Residential from $0.80/GB · city targeting in 200+ countries · SERP API as the no-proxy option
SEO proxies are IPs in the exact country and city you rank for, so a rank tracker, a SERP scraper or a crawler sees the results a local searcher sees instead of results shaped by your office location. Quantum Proxies provides rotating residential IPs from $0.80/GB with city targeting in 200+ countries, datacenter lines from $0.50/GB for crawlers, and a SERP API that returns Google results as JSON.
Search engines personalise and localise. The same query returns a different top ten in Austin and in Boston, a different local pack for each neighbourhood, and different ads, shopping units and AI overviews by country and language. A team that tracks rankings, audits SERP features, researches keywords or checks competitors therefore needs to ask the engine from where its audience is, and to ask many times a day without a single address being throttled.
SEO proxies are the IPs that make this possible: rotating residential addresses with country and city targeting for search result pages, and fast datacenter lines for crawling sites, checking backlinks and rendering pages for technical audits. Quantum Proxies sells both pay as you go, and adds a SERP API for teams that want the results as JSON and no proxy handling at all.
Search engines weigh the location of the requesting IP heavily. Location parameters in the query URL help, but a request from a datacenter in one state carrying a city parameter for another is a contradiction the engine may resolve either way, and the results you store are then neither city's. For local rankings, map packs and 'near me' queries, the IP has to be in the city, or at least the region, you report on, and the language and country codes have to agree with it.
Residential Basic offers city targeting across 200+ countries and ASN targeting; Residential Premium adds state and ISP selection; mobile IPs add region and carrier for mobile-first SERPs. The location goes in the proxy username, so a tracker can loop over fifty cities with one credential and one line of configuration per city.
Rank tracking is a volume job: keywords times locations times devices times daily checks. Each result page should come from a different IP so no address accumulates a search pattern the engine treats as automated, which is exactly what per-request rotation on Residential Basic and Premium does. Residential Premium also allows unlimited concurrent connections, so the tracker's parallelism is set by your own politeness settings rather than by the proxy.
On bandwidth, a Google results page is heavier than a plain article page, so the 60 KB rule of thumb understates it; fetch the HTML only, skip images and scripts, and measure a sample before sizing the plan. Residential Basic runs $1.00 per GB on 25 GB down to $0.80 at 1,000 GB, valid 90–360 days, with no subscription.
Not all SEO traffic goes to Google. Site crawls for technical audits, competitor site structure checks, backlink verification, broken link scans, log-file enrichment and page speed tests hit ordinary websites that rarely block automation. For that traffic a datacenter proxy is faster and cheaper: 1 Gbps+ lines, rotating or dedicated IPs, country, state and city targeting in 100+ countries, from $0.80 per GB on 50 GB to $0.50 per GB at 500 GB.
Dedicated datacenter IPs are also convenient for crawling your own or clients' sites, since a fixed address can be whitelisted in the firewall or excluded from analytics. Keep the split simple: residential for anything that returns a search result page, datacenter for everything else, and route both through the same proxy configuration in the tool.
If the deliverable is a rankings table rather than a proxy integration, the SERP API at /serp-api is the shorter path. You send a query and a location; it returns Google results as JSON, and you never render a results page, rotate IPs or handle a captcha. It runs on the same residential network described above and bills from the same wallet, so it can sit next to raw proxies in one account and one budget.
Typical uses: daily keyword rank checks across a list of cities, SERP feature monitoring, competitor visibility reports, keyword research from live results, and feeding results to an LLM. For teams on Claude or Cursor, the MCP server at /mcp-server exposes the same search as a tool the model can call directly.
Because every product is a standard HTTP/HTTPS or SOCKS5 proxy with user:pass authentication or IP whitelisting, no integration is specific to us. Self-hosted rank trackers take a proxy list or a gateway URL in their settings; desktop crawlers of the Screaming Frog kind accept a proxy host, port and credentials in their configuration; browser-based audits in Playwright or Puppeteer take the proxy as a launch option; a Python or Node script passes it to the HTTP client.
Generate one credential per tool in the dashboard so usage is visible per tool, encode the country, city and session type in the username, and whitelist the tool server's IP if you prefer not to store a password. The same credentials work across rotating residential, datacenter, ISP and mobile products alike.
Everything is pay as you go from a wallet you top up from $5 by card, PayPal or 300+ cryptocurrencies with no KYC; the balance never expires and there is no subscription. Residential Basic starts at 25 GB for $25 and reaches $0.80 per GB at 1,000 GB; datacenter starts at 50 GB for $40 and reaches $0.50 per GB at 500 GB; ISP proxies, for a tool that must keep one fixed IP, are $3.80 per IP per month.
New accounts get 100 MB of Residential Basic free for 5 days, unlocked by a one-time SMS verification and with no card, which is enough to run a rank tracker against a few hundred result pages and confirm the geo targeting before buying. Support is 24/7, and the dashboard and REST API expose usage per credential.

| Daily keyword rank tracking by country | SERP API or Residential Basic | Rotating, country-targeted | Results as JSON with no proxy handling, or a fresh residential IP per query from $0.80/GB |
| Local rankings, map pack, 'near me' queries | Residential Basic (city targeting) | Rotating, city-targeted | The IP is in the city you report on, so the local pack matches what residents see |
| Mobile SERPs | Mobile 4G/5G | Rotating, region and carrier targeted | Real carrier IPs return the mobile result set; from $2.30/GB at 500 GB |
| Site crawl for a technical audit | Datacenter | Rotating or dedicated IP | 1 Gbps+ lines and $0.50/GB at 500 GB; ordinary sites rarely block it |
| Backlink and competitor site checks | Datacenter | Rotating | Many small fetches on non-search targets at the lowest per-GB price |
| Tool that must keep one fixed IP for whitelisting | ISP / static residential | Fixed IP, unmetered | Same address every day, $3.80 per IP per month |

SEO proxies are IP addresses in the country and city you want rankings for, used by rank trackers, SERP scrapers and crawlers so that each request looks like a local user rather than an office or a datacenter. Rotating residential IPs handle search result pages; datacenter IPs handle site crawls and backlink checks. Both are standard HTTP/SOCKS5 proxies.
Rotating residential with city targeting. Search engines localise by the requesting IP, so a Residential Basic session pinned to the target city returns the result page a resident sees, and per-request rotation keeps any single IP from building an automated-looking pattern. It costs from $0.80 per GB. Use datacenter proxies only for non-search targets such as site crawls.
Yes. Residential Basic supports city targeting in 200+ countries: put the country and city in the proxy username and the request leaves from an IP there. Residential Premium adds state and ISP selection, and mobile IPs add region and carrier for mobile SERPs. A tracker can loop over a list of cities with a single credential.
Use the SERP API at /serp-api when you want Google results as JSON for a query and location without rendering pages, rotating IPs or handling captchas. Use raw residential proxies when your tool already scrapes SERPs itself, needs a non-Google engine, or must fetch the full HTML. Both bill from the same wallet, so mixing them is normal.
Yes. Every Quantum Proxies product is a standard HTTP/HTTPS or SOCKS5 proxy with user:pass authentication or IP whitelisting, so it goes into any tool that accepts a proxy: self-hosted rank trackers, desktop crawlers, headless browsers, Python or Node scripts. Country, city and session type are set in the username, so no tool-specific integration is needed.
More than a plain page: a Google results page is heavier than the 60 KB rule of thumb for an HTML article, so fetch HTML only and measure a sample of your own queries before choosing a plan. Residential Basic costs $1.00 per GB on the 25 GB plan and $0.80 per GB at 1,000 GB, valid 90–360 days, and the 100 MB free trial lets you measure first.
Yes. New accounts get 100 MB of Residential Basic traffic free for 5 days, one per person, unlocked by a one-time SMS verification in Settings → Free Trial, with no card. That covers a few hundred result pages, enough to point a rank tracker at a handful of cities and confirm the geo targeting before buying bandwidth.
Skip the marketing. QuantumProxies.io publishes a machine-readable site map, Markdown for every page, a free MCP server, and APIs billed from the same balance as your proxies.
