What Affects GEO Pricing
Several factors influence where your business falls within these ranges:
Sector Competitiveness
GEO costs more in sectors where multiple well-resourced competitors are already investing. Financial services, legal, and technology tend to be more expensive because the authority threshold for AI citation is higher.
| Sector | Typical Monthly Investment | Competitiveness |
|---|---|---|
| Professional services (accounting, consulting) | £2,000-£4,000 | Moderate |
| Legal services | £3,000-£6,000 | High |
| Financial services / IFAs | £3,000-£7,000 | High |
| B2B technology / SaaS | £2,500-£5,000 | Moderate-High |
| Healthcare / medical | £3,000-£6,000 | High |
| Construction / trades | £1,500-£3,000 | Low-Moderate |
| Recruitment | £2,000-£4,000 | Moderate |
| Education / training | £1,500-£3,000 | Low-Moderate |
Current Digital Authority
Businesses with established websites, existing backlink profiles, and some entity signals require less foundational work. A business starting from near-zero digital presence needs more intensive entity building and content creation, increasing the initial investment.
Geographic Scope
A business targeting Sheffield costs less to optimise than one targeting the entire UK, which costs less than one targeting the UK and international markets. Wider geographic scope means more content, more entity signals, and more cross-platform synchronisation.
Number of Service Lines
A specialist firm with one core service is simpler to optimise than a diversified firm with multiple service lines, each requiring separate content clusters, entity positioning, and citation targets.
Content Requirements
Some businesses have extensive existing content that can be restructured for GEO. Others need significant new content creation. Content-heavy engagements cost more because content engineering for AI citation is a specialist, time-intensive process.
GEO vs SEO Cost Comparison
| Cost Element | GEO (Monthly) | SEO (Monthly) |
|---|---|---|
| Strategy and planning | £300-£800 | £200-£600 |
| Entity building | £400-£1,200 | £0-£200 (rarely addressed) |
| Content creation | £500-£3,000 | £400-£2,500 |
| Schema deployment | £200-£600 | £100-£300 |
| Link building | £0-£500 (supporting role) | £500-£2,000 (primary lever) |
| Technical optimisation | £200-£500 | £300-£800 |
| Monitoring and reporting | £300-£800 | £200-£500 |
| Typical SME total | £1,500-£3,500 | £1,000-£3,000 |
GEO typically costs 20-40% more than equivalent SEO services because of the additional entity building, multi-platform monitoring, and content structuring work. However, the per-lead cost from GEO is often lower because AI-sourced leads convert at higher rates.
ROI Calculation: Is GEO Worth the Investment?
Here is a realistic ROI model for a UK SME investing in GEO:
Assumptions
- Monthly GEO investment: £2,500
- Average deal value: £5,000
- Close rate from AI-sourced leads: 25%
- Monthly AI-sourced enquiries after 6 months: 8-12
Monthly ROI at 6 Months
- Enquiries from AI search: 10 (mid-range estimate)
- Conversions at 25%: 2.5 deals
- Revenue: £12,500
- GEO cost: £2,500
- ROI: 400%
Monthly ROI at 12 Months
- Enquiries from AI search: 15-25 (compounding visibility)
- Conversions at 25%: 4-6 deals
- Revenue: £20,000-£30,000
- GEO cost: £2,500
- ROI: 700-1,100%
These figures are illustrative but based on typical results MarGen sees with B2B SME clients. Actual results vary significantly by sector, deal value, and conversion efficiency.
The Compounding Effect
Unlike paid advertising (where visibility stops when spending stops), GEO builds compounding assets. Entity authority, content depth, and citation history all strengthen over time. A business that invests in GEO for 12 months has a significant and durable advantage over one that starts from zero.
Hidden Costs to Watch For
When evaluating GEO agencies, watch for these common hidden costs:
- Setup fees. Some agencies charge £2,000-£5,000 upfront for initial audits and strategy. Ensure this is disclosed before signing.
- Content costs billed separately. Check whether content creation is included in the retainer or billed per piece.
- Schema deployment as an add-on. Schema markup should be included, not an extra charge.
- Minimum contract lengths. Some agencies require 12-month commitments. Three to six months is more reasonable for SMEs.
- Reporting costs. Monitoring and reporting should be included, not a premium add-on.
One-Off vs Retainer Models
Some agencies offer one-off GEO projects rather than monthly retainers:
| Model | Cost | Best For | Limitation |
|---|---|---|---|
| One-off audit | £1,000-£3,000 | Understanding your current position | No implementation |
| One-off implementation | £5,000-£15,000 | Businesses with in-house teams to maintain | No ongoing optimisation |
| Monthly retainer | £1,500-£15,000/month | Sustained visibility growth | Ongoing commitment |
| Quarterly sprints | £5,000-£12,000/quarter | Businesses with seasonal needs | Gaps between sprints |
For most businesses, a monthly retainer delivers the best results because GEO requires continuous monitoring, content updates, and signal building to maintain and grow citation rates.

Frequently Asked Questions
Is £1,500/month enough for effective GEO?
For a small business in a moderately competitive sector, yes. At this level, a good agency can deploy foundational schema, create 2-4 optimised content pieces per month, build core entity signals, and monitor citations across AI platforms. For highly competitive sectors or wider geographic scope, a higher investment is needed.
Can I do GEO for free?
You can implement some GEO fundamentals yourself — adding FAQ schema, restructuring content with direct-answer paragraphs, ensuring Google Business Profile consistency. However, effective GEO requires specialist tools for citation monitoring, expertise in entity building, and the ability to test across multiple AI platforms systematically. Most businesses find the technical demands exceed what free, DIY efforts can achieve.
How quickly will I see ROI from GEO?
Most businesses see their first AI citations within 4-8 weeks. Meaningful lead generation from AI search typically begins at 3-4 months and scales significantly from 6 months onward. Full ROI (where AI-sourced revenue exceeds GEO costs) typically occurs within 4-6 months for B2B services.
Should I reduce my SEO budget to fund GEO?
If your SEO performance is strong and stable, reallocating 20-40% of your SEO budget to GEO is a sensible approach. If your SEO still needs significant work, maintain your SEO investment and add GEO incrementally. The two disciplines are complementary — strong SEO supports GEO performance.
What happens if I stop investing in GEO?
Unlike paid advertising, GEO builds durable assets — entity authority, content depth, schema infrastructure, citation history. These do not disappear immediately when you stop investing. However, without ongoing content updates and monitoring, your citation rates will gradually decline as competitors improve and content becomes stale. Most businesses maintain at least a reduced GEO investment long-term.
