ChatGPT, Gemini, Perplexity 및 Claude에서 브랜드 가시성을 추적하는 방법 (코드 포함)

AI search engines like ChatGPT, Gemini, Perplexity, and Claude are
changing how people discover brands. Instead of clicking through
Google results, users now ask AI — and the AI picks who to mention.

The question is: is your brand being mentioned?

Most tools to answer are built for marketers, not developers. So I built webscore-sdk — an npm package that lets you measure this programmatically.

What is GEO?

GEO (Generative Engine Optimization) is the practice of improving
your brand’s visibility in AI-generated answers. Think of it like
SEO, but instead of ranking on Google, you’re trying to get mentioned
when someone asks ChatGPT “what’s the best tool for X?”

Two key metrics matter:

• Mention rate — % of relevant prompts where your brand appears
• Citation rate — % of prompts where your website is linked

Install

npm install webscore-sdk

Enter fullscreen mode Exit fullscreen mode

Quickstart

import { WebScore } from 'webscore-sdk'

const client = new WebScore('your_api_key')

const result = await client.geo.scan('https://yoursite.com')

console.log(result.mentionRate)  // e.g. 67
console.log(result.citationRate) // e.g. 42
console.log(result.sentiment)    // "positive"
console.log(result.score)        // 0–100 GEO score

Free Tier

The free plan includes 10 GEO scans to try it out — no credit
card required. Paid plans with higher limits are coming soon.

Would love feedback on the prompt methodology or the
mention/citation split. Drop a comment below!
