Auction Insights Trend Visualizer

How to use it

1. Export Auction Insights at a consistent daily, weekly, or monthly granularity. Every Auction Insights table needs its own Date, Week, or Month column.
2. Paste or upload one table, or separate multiple dated tables with a line containing ---.
3. Optionally add a GSC Dates export for average organic position and one same-scope Google Ads report with Search lost IS (budget). Optional blocks are identified by their headers, not their order.
4. Select Analyze, choose impression share, overlap rate, or outranking share, and toggle competitors. Download the evidence CSV or the current chart as PNG.

How to read the result

Competitor is the display URL domain from the export. Each metric retains its own exact, censored-boundary, or missing state. Dashed chart segments touch at least one censored value for the selected metric. The optional organic-position line uses a separate scale where a lower position is better; it supplies context, not evidence that paid and organic movement caused each other.

Data sources & freshness

The parser recognizes common domain and period headers, converts percentage cells to decimals, and retains the source text and censoring state for every metric. Parseable day, ISO-week, and month labels are sorted chronologically. Confirmed Google update rollout dates come from this site's dated Search Status Dashboard feed. Budget and GSCA free Google service that reports how a site performs in Google Search and surfaces problems with how Google crawls, indexes, and serves it. It's first-party data straight from Google — but you don't need it to appear in results. evidence are aligned to imported dates; no interpolation, forecasting, causal attribution, or competitor scoring is applied.

Features

• Switches among impression share, overlap rate, and outranking share.
• Accessible competitor toggles, text legend, SVG tooltips, and a source-evidence table.
• Metric-specific censored boundaries and missing values; <10% and -- are never silently converted to exact zero.
• Multiple dated Auction Insights blocks, optional GSC average-position overlay, and confirmed Google update bands.
• Optional direct budget evidence plus CSV and PNG exports, all processed locally.

Limitations

• Algorithm-update overlap is timing context, not evidence that an update caused a paid or organic change.
• GSC average position is an aggregated, directional measure on its own scale; the overlay does not create a paid/organic attribution model.
• Auction Insights alone does not reveal budgets. A budget finding requires a direct, exact Search lost IS (budget) value on a matching imported date.
• The browser can reject undated Auction Insights blocks, duplicates, unknown optional blocks, and mixed named budget scopes, but it cannot prove that separately exported reports used identical network, device, geography, campaign, or filters. Confirm that scope yourself.
