Customer Effort Score (CES): API & Analytics Integration

A user fills out a registration form, clicks "Submit," but nothing happens. A minute later, they leave — a lost lead. Such friction points can be identified with CES (Customer Effort Score). We have implemented CES surveys on dozens of sites — from B2B SaaS to e-commerce. Result: a 15% reduction in churn per quarter. In this article, we'll dive into how to integrate a CES survey into a website using Laravel and React, configure triggers, and analyze results.

Why CES Is More Accurate Than Other Metrics

CES is a metric that predicts churn better than NPS. The question: "How easy was it to resolve your issue?" Scale 1–7. A low score (1–3) signals the user is exerting excessive effort. In our system, it automatically generates a support ticket. Research shows that 70% of users who encounter difficulties switch to competitors (according to Customer Effort Score on Wikipedia).

CES wins in accuracy for B2C and transactional scenarios. For example, in e-commerce after checkout or in SaaS after onboarding — precisely at these moments the user assesses effort, and we can react promptly.

How We Integrate the CES Survey

The process includes stages: analytics → design → implementation → test → deploy.

1. Analytics: define measurement points — onboarding, support, checkout, integration. Select triggers (time on page, number of form steps).
2. Design: decide where the widget appears — popup, inline, after action. Configure scale (7 points with markers).
3. Implementation: write the API in Laravel (see example below) and the React widget using useState. Backend validates score (1–7) and journey. If score ≤ 3, a SupportTask is created.
4. Test: check on mobile devices, different scenarios (quick response, skip, repeated display). Ensure responses are recorded in the database.
5. Deploy: roll out on server via CI/CD, set up response monitoring.

On one project, we integrated CES after each support ticket. Within a month, the average score rose from 4.2 to 6.1, and repeat tickets dropped by 30%.

What's Included in the Work

• API endpoints for collecting and analyzing CES responses.
• React widget in source code with comments.
• Documentation for integration and trigger configuration.
• Access to an analytics dashboard updated in real time.
• Team training on the system.
• Technical support during implementation.

Example API and Widget

API Route

// CesController
public function store(Request $request): JsonResponse
{
    $request->validate([
        'score' => 'required|integer|min:1|max:7',
        'journey' => 'required|string|max:100', // 'onboarding', 'support', 'checkout'
        'comment' => 'nullable|string|max:500',
    ]);

    CesResponse::create([
        'user_id' => auth()->id(),
        'score' => $request->score,
        'journey' => $request->journey,
        'comment' => $request->comment,
    ]);

    // If CES <= 3 — create a task for the support team
    if ($request->score <= 3) {
        SupportTask::create([
            'type' => 'low_ces_followup',
            'user_id' => auth()->id(),
            'notes' => "CES {$request->score} for {$request->journey}. Comment: {$request->comment}",
        ]);
    }

    return response()->json(['success' => true]);
}

React Widget

const SCALE = [
  { value: 1, label: 'Very\nhard' },
  { value: 2, label: '' },
  { value: 3, label: 'Hard' },
  { value: 4, label: 'Neutral' },
  { value: 5, label: 'Easy' },
  { value: 6, label: '' },
  { value: 7, label: 'Very\neasy' },
];

export function CesWidget({ journey }: { journey: string }) {
  const [selected, setSelected] = useState<number | null>(null);
  const [done, setDone] = useState(false);

  const submit = async (value: number) => {
    setSelected(value);
    await fetch('/api/ces', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ score: value, journey }),
    });
    setDone(true);
  };

  if (done)
    return <p className="text-sm text-green-600">Thank you! Your feedback helps us improve.</p>;

  return (
    <div>
      <p className="text-sm font-medium mb-3">How easy was it to complete this process?</p>
      <div className="flex gap-2">
        {SCALE.map(({ value, label }) => (
          <button
            key={value}
            onClick={() => submit(value)}
            className={`flex-1 py-2 rounded border text-sm font-medium transition-colors ${
              selected === value
                ? 'bg-blue-600 text-white border-blue-600'
                : 'border-gray-300 hover:border-blue-400'
            }`}
          >
            {value}
            {label && (
              <span className="block text-xs text-gray-400 whitespace-pre-line leading-tight">
                {label}
              </span>
            )}
          </button>
        ))}
      </div>
      <div className="flex justify-between text-xs text-gray-400 mt-1">
        <span>Very hard</span>
        <span>Very easy</span>
      </div>
    </div>
  );
}

SQL Query for Analytics

SELECT journey,
       ROUND(AVG(score), 2) AS avg_ces,
       COUNT(*) AS responses,
       COUNT(*) FILTER (WHERE score <= 3) AS low_effort_count
FROM ces_responses
WHERE created_at >= now() - interval '30 days'
GROUP BY journey
ORDER BY avg_ces ASC;

How to Interpret a Low CES Score

Scores 1–3 indicate high effort. We recommend immediately creating a support ticket and analyzing the corresponding funnel. If the average CES is below 5 for a month, it's worth revisiting the UX. Typical support cost savings from proactive problem identification are 20–30%, significantly reducing operational costs.

Typical CES Implementation Mistakes

• Asking CES too early — before the action is completed.
• Using a 5-point scale instead of 7.
• Not showing the widget after an error occurs.
• Ignoring responses with score 3 — they are already a red zone.

Timeline and Cost

Widget with follow-up logic: 1–2 business days. Full cycle with analytics and dashboard: 5–7 days. Cost depends on complexity and scope of integration. Get a consultation — we will assess your project.
