Part 1: The Ad Scanning & Compliance Flow
This advanced flow uses browser automation to scan websites for ads, capture screenshots, extract text, and validate compliance using GPT-4.1. Let's break down the key stages.
Stage 1: Setup & Website Crawl
API Input
→
Crawler
→
Browser Open
API Input: Receives target URL, search terms, and compliance instructions
Crawler: Discovers pages on the target website (depth 1, max 1 page for speed)
Browser Open: Opens browser with proxy support (country: IL) for each discovered page
Stage 2: Page Loading & Dynamic Content
Navigate
→
Delay (14s)
→
Scroll (2x)
→
Delay (4s)
Navigate: Goes to target URL in the browser
First Delay (14s): Waits for initial page load and JavaScript execution
Scroll (2x): Scrolls page twice with 500ms between scrolls to trigger lazy-loaded ads
Second Delay (4s): Waits for dynamic content to fully load after scrolling
Why the delays: Modern ad platforms use JavaScript and lazy loading. These delays ensure all ads are visible before we search for them.
Stage 3: Ad Discovery & Element Search
Browser Search Text
→
Array Flatten
→
Iterator
Browser Search Text: Searches page for user-provided search terms (e.g., "sponsored", "ad", brand names)
Configuration:
- • Max 10 results per search
- • Searches up to 3 parent levels (captures entire ad container)
- • Returns element index for each match
Array Flatten + Iterator: Processes each found ad element individually
Stage 4: Screenshot & Text Extraction
For Each Ad Element:
1.Browser Screenshot: Captures visual of the specific ad element
2.Browser Get Text: Extracts all text content from the element
3.S3 Upload: Uploads screenshot to cloud storage, gets permanent URL
Parallel Data Collection:
Per Ad Element:
• screenshot_url: "s3://..."
• text: "Extracted ad copy"
• element_index: 0-9
Stage 5: AI Compliance Validation
★ AI Prompt
Model: GPT-4.1
Input: Instructions + Text
Output: Compliance verdict
Input:
- • User's compliance instructions
- • Extracted ad text
Output:
- •
meet_compliance: "yes" or "no" - •
explain_why: Detailed explanation
Example Prompt:
Following the instructions:
"{instructions}"
Check this ad text:
"{text}"
Return: meet_compliance (yes/no) and explain_why
Example instructions: "Flag any ads claiming '100% guaranteed results', mentioning specific financial returns, or using urgency tactics like 'limited time only'."
Stage 6: Merge & Store Results
Merge Arrays
→
Dataset (Write)
Merge Arrays: Combines 3 data streams into single records:
- • Array 1: Screenshot URLs (from S3 Upload)
- • Array 2: Ad text (from Browser Get Text)
- • Array 3: Compliance results (from AI Prompt)
Dataset Sink: Saves complete ad records to cloud storage
Final Dataset Schema:
{
"screenshot_url": "https://s3.../ad-image.png",
"text": "Extracted ad copy and text",
"meet_compliance": "no",
"compliance_info": "Violates rule X because..."
}
Flow Summary
Input (URL + Rules) → Crawler → Browser Open → Navigate & Wait → Scroll & Load → Search Ads → Iterate → Screenshot + Text + Upload → AI Compliance Check → Merge Data → Store Results
Time: ~2min
Per page scan
Output: 10+ ads
With compliance verdicts

Flagged Ads
How It Works Together:
1. Configure: Enter target URL (e.g., affiliate partner's site), search terms (e.g., "ad", "sponsored", your brand name), and compliance rules
2. Execute: Click "Check ads compliance" to trigger the scan
3. Processing: Flow opens pages, scrolls, searches for ads, captures screenshots, extracts text, and validates compliance
4. Storage: All findings are saved with screenshots and compliance verdicts
5. Review: Image gallery displays flagged ads with:
- • Ad screenshot
- • Snapshot timestamp
- • Compliance status (yes/no)
- • Detailed violation explanation
6. Action: Review violations and take action (contact affiliate, adjust guidelines, etc.)
Example Use Case:
Monitor affiliate partners to ensure they're not making exaggerated claims about your product. Set search terms to your brand name, provide compliance rules like "No income guarantees, no before/after photos without disclaimers", and run daily scans to catch violations early.
