## 1. Organic Search KPIs

### Organic Sessions

| Attribute | Detail |
|-----------|--------|
| **Definition** | Number of visits to your site originating from organic (unpaid) search engine results |
| **Formula** | Count of sessions where medium = "organic" |
| **Data Source** | ~~analytics (Google Analytics, Adobe Analytics, or equivalent) |
| **Good Range** | Growing month-over-month; 3-10% MoM growth is healthy |
| **Warning** | Decline >10% MoM without known seasonal cause |
| **Segmentation** | Always separate brand vs. non-brand organic sessions |

**Interpretation:**
- Growing organic sessions with stable conversion rate = SEO strategy is working.
- Growing sessions but declining conversions = traffic quality issue; check keyword targeting.
- Flat sessions despite new content = content not ranking or cannibalizing existing pages.

### Organic Click-Through Rate (CTR)

| Attribute | Detail |
|-----------|--------|
| **Definition** | Percentage of search impressions that result in a click to your site |
| **Formula** | (Organic Clicks / Organic Impressions) x 100 |
| **Data Source** | ~~search console |
| **Good Range** | >3% overall; varies significantly by position and query type |
| **Warning** | <1.5% overall or declining trend |
| **Segmentation** | By query type (brand vs. non-brand), by page, by position range |

**Benchmarks by Position:**

| Position | Expected CTR Range |
|----------|-------------------|
| #1 | 25-35% |
| #2 | 12-18% |
| #3 | 8-13% |
| #4-5 | 4-8% |
| #6-10 | 2-5% |
| #11-20 | 0.5-2% |

**Interpretation:**
- High impressions but low CTR = title tags and meta descriptions need optimization.
- CTR declining for stable positions = SERP features (AI Overview, PAA) stealing clicks.
- CTR higher than position benchmarks = strong brand recognition or compelling snippets.

---

### Average Position

| Attribute | Detail |
|-----------|--------|
| **Definition** | Mean ranking position across all tracked keywords or queries |
| **Formula** | Sum of all positions / count of keywords |
| **Data Source** | ~~search console (query-level), ~~SEO tool (keyword-level) |
| **Good Range** | <20 for tracked keywords; improving trend |
| **Warning** | >30 or rising (worsening) trend |
| **Segmentation** | By keyword group, by page, by intent type |

**Interpretation:**
- Average position is a directional indicator, not an absolute measure. A few very low-ranking keywords can drag the average down significantly.
- Always pair with keyword distribution (how many keywords in top 10, top 20, etc.) for a complete picture.

---

### Keyword Visibility Score

| Attribute | Detail |
|-----------|--------|
| **Definition** | Weighted score combining keyword positions and search volumes into a single index |

| **Warning** | Declining trend for 3+ consecutive weeks |
| **Segmentation** | By topic cluster, by competitor |

**Interpretation:**
- Visibility score accounts for both ranking position and keyword importance (volume).
- A single high-volume keyword moving from #1 to #5 can cause a larger visibility drop than 20 low-volume keywords dropping off page 1.

---

| **Formula** | Count of valid indexed pages in Index Coverage report |

| **Good Range** | Indexed count close to total intended indexable pages; growing with new content |
| **Warning** | Indexed count dropping without intentional removal; large gap between submitted and indexed |
| **Segmentation** | By sitemap, by content type, by subdirectory |

**Interpretation:**
- Indexed < submitted = quality or technical issues preventing indexing.
- Sudden drop in indexed pages = possible noindex tag, robots.txt change, or manual action.
- Indexed > intended = duplicate content, parameter URLs, or faceted navigation issues.

---

| Attribute | Detail |

| **Warning** | <30% (over-reliance on brand awareness, not SEO) |
| **Segmentation** | Trend over time |

**Interpretation:**

- Low non-brand share = organic traffic is mostly people who already know your brand; SEO is underperforming for acquisition.
