Looking for a Google Ads specialist (Display / YouTube / PMax) for a Telegram Mini App

Hello.

I am looking for a specialist/agency to work with advertising campaigns.

We have a product — a game in Telegram. The advertising landing pages are already ready, and we use Keitaro for lead tracking and connections.

We need not just a one-time launch of the advertising account, but ongoing work on testing and optimizing advertising campaigns, analyzing connections, selecting traffic sources, creatives, and geos.

We are primarily interested in cheap traffic sources:

— Google Display Network / Display;

— YouTube;

— Demand Gen / PMax;

— other sources, if you have experience with them.

Search can also be considered, but we assume that search traffic will be more expensive, so our main interest is in display/YouTube and similar formats.

In your response, please indicate:

1. Do you have experience with GDN/Display/YouTube/PMax?

2. Have you worked with Keitaro or similar trackers?

3. What is the minimum budget needed for testing?

4. How much do your services cost?

5. Do you have case studies for similar projects?
