Ad account screenshots.Client names hidden under NDA, numbers as in the account.

ONLINE SCHOOL · SOROBAN

The school earned back 10× its ad spend from new audiences

Before
Launches didn't pay back: enquiries came in, but only a handful reached payment.
What we did
Rebuilt the messaging for the paying segment, moved optimisation from clicks to payments, connected end-to-end analytics down to the till.

REAL ESTATE · DEVELOPER

60,000+ enquiries and $1.1M revenue on property projects

Before
Enquiries came from random people, rarely reached a deal, and the sales team wasted time.
What we did
Focused on buyers who could afford the property, split flows by product, digitised the path enquiry→viewing→deal.

EDUCATION ABROAD

217,000 enquiries at $3.12 and 150 clients a month

Before
Growth hit a ceiling: with a bigger budget the cost per enquiry shot up.
What we did
Built a system of dozens of rotating ad and audience combinations, held the cost per enquiry at volume, reached a stable 150 clients a month.

What people usually ask

If yours isn't here, ask in the request or on Telegram.

01When can I expect results?

Paid ads bring the first enquiries within days of launch, and the cost per enquiry settles in 2⁠–⁠3 weeks.

Social media, organic reach and brand take months: we build the strategy, positioning and channels first.

02Do you only do ads?

Besides ads, we build websites and landing pages and run social media, content, analytics and offline promotion.

We look at positioning, the customer journey to purchase and how you handle enquiries before adding ads.If the job can be done without an ad budget, we start there.

03Where does the work start?

The work starts with a free business review.

We go through the product, audience, current channels, strengths, weaknesses and growth points, then propose only what will bring results.

04Do you work from a template?

We build a separate strategy for every project.

A local business, a service company, a venue, a salon and a brand each need a different audience and a different approach.

05What's included in a marketing campaign?

The work covers analysis, strategy, positioning, content, social media, offline tools, ads, testing, optimisation and more budget for what pays off.

We pick the mix for the business goal and don’t tie ourselves to one tool.

06Who runs 404 AFFILIATE?

404 AFFILIATE was founded by Mikhail and Kirill.

Mikhail runs ads and analytics: 5+ years in paid ads; before 404 AFFILIATE he ran a media-buying team with an ad budget of over $100,000 a month.Kirill runs strategy and social media: 3+ years in digital, social media and offline marketing.

07Where are you based and which countries do you work with?

We work remotely with clients in Bulgaria, Ireland, the UK and the EU, in English, Bulgarian and Russian.

09How much does Facebook advertising cost for a plumber in Ireland?
