quickly shut down your scraper with a 403 Forbidden or 429 Too Many Requests error, preventing you from collecting the data you want.
If your business depends on large-scale data collection, a proxy server is essential. It acts as a middleman, routing your web scraper through millions of unique IP addresses to ensure it appears as many different users instead of a single bot making the same request over and over.
However, some proxy types are more likely to be blocked than others, and they aren't the perfect solution for every web scraping problem.
Web scraping requires a strategy to avoid detection. High-quality proxy servers act as a crucial middleman, routing your requests through millions of unique IP addresses to bypass sophisticated anti-bot mechanisms.
The core benefits of web scraping with a proxy
Proxy servers have a number of use cases in 2026, but web scraping is at the top of that list. If a business is looking to collect a large volume of data from various websites or apps, using a proxy company with access to millions of IP addresses is the most effective way to do it.
Anonymity and bypassing blocks
The chief reason to use a proxy server for web scraping is that it allows you to get around a website’s anti-bot mechanisms. Bot blockers are designed to detect behavior that doesn’t resemble that of a real user. Without a proxy, you may be able to run a few scraping requests initially, but you’ll inevitably get hit with a 403 Forbidden or 429 Too Many Requests error as soon as the blocker detects automated traffic.
With pools of millions of IP addresses, proxy companies allow you to avoid this issue altogether by using different IPs for each request. It also keeps the source of the request anonymous because it’s routed through the proxy. Keep in mind, not all IPs are created equal, and some proxy companies use proxies that are still likely to get blocked. The best proxy servers have a higher share of proxy pools with high-quality IPs, which are more likely to be recognized as legitimate by bot blockers.
Geographic targeting
Another advantage of proxy servers is that they allow you to choose from thousands of locations worldwide. When I tested Decodo’s proxies, for instance, I was able to identify specific ZIP codes in the US where the servers were located.
Geotargeting is especially useful for gathering data on e-commerce websites that use dynamic pricing. Companies like Amazon change their prices, availability and shipping options based on the shopper’s location. By using proxy servers all over the world, you’re able to compare different pricing strategies across markets.
Concurrent requests
Another major advantage of using proxy servers is their ability to run simultaneous web scraping requests across different IP addresses, rather than waiting for one request to complete before starting the next one. Our pick for the best overall proxy server, Oxylabs, offers 100 concurrent sessions per IP address you purchase. You’ll still have to pay for how much data you use with every proxy company, but these enable you to scrape thousands of pages at the same time without a problem.
Comparing types of proxies for scraping
Spend any time shopping around for proxy servers, and you’ll find an overwhelming number of options available. It comes down to which devices are being used as the proxy server -- some are less likely to be blocked than others, but you’ll pay more for them. Here are some of the most common types, from highest to lowest quality.
Mobile proxies
Mobile proxy servers use devices connected to real wireless carriers. They’re generally considered to be the highest-quality IPs and the least likely to be blocked. If you’re going to be doing web scraping on sophisticated targets like social media sites or e-commerce sites that are more likely to screen out automated requests, mobile proxies are the way to go.
Common use cases:
- Social media scraping
- E-commerce scraping
Residential proxies
Residential proxy servers are connected to real devices with IP addresses assigned by internet service providers (ISPs). They’re the most commonly used type of proxy server because they blend high-quality IPs with large proxy pools. Oxylabs, for instance, has more than 175 million residential proxies worldwide.
Common use cases:
- Web scraping
- Ad verification
- Limited-edition purchases
ISP proxies
You’ll sometimes see these referred to as “static residential” proxies, and they’re considered a step down from residential proxies. ISP proxies are still owned by internet providers, but they don’t use end users' actual devices. Instead, they’re hosted at data centers. This gives them faster performance and higher uptime, but they’re more likely to be blocked than mobile and residential proxies.
Common use cases:
- SEO monitoring
- Managing multiple e-commerce accounts
- Sneaker copping
Datacenter proxies
This is the cheapest type of proxy server, and you’ll get what you pay for. Web scraping with datacenter proxies is only successful about half the time with popular targets like Google and Amazon, but with their low cost, the downside risk is somewhat minimized. Typically, proxy companies charge by the IP rather than the Gigabit for datacenter proxies, but some offer both options.
Common use cases:
- Large-scale web scraping
Comparison of proxy types for web scraping
| Feature | Mobile | Residential | ISP (Static Residential) | Datacenter |
|---|---|---|---|---|
| Trust level | High (Real mobile users) | High (Real home users) | Medium (Hybrid) | Low (Flagged as servers) |
| Response speed | Slower (150-200ms) | Moderate (100-150ms) | Fast (<50ms) | Fast (<50ms) |
| Best use case | Hardest targets (Social, search) | E-commerce, geotargeting | SEO monitoring | Large-scale web scraping |
| Pricing model | Per GB | Per GB | Per GB or IP | Per IP |
The power of proxy rotation
No matter which type of proxy server you choose, one of the most effective features to look for is the ability to rotate IPs. With each new request you make, a rotating proxy will automatically change the IP address. If one request gets blocked, a rotating proxy will assign a new address until it’s successful. With many companies, you can also configure your setup to change the proxy after a specific period of time. These are typically available with all proxy types except ISP and static residential proxies.
When a proxy server is not a good idea for scraping
Proxy servers are an extremely effective tool for web scraping, but just because you can use them doesn’t necessarily mean you should. Here are some situations you should look out for before you get started:
- Terms of service violations: Using a proxy server alone isn’t against the law, but using one for web scraping in a way that violates a website’s terms of service can open your business up to litigation. Just last year, Reddit filed a lawsuit against the AI search developer Perplexity over the practice. Before you set up your web scraper, look into the site’s terms and conditions and make sure you’re not violating its copyright policy. When in doubt, consult an attorney to ensure you’re in compliance.
- Small-scale tasks: Proxy servers are best suited for web scraping jobs that require thousands of requests. If you only need data from a handful of pages each month, a proxy is probably overkill, and you can likely get the job done with a virtual private network, or VPN.
- Sites with public APIs: Many websites provide their own public Application Programming Interface that allows you to scrape data without using a proxy server. These usually have a rate limit on the number of requests you can make, but businesses with smaller data collection needs can often get by with a public API rather than paying for a costly proxy server data each month.
The bottom line
If your business requires you to do large-scale data collection for market research, you’re probably going to have to utilize a proxy server at some point. And as bot blockers get more sophisticated at detecting web scraping activity, it’s more important than ever to make sure your proxy servers are up to the task. If you’re newer to the proxy space, I’d recommend starting small and experimenting with a cheaper datacenter proxy before investing in more expensive residential and mobile ones.
