What affects the price

Number of AI platforms

An agency covering just Google AI Overviews costs less than one covering ChatGPT, Gemini, Perplexity, Claude, AI Overviews, and Copilot. The more platforms, the more monitoring and optimisation work required.

Website complexity

A 20-page professional services site costs less than a 5,000-page ecommerce catalogue. Schema, content restructuring, and entity mapping scale with site size. A 50-page site might need 2-3 days of schema work. A 5,000-page site could need automated schema generation and product-level structured data, taking weeks.

Current state

A site with good existing SEO, clear content structure, and some schema markup needs less work than one starting from zero. An initial audit reveals where you stand.

Industry competitiveness

Competitive industries (legal, financial, healthcare) cost more. There are more competitors to track and stricter compliance rules. In regulated sectors, content needs compliance review before publishing. This adds time and cost to every update.

Number of platforms covered

An agency covering just AI Overviews costs far less than one covering all six platforms. Each extra platform needs separate monitoring and different tactics. A single-platform engagement might cost £1,500/month. Full six-platform coverage could be £5,000-£8,000/month for the same size business.

Content creation requirements

Some businesses have strong content that just needs restructuring. Others need content from scratch. If your agency writes answer capsules, tables, FAQs, and blog posts on top of technical work, expect 30-50% more than a technical-only engagement. Content-heavy programmes can add £1,000-£3,000/month.

Reporting and monitoring depth

Basic monthly reports cost less than real-time citation dashboards. Enterprise clients want weekly reporting, cross-platform competitor tracking, and executive presentations. Reporting can account for 15-25% of the total retainer, especially when agencies use tools like Semrush AI Visibility or Otterly at scale.

Hidden costs to watch for

Several hidden costs catch businesses off guard. Setup fees, contract minimums, platform add-ons, and content charges can push the true cost 20-40% above the quoted price. Always ask for a full breakdown before signing.

Setup and onboarding fees

Many agencies charge a one-off setup fee for the initial audit, schema, robots.txt, and baseline measurement. This ranges from £1,000-£5,000. Some include it in the first month's retainer. Others charge it separately. Ask whether setup is included or extra.

Minimum contract lengths

Some agencies require 6 or 12-month commitments. AI search evolves fast, so a 12-month lock-in carries risk. Check for a break clause (usually 30 or 60 days' notice). Look for performance benchmarks that let you exit early if targets are missed.

Platform-specific add-ons

Watch for agencies that quote a base price for AI Overviews and then charge extra for ChatGPT, Bing, or Perplexity. These "add-on modules" cost £300-£800/month each. A good AI search strategy should cover all major platforms as standard.

Tool and software costs

Some agencies pass through tool costs. Others include them. If your agency uses Semrush (£120/month), Otterly (£25/month), or Ahrefs (£99/month), check whether those costs are included or billed separately.

Content creation as a separate line item

Technical work (schema, robots.txt, entity mapping) is different from content creation (answer capsules, blogs, FAQs). Some agencies quote for technical work only and charge separately for content. A single optimised blog post can cost £200-£500. Ongoing content adds £500-£2,000/month.

DIY cost breakdown

DIY AI search optimisation is possible but takes both money and time. The minimum tool stack costs about £127-£220 per month. Add your time at a fair hourly rate and DIY costs £800-£1,500/month total. That is cheaper than an agency but far from free.

Tool / cost	Monthly price	What you get
Semrush	£120/mo	AI Visibility module, keyword tracking, brand monitoring, competitor analysis
Otterly AI	£25/mo	AI citation monitoring across ChatGPT, Perplexity, Gemini, AI Overviews
Bing Webmaster Tools	Free	Bing indexing, sitemap submission, IndexNow implementation
Google Search Console	Free	Google indexing status, organic performance baseline
Schema markup generator	Free	Technical SEO Review, Schema.dev, or manual JSON-LD
Your time (10-15 hrs/month)	£500-£1,000 equivalent	Content restructuring, monitoring, updates, brand building

Total DIY cost: £645-£1,145/month (tools plus time value). This covers monitoring and basic optimisation. It does not include content creation time, which adds another 5-10 hours per month for most businesses.

The main trade-off is knowledge. AI search changes fast. Agencies stay current because it is their full-time job. DIY needs ongoing self-education, which adds time cost that is hard to measure.

ROI calculation examples

AI search visitors convert at 27% vs 2.1% from organic search. That is 13x higher. Even modest AI referral traffic can deliver strong ROI. Below are three worked examples across different business types and price points.

Example 1: Law firm spending £4,000/month

Metric	Value
Monthly AI search spend	£4,000
AI referral visitors per month (after 4 months)	150
Conversion rate (AI visitors)	27%
Leads generated	40
Cost per lead	£100
Average case value	£3,000
Close rate	25%
Monthly revenue from AI leads	£30,000
ROI	650%

Example 2: B2B SaaS spending £6,000/month

Metric	Value
Monthly AI search spend	£6,000
AI referral visitors per month (after 5 months)	400
Conversion rate (AI visitors)	27%
Trial sign-ups	108
Trial to paid conversion	15%
Paying customers	16
Average annual contract value	£6,000
Monthly revenue equivalent	£8,000
ROI	33% monthly, 400%+ annualised

Example 3: Local business spending £1,800/month

Metric	Value
Monthly AI search spend	£1,800
AI referral visitors per month (after 3 months)	50
Conversion rate (AI visitors)	27%
Leads generated	13
Cost per lead	£138
Average job value	£800
Close rate	40%
Monthly revenue from AI leads	£4,160
ROI	131%

These examples use the 27% conversion rate from industry data. Your actual conversion rate will depend on your website quality, pricing, and how well your service matches the intent of AI search queries about your category.

How to negotiate with agencies

AI search pricing is not yet standard. There is room to negotiate. Get three or more quotes. Ask about methodology. Start with a low-commitment engagement before scaling up.

Get at least three quotes

Pricing varies widely. Our research found quotes for the same scope can differ by 2-3x. Three quotes give you a realistic range and leverage to negotiate. Be specific in your brief so you compare like with like.

Ask about Bing

If an agency skips Bing, they are missing ChatGPT and Copilot entirely. This is a useful filter question. Agencies that mention Bing tend to have deeper AI search expertise than those focused only on Google.

Request case studies with AI-specific metrics

Many agencies repackage traditional SEO as "AI search optimisation." Ask for case studies with AI citation counts, AI referral traffic, and platform-level visibility. If an agency can only show SEO metrics, their AI search work may be limited.

Start with an audit

A £500-£2,000 audit lets you test an agency's expertise before committing monthly. The report quality reveals whether they understand AI search or just relabel SEO. Look for platform-specific actions, schema analysis, crawler access checks, and entity consistency scoring.

Negotiate the contract length

Push for month-to-month or 3-month terms. If an agency insists on 12 months, ask for a performance clause. If targets are not met by month 6, you exit without penalty. Good agencies are confident enough to agree.

Clarify what is included

Before signing, get written confirmation of what the retainer covers. This means platforms monitored, content creation, reporting frequency, schema work, and whether tool costs are included. A clear scope prevents disputes later.

What's the ROI?

AI search visitors convert at 27% vs 2.1% from organic. That is 13x higher. A business spending £3,000/month that generates 20 AI leads per month pays £150 per lead. If your average customer value exceeds £150, the ROI is positive. Most B2B and professional services businesses see payback within 3-6 months.

Frequently asked questions

Can I do AI search optimisation for free?

Basic optimisation is free: fixing your H1, adding Organisation schema, allowing AI crawlers in robots.txt, submitting to Bing. These alone can improve your AI visibility. Paid tools and agencies add monitoring, advanced schema (Speakable), entity SEO, and ongoing content optimisation.

Should I pay for an audit first?

Yes. A £500-£2,000 audit tells you where you stand before committing to a monthly retainer. Some agencies, including Rank4AI, offer free initial audits. Request a free audit here.

Are annual contracts worth it?

AI search changes fast. What works today may need adjustment in 3 months. Start month-to-month until you see results. Then consider a longer term for better rates. Avoid 12-month lock-ins with no break clause.
