Location-Aware SERP Tracking
With Residential Proxies

Monitor search rankings, competitor visibility, and organic-search changes using currently available residential locations. Always follow search-engine terms and keep automated requests within permitted limits.

Compare Location-Aware Search Results

Search results can vary by location, device, language, and account state. Residential endpoints help you compare location-dependent results as part of a controlled SEO workflow.

City-Level Targeting

Choose country, state, city, ZIP code, and ASN options from current inventory for localized checks. Compare results with consistent language, device, and account settings.

Repeatable Rank Checks

Keep location and session settings consistent when comparing keyword results over time.

Controlled Request Routing

Route permitted checks through selected endpoints and configure request rates within each destination's published rules.

Collect Point-in-Time Ranking Observations

Compare snippets, local packs, and organic results from available locations. Results also depend on language, device, cookies, and account state. Choose timed rotation in whole-minute intervals from 1 to 120 minutes, or sticky mode with no scheduled rotation. A sticky IP can still change if its residential peer disconnects or the targeting changes.

Install Puppeteer with npm install puppeteer. For this browser example, select an HTTP-capable endpoint and set PREPROX_PROXY_HOST, PREPROX_PROXY_PORT, PREPROX_PROXY_USERNAME, and PREPROX_PROXY_PASSWORD from the dashboard. Copy the complete generated username and password without removing targeting parameters. Set TARGET_URL to a permitted URL; the default checks https://example.com/.

  • Rotating and sticky session options
  • Country, state, city, ZIP code, and ASN options where available
  • HTTP/S and SOCKS5 connection support
  • Standard proxy authentication for compatible tools

COMMON QUESTIONS

SERP Tracking FAQ

Why can't I just use a VPN for SEO ranking checks?

VPN and proxy services offer different location and session controls. A residential endpoint can support checks from available locations, but neither service guarantees accurate rankings, access, or an identical result for every user.

Does PreProx support mobile useragent tracking?

You can pair a residential endpoint with a mobile user agent in a compatible tool. Search results can still vary based on language, cookies, account state, and the search engine's own systems.

Can I run recurring rank checks with these proxies?

Yes, provided your requests follow the destination service's rules and your tool handles timeouts, retries, and changing network conditions. PreProx does not promise uninterrupted availability.
