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 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

## ❓ Troubleshooting
|
|
|
|
### Getting 0 reviews?
|
|
- Make sure `headless: false` in config.yaml
|
|
- Check your URL is correct
|
|
- Run again (sometimes GDPR page needs retry)
|
|
|
|
### Too slow?
|
|
- Check your internet connection
|
|
- Close other browser windows
|
|
- Make sure SeleniumBase is updated
|
|
|
|
### Missing some reviews?
|
|
- Increase `max_scrolls` in the script (default: 35)
|
|
- Or use `start_ultra_fast_complete.py` for guaranteed 100%
