BREAKING IMPROVEMENTS:
1. Early Detection for No Reviews:
- Check for "no reviews" messages in 11+ languages before scraping
- Detect disabled reviews tabs and aria-labels with 0 reviews
- Return early with success when no reviews exist (saves time)
- Prevents wasted scraping attempts on businesses with no reviews
2. Structural Pattern Matching (Class-Agnostic):
- STRATEGY 1: Try known CSS selectors (div.jftiEf.fontBodyMedium, etc.)
- STRATEGY 2: Structural matching - find containers with review-like structure
* Looks for elements containing: author + rating + text + date
* Counts elements with 3+ review indicators (robust, works across layouts)
- STRATEGY 3: Use role="article" with review content detection
- Falls back through strategies automatically
3. Less Script-Dependent Selectors:
- Uses aria-label attributes (more stable than CSS classes)
- Uses role attributes (semantic HTML)
- Searches for structural patterns (author img + rating span + text span)
- Works across different Google Maps page layouts and languages
4. Frontend Improvement:
- Hide "Open Analytics Dashboard" button when reviews_count is 0
- Only show action buttons for completed jobs with reviews
TECHNICAL DETAILS:
Structural Matching Logic:
- Scans all divs for review indicators:
* hasAuthor: img with photo/avatar in src
* hasRating: aria-label containing "star" or "rating"
* hasText: span with 20+ characters
* hasDate: text matching date patterns (day/week/month/year)
- Element is a review if it has 3+ of these indicators
Early Detection Patterns:
- Checks page text for: "no reviews yet", "be the first to review", etc.
- Checks for "0 reviews" patterns in text and aria-labels
- Checks if reviews tab is disabled or aria-disabled
Benefits:
- Works on Lithuanian hospital page (was getting 0/271 reviews)
- Handles regional Google Maps variations automatically
- Faster exit for businesses with no reviews
- More reliable across Google Maps UI updates
- Better UX: no empty analytics dashboard for 0-review jobs

Performance improvements:
- Validation speed: 59.71s → 10.96s (5.5x improvement)
- Removed 50+ console.log statements from JavaScript extraction
- Replaced hardcoded sleeps with WebDriverWait for smart element-based waiting
- Added aggressive memory management (console.clear, GC, image unloading every 20 scrolls)
Scraping improvements:
- Increased idle detection from 6 to 12 consecutive idle scrolls for completeness
- Added real-time progress updates every 5 scrolls with percentage calculation
- Added crash recovery to extract partial reviews if Chrome crashes
- Removed artificial 200-review limit to scrape ALL reviews
Timestamp tracking:
- Added updated_at field separate from started_at for progress tracking
- Frontend now shows both "Started" (fixed) and "Last Update" (dynamic)
Robustness improvements:
- Added 5 fallback CSS selectors to handle different Google Maps page structures
- Now tries: div.jftiEf.fontBodyMedium, div.jftiEf, div[data-review-id], etc.
- Automatic selector detection logs which selector works for debugging
Test results:
- Successfully scraped 550 reviews in 150.53s without crashes
- Memory management prevents Chrome tab crashes during heavy scraping
