Choosing a maintainer: 12 "bulleted" criteria to ask clearly

1. SLA & priority P1/P2/P3:

• P1 (site down, payment error, hack/redirect) how long does it take to respond? Is there a written SLA (e.g. P1 ≤ 2h)?

2. Safety procedures:

• Is there staging to test before pushing to production? Is there 1-click backup/rollback? Where to save change log?

3. Security:

• Check malware, firewall (WAF), hardening server/WordPress? Monthly vulnerability patching plan?

4. Performance:

• Optimize Core Web Vitals (LCP/INP/CLS), cache/CDN/HTTP/2/3 configuration?

5. SEO thoroughly Technical:

• Regularly review robots/sitemap/canonical? Fix error index/404/5xx/structured data?

6. Content & UI/UX “small but powerful”:

• Is there a update banner, landing, article package? Fix JS/CSS broken interface layout?

7. Infrastructure & monitoring:

• Monitor uptime, alert 5xx/CPU/RAM/IO? Does SSL/domain renewal have automatic reminders?

8. Scope & exclusion commitments:

• Clearly list inclusions/exclusions (e.g. new feature development, third-party integration).

9. Human resources & replacement So:

• Is there a on-call team or is it dependent on one dev? When the dev quits, who replaces him? Payroll/Outsource?

10. Reporting & transparency:

• Report monthly/quarterly, stating tickets handled, incident – cause – fix – prevention?

11. Account & ownership Ownership:

• Standard Decentralized SOP (owner/admin/editor), account belongs to business or agency?

12. Price & volume scale:

• Calculated by hourly package or SLA/head job? How is overtime calculated? Is there a response time commitment?

Sample workflow (to compare when receiving proposals)

1. Startup (Week 1):

• Technical audit (security, speed, technical SEO), backup testing, staging, agreement on SLA – communication channel – process ticket.

  month):

• Supervised security updates, testing on staging, monthly reports (incidents – solutions – recommendations).

4. Quarterly upgrades:

• CWV optimization, heavy JS/CSS refactor, light UI/UX improvements, technical SEO & index review health.

RFP question (send to 2–3 vendors for fair comparison)

• Response/remediation SLA for P1/P2/P3? For example, P1 ≤ 2 hours, P2 ≤ 1 day…

• Scope of maintenance: infrastructure (domain/hosting/SSL) + application (WordPress/Framework) + technical SEO + performance?

• Security: malware scan, WAF, hardening, access log, administration key/secret?

• Deployment process: required staging, approver, rollback?

• Report: format, KPI, delivery schedule?

• Price & overage: how to calculate overtime/out of scope fees?

When should you choose “operational agency” vs. “infrastructure”?

• Choose an operating agency (for example, Tan Phat Digital, Mona Media) when you need:

  • Be responsible for end-to-end for the website (fix problems, patch hacks, optimize speed, technical SEO, update interface - content).

  • Quarterly improvement plan (not only “keep running”).

• Choose the infrastructure (Mat Bao, VinaHost, PA, iNET, AZDIGI...) when you need:

  • Optimized server/hosting, uptime, resources, 24/7 monitoring, OS/Stack level support.

  • Coordinate with internal team/agency to handle the application (theme/plugin, technical SEO).

• Choose eCommerce platform (Haravan, Chili) when you need:

  • Fast launch, platform maintenance is taken care of by the provider, you focus on content & marketing campaigns.

  • Accept limited customization according to the framework platform.

Suggested implementation roadmap (first 90 days)

• Days 1–7: sign SLA, audit & clean up “instant vulnerabilities” (P1), set up monitoring.

• Days 8–30: standardize robots/sitemap/canonical, patch old plugins/themes, optimize base CWV version.

• Days 31–60: backup/rollback standardization, incident tracking & index health dashboard, SSL/domain renewal checklist.

• Days 61–90: UX refinement (mobile screens), static resource consolidation, quarterly planning (A/B CTA, improved conversion rate change).

“Maintenance” is planned operation, not just “firefighting”

An effective maintenance contract must help the website stable – fast – secure – easy to index – easy to convert. The Top 10 list above gives you a starting point:

• If you want a focal point responsible for overall from P1 troubleshooting to routine maintenance and performance optimization/technical SEO, Tan Phat Digital is the choice to put on the first shortlist.

• If you have a strong internal dev team, consider combining a vendor layer to optimize server/uptime, while dev handles application.

• For eCommerce that needs to deliver products quickly, platform is the shortest path, then add content/marketing human resources.

Suggested next steps: choose 2–3 units from the list, send RFP according to the above set of questions, compare SLA – scope – process – report report – costs. Sign a contract for a minimum of 3–6 months to have enough data to measure and evaluate effectiveness.
