Our work approach?

A new collaboration starts with us scaning editorial, technological and other specifics of a website. We conceptualize a strategy and ad placement proposition. Furthermore, we implement the strategy - in this stage of collaboration the publisher is minimally involved. Sometimes, the publisher is not involved at all because in the implementation stage we can do everything by ourselves.

We connect the publisher with the source of programmatic advertising - e.g. Google AdExchange, OpenX, Criteo. We use machine learning technology which creates a demand pressure on advertisers, resulting in higher profitability rates for publishers.

We optimize. In the long run - our goal is to increase income while ensuring great user experience and fast page load times.

What does the collaboration process with 234 look like?

For starters, we need some information about your website. We will make an analysis and let you know if we can help and how. Further details will be provided.

How much does our service cost?

We provide risk-free service. The price is defined as a percentage of the profit we bring you. If we don't bring you extra profit you don't need to pay us. This is our guarantee.


Majority of Ad impressions we serve are in South-East Europe (Adriatic) region. If you'd like to access more than 1 000 000 000 impressions we serve monthy, please get in touch. Implementation methods we can support are - Header bidding & private deals.



AdExchange is an exchange where publishers (supply) and advertisers (demand) meet. It is highly customisable. AdSense is a plug&play solution which provides fill rate of 100%. AdExchange has larger potential for your profit growth than Adsense but to use that potential you need an advanced setup which most of web publishers do not have at their disposal.


Header bidding is a technological solution in programmatic advertising which was developed as a response to the traditional waterfall model.

The waterfall model brings together ad networks in a serial connection.

Waterfall works like this- Firstly, the opportunity to place ads is given to the network with the highest priority. If first network does not fill the ad slot than the opportunity is given to the next network and so on.

The main advantage of header bidding is that it gives the opportunity to a potentially unlimited number of networks to compete for every impression simultaneously, which results in higher CPM rates and more profit for web publishers.

2 different implementation approaches are present - client side (for example prebid.org) and server side (Google Exchange Bidding).


Yes. We encourage only placing ads which don't compromise good user experience. If you want to block a certain advertiser or ad format this can be done.


No. Directly sold deals stay uncompromised even with programatic supporting setup. Different setups are available to utilize maximum advantage from both direct and programatic deals.
