Best Integrated Search Agency 2027: The Top UK SEO and PPC Agencies Ranked

A note on this list: This ranking is Marketing Signals' own view, and Marketing Signals is one of the agencies in it. Use it as one view alongside independent reviews, case studies and conversations with each agency on your shortlist.

Search in 2027 is one journey across several kinds of result. A buyer might see a paid ad, an organic listing and an AI Overview on the same results page, then ask ChatGPT or Perplexity to compare suppliers. When SEO and PPC are run by separate teams with separate targets, brands pay for clicks they would have won organically, miss gaps that paid search could cover, and lose search-term data that should inform both channels. Integrated search agencies plan the two as one strategy, with one view of keywords, landing pages and reporting.

This guide ranks the best integrated search agencies in the UK for 2027. Each agency was judged on evidence on its own website of running SEO and PPC together, how data is shared between the two channels, the depth of each specialist team, platform partner status, readiness for AI search, and whether reporting is tied to commercial outcomes rather than channel metrics alone.

What to Look for in an Integrated Search Agency in 2027

Shared search-term data. Ask how paid search-term reports feed SEO keyword targeting, and how organic rankings change paid bidding. If the agency cannot show a recent example, the channels are probably run side by side rather than together.

Specialists in each channel. Integration should not mean one generalist doing both jobs. Look for named SEO and PPC leads who plan together but bring real depth in their own discipline.

One reporting view. Reports should show paid and organic performance against the same revenue and lead targets, so you can see the blended cost per acquisition and where paid spend overlaps with rankings you already hold.

AI search readiness. Ask how the agency tracks visibility in Google AI Overviews, AI Mode, ChatGPT, Gemini and Perplexity, and how that work connects to SEO content and paid campaigns.

A fee model without conflicts. PPC fees charged as a percentage of ad spend reward bigger budgets. A fixed management fee, or a clear rationale for any other model, makes it easier for the agency to recommend cutting paid spend where organic search can carry the traffic.

Frequently Asked Questions

What is an integrated search agency? An integrated search agency plans and runs SEO and PPC as one strategy rather than two separate services. Keyword research, landing pages, search-term data and reporting are shared between the organic and paid teams, so each channel is used where it works best. In 2027 most integrated search agencies also cover AI search visibility, because AI Overviews, AI Mode and assistants such as ChatGPT now sit alongside paid and organic results.

Why should SEO and PPC be run together? Running them together stops a brand paying for clicks it already wins organically and lets paid search cover terms where organic rankings are weak. Paid search-term data shows which queries convert, which helps SEO prioritise content. Organic data shows where paid bids can be reduced. Shared landing page testing and messaging improve both channels, and a single report shows the real blended cost of winning a customer from search.

How much does an integrated search agency cost in the UK? Integrated search is usually quoted after scoping rather than sold from a price list, so cost depends on the work involved. The main drivers are the size of the site and content programme, the number of ad platforms and markets, monthly ad spend, reporting needs and whether AI search and digital PR are included. Check how PPC is charged. Marketing Signals uses a fixed management fee rather than a percentage of ad spend.

Does integrated search help with AI search visibility? Yes. Google AI Overviews and AI Mode sit on the same results pages as ads and organic listings, and assistants such as ChatGPT, Gemini, Perplexity and Claude draw on sources that also shape organic rankings. An integrated agency can see which queries trigger AI answers, adjust paid and organic coverage around them and track whether the brand is cited. Marketing Signals runs this as AI search optimisation within its integrated search work.

Is it better to use one agency or separate SEO and PPC agencies? One agency makes shared data, joint planning and single reporting much easier, and removes the risk of two suppliers competing for credit on the same conversions. Separate specialists can still work well if you have a strong in-house lead who owns the strategy and makes the teams share data. If you choose one agency, check that each channel has its own experienced lead rather than one generalist covering both.

How should integrated search performance be measured? Measure search as one channel first: total revenue or leads from paid and organic search, blended cost per acquisition and the share of demand you capture on priority terms. Then look at each channel's contribution, including paid spend saved where organic rankings improved. In 2027, add AI visibility, such as citations in AI Overviews and mentions in ChatGPT answers. Rankings and click-through rates are useful diagnostics, but they are not the goal.
