What Are Proxies Used For? 15 Common Proxy Use Cases

Using an IP address different from your own is a good idea for several reasons. From anonymity to complex business use cases, there are plenty of possibilities. One of the solutions is proxies.

Proxy servers give users greater control over internet access, enabling more efficient web scraping, ad verification, price monitoring, and other use cases.

What Is a Proxy Server and Why Do People Use It?

A proxy server acts as an intermediary server for your device, handling your internet connections and routing your web requests.

When you visit a website, your device sends its request to the proxy first. The proxy then connects to the website using its own IP address so your real identity stays hidden. After it receives a response from a website, it returns everything to your device. As a step-by-step process, this is how proxies work:

• You send a request from your device.
• The proxy receives your request.
• The proxy forwards the internet traffic to the destination server using its own IP address instead of your original IP address.
• The web server sends the response back to the proxy.
• The proxy delivers the data to you.

There are two main types of proxies. A forward proxy sits between you and the internet, hiding your outgoing traffic and your identity from the sites you visit.

Meanwhile, reverse proxies sit in front of a web server to manage incoming traffic, and many enterprises deploy reverse proxies to improve network performance and ensure another layer of security, as reverse proxies also protect the internal network. Usually, the goal of a reverse proxy is to distribute network load more evenly while also protecting the internal network from unauthorized access attempts.

This article focuses on forward proxies since they handle the most common personal and business needs.

Business Proxy Use Cases

Web Scraping

Web scraping is automated data gathering from websites and other online sources. Companies and individuals use it for various purposes, including market research, lead generation, price aggregation, and more.

Most websites limit the number of requests from a single IP address. Since proxies replace your IP with their own, they’re the most efficient tool to bypass all IP-based restrictions. With anonymous proxy servers, scrapers can send requests from different IPs in different locations.

Since all these web requests look like they come from genuine visitors accessing web pages, it becomes more difficult for websites to recognize and block the scraping activity.

Collecting AI Training Data

Proxy servers let AI teams collect training data at scale without getting blocked. Machine learning models need massive amounts of web data to generate accurate outputs. Data scientists use proxy networks to scrape millions of documents without getting blocked, allowing them to gather AI training data continuously.

Feeding RAG Systems

Retrieval-Augmented Generation (RAG) systems rely on real-time web data to provide up-to-date answers. Developers use proxies to fetch this live information continuously without target websites throttling their automated requests.

AI Agents Browsing the Web

AI agents navigate the internet to accomplish complex tasks like booking flights or scheduling appointments. Developers route the agent’s traffic through proxies so websites view the automated activity as authentic human browsing.

SEO Monitoring

Search engine optimization is crucial for most modern businesses, regardless of their size. Only 0.63% of people visit the second page of Google search results. So, it’s no surprise that SEO monitoring recently became one of the most significant proxy use cases.

A high rank in search engine results brings organic traffic and new clients. More importantly, it builds long-term brand awareness and increases revenue. To maintain this rank, businesses must check search engine result pages (SERPs) regularly and keep an eye on rival websites.

Proxy servers allow anyone to replicate searches and send web requests with different IP addresses from different locations. This practice provides valuable SEO performance insights. By analyzing this data, businesses can modify their SEO strategy as necessary to ensure they’re where their clients are.

Ad Verification

Companies spend a lot of money on ads, but sometimes those ads don’t show up correctly or are misrepresented. Businesses can use a proxy server to verify that their ads display as intended. By changing IP addresses, they can look at their ads from different cities to ensure functionality and legitimacy.

It helps businesses ensure ads are placed in suitable environments and in the right geography, preventing wasted budget and brand damage from ad fraud.

Brand Protection

Counterfeiters often try to sell fake products under a famous brand name. Companies use proxies to scan the web anonymously and identify websites committing fraud. Once they find bad actors stealing their intellectual property, they can issue legal takedown notices to protect their customers.

Price Intelligence

Stores change their prices all the time based on who’s looking and from where. A proxy server lets a business see the prices people in other countries are paying. They send web requests from multiple locations to compare costs, helping them set their own prices to stay competitive.

Market Research

Global companies analyze consumer sentiment and track competitors by gathering data from international forums and regional stores. Proxies allow analysts to view the web from the perspective of a local user, ensuring their research reflects authentic regional conditions.

Travel Fare Aggregation

Airlines and hotels constantly adjust prices based on a visitor’s location and search history. Travel aggregators use proxies to check booking sites from multiple international locations simultaneously, helping them bypass regional price discrimination and find the lowest fares.

Security Testing

Cybersecurity professionals conduct penetration tests to see how corporate firewalls respond to attacks. Traffic routed through proxy networks lets ethical hackers obscure their origins while probing secure sockets layer and TLS configurations for weaknesses. This helps administrators find vulnerabilities before a genuine breach occurs.

Website QA and Localization Testing

Developers must verify that their websites display the correct language, currency, and privacy settings for international users. Teams use proxies to simulate traffic from specific countries, ensuring the site functions perfectly for a localized audience.

Social Media Management

Managing multiple accounts on a single site can be challenging. Social media sites might block access if they see too many accounts on one user’s IP address. A proxy server gives each account its own unique identity, which allows managers to post and chat from different accounts without getting banned.

Personal Proxy Use Cases

Accessing Localized Content

Many websites and online services are only available to visitors from a specific country. Authorities, institutions, and ISPs can censor certain websites, like search engines, social media platforms, and more. While there are usually legitimate reasons behind geo-blocking (copyright and licensing limitations), it’s often prone to abuse.

Residential proxies offer the easiest way to get around these limitations. It’s as simple as getting an IP address in the correct location. By employing a proxy from a country where the content is available, businesses and individuals can mask their internet usage to access it safely and privately.

Online Privacy

Online tracking has become a growing concern in recent years. The reason behind this trend is obvious. Ghostery’s WhoTracks.Me data shows Google trackers on 7,534 of the world’s top 10,000 websites, with trackers present on ~41% of traffic to those sites overall.

With so many companies trying to get user data, maintaining online anonymity has become one of the most common proxy use cases. Businesses, NGOs, researchers, journalists, and others can access the internet anonymously with proxies. As the proxy handles all traffic, it also takes on the burden of tracking, keeping the user’s internet usage private and untraceable.

Not All Proxies Are the Same

A residential proxy routes your traffic through genuine home devices tied to official internet service providers. Because websites see a legitimate household connection, these IPs receive much lower block rates. However, they cost more than their alternatives.

Datacenter proxies get their IP addresses from servers rather than consumer ISPs. They offer incredible speeds and are suitable for tasks that don’t trigger automation restrictions. Most security systems can easily identify their non-residential origins and frequently ban the entire subnet if they detect suspicious activity.

ISP proxies combine the best of both worlds by hosting residential IPs on datacenter infrastructure. This setup provides the legitimacy of a home connection with the speed and stability of a business-owned server. They are great for managing sensitive commercial accounts, though their IP pools are smaller than standard residential networks.

Mobile proxies route your requests through cellular networks, offering the highest level of trust available. Because mobile carriers cycle a limited number of IPs among millions of users, websites rarely block them, avoiding accidental bans of real mobile customers.

Beyond infrastructure, proxies are also categorized by how much information they hide:

• Transparent proxy. A transparent proxy forwards your real IP address but identifies itself as a proxy, often used by organizations for content filtering and to cache data without altering the client’s request.
• Distorting proxy. A distorting proxy identifies itself as a proxy but passes a fake IP address to the website.
• Anonymous proxy. An anonymous proxy hides your real IP address but still admits it is a proxy.
• High anonymity proxy. Hides both your IP address and the fact that you are using a proxy.

Additionally, tasks require different setups. Some users need private proxies for exclusive access, while complex scraping tasks often demand a rotating proxy to assign a fresh IP for every new connection, unlike a shared proxy or public proxy, which might be too slow.

A public proxy is available to anyone, and while a shared proxy splits costs among multiple users, both handle numerous web requests poorly compared to dedicated solutions.

Using the first proxy you come across is far from a good idea, however. There are countless free proxies online, but they have a much greater degree of risk.

After all, you’re trusting an unknown entity with your most sensitive data. Besides, not all proxies are fit for all purposes. If you’re looking for a hassle-free experience without compromise, make sure you do your research and select a proxy provider with a good reputation that has been involved in the market for years.

Which Proxy Type Is Best for Each Use Case?

Proxies vs VPNs: What’s the Difference?

Both tools help with masking IP addresses, but they work in different ways. A proxy server usually only works for one app, like your web browser. It’s great for tasks like web scraping because it’s fast. A VPN covers your whole device, establishes a secure private network, and encrypts all your network traffic.

If you just need to change your IP address for a specific task, a proxy server is usually better. Proxies don’t slow down your traffic as much as virtual private networks do.

However, a VPN is better if you want to lock down every bit of data on your device. Most people use an anonymous proxy for business tasks and a VPN for personal safety.

Are Proxies Legal and Safe To Use?

Using a proxy server is perfectly legal in most parts of the world. It’s a neutral tool that’s only as good as your intentions are. You can use it for good things, like protecting your data or market research. Problems only start if someone uses an anonymous proxy to break the law, commit fraud, or partake in some other questionable activities.

Safety also depends on whom you’re getting the proxy server from. Good providers make sure their web proxies are clean and fast, and they don’t peek at your web traffic or sell your info. Using a trusted proxy server is a safe way to browse and do business.
