How we vet every listicle
Every agency featured on Web Tonic passes our 84-point editorial review before a single listicle goes live. This is how we vet each pick:
Verified client outcomes: We require real case studies with measurable KPIs — revenue, ROAS, CPA, retention — tied to the exact category being ranked. No cherry-picked wins, no unverifiable numbers.
Independent reputation: We cross-check Clutch, Google, G2, and Trustpilot ratings, and screen for review-bombing or suspicious patterns. Only operators with a consistent, verifiable track record make the cut.
Beyond that, every listing goes through a quarterly re-audit. We check 84 criteria across 6 pillars to make sure it still holds up — here are some of the checks we run:
A Google Ads management agency runs a business's paid advertising on Google: it chooses the searches worth bidding on, builds Search, Shopping and Performance Max campaigns, writes the ads, manages bids and budgets, and measures which clicks become enquiries or sales.
We kept only firms whose own site sells Google Ads or PPC management, then checked each address, client claim and price by hand. All ten are Cardiff-based and nine print a CF postcode; three name a client we verified, and two publish a price, one of them for Google Ads.
What does a Google Ads management agency in Cardiff actually do?
It runs paid campaigns on Google Search, Shopping, YouTube and Performance Max: keyword research, campaign builds, ad copy, bidding, conversion tracking and reports on cost per lead or sale. Ten external Cardiff firms cleared our checks, and all ten are based in the city.

Frequently Asked Questions
How should I choose between these Cardiff Google Ads agencies?
Start with ownership and measurement. A good Cardiff partner builds the Google Ads account in your name, sets up conversion tracking for calls, forms and sales before spending anything, and shares the search terms report rather than a summary slide. Ask who writes the ads, who adds negative keywords and how often bids and budgets are reviewed. Jos Davies works as an independent paid-search consultant, ThisIsUs.Digital leads with PPC and Amazon advertising, and the others sell Google Ads beside web, brand or SEO work.
What does Google Ads management cost in Cardiff?
Two of the ten external firms print a figure. Webspection publishes Google Ads management from GBP £750 plus VAT a month, after a set-up rate of GBP £1,000 plus VAT for the first three months, regardless of ad spend. True SEO Consultants publishes SEO plans from GBP £399 a month and quotes paid search separately. The other eight quote to scope. Ask whether a fee is flat or tied to spend, the minimum term and what reporting is included.
Is Google Ads management different from SEO or social ads?
Google Ads buys visibility the moment a campaign goes live and stops when spend stops; SEO earns unpaid rankings slowly; Meta and other paid social platforms reach people who are not searching yet. Most Cardiff agencies here sell all three, which helps when keyword data and landing pages are shared. Omni SEO and True SEO Consultants lead with organic search, while Pxa Marketing also runs Meta and LinkedIn campaigns. A proposal should still price the management fee, the ad budget and any landing-page work as separate lines, so you can judge each one.
How long does Google Ads take to show results?
A new or rebuilt account usually needs two to four weeks for Smart Bidding to learn from real conversions, and two to three months of clean data before cost per lead settles. A Cardiff venue or local service firm bidding on nearby searches usually settles faster than a national insurer or retailer competing on expensive terms. Be wary of any agency that promises a fixed number of leads before seeing your tracking. A credible plan names the first month's fixes, the testing schedule and the metrics reported each month.
Should I hire a Cardiff agency or one based elsewhere?
Cardiff has a compact local bench: every external firm here works from the city, from Greyfriars Road and Church Street in the centre to Cathedral Road, Taff Embankment, Fitzalan Road, Bute Street, Adam Street and Llandaff. ThisIsUs.Digital gives only Cardiff Bay as its location. A local team knows South Wales demand and can meet in person, and WCS Agency runs its own Cardiff Life publications, but account ownership, tracking and reporting matter more than the postcode.
Choosing a Google Ads Management Agency in Cardiff
All ten external firms are based in Cardiff, so the choice comes down to the kind of team: an independent consultant, a PPC-led agency or a studio that sells Google Ads beside web, brand and SEO work.
Three name a client we could verify, and one prints a Google Ads fee. Ask each firm for one documented account in your sector, with the starting cost per lead and what changed. A single verified result tells you more than a long list of logos.
Ownership comes first. The Google Ads account, analytics and conversion tracking should be created in your name, with the search terms report shared every month rather than summarised.
Finally, ask who runs the account day to day and how often it is reviewed. If you want Google Ads, paid social and the wider growth plan answerable to one team, read our latest analysis or see how we work in Cardiff.
