A buyer's guide to PPC agency tools and providers

What to take away

Most PPC procurement goes wrong at the first step. Teams gather platform demos, rank features, and negotiate a price, then discover months later that nobody in the business knows how to operate the thing they bought. The tool was never the hard part.

This guide sets out how to buy PPC agency tools and providers as one decision rather than two. It runs from defining the requirement through a scored comparison to planning implementation. It covers search, social, video and programmatic, because a modern paid search account rarely runs in isolation.

Start with the operating model

Before any shortlist, write down who will do the work. There are three common models, and they are not interchangeable.

A tool-only purchase means your in-house team holds the platform licence and runs campaigns. A managed service means an agency or consultancy runs campaigns on platforms it already licenses. A hybrid means the agency operates some channels while your team keeps direct control of others, usually brand search or a regulated product line.

The choice drives everything downstream. Tool-only deals need internal capacity, governance and someone senior enough to own performance. Managed deals need clear service levels and a defined reporting pack. Hybrid deals need a written boundary, or the two sides will duplicate work and blame each other for gaps.

Write the model down in one paragraph. If the paragraph needs a diagram, the model is not settled yet.

Requirements before demos

A requirements document is not bureaucracy; it is the only defence against a demo that answers questions you did not ask. Keep it to two pages.

Cover the channels in scope, the reporting the business already consumes, the approval workflow for budget changes, and any regulatory constraints that apply to your sector. Add the practical items that get forgotten: how many user seats, which currencies, which markets, and whether historical data must migrate.

State your tolerance for automation explicitly. Some finance teams want every bid change logged and reversible. Others are content to let a platform reallocate budget within a daily cap. Both are defensible, but only one will pass an audit.

Finally, list the reporting outputs by name. If the board sees a weekly spend and conversion summary, that summary is a requirement, not a nice-to-have. Turning that list into a scored checklist is the next step, and our guide to PPC agencies software selection in England explains how to run it without letting the shortlist drift.

The supplier categories

Providers in this market fall into four broad groups, and most accounts end up using more than one. The named tools below are the ones UK teams most often shortlist.

Search platforms and their management tools. Google Ads and Microsoft Advertising remain the core of paid search, and Microsoft Advertising's solutions pages set out how search, audience and native placements sit together for advertisers. Third-party bid managers include Marin Software, Skai and Acquisio.

Marin supports cross-channel bidding across Google, Microsoft and Amazon, with pricing on request. Skai covers search, social and retail media for large advertisers, also priced on request. Acquisio provides bid and budget management, now part of Web.com, with pricing on request. Google Ads Editor and Microsoft Advertising Editor are free desktop tools for bulk changes.

Social and video platforms. Meta, LinkedIn and TikTok each run their own buying interfaces and measurement. LinkedIn Campaign Manager is the interface where B2B campaigns are built and managed, which matters if you are buying demand alongside search. Meta Ads Manager and TikTok Ads Manager are the equivalent interfaces for those platforms.

Automation and API layers. Scripts, third-party bid managers and custom builds sit on top of the platforms. Optmyzr offers rule-based automation, auditing and budget pacing, with subscription tiers published on its site. Adalysis provides continuous account audits and ad testing, also on published subscription tiers. The Google Ads API documentation explains how programmatic changes to campaigns, budgets and reporting are made, and it is the reference point for any build you commission.

Programmatic and display partners. Where paid search sits next to display, the buying mechanics differ enough that a separate supplier is often involved. Display and Video 360 is Google's demand-side platform for programmatic display and video, with pricing on request.

The Trade Desk is an independent demand-side platform with a self-serve model and a platform fee. Criteo focuses on retail media and retargeting, with managed service pricing. The IAB UK guide to programmatic covers the trading models and terminology you will meet in those conversations.

Scoring rubric

Use one table for every provider, and agree the weights before the first demo. A worked example is below; adjust the weights to your own priorities.

Score each line from one to five, multiply by the weight, and total. The number matters less than the discipline of scoring every provider on the same lines.

Two lines deserve special treatment. Data ownership and access is a pass or fail item: if the provider will not let you hold the accounts or export your own data, stop. Exit terms are the second test. A provider that cannot describe how a handover works has probably not done many.

Comparing suppliers fairly

Shortlists drift. A provider performs well in a demo, and the criteria are quietly rewritten to accommodate it. The remedy is a fixed scorecard, completed by at least two people independently, then compared.

Ask every provider the same questions in the same order, and put the answers in writing. Pricing models vary enough that a like-for-like comparison needs a defined scope: same channels, same markets, same reporting, same contract length. Our guide to PPC agencies supplier comparison in England sets out how to normalise quotes before you rank them.

For managed services, UK teams compare Brainlabs, Croud, Jellyfish, Journey Further and Impression. Brainlabs is an independent UK agency with London and US offices. Croud runs nearshore teams for paid search and programmatic. Jellyfish sits in Brandtech Group and works globally.

Journey Further is a UK performance agency for search and social. Impression covers PPC, SEO and digital PR. Each quotes on request, usually as a retainer plus a percentage of spend.

Pilot where you can. A paid pilot on one channel or one market for a fixed period is often the cheapest way to test whether the working relationship holds up. Agree in advance what the pilot must demonstrate, and what happens at the end of it.

Platform-specific questions

Generic questions produce generic answers. Add a few that only make sense for the platform under discussion.

For search, ask how brand and non-brand are separated in reporting, and how negative keyword lists are maintained across accounts. Ask what happens to conversion tracking if a tag is blocked.

For video, ask which formats suit the objective in question, and how view-through conversions are treated. YouTube's guidance on video ad formats is the reference for what each format can and cannot do, and it is worth reading before you accept a media plan.

For programmatic, ask which inventory sources are used, what brand safety controls apply, and how fees are disclosed. Ask the provider to explain its supply path in plain terms, and treat an evasive answer as a finding in itself.

Due diligence on the provider

Checks here are mundane and worth doing. Confirm the legal entity, then look it up on the Companies House register to check filing history and any change of name. Ask for the last two years of audited accounts if the contract value justifies it.

Confirm who actually holds the ad accounts. Best practice is that the client owns the accounts, the provider gets access, and the access is revoked when the relationship ends. If the provider insists on holding accounts in its own name, price the exit before you sign.

The same applies to data. Ask what happens to historical performance data at the end of the contract, in what format it is returned, and how long it is retained. Our checklist on PPC agencies vendor due diligence in England covers the documents to request and the answers that should stop a deal.

Where personal data is processed, the provider is likely acting as a processor, and the contract needs a data processing agreement. The ICO publishes guidance on controller and processor roles that is worth reading before you negotiate that clause.

Commercial terms to watch

Percentage-of-spend fees remain common in paid search, and they create an obvious tension: the fee rises when spend rises, whether or not performance improves. If you accept a percentage model, pair it with a performance element or a spend band that reduces the rate at higher volumes.

Watch for platform costs passed through at cost plus a margin. Ask for the pass-through rate in writing. Check whether the fee covers strategy, buying and reporting, or whether reporting is billed separately.

Notice periods matter more than headline price. Three months is common; twelve months is a commitment. Ask what happens if you want to reduce scope partway through, and whether unused platform licences can be transferred.

Implementation and handover

A signed contract is the start of the risky period, not the end. Implementation typically involves account access, tracking, data migration, naming conventions and a first reporting cycle. Each of those can slip.

Build a written plan with dates and owners, and hold a weekly call until the first full reporting cycle is complete. Our guide to PPC agencies tool implementation in England covers the sequence that avoids the usual stalls, including the tracking checks that should happen before any spend goes live.

Insist on training for the people who will use the platform. Recorded sessions and written documentation are worth more than a single walkthrough. If the provider runs the account, your team still needs enough access to verify the numbers.

Set a review point at 90 days. At that meeting, compare actual performance against the criteria you scored in procurement. If the platform is not being used as promised, raise it then rather than at renewal.

Budgeting for the whole cost

Subscription or retainer is rarely the largest number. Add implementation, tracking work, training, and internal time for management and review. A tool that saves an hour a week but needs three hours of upkeep is not a saving.

For example, a team paying £400 a month for a bid management platform, plus £2,000 setup, has a first-year cost well above the headline rate. Illustrative figures only, but the shape of the calculation is what matters.

Ask each provider to price the same scope so the totals are comparable. Where a provider cannot, mark the quote as incomplete rather than estimating on its behalf.

Channel mix and the 2027 question

The mix is shifting. Search remains the workhorse, but social, video and retail media now take a larger share of many budgets, and each brings its own buying interface and measurement quirks. A provider that knows only one platform will struggle as the mix changes.

Automation is the other direction of travel. Bid management, budget pacing and creative testing are increasingly handled by platform features or API builds rather than manual work. That raises the value of governance: change logs, approval steps and the ability to explain why a decision was made.

Plan for a review each year. Contracts, platform features and pricing all move, and a supplier that was right two years ago may not be right now. Our outlook on PPC agencies trends and outlook for England in 2027 sets out the shifts worth tracking before you renew.

Common questions

Do we need a tool and an agency?

Not necessarily. A capable in-house team can license a platform directly and skip the agency retainer, while a small team with no paid search experience may be better served by a managed service. The deciding factor is internal capacity, not budget size.

How long should a PPC contract run?

Twelve months is common for managed services, with three months' notice. Shorter initial terms of six months are reasonable for a pilot, provided both sides agree what the pilot must demonstrate before it is extended.

Who should own the ad accounts?

The client should. You keep the accounts in your name, grant the provider access, and revoke it at the end of the contract. This keeps historical data and conversion tracking under your control and makes switching far cheaper.

What should we check first in due diligence?

Company status and filing history, who holds the accounts, how data is returned on exit, and whether a data processing agreement is needed. Any provider that cannot answer those four questions clearly should not reach the shortlist.
