Scores
| Dimension | Score | Notes |
|---|---|---|
| Keycloak Specificity | 9/10 | KC 26 JDBC_PING + persistent sessions, KC_PROXY_HEADERS (not deprecated KC_PROXY), KC_HOSTNAME_ADMIN, RHBK |
| Content Quality | 7/10 | Strong structure, but ZERO code blocks in an infra tutorial |
| E-E-A-T Signals | 9/10 | Official sizing formula cited to keycloak.org; links to two first-party benchmark posts; honest ops-cost section |
| SEO Optimization | 7/10 | Title 71 chars; post ends on FAQ with no closing CTA |
| AI Citation Readiness | 9/10 | TLS comparison table, answer-first FAQ, sizing worked example all extraction-ready |
| Technical Accuracy | 9/10 | Version claims verified (26.6.3 current, 26.5 EOL Apr 2026); route modes and ARO domain pattern correct |
| Writing Quality | 9/10 | On-brand voice, zero em-dashes, no banned phrases |
| Overall | 8.4/10 |
Fabrication Check
PASS. Sizing numbers match the official keycloak.org sizing guide exactly (1 vCPU/15 password logins/sec, 1 vCPU/120 client-credential and refresh grants/sec, +150% headroom, ~1250 MB/pod, heap ~70%). Internal benchmark links point to real Skycloak posts. No invented metrics.
Must Fix (High Priority)
- No code blocks. An OpenShift HA tutorial with zero YAML reads as theory. Add a minimal
KeycloakCR example (replicas, db, hostname, proxy headers) in the Operator or HA section. - Post ends on FAQ with no CTA. House rule: every post ends with a natural /pricing/ CTA. Add a one-line closer after the FAQ.
- Title is 71 characters. Trim under 60.
Should Fix (Medium Priority)
- Audit checklist item 1 (event logging) should link
/docs/features/events/(Keycloak login/admin events docs). Note:/features/audit-logs/is the wrong target there, since that page covers Skycloak’s own platform audit trail, not Keycloak event logging.
Nice to Have (Low Priority)
- Featured image (optional per house policy).
- A topology diagram would help, but inline images require the WP-upload-first workflow; defer.
Internal Linking Opportunities
Present: /hosting/ (x2), /blog/keycloak-realm-scaling-how-many-realms-per-cluster/, /blog/keycloak-redis-cache-benchmark-locke-vs-infinispan/, /pricing/, /contact/. Add: /docs/features/events/. Cross-link from B1 (UAA post) once both are live: the UAA post’s destination platform is this post’s subject.
AI Citation Opportunities
The TLS route-mode table and the sizing worked example are the two passages most likely to be extracted by AI engines. The line “Keycloak sizing is driven by request rate, not by how many rows sit in the user table” is a strong standalone quotable. No changes required.
Strengths
- Leads with what changed in KC 26 (JDBC_PING, persistent sessions), which instantly dates competing 2022-era HA guides.
- The “your database is your real SLA” framing is correct and differentiating.
- Audit checklist matches what enterprise reviews actually ask for (restore drills, admin lockdown, EOL cadence) rather than generic hardening advice.
Verdict
Needs minor revision (3 must-fix items, all small). Ready to publish once applied.
