Warranties and SLAs in digital: how to write them down

Clients expect predictable results and transparent rules of cooperation. In digital, this means not only a brief and KPIs, but also clearly defined guarantees and SLAs. A properly executed document eliminates risks, speeds up work approval, and protects both parties. Below is a practical approach based on live cases and processes that teams work with in the full cycle of projects: from strategy to technical support.

🚀 What are guarantees and SLAs and how do they differ

Definition without “water”

A guarantee is a promise regarding the quality or performance of a specific result. For example, fixing software defects within 30 days. SLA (Service Level Agreement) is an agreement on the level of service. It fixes the metrics of response, availability, deadlines, escalation, and reporting. The warranty is responsible for the “what”, the SLA is responsible for the “how” and “when”.

Key metrics without which SLA does not work

Typical indicators: availability (uptime) as a percentage, response time to requests, incident resolution time, percentage of critical errors, meeting backlog deadlines. For marketing services, KPIs such as CPA, CTR, ROAS, or share of visibility are added.

Where useful links are appropriate

In the context of support and guaranteed stability, it is appropriate to fix the SLA within the technical support of the site. For complex products, SLAs are integrated with the website development stage, where responsibility for releases and warranty bug fixes are determined.

🧭 How to write an SLA correctly: structure and wording

Service scope and area of responsibility

Describe what exactly is included in the service. For example, 24/7 monitoring, incident management, CMS updates, backups, security patches. At the same time, specify what is not included. This reduces the “gray area” and disputes.

Metrics and priority levels

Agree on the criticality of tasks in advance. For P1 (critical): response time up to 30 minutes, recovery up to 4 hours, target uptime 99.5-99.9%. For P2 (high): response time up to 2 hours, resolution up to 1 business day. For P3 (medium): in a planned sprint. Such a framework should be included in the contract, not in correspondence.

Escalation, reporting and financial consequences

Describe the 3 levels of escalation: contractor, team leader, project manager. Specify the format of reports: monthly SLA reports with dashboards. Provide compensation mechanisms: for example, a 5-10% discount on the monthly cost in case of violation of the agreed metrics, or additional hours of work.

📊 SLAs in different areas of digital: realistic commitments

Development and support

In development, warranties are appropriate for the error-free operation of the approved functionality, and SLAs are appropriate for responding to incidents after the release. It is recommended to fix the following: test coverage, acceptance processes, hot fixes for critical bugs, and deadlines. These agreements naturally integrate with website design and further development so that requirements are not lost at the junction of stages.

SEO: what can be guaranteed and what can’t

It is inappropriate to guarantee positions in search projects. Realistic guarantees are the implementation of the agreed work plan, transparent SEO optimization of the site, technical audit, improvement releases, and reporting. The SEO SLA focuses on the response time to critical technical errors, the speed of implementing changes, and the regularity of analytics. When signing a contract for SEO services, it is correct to mention the forecasted traffic ranges, not the “top 1 tomorrow”.

For businesses looking for systematic search engine promotion, the contract should mention all related activities. For example, a content plan, technical backlog, link building, indexing control, and conversion improvement.

PPC and SMM: KPIs and SLAs in media buying

In paid performance, KPIs at the account or campaign level are appropriate: target CPA/ROAS in the middles, conversion tracking accuracy, frequency of optimizations and A/B tests. SLAs record the speed of response to moderation failures, CPM/CTR spikes, and tracking failures. For transparent interaction with the media buying team, specify responsibility for creatives, landing pages, and analytics.

It is appropriate to combine a detailed SLA with tool services such as Google ADS contextual advertising and META ADS targeted advertising. And if part of the activity is carried out through social media, use separate annexes to contracts for SMM promotion, Facebook advertising, or Instagram branding to set out requirements for the content plan, moderation, and responses to comments.

🛡️ Legal and operational nuances that are often overlooked

Scope changes and SLA revisions

Provide a mechanism for reviewing SLAs once a quarter. This allows you to adjust the metrics for seasonality, new traffic procurement plans, or CMS changes. It is important to define that changes take effect after signing an additional agreement.

Monitoring and evidence base

Write down which systems are the source of truth. For uptime, it is the hosting monitoring log. For campaign performance – website analytics and advertising accounts. For SEO promotion – an agreed dashboard. This eliminates disputes over data.

Formulations that make life easier

• Criticality of tasks: P1 – website unavailability, massive payment error. P2 – incorrect templates, tracking failures. P3 – scheduled tasks.
• Communication: official channels – service desk and email. Working hours: 10:00-19:00 EET on weekdays. Duty on P1 is 24/7.
• Finance: small bonuses – for exceeding KPIs in the 10% corridor. A small penalty – for failure to meet SLA for two months in a row.

The WonderWeb team works in a full cycle. This means that guarantees and SLAs are agreed upon comprehensively: from hypotheses and design to launch and support. Customized solutions without templates, 20+ specialists in the team, and more than 150 completed projects allow us to prescribe realistic, measurable commitments without “air”.

Do you need to transfer your current cooperation to a transparent format or start with a properly executed contract? Don’t hesitate to contact WonderWeb. We will agree on metrics, set up processes, and fix an SLA that works for the result.

What exactly should the metrics section of an SLA contain?

Specify uptime 99.5-99.9%, response time: P1 up to 30 minutes, P2 up to 2 hours, recovery time, and regularity of reporting (monthly with dashboards). This creates a measurable basis for service control.

How to write a proper SLA for SEO to avoid false guarantees?

Do not guarantee positions. Fix the work plan, technical implementations, response times to critical errors, and frequency of analytics. Predict traffic ranges instead of “top 1” promises.

What is the difference between a warranty and an SLA in development and support?

The warranty covers the performance of the agreed functionality (for example, bug fixes within 30 days). The SLA defines the processes and time: response, recovery, escalation, and reporting, in particular for P1/P2 tasks.

What if the contractor violates SLA metrics for two months in a row?

Provide a compensation mechanism: a 5-10% discount or additional hours of work. This should be specified in the contract along with a three-level escalation and monthly SLA reports.

How often should SLAs be reviewed and who initiates changes?

It is optimal to review it once a quarter. Changes are approved by an additional agreement to take into account seasonality, CMS updates, or new media buying plans.
