We are a premier search arbitrage and performance marketing firm. We work with Tier 1 traffic buyers, high-yield feed operators, and exclusive lead generation partners. We buy the traffic. We optimise the feeds. We take the risk.
We acquire traffic from Tier 1 networks, route it through RSoC, Bing, and Yahoo search feeds, and monetise via revenue share or pay-per-lead. Every click is filtered. Every source is compliant.
Most arbitrage operations don't survive a year. We've been running since 2006 across the US, UK, and global markets. Compliance is the discipline that keeps us in business.
We buy from Google, Meta, and native networks at scale. Every placement is compliant. Every campaign runs on official inventory. No grey traffic, ever.
Traffic is filtered, scored, and matched to the right feed — RSoC, Bing, Yahoo, or direct lead gen. Continuous testing across placements, creatives, and bids.
Revenue comes from feed revenue share or pay-per-lead. Our partners get quality traffic or qualified leads. We manage the risk so they don't have to.
We keep our partner base intentionally small. Quality over volume — every relationship is direct. We work across the US, UK, and international markets and move fast when the fit is right.
You acquire traffic from official networks and need high-quality search feeds to monetise it. We connect you to RSoC, Bing, and Yahoo feeds with revenue share arrangements. You bring the volume. We bring the infrastructure and the yield.
You operate a high-converting search or content feed and need compliant, scalable Tier 1 traffic to drive volume. We source and manage that traffic ourselves — or we connect you with buyers from our network who can.
You have a business that converts — utilities, finance, insurance, legal, home services. We handle traffic acquisition entirely at our own risk and cost, through exclusive partnerships. You pay only when results are delivered — CPA or CPL.
Criteriads is the trading brand of TheMediaFlow Ltd, commonly referred to as Media Flow. We were founded by ex-Yahoo and Google employees who understood search monetisation from the inside. Since 2006 we've operated quietly — we don't advertise, we don't pitch at conferences, and we don't have a sales team. Our track record speaks for itself: over $800M in revenue generated across nearly two decades of compliant arbitrage operations in the US, UK, and internationally.
The US is our largest market historically and remains our primary focus. We also operate across the UK and have experience in European and international markets. If you have volume in a geo we don't currently cover, we're open to discussing it.
Search arbitrage is the practice of buying traffic from paid advertising networks — Google, Meta, native — and monetising it through search feed providers. The arbitrageur earns the difference between the cost of acquiring each click and the revenue that click generates on the search feed. It requires deep knowledge of traffic quality, bidding, and feed optimisation to remain profitable at scale.
We operate RSoC (Related Search on Content) feeds alongside Bing and Yahoo search feeds, with additional direct feed partnerships across the US and UK. We are always evaluating new feeds that meet our compliance and revenue share thresholds. If you have a feed needing quality compliant traffic at volume, get in touch.
Every click we send is sourced from official, approved advertising networks — Google Ads, Meta Ads, Microsoft Advertising, and approved native platforms. We do not use bot traffic, incentivised clicks, co-registration, or any grey-area sources. Every campaign runs within the terms of service of the network it runs on. This is non-negotiable.
Yes — and it's one of the most exciting opportunities in the market right now. If you have access to a search feed, AI-driven arbitrage is one of the only genuine ways to generate automated returns at scale, effectively overnight. Sounds appealing, doesn't it? The same rules apply though: traffic must be compliant, sourced from Tier 1 networks only, and you'll need to supply ad library evidence to demonstrate source. Get it right and the returns can be significant.
Yes. We have a reporting dashboard and a full API. Whether you're a traffic buyer wanting to monitor feed performance or a partner needing programmatic access to data, we can help you configure your setup. Get in touch and we'll walk you through it.
We acquire traffic at our own cost and risk, driving it to conversion pages for your offer. You pay only for qualified leads that meet agreed criteria — no ad spend risk, no campaign management, no media buying required on your side. We operate in finance, insurance, utilities, legal, and home services verticals in the US and UK.
No. We operate entirely on performance. We invest our own capital to acquire traffic and earn through agreed CPL rates. There are no retainers, management fees, or setup costs. If the leads don't convert for you, we don't get paid.
We work with a small number of partners at any one time. Every relationship is direct — no intermediaries, no account managers.
Whether you're holding massive search volume, operating high-yield feeds, or pitching a unique CPC opportunity — let's align our algorithms.
