Stop Guessing Your Competitor’s Strategy. Just Download It.

Why spend thousands on A/B testing when your competitors have already done it for you?

In the world of paid ads, creativity is expensive. Testing is expensive.

But do you know what’s free? Looking at what is working for everyone else.

Meta (Facebook/Instagram) and Google maintain public “Ad Libraries” for transparency. Most marketers know this. But clicking through a web interface is slow and manual.

The smart way to do competitor research is to scrape it.

If you can download every ad your top 5 competitors have run in the last 6 months, you can see:

1. Which hooks they use.

2. Which creatives they keep running (winners).

3. Which ads they turned off after 2 days (losers).

Here is how to automate this using JavaScript and SociaVault.

The “Ad Spy” Script

We are going to build a script that monitors a competitor’s Facebook Page and alerts us when they launch new ads.

Prerequisites
You’ll need a SociaVault API Key. You can get it here

SociaVault - Social Media Scraping API for 25+ Platforms

The Code (Node.js)

const axios = require('axios');

const API_KEY = 'YOUR_SOCIAVAULT_KEY';
const COMPETITOR_PAGE_ID = '123456789'; // Find this on their FB page

async function spyOnCompetitor() {
  console.log(`🕵️ Spying on Page ID: ${COMPETITOR_PAGE_ID}...`);

  try {
    const response = await axios.get('https://api.sociavault.com/v1/scrape/facebook/ads', {
      headers: { 'x-api-key': API_KEY },
      params: {
        page_id: COMPETITOR_PAGE_ID,
        country: 'US',
        active_status: 'active' // Only show ads currently running
      }
    });

    const ads = response.data.data.ads;
    console.log(`✅ Found ${ads.length} active ads.`);

    // Analyze the ads
    ads.forEach((ad, index) => {
      console.log(`\n--- Ad #${index + 1} ---`);
      console.log(`Started: ${ad.startDate}`);
      console.log(`Platforms: ${ad.platforms.join(', ')}`);
      console.log(`Copy: ${ad.adBody.substring(0, 50)}...`); // First 50 chars
      console.log(`Creative URL: ${ad.image_url || ad.video_url}`);
    });

  } catch (error) {
    console.error("Failed to fetch ads:", error.message);
  }
}

spyOnCompetitor();

Once you have this data, don’t just copy it. Analyse it.

1. Longevity: If an ad has been active for >30 days, it is profitable. Study that creativity.

2. Platform Mix: Are they spending heavily on Instagram Reels but ignoring Facebook Feed? That tells you where their audience is.

3. Copy Patterns: Are they using long-form storytelling or short, punchy hooks?
