GSC + GA4 · CTR + conversions

CTR Lens

Compares two GSC periods and separates demand, ranking and CTR/query-mix effects. GA4 optionally compares key events and KER across the same periods to flag conversion risk.

How to Use CTR Lens

  1. Connect your Google Search Console account via the button in the top bar.
  2. Select a GSC site property and, optionally, a GA4 property — this adds conversion data to each page.
  3. Choose two date ranges: the current period and a comparison period (e.g., last 30 days vs. previous 30 days).
  4. Click Compare periods. The GSC table loads first; GA4 enrichment runs in the background.
  5. Once GA4 loads, three new filters appear: Conversion Risk (key events↓ + KER↓), Quality Alert (CTR↑ + KER↓) and GA4 Champion (high KER).
  6. Click any row to open the detail drawer: it includes GA4 sessions, key events, KER and period-over-period changes.
  7. Use filters and sorting to prioritise. Export to CSV for reporting.

What CTR Metrics Mean

CTR (Click-Through Rate) is the share of impressions that result in a click. A page ranking in position 1 typically expects 25–35% CTR; position 5 expects around 7–9%. When your actual CTR is lower than expected for your average position, it signals a title or description problem.

vs Expected compares your actual CTR to the benchmark for your average ranking position. A value below 1.0× means you are underperforming; above 1.0× means your snippet outperforms peers at the same rank.

Scenario Opportunity is an upper-bound estimate from a generic position CTR benchmark. It is useful for ranking qualified opportunities, but it is not a forecast or a claim that the clicks were actually lost.

Frequently Asked Questions

Why is my CTR lower than expected?
The most common reasons: an uninspiring title tag that doesn't match search intent, a meta description that gives away the answer without creating curiosity, competitors using structured data (stars, prices, FAQs), or brand unfamiliarity. Start by rewriting the title to be more specific and benefit-driven.
How many impressions are needed for reliable data?
CTR Lens filters out queries with fewer than 10 impressions per period to avoid misleading ratios. For page-level analysis, we recommend at least 100 impressions per period; for query-level decisions, 50+ impressions give a reasonably stable CTR estimate.
What is a good CTR for my ranking position?
Rough targets: position 1 → 28–35%, position 2 → 15–20%, position 3 → 10–13%, positions 4–5 → 6–9%, positions 6–10 → 2–5%. Branded queries typically have much higher CTR. The "vs Expected" column already accounts for your actual average position — focus on pages where that ratio is below 0.7×.
How do I export data from CTR Lens?
Click the Export CSV button above the results table. The file contains all visible columns: URL, impressions (both periods), clicks (both periods), CTR delta, average position, and lost clicks estimate. Open it in any spreadsheet tool to build custom reports.
