How much does it cost to track a keyword?

Top 100 in one realtime call: 7 credits. The same request in the batch lane (POST /v1/batches): 3.5 credits. Top 10 only: 1 credit (0.5 in batch).

How fast is the batch lane?

Batch jobs are processed within about 15 minutes. POST /v1/batches returns 202 with a batch id per request; poll GET /v1/batches/{id} or receive a signed batch.completed webhook.

Can I track mobile rankings?

Yes, pass device=mobile. Desktop is the default.

How do I track local rankings?

Pass location ("Denver, Colorado, United States") or a uule string. country sets the country.

Why resolved URLs matter?

Google started wrapping result links in /goto redirects in 2026, which broke naive rank trackers. SerpKite always returns the destination URL and a canonical domain.

Is there a dedicated rank endpoint?

Yes. POST /v1/rank with q and domain returns that domain's position (or null) and its matching URLs in the top N, priced like the equivalent /v1/search depth. Use /v1/search when you want the full top 100 as in the example.

Google Rank Tracker API

Find where a domain ranks in Google's top 100 for any keyword, country, city and device. num=100 returns all 100 positions in one call for 7 credits, and the batch lane halves that for overnight tracking jobs.

Overview

What the Google Rank Tracker API does

Rank tracking is built on /v1/search. Since Google removed num=100 from its own URLs, getting the top 100 means ten page requests. SerpKite does that for you and bills it as a depth bundle: 7 credits instead of 10.

Positions are only useful if you can match them. Every result carries the resolved destination link (no /goto or /url?q= redirects) and a canonical domain without www., so matching your site is a string comparison. If you only need one domain's position, POST /v1/rank returns just that. For scheduled jobs, POST /v1/batches queues requests at half price and delivers each result to your webhook.

What you get

results[].position integer: 1-based organic position across all 100 results.
results[].link string: Resolved destination URL, never a Google redirect.
results[].domain string: Canonical host without www., for exact matching.
places[] / top_stories[] array: SERP features that push organic results down, when present.
meta object: request_id, credits_used, cached, engine, latency_ms, resolved_urls and parse_quality. parse_quality=empty means the call was not billed.

Find a domain's position

Top 100 in one call, matched by domain

Request num=100, project only the three fields you need, and scan for your domain. Because domain is canonical (no www.) and link is the real destination, there's no redirect decoding or URL normalizing on your side.

Overnight jobs: the batch lane

Send up to 100 queries to POST /v1/batches and they are queued at half price. You get 202 with a batch id per query right away; the finished result is posted to your webhook_url, signed with X-SerpKite-Signature (HMAC-SHA256 of <timestamp>.<body>), or you poll GET /v1/batches/{id}. Results are kept for 24 hours.
