Analytics: SEO Monitoring

Guides building a holistic SEO data analysis system. Covers four core metrics (indexing, traffic, keywords, backlinks), benchmark setup, article database, tool selection, traffic diversification, penalty recovery, and work document management.

When invoking: On first use, if helpful, open with 1-2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope

Core metrics: Indexing, traffic, keywords, backlinks
Benchmark: Natural traffic baseline; trend comparison
Article database: Per-article performance tracking
Tool selection: GA4, GSC, Semrush, Umami, PostHog, etc.
Traffic diversification: Healthy source mix
Penalty recovery: Algorithm impact, fix workflow
Work documents: Monthly records, responsibility tracking

Four Core Metrics

1. Indexing

Metric	Purpose	Data Source
Pages indexed / not indexed	Coverage; early focus: all target pages indexed	GSC, site: command, Semrush (Organic Research > Pages)
Keyword count per page	More keywords = more potential traffic	Semrush
Index coverage	Target pages indexed; functional pages findable	GSC, site: command

Early priority: Ensure all pages that need to rank are indexed.

2. Traffic

Metric	Purpose	Data Source
Total traffic	Growth; keyword relevance (irrelevant traffic has little value)	GA4, Semrush
Subdirectory traffic	Per-section performance; concentration vs dispersion	Semrush, GA4
Competitive comparison	Organic, keyword traffic, total clicks vs competitors	Semrush, Similarweb
Organic by page / country	Granular breakdown	GA4, GSC

3. Keywords

Metric	Purpose	Data Source
Rank changes	Target keyword movement	GSC, Semrush
Keyword count	New gains / losses per page	Semrush, GSC

4. Backlinks

Metric	Purpose	Data Source
Referring domains vs backlinks	Ratio; directory links can be high volume but low value	Semrush, Ahrefs, Moz
Backlink quality	Do links drive traffic? Low ROI = deprioritize	Semrush, GA4 (referral)

Natural Traffic Benchmark

Location: GA4 > Reports > Acquisition > Traffic acquisition

Review organic traffic trend
Record baseline (e.g., monthly total)
Compare periodically to detect growth or decline

Tip: Add CTA events on key articles to track content ROI (see analytics-tracking).

Article Database

Track per-article performance to find high/low patterns:

Field	Use
URL, publish date, target keywords	Content metadata
Index status, rank, traffic, backlinks	Performance
vs benchmark or competitors	Context

Use to guide topic selection, optimization, and resource allocation.

Tool Selection

Use	Tools
Precise attribution	GA4, GSC, Bing Webmaster, Yandex Webmaster
Visit analytics	Umami, Plausible, Clarity (Microsoft), Superset
Third-party estimates	Semrush, Similarweb
Open-source GA alternative	PostHog
SEO data	Semrush, Ahrefs, Moz

Attribution config:

User ID: Cross-device, cross-session identification; send to GA4
GSC API: Index, clicks, impressions, coverage for automation, dashboards

Choose by privacy, cost, and team workflow.

Traffic Diversification

Principle	Guideline
Search share	Keep organic search below ~75% of total
Health	Higher direct + referral share = healthier
Brand sites	Diversified traffic is common for strong brands
Non-brand	Possible without brand (e.g., tool sites)
Reputation	Site/brand reputation matters; Google assessors evaluate it
Engagement	Content, email, social, free tools drive return visits

Penalty Recovery

Step	Action
Identify	Which algorithm update caused the impact
Analyze	Site issues; draft fix plan
Assess cost	Decide if fixes are worth it; sometimes abandoning is best
Execute	Implement changes; wait at least 3 months until next major update
Parallel	Use other channels for quality traffic; improve engagement data for Google
Data window	Google typically uses ~6 months of data for site quality
Recovery	Outcome is uncertain; do what you can, then wait
