How to Spy on a Domain — RankSpy Setup Guide
Fingerprint any domain in 12-20 seconds with RankSpy. Get performance, AI search readiness, tech stack, ads, social, backlinks, keywords, and on-page audit
---
Introduction
RankSpy is the competitor intelligence module inside Rankar.ai's Agency Dashboard. Unlike older competitor tools that require building elaborate keyword lists or seeding backlink data, RankSpy works as a one-shot fingerprint: enter any domain, get an 8-tab report covering performance, AI readiness, tech stack, ads, social, backlinks, keywords, and on-page details. This guide walks through the first scan using https://rankar.ai as the demo URL.
Step 1: Open Rank Spy From the Sidebar
In the sidebar under CORE SEO, click Rank Spy. The URL becomes /agency-dashboard/rank-spy. The empty state shows a single input field and a Spy on site button. The tagline reads "Competitor intelligence — fingerprint any domain in seconds."
Step 2: Enter a Domain
Enter rankar.ai (or any competitor domain). RankSpy accepts bare domains or full URLs.
The empty state shows the help text: "Free crawl: tech, ads, social, on-page · Keywords / backlinks / ad creatives load on demand." This tells you which data is included by default and which costs additional credits if you drill deeper.
Step 3: Click "Spy on Site"
Click the Spy on site button. RankSpy shows a Scanning… loader with the message "Scanning rankar.ai — Crawling homepage, robots.txt, sitemap, sub-pages, plus Core Web Vitals. Usually 12-20 seconds."
The scan covers 8 things in parallel: page render + Lighthouse, robots.txt analysis, sitemap parse, AI engine probes, technology fingerprinting, ad pixel detection, social signal sniff, and on-page tag audit.
Step 4: Read the 4 Top-Line KPI Tiles
When the scan completes, the dashboard renders four headline tiles:
- PERFORMANCE — Lab Lighthouse score. For rankar.ai: 76.
- AI SEARCH READY — AI readiness score with letter grade. For rankar.ai: 69 (Grade C).
- TECHNOLOGIES — Count of fingerprinted technologies. For rankar.ai: 1.
- AD PLATFORMS — Number of ad pixels detected. For rankar.ai: 0 (no ad pixels).
Beneath the tiles: BUSINESS MODEL: Mixed / unclear · inferred from tech — RankSpy attempts to classify the business model from the detected tech.
Step 5: Switch Between the 8 Tabs
The tab row across the top:
- Overview — KPIs + Core Web Vitals + tech stack summary.
- Keywords — what the domain ranks for (loads on demand).
- AI Search — AI visibility probe across multiple engines.
- Tech Stack — full technology fingerprint.
- Ads — ad platforms detected + ad creatives (on demand).
- Social — social platform presence and signal volume.
- Backlinks — backlink profile (on demand).
- On-Page — homepage on-page audit.
Each tab is independent and can be opened without affecting others.
Step 6: The Core Web Vitals Section
Below the KPI tiles: a Core Web Vitals panel labelled "Where you can out-perform them on speed." For rankar.ai:
- Performance: 76.
- LCP: 3.96s (target: Good ≤ 2.5s).
- CLS: 0.1349 (target: Good ≤ 0.1).
- INP: 35ms (target: Good ≤ 200ms).
The data source: "Lab data (Lighthouse)" + "Page weight: 596 KB."
Two of three CWV metrics are in the red — exactly the kind of opening you would exploit if you wanted to outrank rankar.ai on a speed-sensitive query.
Step 7: Use the Re-scan Button
The header includes a Re-scan button to refresh the data. Most fields update on every scan; some (keywords, backlinks) only update when explicitly triggered.

Apply This With the Rankar Toolkit
RankSpy works best paired with the rest of the Rankar suite. Spin up the relevant tools: RankTalk • RankOps • RankAudit • RankWriter • RankTracker • RankAIO • RankBridge • RankLinks • RankLocal • RankLaunch • RankSpy • RankUX • RankLead. Each module shares data with the others — fewer tabs, one source of truth.
