# Google Search Console SQLite Ingestion & SQL Analytics

The `search-analytics` skill ingests Google Search Console performance metrics into a local SQLite analytics database (`search_analytics.db` or `$XDG_DATA_HOME/search-analytics/analytics.db`) without data loss, preserving all raw JSON payloads, handling API quotas via 25,000 batch chunks, and providing direct SQL querying over indexed search traffic.

## Available scripts - `scripts/search_analytics.py`: Automated sync, reporting, and OAuth CLI for Google Search Console. Executed via `uv run scripts/search_analytics.py` (requires Google Cloud OAuth credentials). - `scripts/test_search_analytics.py`: Unit and regression test suite validating schema, query extraction, and CLI flags.

## ⚡ Quick Start & Primary Actions

All operations are driven via the bundled Python script in `scripts/search_analytics.py`:

```bash # 1. Authenticate with Google OAuth 2.0 uv run scripts/search_analytics.py auth --port 8080

# 2. Incremental Sync (Updates newest days + 3-day latency overlap) uv run scripts/search_analytics.py sync --db path/to/database.db

# 3. Full Historical Backfill (Ingests up to 16 months of granular daily data) uv run scripts/search_analytics.py sync --full --db path/to/database.db

# 4. Run Pre-Built SQL Reports uv run scripts/search_analytics.py report overview --db path/to/database.db uv run scripts/search_analytics.py report top-queries --db path/to/database.db uv run scripts/search_analytics.py report top-pages --db path/to/database.db uv run scripts/search_analytics.py report countries --db path/to/database.db uv run scripts/search_analytics.py report devices --db path/to/database.db uv run scripts/search_analytics.py report timing --db path/to/database.db uv run scripts/search_analytics.py report milestone-impact --db path/to/database.db

# 5. Run Ad-Hoc SQL Query uv run scripts/search_analytics.py query "SELECT query, SUM(clicks), SUM(impressions) FROM search_performance GROUP BY query ORDER BY SUM(clicks) DESC LIMIT 10" --db path/to/database.db ```

If `--db` is omitted, the script defaults to `search_analytics.db` in the current working directory.

## 🗄️ Database Schema & Relational Structure

The database maintains 6 relational tables and 7 high-performance analytical views. Detailed DDL and schema definitions are in [`references/schema.md`](references/schema.md).

### Tables

1. **`daily_site_performance`**: Unfiltered property-level daily totals (`dimensions: ['date']`). Matches 100% of property clicks/impressions in the Search Console web interface and 28-day Achievement badges. - Key columns: `id` (PK), `site_url`, `date`, `search_type`, `clicks`, `impressions`, `ctr`, `position`, `raw_json`, `synced_at`. 2. **`search_performance`**: Granular keyword-level performance partitioned by query, page, country, and device. - Key columns: `id` (PK), `site_url`, `date`, `query`, `page`, `country`, `device`, `search_appearance`, `search_type`, `clicks`, `impressions`, `ctr`, `position`, `raw_json`, `synced_at`. 3. **`properties`**: Verified Search Console web properties. - Key columns: `site_url` (PK), `permission_level`, `raw_json`, `synced_at`. 4. **`sitemaps`**: Submitted XML sitemaps, error counts, and indexed URL counts. - Key columns: `site_url`, `path` (PK), `type`, `last_downloaded`, `last_submitted`, `errors`, `warnings`, `indexed_count`, `raw_json`, `synced_at`. 5. **`site_milestones`**: Release milestones and publication launches for cohort impact analysis. - Key columns: `commit_hash` (PK), `event_date`, `title`, `description`, `category`, `scope`, `author`, `created_at`. 6. **`sync_history`**: Audit log of backfill and incremental sync operations. - Key columns: `id` (PK), `site_url`, `sync_type`, `start_date`, `end_date`, `rows_synced`, `status`, `error_message`, `started_at`, `completed_at`.

## 🔍 Common SQL Analytics Recipes

Pre-tested SQL query recipes are documented in [`references/queries.md`](references/queries.md).

### 1. High-Opportunity Search Queries (Rank 1-10, Low CTR) ```sql SELECT query, page, ROUND(SUM(impressions), 0) AS imps, ROUND(SUM(clicks), 0) AS clks, ROUND((SUM(clicks)/SUM(impressions))*100, 2) AS ctr_pct, ROUND(AVG(position), 1) AS avg_rank FROM search_performance WHERE position <= 10 GROUP BY query, page HAVING SUM(impressions) >= 500 AND ctr_pct < 3.0 ORDER BY imps DESC LIMIT 15; ```

### 2. Keyword Cannibalization Detection ```sql SELECT query, COUNT(DISTINCT page) AS competing_pages, GROUP_CONCAT(DISTINCT page) AS pages, ROUND(SUM(clicks), 0) AS total_clicks, ROUND(SUM(impressions), 0) AS total_impressions FROM search_performance WHERE query != '' GROUP BY query HAVING COUNT(DISTINCT page) > 1 ORDER BY total_impressions DESC LIMIT 10; ```

## ⚠️ Critical Architecture: Property-Level Totals vs. Keyword-Level Breakdown

When querying and analyzing Search Console data, note the two distinct API behaviors and database tables:

1. **Unfiltered Property-Level Totals (`daily_site_performance`):** - Querying the GSC API with `dimensions: ['date']` (and `aggregationType: 'byProperty'`) returns **100% of property search traffic**, including all rare and long-tail queries. - This data is ingested into `daily_site_performance` and powers `v_daily_summary`. It directly matches the Search Console Web UI Performance graphs, Total Clicks cards, and 28-day Achievement badges (e.g. *700 clicks in 28 days*). 2. **Granular Keyword-Level Breakdown (`search_performance`):** - When querying the GSC API with `dimensions: ['query', 'page', 'country', 'device']`, Google automatically applies **anonymized query filtering** to protect searcher privacy, stripping out rare/unique queries. - On technical and developer blogs, long-tail anonymized queries often represent 50%–70% of total search traffic. Therefore, `search_performance` should be used for keyword rankings and page distributions, while `daily_site_performance` (or `v_daily_summary`) must be used for aggregate traffic totals. 3. **Cross-Engine Reconciliation with Google Analytics 4:** - GA4 records landing sessions under `session_default_channel_group = 'Organic Search'` across all search engines (Google, Bing, DuckDuckGo, etc.) without privacy filtering. - GA4 Organic Search traffic naturally aligns with Search Console property-level totals (`daily_site_performance`), rather than the query-filtered `search_performance` table.
