Which London Agencies Handle Both AI Search and Google Ads? 6 Verified Options

Which London agencies handle both AI search and Google Ads? Six agencies with a London presence publicly describe both AI search work and paid search: AccuraCast, Brainlabs, Croud, Delante, Impression and Integrated.Social. Their models differ, so a buyer should compare evidence of delivery, team ownership and commercial measurement rather than assume that listing two services means they operate one integrated search programme.

Quick Summary

• This is a verified shortlist of six, not a ranking of the “best” agencies or a claim that no others qualify.
• Each included agency has a London presence and first-party evidence of AI search or AI-aware SEO plus paid search capability as checked on 28 September 2026.
• The publisher, Integrated.Social, is included. Its description is subject to the same public-evidence standard and appears alphabetically.
• Published service scope does not prove the two teams share a plan or attribution model. Ask for a joint workplan and examples.
• Agency fees, media spend and tool costs are separate. No comparable fee schedule for the combined brief was verified across all six.

How this guide helps you decide

1. Apply the three public-evidence inclusion tests (London presence, AI search, paid search).
2. Review the six-agency shortlist and first-party evidence links.
3. Match boutique specialist versus larger agency to programme complexity and operating rhythm.
4. Demand a joint measurement plan with separate baselines and no double-counted conversions.
5. Compare itemised proposals on the same scope — fee, media, tools and exclusions.
6. Ask every shortlist, including the publisher, the same ownership and first-90-day questions.

By Modi Elnadi, Founder of Integrated.Social. Updated 28 September 2026.

Editorial disclosure: Integrated.Social publishes this guide and is one of the agencies listed. Inclusion requires first-party evidence of a London presence, AI search capability and paid search capability. The six firms appear alphabetically, without paid placement or a quality ranking. “Potential fit” is our interpretation of public positioning, not a verified client endorsement. We have not independently audited agency results or tested each agency's joint delivery.

How were these London agencies selected?

We checked each agency's own website for three inclusion conditions: a London office or presence, a published AI search or AI-aware organic search capability, and a published paid search or Google Ads service. Six firms met this evidence threshold in this review. The shortlist is illustrative, not exhaustive, and omission does not imply a firm lacks expertise.

This standard verifies public claims, not campaign quality. We did not score proprietary platforms, private client contracts, staff experience or fees that the agencies have not disclosed. A buyer should confirm the exact delivery team and current scope in a proposal.

First-party evidence vs directory claims

A directory “AI marketing” category, a starting price in euros or another publisher's roundup does not establish a London AI search and Google Ads service. Prefer the agency's own service and location pages, then ask for named practitioners, current scope and a joint workplan in the proposal.

Why did the original 21-agency list need narrowing?

Several original entries were primarily brand, social, automation, design or workplace-safety businesses with no verified public evidence of both required capabilities. Others were outside London or documented only one side of the brief. A directory's “AI marketing” category and a starting price in euros cannot establish a London AI search and Google Ads service or its fee.

What is the difference between AI search optimisation and Google Ads?

AI search optimisation aims to improve a brand's discoverability and representation in answer-led experiences, including Google AI features and independent assistants. Google Ads pays for eligible ad placements and optimises bids and creative against campaign goals. The work can inform a shared strategy, but their reporting and causal effects differ; one channel's attributed conversion should not automatically be credited to both.

Which six agencies have public evidence of both capabilities?

AccuraCast, Brainlabs, Croud, Delante, Impression and Integrated.Social meet the stated public-evidence threshold. Their service descriptions show different emphases: multilingual PPC, enterprise measurement, integrated search, international SEO/SEM, experimentation and B2B growth. The table links to each agency's own evidence so buyers can check the current offer and request comparable proposals.

“Potential fit” is an editorial inference from each provider's published positioning. It is a shortlist prompt, not a comparative performance score. We found no consistently comparable public starting fees for the combined service and have not inserted third-party directory prices into this table.

What does AccuraCast publicly offer?

AccuraCast publishes an AI search optimisation service covering AEO and GEO, alongside an international paid search service. Its contact page identifies a London office. The multilingual emphasis makes it worth investigating for brands operating across several markets; ask how organic AI visibility and PPC data are actually coordinated.

What does Brainlabs publicly offer?

Brainlabs publishes substantive AI search strategy and paid search analysis, and lists a London office. These show relevant practices but do not by themselves establish the team, fee or integrated deliverables for your account. Request a named cross-channel lead and a shared measurement plan in the proposal.

What does Croud publicly offer?

Croud's SearchAnywhere service describes visibility across conversational AI, search and social, while its UK paid search service addresses campaign execution. It has a London location. Ask which SearchAnywhere insights change paid-search decisions and which outcomes are measured separately to avoid double counting.

What does Delante publicly offer?

Delante explicitly lists AI Search Optimisation (AISO) and Google Ads management, with a London address. That makes the dual scope clear on its own site. Buyers should ask for a joint plan showing how search-query insight, content priorities, conversion tracking and commercial reporting connect across the two disciplines.

What does Impression publicly offer?

Impression says its SEO practice encompasses AI search and publishes a PPC management service that names its London office. Its public material emphasises measurement and experimentation. Ask for an example where an AI-search insight and a paid-search test were evaluated together, including the baseline and decision made.

What does Integrated.Social publicly offer?

Integrated.Social publishes SEO, AEO and GEO and PPC with Performance Max, serving clients from London. Its case studies describe distinct engagements in FinTech paid acquisition, B2B SaaS account-based marketing and multichannel travel. Those outcomes are publisher-reported and should not be presented as a controlled result of combining AI search and Google Ads.

The FinTech case study reports a persona and testing-led registration increase; the B2B SaaS case study illustrates buying-group targeting. Neither is a head-to-head agency comparison. Ask for a scoped measurement plan for your own market and baseline.

How do you choose between a boutique specialist and a larger agency?

Choose according to programme complexity, the people who will do the work and the operating rhythm you need. A specialist may offer direct senior involvement and a narrower scope; a larger agency may offer deeper platform teams and international capacity. Neither model is inherently better. Validate capacity, handoffs, data access and decision-making through the proposed team and workplan.

Our AEO agency selection guide explores specialist evaluation. The agency versus in-house versus hybrid guide helps decide the operating model before seeking proposals.

Which questions should every shortlisted agency answer?

Ask who owns paid search and AI search, how their teams share buyer-question research, what is delivered in the first 90 days and which decisions depend on measured outcomes. Request examples with dates, denominators and limitations. Confirm account ownership, access to raw data, reporting definitions, exit terms and the distinction between agency fees, tools and media spend.

What should a joint measurement plan contain?

A joint plan needs separate baselines for AI-answer visibility, traditional search, paid clicks and business outcomes, plus shared buyer cohorts where possible. Record AI citations and referrals as observations, not direct proof of revenue. Use CRM outcomes, experiments or holdouts when feasible. Agree how the team will avoid counting the same conversion twice.

Can AI search and PPC actually reduce acquisition cost together?

They can inform better decisions together, but savings must be demonstrated rather than assumed. Paid search terms can expose valuable buyer questions for organic pages; AI visibility research can reveal missing comparison and trust content. Test changes against qualified leads, sales and incremental return. A citation does not automatically replace a paid click, and an account-wide CPA movement is not causal proof.

Citations are observations, not revenue proof

Treat AI citations and referral-like signals as visibility observations. Link them to commercial outcomes only when you have shared buyer cohorts, experiments or holdouts. Do not credit the same conversion to both AI search and paid search without an agreed rule for avoiding double counting.

Integrated.Social's organic, paid and agentic AI CPA/LTV framework explains the distinction between observed channel movement and supported commercial conclusions. Its brand PPC incrementality guide shows why apparent paid performance can include demand that existed already.

Should you cut bids when an AI Overview cites your brand?

Do not cut bids solely because an AI Overview mentions the brand. The citation may appear on different queries, vary over time or reach buyers at another stage. Segment by query intent, brand status and device, then test budget changes against incremental conversions or profit. Retain paid coverage where it demonstrably adds profitable demand.

What does a combined AI search and PPC agency cost in London?

There is no reliable single London price for this combined brief. Separate the agency's strategy and delivery fee, advertising spend, data or AI-visibility tools, content production and implementation costs. Ask every shortlisted firm to price the same scope and disclose what is excluded. Directory “from” prices for a broad AI marketing category cannot be compared with a combined retainer.

Separate fee, media and tool lines

Request itemised proposals that split agency fee, Google Ads media, content or development work and third-party tools. Compare exclusions and ownership of accounts and raw data. Do not treat a directory “from” price as the fee for a combined AI search and PPC programme.

For a detailed AEO-only pricing lens, read our UK AEO cost and ROI guide. A combined proposal should explain the incremental cost of adding paid media management and how the programme will be judged by pipeline, revenue or profit, rather than by citation count or clicks alone.

Frequently asked questions about London AI search and PPC agencies

The central buying questions concern which agencies truly provide both disciplines, what integration means in practice, how much to budget and how to judge results. The answers below use public service evidence and a conservative measurement standard. Treat every agency's self-reported result as a case-specific claim and request supporting detail during procurement.

Which London agencies handle both AI search and Google Ads?

This review found public evidence for six: AccuraCast, Brainlabs, Croud, Delante, Impression and Integrated.Social. Each has a London presence and published material covering AI search or AI-aware SEO and paid search. The list is illustrative rather than exhaustive. Confirm current staffing and whether the two practices will work together on your account.

Google Ads pays for eligible ad placements and optimises bids and creative against campaign goals. The work can inform a shared strategy, but their reporting and causal effects differ; one channel's attributed conversion should not automatically be credited to both.

Is AI search optimisation the same as PPC?

No. AI search work addresses discoverability and representation in answer-led systems; PPC buys eligible advertising placements and optimises spend against campaign goals. Both can share buyer research, content and measurement definitions. Their exposure and attribution are different, so a joint dashboard must show each channel separately before assessing their combined commercial effect.

How do you choose between a boutique specialist and a larger agency?

Choose according to programme complexity, the people who will do the work and the operating rhythm you need. A specialist may offer direct senior involvement and a narrower scope; a larger agency may offer deeper platform teams and international capacity. Neither model is inherently better. Validate capacity, handoffs, data access and decision-making through the proposed team and workplan.

Segment by query intent, brand status and device, then test budget changes against incremental conversions or profit. Retain paid coverage where it demonstrably adds profitable demand.

Will AI search visibility let me stop bidding on informational keywords?

An AI citation alone is not enough reason to stop bidding. Check whether the same queries and audiences are covered, how often the citation appears and whether paid clicks create incremental qualified demand. Run a controlled budget test where possible. Retain or move spend according to marginal return, rather than assuming organic and paid exposure are interchangeable.

What does a combined AI search and PPC agency cost in London?

There is no reliable single London price for this combined brief. Separate the agency's strategy and delivery fee, advertising spend, data or AI-visibility tools, content production and implementation costs. Ask every shortlisted firm to price the same scope and disclose what is excluded. Directory “from” prices for a broad AI marketing category cannot be compared with a combined retainer.

What budget do I need for AI search and PPC in London?

Budget comprises agency fees, Google Ads media, content or development work and any third-party tools. The six firms do not publish one directly comparable price for the combined brief. Request itemised proposals for a consistent scope and calculate the maximum sustainable customer acquisition cost from margin and expected customer value before setting media spend.

Can an agency guarantee AI citations or top Google Ads results?

No credible agency can guarantee that a particular assistant will cite a page or that an ad will win a given auction. Both systems vary with query, competition, eligibility and time. Ask for a baseline, test plan, transparent reporting and examples of decisions made from evidence instead of a promised position or fixed citation count.

How should I compare combined AI search and PPC proposals?

Give every agency the same brief: target buyers, markets, budget, existing conversion data and commercial goal. Compare the named team, first-90-day workplan, deliverables, measurement methods, fee exclusions and account ownership. Ask each to diagnose one real search-intent problem and explain how paid and organic work would contribute to its solution.

Does FAQ or Article schema make an agency comparison appear in AI answers?

No. Accurate structured data helps describe visible content, but Google says AI Overviews and AI Mode require no special schema. The stronger factors to control are indexability, useful evidence, clear source links, internal discovery and up-to-date claims. FAQ answers should help the reader first; markup must match what the page actually displays.

Should I choose a London agency or can a UK agency work remotely?

London presence may help with workshops, stakeholder access or procurement, but location alone does not establish performance. A capable remote UK team can manage the same platforms. Compare sector experience, named practitioners, response cadence, data governance and evidence of joint delivery. Choose an operating model that fits your team, not a postcode.

Is Integrated.Social included as the publisher?

Yes. Integrated.Social publishes this guide and is one of the six agencies listed. Inclusion follows the same first-party evidence standard for London presence, AI search capability and paid search capability. The firm appears alphabetically, without paid placement or a quality ranking. “Potential fit” is editorial interpretation of public positioning, not a verified client endorsement.

Sources, review method and next step

Every agency entry links to its own service and London evidence. This review was conducted on 28 September 2026 and should be refreshed when providers change their offers. We did not use directory category prices as agency fees or independently verify client performance. See Google's AI features guidance for technical context.

If your brief involves B2B qualified pipeline, compare Integrated.Social's AI search scope and PPC scope against the other five providers, then request a diagnostic conversation. Ask every agency, including us, to explain its measurement assumptions and first-90-day decisions.
