Rank tracking that matches what US searchers actually see

Why Google SERP data is a US-local problem

Google has built its entire US ranking stack on the assumption that a searcher's physical location, carrier, time of day, and prior query history shape what they should see. "Rank 3 nationally" is not a real number; "rank 3 for [hvac repair] in the Chicago DMA on a Thursday evening from a Comcast IP" is. Any US SEO pipeline that collapses those dimensions into a single national number is reporting fiction to its clients.

Google Local Pack, introduced in its current form in 2015 and tuned heavily through 2024's HCU updates, is particularly location-sensitive. Local Pack results for [hvac repair] in Chicago DMA (602) pull from the Google Business Profile pool in that DMA's address list, not from the national index. You cannot audit that from a datacenter IP in Ashburn — Google will either suppress the Pack or serve it relative to the exit's actual location, which isn't the location you care about.

The sampling plan US SEO actually needs

For a US rank-tracking or visibility pipeline to produce numbers a search strategist can bet on:

• DMA targeting. At minimum. Nielsen DMA is the right unit of granularity for Local Pack and Google Ads "location" — coarser than ZIP, finer than state. Proxaro exits on all 210 DMAs.
• Carrier diversity. Google rate-limits per-subnet aggressively. Running a 10k-keyword pipeline through a single Spectrum /22 for three hours will start serving sorry-interstitials. Rotate across Comcast / Spectrum / AT&T / Cox allocations.
• One query per IP per window. Google's rate model is built around "a user does a few queries per hour." Respect that — the network will keep serving you for years. Burn through at scraper volume from a single pool and you'll watch your block rate climb.
• Predictable pacing. A SERP tracker that fires 10k queries in 60 seconds from a residential pool looks nothing like a real user. Pace the pipeline over the hour.

How Proxaro fits SERP work

US residential, DMA-targeted

Use for Local Pack monitoring, Maps pack audits, and any location- sensitive SERP feature (featured snippets with local bias, "near me" handling). Our gateway accepts X-PX-Dma: 602 — the three-digit Nielsen code — and routes you to a residential exit from a Chicago- allocated IP on a major carrier.

US ISP, daily baseline

Static US ISP IPs on Comcast and Spectrum are the right tool for daily baseline rank checks — you want the same IP returning day after day so Google's personalization drift is a constant, not a variable. Pair with a clean accept-language and no cookies.

Scale math

A 5,000-keyword-per-day US tracker across 10 DMAs pulled once daily is ~50k requests per day. Average SERP HTML is 70 KB for top-20, so ~3.5 GB/day or ~100 GB/month. That's a Coast Plus workload, with ISP allocation for the baseline pulls and residential for the DMA pulls.

A 500-keyword local SEO tracker across 30 cities pulled weekly is ~15k requests a week, ~500 MB/week. Local covers this comfortably.

What we will not do

• We won't help scrape Google Search Console for an account you don't own — that's a TOS violation and a hard line for us.
• We apply per-account rate caps on Google queries. Abusing them surfaces on our monitoring and the account gets paused before we take down capacity for the rest of the customers.
• We won't sell proxies bundled with "SERP scraping SaaS that bypasses Google's rate limits." That's a product category that doesn't age well and we don't want to be part of it.
