Private vs. Shared Proxies: Which Should You Choose?

Private and shared proxies look similar on the surface — same protocols, same network, same control panel. The difference is who else is using the IP. A private proxy is assigned to one customer. A shared proxy is used by several customers at once. That single distinction drives the price gap, the performance characteristics, and which workloads each is actually right for.

The price difference is real and meaningful

Shared proxies cost roughly a third of comparable private plans. EZProxies USA shared starts at $0.65 per IP per month at the 500-pack level; USA private starts at $1.20 per IP per month at the same scale. For a 500-IP setup that is a $275/month difference — significant if you are running on a thin margin, irrelevant if each proxy generates value worth far more than its cost.

The price difference reflects the underlying economics. A private IP can only be sold to one customer; a shared IP is sold to several. Providers recover their cost faster on shared, which lets them charge less per slot.

Performance is the same; reputation is not

Both plan types run on the same network in the same datacenters. Raw speed, latency, and uptime are equivalent — you are not getting a slower IP by going shared. What you are getting is an IP whose recent history includes whatever other customers on the shared plan have done with it.

If your neighbor on a shared plan ran a heavy scraping operation against a particular site yesterday, that site may rate-limit or challenge your traffic from the same IP today — even if your traffic is perfectly polite. The IP reputation carries.

On private plans the IP is exclusively yours, so its reputation reflects only your behavior. The clean-slate effect matters more on targets that fingerprint and score IPs aggressively (account platforms, ticketing, some e-commerce). It matters less on targets that just care about request rate (most public-data sites, news, directories).

When private wins

• Account management. Every multi-account workflow needs one dedicated IP per account. Sharing IPs across accounts defeats the purpose. See account management for the full set of considerations.
• Ticketing, sneakers, drops. Anything where each session needs a clean IP that has not been seen recently. Shared IPs almost always carry burnt history from prior buyers.
• Ad verification and brand safety audits. You want to sample what real users see; a noisy shared IP gets challenged or served fallback content that distorts the data. More on ad verification.
• Workloads on aggressive anti-bot sites. Cloudflare-protected sites, DataDome targets, anything that scores IP reputation. Shared IP reputation here is often already burned.

When shared is the right answer

• Bulk SEO and SERP monitoring. Tracking thousands of keywords across many targets — volume matters more than per-IP cleanliness. SEO monitoring often runs on a mix of shared (for breadth) and private (for trust-sensitive client work).
• Link verification and crawler health checks. Mostly read-only, low intensity per request, tolerant of occasional retries.
• Public-data scraping at scale. Government data, news aggregators, directory sites, large catalog crawls where the per-IP cost matters more than IP perfection. See web scraping.
• Cost-sensitive bootstrapping. When you are still validating whether a scraping or monitoring approach works, starting on shared lets you run the experiment at a fraction of the cost. Move to private when the workload graduates.

How to decide in practice

The framework is simpler than the marketing makes it sound:

1. Does your target site care about IP reputation? If yes — account-based platforms, sites with serious anti-bot defenses — pick private. If no, shared works.
2. How much does each successful request matter? If a single blocked request breaks a critical workflow (a checkout, an account creation), pick private. If a 5% failure rate is fine and you just retry, shared works.
3. What is the cost of being wrong? If a burnt IP would cost you a banned account or a legal review, the IP-cost premium for private is rounding error. If it just means an extra retry, shared.

Can you switch later?

Yes. Contact support any time and we will move you between plans and credit the unused portion of the old subscription. Many customers start on shared to validate a workload then move parts of it to private as it grows. Some run permanently on a mix — shared for breadth, private for the segments that demand clean IPs.
