FAQ
Questions and answers
Everything clients ask before we start: how we work, specialization, contract, reporting, GEO/AEO.
How long have you been on the market?
Since 2011. Over 14 years we have delivered 50+ projects for clients in 18 countries. The team has 12 people: developers, designers, SEO specialists and project managers.
How do you work if the client is in another city or country?
For clients who can’t come to a meeting in person, we work via Zoom or Google Meet. We hold online calls to align on stages and discuss project results.
What is the company’s main specialization?
Six areas: mobile app development (Flutter and native), websites and online stores, SEO, GEO/AEO optimization, paid search advertising, marketing strategy and audit. Full cycle: from audit and prototype to launch and support.
What are the main advantages of working with Chyzh Agency?
One point of contact instead of five contractors. Development, design, SEO and ads in a single team. An official Google Partner, so we work with beta advertising tools before their public release. We support the project for at least six months after launch.
How is the relationship with the client formalized?
We work under a contract with fixed stages, deadlines and budget. At the start we agree on the scope of work, then every two weeks we show interim results. Payment is by stages.
What is a digital agency?
A full-cycle company that develops and promotes digital products: websites, mobile apps and online stores. Chyzh Agency combines development, design, SEO and advertising under one roof.
Do you provide project reports?
Yes. For SEO and ads: a monthly report with key metrics (traffic, rankings, leads, budget). For development: a weekly status update and interim results every two weeks.
What are GEO/AEO and why do they matter for business?
GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) make sure your business gets cited in ChatGPT, Perplexity and Google AI Overviews. Classic SEO gets you into the blue links. GEO and AEO put you inside the AI answer above them. It matters because 40% of Google searches now end in an AI answer before the first click.
