Why
Focus one metric at a time
Stacked bar charts hide fluctuations; toggle off other metrics to see each clearly
Don't compare just two points
End-of-month vs prior month misses mid-month drama; examine full trend
Check beyond top 10
Many reports default to top 10; scroll or paginate for more rows
Screenshot charts
GSC retains limited history; save images for future reference
Record in spreadsheet
Export at month-end; use formulas to track correlations over time
Track release dates
Join dev standups, read release notes; correlate GSC shifts with deployments
Investigation Workflow
- Pinpoint date: When did the metric change?
- Correlate: Any releases, CMS changes, server maintenance, third-party code?
- Decide: Investigate, correct, overlook, or monitor closely
- Loop in: Product or dev team for root cause
Key Reports & Metrics
1. Performance (Search Results)
Location: Performance ? Search results
Metric
Use
Clicks
Traffic from Google Search
Impressions
How often site appeared in results
CTR
Whether users think page answers query
Average position
Ranking trend
Dimensions: Query, page, country, device, date. Filter by search type: web, image, video, news. Use to find low-CTR high-impression pages (title/meta optimization opportunities).
Search appearance: AMP, blue link, rich results (filterable in UI and API).
#### CTR Benchmarks by Position
Use to compare actual CTR vs expected. Benchmarks vary by SERP features (AI Overviews, featured snippets). Zero-click: When SERP features satisfy intent without a click, organic CTR drops; factor into expectations. See serp-features (Zero-Click section), featured-snippet. Clean SERPs:
Position
Expected CTR (baseline)
With AI Overviews (lower)
1
25-35%
~19%
2
12-18%
~12%
3
8-12%
~7%
4-5
5-7%
~5%
6-10
2-5%
2-5%
Interpretation: If actual CTR is below expected for your position, prioritize title/meta optimization. Over 90% of first-page results have CTR below 10%; significant upside exists.
#### Low CTR, High Impressions: Optimization Workflow
- Identify: Sort by impressions; filter positions 1-10; 1,000+ monthly impressions
- Compare: Actual CTR vs expected for position (see table above)
- Gap: e.g., position 4 at 2% CTR vs expected 5-7% ? ~3-5% uplift potential
- Action: Optimize title and meta per title-tag, meta-description; add schema for rich results (+10–20% clicks)
#### Rich Results & CTR
Pages with review stars, FAQ schema, or other rich snippets see 10-20% more clicks. See schema-markup.
2. Insights Report
Location: Performance ? Insights (or Overview)
Simplified overview; replaces standalone Search Console Insights. Data from GSC only (GA data removed Dec 2024).
Card
Use
Clicks and impressions
Site visibility and click effectiveness
Your content
Top, trending up, trending down pages
Queries leading to your site
Top, trending up, trending down queries
Top countries
Geographic audience
Branded vs non-branded
Brand recognition (AI-labeled; may mislabel)
Additional traffic sources
Image, Video, News search, Discover
Trending: Based on click change vs previous period. Click items to jump to Performance report filtered to that item.
Query groups: Similar queries grouped; group name = best-performing query. Not available for sub-properties or low-impression sites.
3. Page Indexing (Coverage)
Location: Indexing ? Page indexing
Status grouping (updated): Valid + Valid with warning ? Indexed. Error + Excluded ? Not indexed.
Indexed vs Not indexed are complementary: Not all site content should be indexed. Login, admin, duplicate content, legal boilerplate, and low-value pages often intentionally use noindex. Indexed and non-indexed pages can reference each other (e.g., sitemap includes indexable URLs; noindex pages still exist and link internally). Non-indexed is not inherently a problem--investigate only when important pages are excluded. See indexing (noindex usage) and robots-txt (crawl control) for when to exclude.
Metric
Action
Pages indexed
Turn off "Pages not indexed" to view alone; watch for drops
Pages not indexed
Turn off "Pages indexed" to view alone; watch for spikes. Distinguish intentional (noindex, robots) from accidental
Filter: All submitted pages / Unsubmitted pages only (dropdown near top).
Source column: Indicates whether issue is caused by website or Google.
Why pages are not indexed: Drill into reasons and example URLs. Common culprits:
- Duplicate content
- Noindex tags
- Redirect errors
- 5xx errors
- 404 errors
- Blocked by robots.txt
- Discovered ? currently not indexed
- Crawled ? currently not indexed
Quick check: If trend line is stable, spend ~3 seconds; move on. Investigate if fourth column (trend) shifts.
Diagnosis workflow: GSC Coverage ? click Issue ? view sample URLs ? identify pattern ? fix (see indexing for fix actions).
Coverage issue types:
Issue
Meaning
Next step
Crawled - currently not indexed
Crawled but not indexed
See indexing
Excluded by "noindex" tag
Intentionally excluded; often valid (login, admin, legal, etc.)
Ignore if expected; verify important pages not accidentally noindexed
Blocked by robots.txt
Crawl blocked
See robots-txt; may be intentional
Redirect / 404
Redirect or missing
Fix URL or redirect
Duplicate / Canonical
Duplicate content
Usually OK; keep canonical
URL Inspection: Verdicts: "URL is on Google," "URL is on Google, but has issues," "URL is not on Google." Use for important pages; verify canonical, internal links, sitemap; Request indexing if needed.
4. Video Indexing (If Applicable)
Location: Indexing ? Video indexing
- Videos indexed / Videos not indexed: Toggle off the other for clear view
- Why videos are not indexed: Thumbnail blocked, invalid size/format, not in main content, etc.
See video-optimization for video SEO; youtube-seo for YouTube.
5. XML Sitemaps
Location: Indexing ? Sitemaps
Check
Action
Status
Confirm each sitemap says "Success"
URLs indexed
Click sitemap ? see indexed count; drops indicate indexing issues
Bellwether sitemaps
For large sites, monitor templated sitemaps (by country, language, division)
Enterprise: Glitches can block new URL crawling, cause hreflang confusion, delay fresh content discovery.
6. Core Web Vitals
Location: Experience ? Core Web Vitals
Priority: Mobile first (Google's higher expectations for mobile).
Metric
Mobile
Desktop
Good URLs
Target
Secondary
Needs improvement
Fix
Monitor
Poor URLs
Fix
Monitor
Why URLs don't have good score: Click "Open report" → grouped example URLs by issue type. For threshold values and fixes, see core-web-vitals.
Tip: Historical chart is short; export to spreadsheet for longer trends. Share with dev team regularly; correlate dates with releases.
Layout (updated): Two tables--Poor or Need improvement; Good (click "View data about usable pages").
7. Enhancements (Rich Results)
Location: Experience ? Enhancements (Product snippets, Merchant listings under Shopping)
Status (updated): Two-tier?invalid (critical issues, may not appear) vs valid (no critical issues; may still have warnings). Warnings no longer top-level.
Type
Examples
Content
Breadcrumbs, FAQ, Events, Videos (see video-optimization), Job postings, Review snippets, Q&A, Discussion forums
Shopping
Product snippets, Merchant listings
Other
Recipes, Datasets, Hotels, Vacation rentals, Profile pages, Practice problems, Math solvers, Image metadata
Note: Reports show sample items, not full list. Use URL Inspection for unlisted URLs.
8. AI Overviews (GSC Limitation)
- GSC: AI Overviews clicks/impressions are not separated from organic in Performance report.
- Workaround: Filter queries that tend to trigger AI Overviews to estimate AI-driven visibility:
(?i)^(who|what|where|when|why|how|which|is|are|can|does|should)|\b(vs|versus|compare|difference|pros and cons|guide|tutorial|best|top|list)\b
For GA4 AI traffic tracking, see ai-traffic-tracking.
9. Links & Disavow
Location: Links (inbound links), Security & Manual Actions
- Links report: View links to site and pages; anchor text distribution.
- Disavow file: Submit via GSC when necessary (manual penalty, toxic links). Use sparingly; over-disavowing can harm. See backlink-analysis for when to disavow.
Search Console API
Method: searchanalytics.query() --exposes all Performance report data.
Metrics
Clicks, Impressions, CTR, Position.
Dimensions
date, query, page, country, device. Search appearance (AMP, blue link, rich results). Filter by search type: web, image, video, news.
Limits
Limit
Value
Rows per day per search type per property
50,000
Rows per response
25,000 (use pagination: startRow, rowLimit)
Data availability
2-3 days after
Tip: Run daily queries for one day of data to avoid quota. Verify data presence first (dimensions: date only, no filters).
Optimization: Gzip compression; fields parameter for partial responses; pagination for large datasets.
