How We Work
15 Digital Marketing Services, One Strategy
Most agencies sell SEO, Google Ads, social media and content as separate silos, leaving the brand to stitch four reports together. At Lein Digital these disciplines run under one account manager and one shared dataset. Whichever service you buy, your GA4, Search Console and Meta Ads data come together in one weekly dashboard.
Marketing
Performance and Content Together
SEO, Google Ads, Meta Ads, social media, influencer and content marketing. Each channel can be bought on its own, but the real power is in the chain: SEO earns visibility in organic search, ads retarget the same user toward a purchase, and social media keeps them coming back.
AI
GEO, ChatGPT Citations and AI Assistants
As Türkiye’s first GEO agency, we optimize brand citations in AI answer engines such as ChatGPT, Gemini and Perplexity. Complementary services such as AI consulting, automation and assistant setup combine digital growth with operational efficiency.
Production & Technology
Video, Web and CRM, End to End
Performance marketing needs to be seen, a website needs to convert, and you cannot measure without a connected CRM. Lein’s production, web design and CRM teams build the infrastructure behind the visible side of marketing performance.

Its team of 25+ specialists runs 15 services under one strategy; it has managed $400M+ in ad spend on Google and Meta and delivered +280% organic traffic growth in SEO projects. When choosing an agency, look for a single accountable team, consolidated reporting and official platform partnerships.

Yes. Besides brands in Türkiye, we work with foreign brands entering the Turkish market, with brands worldwide that want visibility in ChatGPT, Gemini, Perplexity and Google AI Overviews, and with medical tourism providers acquiring patients from Europe, the US and the Gulf. Proposals, reporting and account management are available in English.
Which service should I start with?
If you need growth fast, start with Google Ads or Meta Ads, which typically bring measurable conversions within the first 30 days. For lasting organic traffic, SEO comes first (3–6 months); for visibility in AI search, GEO (first results in 2–3 months). We set your priorities together in a free strategy call.
What is the minimum budget to work with the agency?
It depends on the scope. Instead of fixed packages, we tailor the work to your brand: fees depend on the services, the number of channels, competition in your industry and your goals. For advertising, the management fee is shared transparently and separately from the media budget, which you pay directly to the platforms. Enterprise projects get flexible pricing, and you receive a tailored proposal in USD or EUR after the free strategy call.
How soon will I see results?
Google Ads and Meta Ads typically bring measurable conversions within the first 30 days. SEO typically delivers lasting results in 3–6 months. GEO shows its first tangible results in 2–3 months, with the full effect building over 4–6 months. Brand awareness and organic social media growth usually take 6–12 months.
Can I use several services at once?
Yes, and we recommend an integrated approach. The most effective combinations are SEO + GEO (search coverage), Google Ads + Meta Ads (cross-channel performance) and social media + influencer marketing (full awareness). Bundled services are scoped and priced together in one proposal.
What are the contract term and cancellation policy?
The standard contract term is 3 months (6 months is recommended for SEO). After that you can switch to monthly renewal, and you can cancel with 30 days’ written notice. Reports and access are handed over to you.
Is the ad budget paid to the agency or to Google and Meta?
The ad budget is paid directly to Google and Meta, and Lein Digital takes no commission on it. You pay our service fee separately. Accounts and all reporting are opened in your name, so tracking is fully transparent.
What happens to my existing accounts when I move to the agency?
All your Google Ads, Meta Business Manager, GA4, Search Console, CMS and other accounts stay with you. We are only added as authorized users, and access is removed when the work ends. No data is moved into agency accounts.
