Your cookie banner may be hiding half the story
Under UK privacy rules, visitors must agree before most advertising cookies are set. Many of them click “Reject”, and unless consent mode is set up properly, their conversions never reach Google Ads. The account then looks worse than it is, and automated bidding learns from a partial picture.
London clicks are also among the most expensive in the UK, so loose keywords and weak landing pages cost more here than anywhere else in the country. We fix the tracking first, then remove the waste, so each decision rests on real results.
What we fix in your Google Ads account
Conversions lost to the cookie banner
A banner that blocks tags instead of passing consent signals leaves Google blind. We set up consent mode and enhanced conversions, so modelled and consented results are both counted within the rules.
Financial ads that risk the rules
Financial promotions must be fair, clear and not misleading, and Google asks many financial advertisers to prove FCA authorisation. We check ads and landing pages before they go live.
High cost per lead
When each enquiry costs too much, we remove the searches that never convert, tighten your location and audience targeting, and move budget to the campaigns that are performing.
Wasted spend on the wrong searches
Broad keywords and loose match types drain budgets quickly. We review your search terms report every week and build negative keyword lists that stop irrelevant traffic.
Brand campaigns taking the credit
People searching for your company name were already coming to you. We report branded and non-branded results separately, so you can see what is genuinely new business.
Reports full of clicks, not revenue
Your report shows cost per qualified lead, cost per sale and return on ad spend, because impressions and clicks on their own don’t pay the bills.

Why London businesses choose Oneskai as their Google Ads agency
Tracking built for UK privacy law
We treat consent as part of the measurement set-up, not an afterthought for the legal team. Your banner, tags and Google Ads settings are configured to work together.
We measure revenue, not just enquiries
Many agencies stop counting at the form submission. We connect your advertising to your CRM or online store, so you can see which campaigns actually generated revenue.
Paid search and SEO in one plan
We also run SEO in London, so we can stop paying for clicks you would get for free and use ads to cover the searches you can’t rank for yet.
A fee that doesn’t grow with your spend
You pay a flat monthly management fee, never a percentage of your media budget. Your Google Ads account is always yours, and so is its complete history.

Grow what works
Budget moves to the campaigns that bring in customers, and you get a clear monthly report and a review call.
Most accounts cut the obvious waste within a few weeks, but reliable results usually take about three months. That is how long Google needs to learn, and how long we need to collect enough data to make good decisions.

Targeting London and beyond
We can target Greater London, particular boroughs, the City and Canary Wharf, the commuter belt, or the whole UK. We work with London businesses remotely, with video calls whenever you need them.
How much does Google Ads management cost in London?
Our management fee is a flat monthly amount, based on how many campaigns and channels we run rather than on how much you spend. We quote it in writing after the audit, before you commit to anything.
You pay Google directly for your clicks, and we never add a markup to your media spend.
If your budget is too small to give Google’s bidding enough conversion data to learn from, we will tell you so in the audit rather than take on the account.

Google Ads and PPC questions from London businesses
What does a PPC agency do?
A PPC agency plans, builds and manages your paid ads, mostly on Google. That covers keyword research, ad writing, bidding, conversion tracking and landing pages, with the goal of winning more customers for less ad spend.
How much does Google Ads management cost in London?
London agencies usually charge either a flat monthly fee or a percentage of ad spend, on top of what you pay Google. We charge a flat fee based on the campaigns and channels we manage, and we quote it after the free audit.
Does our cookie banner affect Google Ads results?
Yes. When visitors reject cookies, their conversions are not recorded in the usual way. Consent mode lets Google model some of those results without breaking UK privacy law, but only if the banner and tags are set up to pass the right signals.
Can financial services firms advertise on Google in the UK?
Yes, but Google asks many financial advertisers to verify that they are authorised by the FCA, and the ads themselves must follow financial promotion rules. We check both before a campaign goes live.
How much should a London business spend on Google Ads?
Enough for Google to learn from, which usually means at least 30 to 50 conversions a month. London clicks often cost more than elsewhere in the UK, so we estimate your budget from real search data in the audit.
What is the difference between PPC and SEM?
Search engine marketing (SEM) usually means paid ads on search engines like Google and Bing. PPC, or pay-per-click, is the pricing model where you pay for each click, and it also covers paid social and display. On this page they mean the same work: managing your Google and Microsoft search ads.
Should I hire a Google Ads agency or a freelancer?
A freelancer can suit one simple campaign. An agency makes more sense when you also need tracking, landing pages and reporting handled, or someone to cover when one person is away. Either way, ask who will actually run your account, and make sure the account is in your name.
How long does PPC take to work?
Ads can start showing within a day. Cutting the obvious waste usually takes a few weeks, and stable, reliable results usually take around three months while Google learns from your data.
Can you take over our existing Google Ads account?
Yes. We keep your account and its history, and we fix what is there rather than starting from scratch, unless starting fresh is genuinely the better option.
Do I own my Google Ads account?
Yes. The account, the data and the history all stay in your name, so if we ever part ways, you keep everything.
Do you take a percentage of ad spend?
No, we charge a flat management fee. A percentage model rewards an agency for recommending that you spend more, and we would rather our advice had no such pull.
How do you measure PPC success?
We track cost per qualified lead, cost per sale and return on ad spend. Branded and non-branded results are reported separately, and we connect to your CRM or online store wherever we can.
Should one agency run both our Google Ads and SEO?
It usually helps. A single team can stop you paying for clicks you would already win organically, and use ads to cover the gaps while your SEO is still developing.
