Common questions

Answers

What services do you offer for Shopify shops?
We offer Shopify SEO, Klaviyo email marketing, Google Ads, social media marketing, GEO and ChatGPT Ads. Depending on the needs, we undertake audits, strategy development, implementation and ongoing optimization.
Do you also assist with developing a Shopify shop?
No, we do not offer shop development or Shopify programming. Our focus is exclusively on marketing services for existing Shopify online shops. However, we work very closely with our sister agency Onlineshop Experts GmbH, which can professionally handle shop development as a Shopify Plus agency and is the best-rated Shopify agency in Switzerland.
What is the advantage of Klaviyo email marketing for Shopify?
Klaviyo helps address existing customers systematically and generate automated revenue. Through email automations and campaigns, we strengthen customer loyalty and increase recurring revenue. The seamless integration of Shopify and Klaviyo also enables Klaviyo to be used as a powerful CRM tool and to address users with personalized messages.
For which Shopify stores are your services suitable?
Our services are aimed at Shopify online shops that want to increase their revenue, visibility and efficiency. Shops with existing traffic, product range and clear growth goals benefit particularly. We work with both small and larger e-commerce brands such as Crocs, NIKIN, bluu, Feldschlösschen or Doetsch Grether. However, we cannot adequately serve online shops with an advertising budget of less than CHF 5,000.
What does GEO bring to e-commerce and AI search systems?
GEO (Generative Engine Optimization) ensures that your shop is better understood and recommended in generative AI search systems. To achieve this, we optimize content, FAQs, long-tail keywords, product data, and structured data. In addition, we support targeted off-page measures to improve trust for our clients' shops and thereby increase the chance of being visible in AI search environments.

How to recognize good Performance Marketing partners for Shopify brands

At Onlineshop Performance GmbH we regularly see in practice: the right agency is often already recognizable by the questions it asks first. If someone only asks about budget and target group, they are usually thinking too short-term. If, on the other hand, they ask about contribution margin, repeat purchases and existing channel mix, they understand Shopify as a trading system and not just an advertising space.
