Why is my rank tracker showing different positions than what I see in my browser?

Because you're measuring from different locations, devices and login states. Your browser is logged in and personalized from your office IP; the tracker queries from somewhere else. Neither is the generic local SERP unless it uses a target-location IP, logged out, with pws=0.

Can I just add the city name to my search instead of using a proxy?

No. Searching dentist São Paulo from a foreign IP doesn't reproduce the Local Pack, organic order or SERP features a local user sees. Google weighs the connecting IP heavily, especially on desktop. You need a local IP plus the uule parameter, not a modified keyword.

Do I need a mobile proxy for SEO, or is residential enough?

Residential works for national-level rank tracking. For local SEO in Brazil and Spain, mobile carrier IPs are more accurate because they match the mobile-first indexing context, carry the highest Google trust, and reflect how most searches actually happen in those markets.

Why are datacenter proxies bad for Google rank tracking?

Google identifies datacenter ASN ranges and responds with CAPTCHAs, throttling, or a less localized SERP. The data still loads, but it's systematically biased, so your rankings look measured when they're actually wrong.

What is the uule parameter and why does it matter?

uule is a base64-encoded string that tells Google to simulate a search from a specific location, down to a city or neighborhood. It's the most powerful parameter for local SEO because it pins the exact location even when your proxy is country-level. Pair it with a matching carrier IP for the most accurate local SERP.

Should I track mobile or desktop SERPs?

Both ideally, but if you track one, match your audience. Mobile is the primary signal under mobile-first indexing, and in Brazil and Spain mobile search share is above the global average, so mobile is usually the more important view.

How do gl, hl and pws work together?

gl sets the country result set (gl=br, gl=es), hl sets the interface and influences result language (hl=pt-BR, hl=es), and pws=0 disables personalization. Use all three together, and keep them consistent with your proxy's country, for clean, reproducible rank data.

Can I track Local Pack rankings from another country?

Not meaningfully. The Local Pack is driven by proximity to the searcher's location, calculated from IP on desktop and device location on mobile. You need a local IP in the target market, and uule encoding for the specific neighborhood, to get real Local Pack data.

How do I track AI Overviews?

Use the same geo-accurate setup as rank tracking, a target-location carrier IP with the right gl/hl, then record whether an AI Overview appears, whether your brand is cited, and which sources it pulls from. AI Overview content varies by location and language, so a Brazilian and a Spanish query return different overviews.

Will one proxy IP work for tracking multiple cities?

A single country-level IP plus different uule strings can approximate multiple cities, but for the most accurate Local Pack data, agencies assign one dedicated sticky carrier IP per target city or region and hold it stable for comparable day-over-day tracking.

How often can I query Google without getting blocked?

There's no fixed number, but pace queries like a human and spread load across stable IPs rather than bursting from one. Sudden high-volume querying from a single address triggers CAPTCHAs and biased SERPs. Clean carrier IPs plus sane pacing keep results accurate.

Is using proxies for SEO rank tracking against Google's terms?

Automated querying of Google can conflict with its terms of service, and you should review them and applicable law for your use case. Many SEO tools query Google programmatically; the responsible approach is reasonable volume, logged-out de-personalized queries, and respect for the platform.
