Terms & Conditions
Last updated: 9 July 2026.
Scope
These Terms & Conditions govern all service agreements between classseo GmbH, Grazer Damm 142, 12157 Berlin, Germany ("classseo," "we," "us") and any business client ("client," "you") who engages one or more of our published services (SEO Audit, On-Page SEO, Content Marketing, Technical SEO, Link Building, Local SEO). These terms apply to business (B2B) clients; where a service is purchased by a consumer, statutory consumer-protection rules take precedence over any conflicting term below.
Services and scope
Each service is scoped individually as described on its respective service page and confirmed in writing (email or a signed proposal) before work begins. The published "from €X" price on each service page is a starting price for the smallest realistic scope; final pricing depends on factors disclosed before any contract is formed (site size, number of locations, number of languages, or similar concrete factors) — never on undisclosed "complexity."
Contract term and cancellation
Retainer-based services (On-Page SEO, Content Marketing, Technical SEO, Link Building, Local SEO when sold as ongoing engagements) carry a minimum term of three (3) months from the start date, after which the agreement continues month-to-month until cancelled by either party with 30 days' written notice. One-off services (a standalone SEO Audit, a Content Sprint, a Technical Migration Audit) carry no ongoing term and conclude upon delivery of the agreed deliverable. See our Refund Policy for cancellation and refund specifics.
Client obligations
The client agrees to provide timely access to systems, content, credentials, or approvals reasonably required for classseo to perform the agreed service, and to respond to review/approval requests within a reasonable time. Delays caused by the client extending the timeline do not constitute a breach by classseo.
No guaranteed outcomes
SEO results depend on factors outside any agency's control, including search engine algorithm behavior, competitor activity, and market conditions. classseo does not guarantee specific search-engine rankings, traffic levels, or revenue outcomes for any service. Our commitment is to the scope, process, and reporting described on each service page and in any signed proposal — not to a specific ranking position.
White-hat commitment
classseo does not use, and will not be engaged to use, tactics that violate search engine guidelines, including but not limited to private blog networks (PBNs), paid link schemes, link exchanges, cloaking, or thin/spun content. We reserve the right to decline or terminate any engagement that requires such tactics.
Fees and payment
Fees are invoiced per the agreed schedule (typically monthly in advance for retainer services, or upon completion for one-off services). Prices shown on the site are net of German statutory VAT, which is added on the invoice where applicable. Invoices are payable within 14 days of the invoice date unless otherwise agreed in writing. Late payment may result in suspension of services after written notice.
Intellectual property
Deliverables created specifically for the client (reports, written content, strategy documents) become the client's property upon full payment for the relevant engagement. classseo retains the right to reference the existence and general nature of an engagement (without confidential specifics or client-identifying metrics) for its own portfolio purposes, unless the client requests otherwise in writing.
Confidentiality
Both parties agree to keep confidential any non-public business information disclosed in the course of the engagement, and to use it only for the purposes of delivering or receiving the agreed services.
Liability
classseo's liability for damages is limited to cases of intent and gross negligence, and, in cases of slight negligence, only for breach of a material contractual obligation (wesentliche Vertragspflicht), in which case liability is limited to the foreseeable, typically occurring damage. This limitation does not apply to damages arising from injury to life, body, or health, or where mandatory statutory liability applies (e.g., under the Produkthaftungsgesetz).
Governing law and jurisdiction
These terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods. The place of jurisdiction for any dispute arising from these terms, to the extent legally permissible, is Berlin, Germany.
Severability
Should any provision of these terms be or become invalid, the validity of the remaining provisions is unaffected.
