Google Search Console

Pull search performance data, index coverage, and Core Web Vitals from Google Search Console API.

Prerequisites

Requires Google OAuth credentials:

• GOOGLE_CLIENT_ID
• GOOGLE_CLIENT_SECRET
• A valid OAuth access token with https://www.googleapis.com/auth/webmasters.readonly scope

Set credentials in .env, .env.local, or ~/.claude/.env.global.

Getting an Access Token

# Step 1: Authorization URL (user visits in browser)
echo "https://accounts.google.com/o/oauth2/v2/auth?client_id=${GOOGLE_CLIENT_ID}&redirect_uri=urn:ietf:wg:oauth:2.0:oob&scope=https://www.googleapis.com/auth/webmasters.readonly&response_type=code&access_type=offline"

# Step 2: Exchange code for tokens
curl -s -X POST "https://oauth2.googleapis.com/token" \
  -d "code={AUTH_CODE}" \
  -d "client_id=${GOOGLE_CLIENT_ID}" \
  -d "client_secret=${GOOGLE_CLIENT_SECRET}" \
  -d "redirect_uri=urn:ietf:wg:oauth:2.0:oob" \
  -d "grant_type=authorization_code"

# Step 3: Refresh expired token
curl -s -X POST "https://oauth2.googleapis.com/token" \
  -d "refresh_token={REFRESH_TOKEN}" \
  -d "client_id=${GOOGLE_CLIENT_ID}" \
  -d "client_secret=${GOOGLE_CLIENT_SECRET}" \
  -d "grant_type=refresh_token"

Listing Available Sites

curl -s -H "Authorization: Bearer ${GSC_ACCESS_TOKEN}" \
  "https://www.googleapis.com/webmasters/v3/sites" \
  | python3 -c "
import json, sys
data = json.load(sys.stdin)
for site in data.get('siteEntry', []):
    print(f\"{site['siteUrl']}  |  Permission: {site['permissionLevel']}\")
"

The site URL format is either https://example.com/ (URL prefix) or sc-domain:example.com (domain property).

5. Opportunity Identification

Use Search Console data to find SEO opportunities.

Low-Hanging Fruit: High Impressions, Low CTR

Queries with many impressions but low CTR suggest the title/description needs optimization.

# Pull queries, then filter for: impressions > 100 AND ctr < 0.03 AND position < 20
curl -s -X POST \
  "https://www.googleapis.com/webmasters/v3/sites/sc-domain%3Aexample.com/searchAnalytics/query" \
  -H "Authorization: Bearer ${GSC_ACCESS_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
    "startDate": "2024-01-01",
    "endDate": "2024-03-31",
    "dimensions": ["query", "page"],
    "rowLimit": 1000
  }' | python3 -c "
import json, sys
data = json.load(sys.stdin)
print('== Low CTR Opportunities (High impressions, low CTR, good position) ==')
print(f\"{'Query':<40} {'Page':<40} {'Impr':>6} {'CTR':>7} {'Pos':>5}\")
for row in data.get('rows', []):
    if row['impressions'] > 100 and row['ctr'] < 0.03 and row['position'] < 20:
        print(f\"{row['keys'][0]:<40} {row['keys'][1][-40:]:<40} {row['impressions']:>6} {row['ctr']*100:>6.1f}% {row['position']:>5.1f}\")
"

Striking Distance: Position 5-20

Queries ranking on page 1-2 that could be pushed to top 5 with content optimization.

# Filter for position between 5 and 20 with decent impressions
curl -s -X POST "..." | python3 -c "
import json, sys
data = json.load(sys.stdin)
print('== Striking Distance Keywords (Position 5-20) ==')
opps = [r for r in data.get('rows',[]) if 5 <= r['position'] <= 20 and r['impressions'] > 50]
opps.sort(key=lambda x: x['impressions'], reverse=True)
for row in opps[:30]:
    print(f\"{row['keys'][0]:<50} Pos: {row['position']:>5.1f}  Impr: {row['impressions']:>6}  Clicks: {row['clicks']:>4}\")
"

Cannibalization Detection

Find queries where multiple pages compete for the same keyword.

# Pull query+page data, then group by query to find duplicates
curl -s -X POST "..." | python3 -c "
import json, sys
from collections import defaultdict
data = json.load(sys.stdin)
query_pages = defaultdict(list)
for row in data.get('rows', []):
    query_pages[row['keys'][0]].append({
        'page': row['keys'][1],
        'clicks': row['clicks'],
        'impressions': row['impressions'],
        'position': row['position']
    })
print('== Keyword Cannibalization (multiple pages for same query) ==')
for query, pages in sorted(query_pages.items(), key=lambda x: -sum(p['impressions'] for p in x[1])):
    if len(pages) > 1:
        total_impr = sum(p['impressions'] for p in pages)
        if total_impr > 100:
            print(f\"\nQuery: {query} ({total_impr} total impressions)\")
            for p in sorted(pages, key=lambda x: -x['impressions']):
                print(f\"  {p['page'][-60:]}  Pos: {p['position']:.1f}  Impr: {p['impressions']}  Clicks: {p['clicks']}\")
"
