AI can help teams write synthetic tests and investigate incident evidence, but it does not change the core job of website monitoring: detect failures that affect users, confirm them with relevant signals, and route them to people or carefully controlled automation that can respond. A green homepage check is not proof that checkout works, and an unusual metric is not automatically an outage.
What does website monitoring cover?
Website monitoring checks whether important parts of a web service are available and behaving as expected. Depending on the service and the risks a team needs to manage, that can include endpoint reachability, response latency, expected response content, broken links, page rendering, and multi-step user journeys such as login or checkout.

Google Cloud Monitoring supports uptime checks for HTTP, HTTPS, and TCP endpoints, as well as synthetic monitors that run scripted tests. A synthetic workflow can exercise a login page, checkout flow, or API calls to third parties; teams can configure alerting policies for failures. Results include execution times, errors, and logs, providing evidence to investigate rather than only a pass-or-fail signal (Google Cloud synthetic monitoring documentation).

Metrics, logs, traces, alerts, and service objectives help teams understand what failed, where, and with what effect. Google Cloud lists synthetic monitoring, uptime monitoring, SLO monitoring, metrics, and alerting among Cloud Monitoring features (Google Cloud Monitoring). Cloudflare describes observability tools for logs, traces, recurring errors, trends, alerts, telemetry export, and dashboards (Cloudflare Observatory documentation).
What has changed: AI can help create tests and investigate incidents
AI-assisted synthetic test creation
Google Cloud documentation says eligible projects can prompt Gemini Code Assist to generate synthetic test code. That can help teams get from a described workflow to a test more quickly, but the resulting test still needs review: it must check the right user outcome, handle the site’s authentication and data requirements, and fail when the workflow is genuinely broken (Google Cloud synthetic monitoring documentation).
AI-assisted incident investigation
Google SRE describes AI-generated incident hypotheses with suggested verification steps and links to relevant dashboards or logs. These suggestions can help an on-call engineer investigate evidence, but they are hypotheses to verify—not a guarantee that a cause has been found or that an incident can be resolved automatically (Google SRE, “AI in SRE: How Google is Engineering the Future of Reliable Operations”).
What is the difference between synthetic monitoring and real-user monitoring?
Synthetic monitoring runs simulated, repeatable tests under selected conditions. It is useful for checking a known journey consistently and for comparing behavior before and after a code change. Its coverage is limited to the paths and conditions the team chose to test.

It can expose variation that a scripted test will miss and report interaction measures such as Interaction to Next Paint (INP), which synthetic tests do not provide in the same way. Cloudflare describes both synthetic and real-user signals in its Observatory documentation (Cloudflare Observatory documentation).
Use the two as complementary evidence: synthetic tests give predictable checks of selected journeys; RUM shows how real visitors experience the service. Neither alone represents every user or every failure mode.
How do I monitor website uptime?
- Choose the endpoint and protocol. Identify the service users depend on, then configure an HTTP, HTTPS, or TCP uptime check as appropriate. A check of the homepage is useful, but it answers only whether that endpoint responded under the check’s conditions.
- Define what counts as healthy. Where the check supports it, verify expected response content as well as reachability. A successful network connection can still return an error page or incorrect content.
- Set a useful alert policy. Route failures to the team responsible for the service and connect the alert to the relevant results, errors, and logs. Choose thresholds and evaluation behavior that distinguish a meaningful problem from a transient blip.
- Exercise the workflows that matter. Add synthetic monitors for critical tasks and dependencies rather than assuming an endpoint check covers the whole service. Google Cloud documents scripted synthetic tests and alerting on their failures (Google Cloud synthetic monitoring documentation).
- Review alerts against user impact. Use logs, metrics, traces, synthetic results, and RUM where available to determine what users experienced and what action is warranted.
How do I monitor a checkout flow?
Monitor checkout as a journey, not just as a page load. A useful synthetic test should follow the meaningful steps your service supports—for example, reaching the checkout page, submitting required details, and confirming that the expected next state appears. The exact script depends on the site’s flow, authentication, and test-data setup; Google Cloud documents synthetic workflows for checkout and other scripted user journeys (Google Cloud synthetic monitoring documentation).
Keep the test safe and repeatable. Use test accounts and data where possible, avoid actions that create real orders or charges, and ensure the script detects a failed or unexpected state rather than merely completing browser interactions. Pair the synthetic result with logs or traces when investigating a failure; use RUM to see whether live visitors are encountering related friction.

What has not changed—and what common signals cannot prove
A working homepage does not establish that the service works
A homepage check cannot establish that login, checkout, or a critical API dependency is healthy. Test the workflows tied to user and business outcomes, including dependencies where their failure would block those outcomes.
A synthetic pass does not represent every visitor
A scripted test runs under selected conditions. It cannot capture the full range of real-user networks, devices, browsers, and extensions; use RUM evidence to understand live variation.
An anomaly is not automatically a user-impacting incident
Google SRE cautions that “Statistical anomalies in system metrics within noisy production environments don’t always equate to user impact, largely because these signals lack a deep understanding of user intent.” The article notes that a feature launch or a normal traffic shift can look unusual without indicating a failure. Verify whether users and important journeys are affected before treating an anomaly as an outage (Google SRE).
An alert is useful only if it leads to a safe response
Alerts should identify an actionable condition, reach someone who can respond, and provide evidence that helps them investigate. AI-generated findings do not replace an accountable on-call process or verification of a proposed cause.
Automated production changes need safeguards
Google SRE describes a safety gateway for AI-driven production actions, including preflight validations such as dry runs, checks that an action corresponds to an open incident, and escalation when the system reaches its operating limits. This is Google’s described approach, not a universal standard; teams considering automated changes need authorization, validation, and clear limits appropriate to their own services (Google SRE).

Before adopting or expanding a monitoring setup, assess it against the service’s actual needs rather than relying on a single uptime number or an AI feature list.
- User journeys and dependencies: Can it test the workflows and third-party services whose failure would matter to users?
- Evidence type: Does it provide synthetic checks, real-user evidence, or both?
- Coverage: Which geographic locations, devices, browsers, and network conditions are represented?
- Response workflow: Can alerts reach the right people and link to useful logs, traces, metrics, and test results?
- Data and network constraints: Does data regionality meet your requirements, and can checks run through the network paths your service needs?
- Automation controls: Are proposed or executed actions authorized, validated, bounded, and escalated when needed?
- Recurring cost: What will execution frequency cost at the planned scale, including any charges from services used by the tests?
Examples of current platform details to verify
Google Cloud’s published Cloud Monitoring pricing lists uptime-check executions at $0.30 per 1,000 executions, effective October 1, 2022, and synthetic-monitor executions at $1.20 per 1,000 executions, effective November 1, 2023. These are Google Cloud prices with those stated effective dates, not market-wide rates; the pricing page also describes free allotments and warns that a synthetic execution may incur charges from other Google Cloud services. Check the current billing page before budgeting or purchasing (Google Cloud Monitoring pricing).
Google Cloud’s synthetic monitoring documentation says uptime-check and synthetic-monitor data regionality is not guaranteed to remain in a specific geographic location and identifies restrictions for certain Assured Workloads and IL4 requirements. Teams with residency or compliance constraints should review the current documentation against their applicable requirements before relying on these checks (Google Cloud synthetic monitoring documentation).
