FAQ
How does the crawl budget estimator work?
Enter your site metrics — total pages, average page size, server response time, crawl errors %, duplicate content %, and faceted-nav URL count. The tool estimates the effective crawl budget using a faceted-nav penalty, computes a heuristic crawl rate (pages/min), crawl efficiency %, and time to full crawl, then generates prioritized recommendations.
What formula is used?
Effective budget = totalPages × (1 − duplicatePct/100) × (1 − facetPenalty), where facetPenalty = min(facetUrlCount/totalPages, 0.5). Crawl rate (pages/min) = 60000 / (avgServerResponseMs + avgPageSizeKb/10). Efficiency = budget / totalPages × 100. These are heuristics, not Google's actual algorithm.
What recommendations does the tool suggest?
Six rules: canonical tags for duplicate content, robots.txt blocks for faceted nav params, TTFB optimization, image/Brotli compression for large pages, GSC crawl error fixes, and internal-linking improvements when efficiency is below 70%.
What extra features does this tool have compared to others?
(1) Input validation. (2) Crawl budget formula with faceted-nav penalty. (3) Crawl rate estimation (pages/min). (4) Crawl efficiency %. (5) Time-to-full-crawl estimate. (6) Recommendation generator (6 rules). (7) Score visualization 0-100 with color. (8) Text report renderer. (9) CSV renderer. (10) Copy + Download .txt + Download CSV. (11) History (localStorage, last 20). (12) Shareable URL. (13) Site size presets (small/medium/large/enterprise). (14) Comparison mode (current vs optimized inputs).
Is my data sent anywhere?
No. All calculations run locally in your browser. History is stored in localStorage on this device only.
