Quick answer: Hooked on Media is a social and paid media agency that drives visibility through advertising spend on platforms like Google Ads, Meta, LinkedIn, and TikTok. MarGen is a Sheffield-based GEO and AEO specialist that builds organic AI citation authority — visibility that does not require ad spend. The choice depends on whether you want to pay for every impression or build a compounding asset in AI-generated answers.
Overview: Paid Visibility vs Organic AI Authority
This comparison is less about two agencies and more about two fundamentally different visibility models.
Hooked on Media delivers paid media results. Their expertise is in crafting ad campaigns, managing budgets, and driving measurable returns from paid channels — social advertising, PPC, display, and video. When the campaigns run, visibility exists. When they stop, it disappears.
MarGen delivers organic AI citation authority. Their methodology builds the entity signals, structured data, and content architecture that causes AI models to cite your business unprompted. This visibility compounds over time and does not require ongoing ad spend to maintain.
Both models have legitimate use cases. But they operate on entirely different economics, and understanding those economics is essential before choosing an agency partner.
Hooked on Media — Who They Are
Hooked on Media is a UK-based social and paid media agency that specialises in driving growth through advertising across major platforms. Their focus is on creating, managing, and optimising paid campaigns that generate measurable business results.
Key strengths of Hooked on Media:
Paid social expertise. Hooked on Media understands the mechanics of social advertising across Meta (Facebook and Instagram), LinkedIn, TikTok, and other platforms. They can build targeted campaigns that reach specific audiences based on demographics, interests, and behaviour.
PPC and paid search management. Google Ads and Bing Ads management ensures visibility at the top of search results for high-intent keywords — though this visibility exists only while the budget supports it.
Immediate results. Unlike organic strategies that take weeks or months to deliver measurable outcomes, paid media can generate traffic, leads, and conversions within days of campaign launch.
Performance tracking. Paid media provides clear, immediate attribution. Cost per click, cost per acquisition, return on ad spend, and other metrics are measurable in real time.
Creative production. Social media advertising requires strong creative — ad copy, images, video. Hooked on Media produces the creative assets alongside the campaign strategy.
MarGen — The Organic AI Visibility Approach
MarGen is a Sheffield-based agency focused entirely on Generative Engine Optimisation. Rather than buying visibility through ad spend, MarGen builds the authority signals and content infrastructure that cause AI models to cite your business organically.
Key strengths of MarGen:
Zero ad spend required. MarGen’s GEO methodology builds citation authority that AI models use when generating answers. Once established, this visibility persists and compounds without ongoing advertising costs.
Compounding returns. Unlike paid media where stopping spend means stopping visibility, GEO authority accumulates. Content published and optimised today continues to influence AI citations months and years later.
Multi-platform AI coverage. MarGen tracks and optimises for ChatGPT, Perplexity, Claude, Google AI Overviews, and Microsoft Copilot — platforms where paid advertising does not exist or has minimal influence.
Trust and authority signals. AI models cite sources they assess as authoritative and trustworthy. MarGen builds the entity authority, schema markup, and citation patterns that establish this trust across AI platforms.
Regulated sector expertise. MarGen specialises in financial services, legal, healthcare, and construction where paid media is subject to strict advertising regulations, but organic citation authority faces fewer restrictions.
The Economics: Renting vs Owning Visibility
The most important distinction between these two agencies is the economic model of the visibility they create.
Paid media is rented visibility. Every impression, every click, and every lead costs money. When the budget stops, the visibility stops. Industry benchmarks for UK businesses show:
- Average cost per click for Google Ads in competitive B2B sectors: £2-£15
- Average cost per lead from paid social (LinkedIn B2B): £30-£100+
- Monthly management fees for paid media agencies: typically 10-20% of ad spend or £1,000-£5,000+
- Total annual investment for meaningful paid visibility: £30,000-£200,000+
GEO is owned visibility. The investment goes into building entity authority, citation infrastructure, and content assets that AI models reference organically. The cost structure is fundamentally different:
- Monthly GEO retainer: a fixed investment regardless of “impressions” or “clicks”
- No per-click or per-impression costs
- Authority compounds over time — month six delivers significantly more visibility than month one for the same investment
- Visibility persists even during periods of reduced investment
This does not mean paid media is wasteful. For immediate results, product launches, event promotion, and markets where AI-generated answers are not yet dominant, paid media delivers. But for long-term, compounding visibility in the AI-generated answer space, the economics of GEO are fundamentally more efficient.

The AI Advertising Blind Spot
There is a critical strategic point that many businesses miss when comparing paid and organic approaches in 2026: you cannot buy your way into AI-generated answers.
When someone asks ChatGPT “Who are the best financial advisers for pension transfers?” or Perplexity “Which law firm handles commercial property disputes in Manchester?” — the answer is generated by the AI model based on its assessment of authority, relevance, and trustworthiness. There is no ad placement. There is no bidding system. There is no way to pay for inclusion.
This means paid media, however effective it is on Google and social platforms, has zero influence on the fastest-growing discovery channel in digital marketing. The only way to appear in AI-generated answers is to build the authority signals that AI models use to determine which sources to cite. That is GEO.
When to Choose Hooked on Media
Hooked on Media is the right choice if:
- You need immediate visibility and leads — there is no time to wait for organic authority to build
- Your market is primarily driven by social media discovery and paid search
- You have a product launch, event, or time-sensitive campaign that requires rapid reach
- Your industry’s buying decisions happen primarily through social platforms and Google search ads
- You have budget for ongoing ad spend and want professional management of that spend
When to Choose MarGen
MarGen is the right choice if:
- You want visibility that compounds over time without requiring ongoing ad spend
- AI-generated answers are influencing buying decisions in your sector
- You operate in a regulated industry where paid advertising faces compliance restrictions
- You want to be the brand AI models cite — not the brand that appears in the ad slot above the AI answer
- Your competitors are being cited by ChatGPT, Perplexity, or Google AI Overviews and you are not
- You recognise that AI-generated answers cannot be bought — only earned through authority
The Bottom Line
Hooked on Media and MarGen are not competitors — they are complementary. Paid media delivers immediate, measurable visibility on platforms where advertising exists. GEO delivers compounding, organic visibility on AI platforms where advertising does not.
The strategic question is where to allocate your next pound of marketing investment. If AI-generated answers are already shaping how your market discovers and evaluates providers, every month without GEO is a month your competitors are building citation authority that you will need to overcome.
