ChronoSearch 作者： Clerical Studio

Turn Google Search into a competitive intelligence dashboard. Track rolling trends, reverse-engineer historical campaigns, and lock custom date ranges in one click.

Stop fighting with Google’s hidden search filters. Whether you are an SEO professional tracking indexation, a retail marketer reverse-engineering last year's holiday campaigns, or a B2B analyst monitoring a rolling news cycle, generic date filters like "Past Month" or "Past Year" aren't efficient enough for deep competitive research.

ChronoSearch is a professional-grade research extension that injects intelligent, dynamic timeframe templates directly into your native Google Search navigation bar. It does the complex date-math for you, allowing you to filter the web with enterprise-level precision.

The ChronoSearch Toolkit Includes 6 Dedicated Modes:

1. The Daily Pulse Tracker: For newsjacking and PR monitoring. Instantly filter search results by the past 3 Days, 2 Days, 24 Hours, 8 Hours, or 4 Hours to cut through the noise and see exactly what is indexing right now.
2. Seasonal Echo (Strict True YoY): Built for retail marketers and accountants. This uses 4-5-4 retail calendar logic to subtract exactly 52 weeks from the current date, guaranteeing you are comparing this business week to the exact same business week last year (Monday to Sunday).
3. Seasonal Echo (Broad 3-Week): Generates a dynamic 3-week rolling window centered around today's exact date last year. Perfect for reverse-engineering competitor ad campaigns and seasonal promotions.
4. Historical Quarters: For financial and market analysts. Instantly scope your search to strict quarterly bounds (Q1, Q2, Q3, Q4) for any specific year.
5. B2B Prospecting: A clean, rolling 30-day window to quickly find the latest news, funding rounds, or PR releases for cold outreach.
6. Precision Week Archive: Dial into a specific ISO week number and year to isolate historical events exactly as they happened.

Core Features:

The Filter Lock (🔒): Pin your favorite timeframe so every subsequent Google Search you perform automatically defaults to that exact date range.

Native UI Injection: ChronoSearch buttons look and feel exactly like Google's native UI. No clunky external calendars or popups on your search page.

Smart Memory: Your dropdown selections and active toolkits are saved locally, meaning your workflow is always exactly how you left it.
