Google Ads Agency London
Google Ads agency London businesses hire to fix wasted spend: an account audit, conversion tracking, a restructure and monthly reporting. Book a call to talk through your account.
Last updated October 12, 2026
Blackstone Media is the Google Ads agency London businesses hire when their account is burning budget without producing enquiries. We run Google Search, Shopping, Performance Max, and Display campaigns, the full paid search stack that makes us a PPC agency as much as a Google Ads specialist, with a single focus: profitable return on ad spend.
London Google Ads are expensive to run badly. Cost-per-click for commercial keywords in London can be high, particularly in legal, financial services, healthcare, and home improvement, and you can check current estimates for your own sector in Google Keyword Planner. A poorly structured campaign at those prices does not underperform. It bleeds.
Blackstone Media charges from £600 a month to manage a Google Ads account (typically £600 to £2,000), excluding ad spend. Where an account is being rebuilt from scratch there is a one-off fee from £500 (typically £500 to £1,500) for the account build, tracking setup and targeting strategy. Running two or more ad platforms together is from £900 a month (typically £900 to £3,000). Ad spend is billed separately from the management fee and is paid to the ad platform. All figures exclude VAT.
We audit every new account before we change anything. In the accounts we audit, we typically find 30 to 60 percent of spend going to keywords, match types, or placements that will never convert. We stop that first.
What Is Wrong With Most London Google Ads Accounts?
- •Broad match keywords without negative keyword lists: budget consumed by irrelevant searches
- •Search and Display in the same campaign: each channel's data muddies the other's
- •Missing or broken conversion tracking: Smart Bidding optimising for nothing
- •Weak ad relevance, expected CTR or landing page experience: often paying more per click than necessary
- •Performance Max with no asset testing: Google's automation working without direction
- •No retargeting: prospecting only, abandoning visitors who already showed intent
- •Single ad per ad group: no testing, no improvement, creative fatigue with no replacement
What Does Our Google Ads Management Include?
- •Full account audit and restructure: campaigns rebuilt around buying intent
- •Conversion tracking setup: Google Tag Manager, GA4 key events, call tracking, form completions
- •Negative keyword management: reviewed regularly to prevent budget waste
- •Ad copy testing: multiple RSA variants per ad group tested against CTR and conversion rate
- •Quality Score optimisation: landing page experience, ad relevance, and expected CTR improved systematically
- •Bid strategy management: Smart Bidding configured correctly once conversion data is sufficient
- •Shopping and Performance Max: feed optimisation, asset testing, and exclusion lists
- •Monthly reporting: ROAS, CPA, impression share, and wasted spend reduction reported clearly
Why Choose Blackstone as Your PPC Agency London Businesses Trust?
Google Ads is one channel inside PPC, not a synonym for it. A proper PPC agency in London manages the full paid search and shopping stack, not just Search campaigns wearing a Google Ads label. Blackstone runs Search, Shopping, Performance Max, Display, and YouTube Ads under one strategy, because siloing these channels away from each other is one common cause of the 30 to 60 percent of wasted spend we typically find in the accounts we audit.
Most agencies that call themselves a "Google Ads agency" are describing the platform, not the discipline. PPC (pay-per-click) is the broader term that also covers Microsoft Ads and paid social. When you hire a PPC agency in London that treats every paid channel as connected, budget can move to whichever channel is converting best, instead of staying locked in one platform because that is the only one the agency knows how to run.
- •Cross-channel budget allocation: shifting spend toward the channel producing the lowest cost per acquisition, not the channel the retainer was originally scoped around
- •Shared learning: what we find about converting audiences and messages on one channel informs targeting and creative on the others, instead of each channel starting from zero
- •Single reporting view: one report covering blended CPA and ROAS across every paid channel, so budget decisions are made on the full picture, not one platform in isolation
- •One team: a specialist team across the paid channels, working to one plan, rather than separate suppliers optimising against each other's budget
London Sectors Google Ads Can Serve
- •Legal services: solicitors, immigration lawyers, family law, employment law
- •Financial services: accountants, financial advisers, mortgage brokers
- •Home services: builders, plumbers, electricians, roofers
- •Healthcare: private clinics, dental practices, physiotherapy, cosmetic procedures
- •IT and technology: IT support companies, MSPs, cybersecurity firms
- •Professional services: recruitment agencies, consultancies, training providers
- •Ecommerce: London-based retailers running Shopping and Performance Max

Frequently Asked Questions
Can you take over an existing Google Ads account?
Yes. We audit the account, identify the structural problems, and rebuild or optimise. We do not start from scratch unless the account history is so problematic that a clean rebuild is faster.
What is the difference between a Google Ads agency and a PPC agency?
In practice, very little at Blackstone. PPC is the umbrella term covering Google Ads, Microsoft Ads, and paid social advertising; a "Google Ads agency" is usually a PPC specialist working primarily inside Google's platforms. We manage the full PPC stack, Google Search, Shopping, Performance Max, Display, and Meta Ads, for clients who want one team running paid media rather than two or three agencies competing over attribution.
Do you manage Shopping and Performance Max campaigns?
Yes. For ecommerce clients we manage Google Shopping feeds, Performance Max, and Search in an integrated strategy. Feed quality is often a major lever in Shopping performance.
What budget do I need to run Google Ads profitably in London?
For most competitive London sectors, you need enough monthly ad spend for Smart Bidding to gather sufficient conversion signals. Below that threshold, campaigns stay in extended learning phases. We advise on the right starting budget for your specific sector during the initial consultation.
How Do You Evaluate a Google Ads Agency London Businesses Can Trust?
Most London businesses hiring a Google Ads agency make the same mistake: they evaluate based on the pitch, not the track record. A good pitch deck from a mediocre agency wins clients every day. Here is what to ask.
- •Ask to see a real account audit from a similar client: not a case study they wrote, an actual audit showing what they found and what they fixed. This tells you whether they know what to look for.
- •Ask about their conversion tracking setup process: an agency that does not verify conversion tracking before changing bids may not understand how Smart Bidding learns.
- •Ask how often the accounts they take over have broken tracking: the honest answer is often. An agency that claims otherwise may not be auditing thoroughly enough.
- •Ask how they manage Performance Max: this is where agency quality diverges most clearly. Strong agencies configure it with audience signals, asset testing, and exclusion lists. Weak agencies leave it on default and call it 'automated'.
- •Ask how they diagnose and improve ad relevance, expected CTR and landing page experience: an agency with no method for these may be paying more per click than necessary on the accounts they manage.
- •Ask what they report on beyond ROAS: cost per lead, cost per acquisition, impression share lost to budget, impression share lost to rank. If the answers are vague, the account management is vague.
What Do Profitable Google Ads Results Look Like in London?
Profitability in Google Ads is not about cost per click. Cost per click is an input. What matters is cost per acquired customer relative to your margin on that customer. A £40 cost per click can be profitable if enough of those clicks become £4,000 sales, while a £2 cost per click can lose money if too few become £200 sales.
CPCs in competitive London sectors such as legal services, financial advice, healthcare, home improvement, and IT support can be high. These are not necessarily overpriced. They reflect the commercial value of the buyer intent behind those searches. Managing to a cost per acquisition, not a cost per click, is the most reliable way to run campaigns profitably at these rates.
- •Define your target CPA before the campaign launches: what can you afford to pay for each enquiry or sale given your margins? This number drives every bid and budget decision.
- •Separate brand and non-brand campaigns: brand keyword costs are usually lower and conversion rates higher. Mixing them with non-brand terms distorts performance data.
- •Run search impression share reporting: if you are losing significant impression share to budget, you are underfunding winning campaigns. If you are losing impression share to rank, your ads are ranking below competitors, which can reflect bids, ad relevance, expected CTR or landing page experience.
- •Track lead-to-close rate from paid traffic: a high volume of leads that never convert is a landing page or lead qualification problem, not a Google Ads problem.
Should You Run Google Ads and SEO Together in London?
Google Ads and SEO are not alternatives. They serve different parts of the buyer journey and different timelines. Google Ads generates leads today. SEO builds over months rather than days, and the gains compound. Running both simultaneously means you are never entirely dependent on either channel.
The data from your Google Ads account is also the best source of keyword intelligence for your SEO programme. The keywords that produce the best conversion rates in paid search are the ones worth investing months of content and link building work to rank for organically. Blackstone runs both as a connected strategy for clients where that approach makes sense.
How do London CPCs compare to the rest of the UK?
London CPCs can be higher than equivalent regional searches for some service-based keywords, often reflecting more commercial competition and higher average deal values. The higher CPC is easier to justify when the buyer intent and average order value are also higher, which can be the case for London professional services. Check your own sector in Google Keyword Planner.
What is a realistic ROAS for London Google Ads?
Target ROAS varies significantly by sector and product margin. An ecommerce business with a 40 percent gross margin needs a ROAS of at least 2.5x just to break even on ad spend, before management fees. Service businesses measure cost per lead rather than ROAS. A sensible cost per qualified lead depends on average deal value and conversion rate, so we set a target CPA from your own margins rather than from a generic benchmark.
Do you work with Google Merchant Center and Shopping campaigns?
Yes. For ecommerce clients we manage the full Google Shopping stack: Merchant Center feed optimisation, Performance Max configuration, Standard Shopping campaigns for high-value SKUs, and Dynamic Remarketing for returning visitors. Feed quality is often a bigger lever in Shopping performance than campaign bidding.
How long before Google Ads produces leads?
A correctly structured Google Search campaign with verified conversion tracking can start producing enquiries once it is live, depending on budget, account history and audience. The first period is a data collection phase: search term reports reviewed regularly, negatives added, bid strategy set to manual or target CPA with sufficient data. Performance can begin to stabilise as Smart Bidding accumulates conversion history, though results are not guaranteed.
What Is the Hidden Cost Driver Behind Quality Score in London PPC?
Quality Score is Google's assessment of how relevant your ad and landing page are to the keyword being searched. It is reported on a scale of 1 to 10 at keyword level. Google describes it as a diagnostic tool and states it is not an input in the ad auction, but the three things behind it (expected CTR, ad relevance and landing page experience) are the same things that influence how your ads perform and what you pay. In London, where CPCs are already high, weak performance on those three is costly.
Quality Score has three components: expected click-through rate (how often your ad is clicked relative to how often it is shown), ad relevance (how closely your ad matches the intent behind the search), and landing page experience (how useful and relevant your landing page is to someone who clicked the ad). Each can be improved systematically, and any of them can be rated below average on your primary keywords.
- •Expected CTR improvement: write ad copy that matches the specific query intent, not generic brand messaging. Test headline 1 as the keyword match, headline 2 as the key benefit, headline 3 as a differentiator or CTA.
- •Ad relevance improvement: ad copy should contain the exact keyword or close variant in at least one headline. Ad groups should be tightly themed so one set of ads covers a specific query intent.
- •Landing page experience improvement: the landing page headline should directly reflect the ad headline. If the ad promises a fixed-price quote, the landing page should open with that offer. Every mismatch between ad and page can hurt landing page experience.
- •Quality Score monitoring: tracked regularly per keyword alongside impression share data to identify where wasted spend can be recovered by improving relevance.
Where Do London Google Ads Budgets Go to Waste?
Wasted spend in Google Ads is not a minor inefficiency. In the accounts we audit, we typically find 30 to 60 percent of spend going to waste. Identifying and stopping it is always the first action on a new account, before any bid increases or budget additions.
- •Search terms report: the single most important weekly task in any Google Ads account. Every week, the search terms report reveals what searches triggered your ads. Searches with no conversion potential get added to the negative keyword list.
- •Broad match without controls: broad match keywords in London sectors match searches that are semantically distant from your offering. Without a thorough negative keyword list updated weekly, broad match bleeds budget continuously.
- •Display Network waste: search campaigns that include Google's Display Network serve ads on websites instead of search results, often at lower conversion rates. These should be separated into standalone campaigns.
- •Location targeting errors: ads showing outside the specific London areas where you serve clients. Geographic bid adjustments or targeted location settings prevent budget leaving the relevant area.
- •Time-of-day waste: if your business does not take enquiries on weekends and your ads run 24/7, you are paying for clicks that will never convert. Ad scheduling aligns spend with when conversions occur.
Where Are London Google Ads Conversions Won or Lost?
A Google Ads campaign that drives traffic to your homepage is not a campaign. It is paid traffic to a page not designed to convert the specific intent behind the ad. A solicitor running ads for 'employment law advice London' sending clicks to a generic legal services homepage will typically convert worse than the same ads sending clicks to a dedicated employment law landing page.
Landing page design for paid search has specific requirements that differ from general web design. The page exists for one purpose: to convert a visitor who arrived with a specific search intent. Everything else is a distraction from that goal.
- •Headline match: the landing page headline must reflect the ad promise. Mismatches between ad and page create distrust and increase bounce rate.
- •Single call to action: one ask per page. Multiple CTAs split attention and reduce completion rate on all of them.
- •Social proof above the fold: testimonials, client logos, or trust marks visible before the visitor scrolls.
- •Form length: three to four fields maximum for first contact. Every additional field can reduce submission rate.
- •Click-to-call on mobile: a large share of searches happen on mobile. A phone number formatted as a clickable link converts mobile visitors who will not complete a form.
- •Page speed: a slow-loading landing page loses paid traffic before visitors see the offer. Paid clicks are expensive. Slow landing pages waste them.
