Why Trend-Data Scrapers Silently Fail (And How I Fixed It)

Google Trends scrapers often fail silently due to rate limiting and aggressive endpoint defense. They incorrectly assume a consistent response format and fail to handle 'no' responses. To fix, use a residential proxy and strip the XSSI guard sequence, rather than relying on a specific separator. This highlights the importance of testing against the real endpoint, not just a mock, to catch assumptions.
