How Much Should You Spend on Google Ads per Day?
If you’ve ever typed “how much should I spend on Google Ads per day” into Google, you’re probably hoping for a straight answer, something like “£10 a day” or “£50 a day”, and then you can crack on.
The honest answer is, it depends, but not in a useless way.
Daily budget only makes sense once you know two things: what you’re trying to achieve, and roughly how much it costs to get in front of the right people in your market. Because £50 a day can be plenty in one industry, and basically pointless in another.
So in this post, I’m going to help you choose a realistic Google Ads daily budget, based on your goals, your likely cost per click, and the type of campaign you’re running, search, remarketing, YouTube, display, the lot.
First, a quick note about what “per day” actually means in Google Ads
Google Ads uses an average daily budget, not a strict daily cap.
That means, on some days it might spend less, on other days it might spend more, depending on when Google thinks it can get you the best results.
At the time of writing (March 26), for most campaigns, Google says you won’t be charged more than 2x your average daily budget on any particular day, and you won’t be charged more than your monthly spending limit, which is 30.4 x your average daily budget in a month. (Google Help)
So if you set a daily budget of £10, you could see up to £20 spent on a busy day, but across the month, you should not be charged more than about £304 for that campaign. (Google Help)
That’s why I always encourage people to think “monthly budget” first, then work backwards to a daily number.
The real question behind “how much per day?”
When someone asks me this, they usually mean one of these:
- What’s the minimum I can spend and still get results?
- How much do I need to spend to get X leads or sales?
- I only have £Y available, what can I realistically achieve with that?
Those are all different questions, and they lead to different answers.
The big fork in the road, are you trying to get new customers, or bring people back?
This is where lots of advice online falls down, it treats all Google Ads spending like it’s the same.
It’s not.
1) Search campaigns, paying for new demand
Search is where you show up when someone actively searches for what you offer right now.
This type of non-branded traffic is usually the most expensive, but it’s often the highest intent too.
If you’re relying on Search to generate leads, you need enough daily budget to buy enough clicks for the campaign to actually learn and perform.
You can run brand search campaigns, which is a different objective altogether and a subject for another blog post, but it is important to mention here that it is possible to do that and for some businesses, it makes sense to do so.
2) Remarketing campaigns, paying for returning demand
Remarketing is where you show ads to people who have already visited your site, or engaged with your brand.
This can be Display remarketing, YouTube remarketing, sometimes Discovery, and it can be much cheaper per click or per view.
So yes, you absolutely can spend a few pounds a day on remarketing, if your goal is simply, “stay visible and bring past visitors back”.
The catch is, remarketing only works if you have enough people in your audience lists, and Google does have minimum audience sizes depending on the network. If your website traffic is tiny, you might not be eligible to run remarketing properly yet.
You also need to ensure you have the correct consent settings in place that adhere to Google’s requirements.
A simple way to work out a sensible daily budget
If you want a practical method that cuts through the noise, use this:
Step 1, estimate your average cost per click (CPC)
You don’t need a perfect number, you just need a rough range.
You can get this from:
- Google’s Keyword Planner
- Your own account, if it’s already running
- Or an educated assumption based on your industry (I’d always rather you assume slightly higher than lower)
Step 2, decide how many clicks you need to make progress
This is the part most people skip.
If you only buy 1 or 2 clicks a day, you might technically be “running Google Ads”, but you’re not giving the campaign enough opportunities to produce enough data to help with consistent results.
As a starting point, ask:
- How many enquiries do I want per week?
- What’s my rough conversion rate from click to enquiry?
Example:
- If your site converts at 5% (1 in 20 clicks becomes an enquiry)
- And you want 5 enquiries per week
- You’ll need about 100 clicks per week
Step 3, turn it into a daily budget
Clicks needed per week × CPC, then divide by 7.
So if you need 100 clicks a week, and clicks cost £3:
- 100 × £3 = £300 per week
- £300 ÷ 7 ≈ £43 per day
That’s how you get to a daily budget that’s tied to reality, not vibes.
The realism check, your daily budget has to match your CPC
This is the bit I wish more people sharing info online would say more clearly.
If your average cost per click is £15, and your daily budget is £50, that’s roughly 3 clicks a day.
Is it impossible to get a lead from 3 clicks a day? No.
Is it likely you’ll get consistent leads, quickly, and enough data to optimise properly? Also no, not for most businesses.
This is why “£10 a day” can be fine for one business, and completely unworkable for another.
It’s not about whether £50/day is a lot of money, it’s about how many chances that budget buys you in the auction.
What pushes daily budgets up or down?
Here are the main levers that change the number, and these are the things I’m looking at when I’m advising a client.
Competitiveness of your industry
Some industries are just expensive because there are lots of advertisers, strong commercial intent, and high customer value.
Your location
Targeting central London is not the same as targeting a small town.
The bigger and more competitive the location, the more likely there will be competition in the auction.
Your keyword intent
Highly specific keywords usually convert better, and sometimes cost less.
Broad, vague keywords can be expensive and messy, and they often soak up budget without turning into leads.
But don’t get this mixed up with broad match types; this is a different concept for a separate blog post.
Your conversion rate
This is a big one that people ignore.
If your landing page converts at 2% instead of 10%, you need five times as many clicks to get the same number of enquiries.
Daily budget doesn’t fix that, improving your website and your offering does.
Your tracking setup and bidding strategy
If you’re using conversion-based bidding, like Maximise Conversions or Target CPA, you need solid conversion tracking, and ideally enough conversion volume for Google to learn what a “good click” looks like.
If tracking is missing or broken, automated bidding can struggle or spend in unhelpful ways.
Budget ranges by scenario, so you can sense check your own plan
I’m going to keep this grounded, because exact numbers vary wildly, but these examples help you pressure test your thinking.
Scenario 1, local service business using Search for leads
- CPCs might be £2 to £8, sometimes higher
- If you want a consistent flow of enquiries, you usually need enough budget for multiple clicks a day, not one click every few days
- A tiny daily budget can work if your niche is very specific and your conversion rate is strong, but most of the time, people underestimate what’s needed to get momentum
Scenario 2, ecommerce, shopping and search combined
- You’re often paying for volume, so daily budgets need to support enough traffic to see what products and search terms convert
- If you spread a small budget across lots of products, nothing gets enough data to perform well
Scenario 3, remarketing only on Display or YouTube
- If your goal is “bring past visitors back”, you often can start small, even a few pounds a day
- The key constraints are audience size, and having enough previous traffic for remarketing to actually run
Scenario 4, high CPC industries
If clicks cost £10 to £30, the whole conversation changes.
At that point, you have to be brutally realistic about:
- profit margin and customer lifetime value
- conversion rate
- whether you can narrow into a very specific niche
- and whether Google Ads is even the right channel right now
Common budget mistakes I see all the time
1) Trying to run Search on a budget that buys almost no clicks
Then, feeling like “Google Ads doesn’t work” (which is understandable).
In reality, the budget never bought enough chances to work.
2) Spending more before tracking is solid
If conversion tracking isn’t set up properly, or it’s tracking the wrong thing, you can spend a lot and still learn nothing.
3) Comparing remarketing budgets to Search budgets
Remarketing and Search do completely different jobs, they need different expectations.
4) Setting automated bidding with unrealistic targets
If you set a Target CPA that your market simply can’t hit, your ads can struggle to show, because you’ve basically told Google, “only run if you can do the impossible”.
5) Switching budgets on and off constantly
I get why people want to do this, especially service businesses that get busy, but constant stop start can make performance choppy, particularly with automated bidding.
(And yes, I’ll write the separate post about switching ads on and off, because it’s a really common question.)
The uncomfortable truth, sometimes Google Ads is just too expensive now
If you asked me ten years ago, I probably would have said most businesses can find a way to make Google Ads work.
More recently, I’ve seen more and more cases where the auction has simply become too expensive for some small businesses.
One example, I worked with a niche mortgage broker where we saw average CPCs go from around £3 per click to over £25 per click in about four years. That’s a huge jump.
When costs climb like that, it isn’t just “a bit more expensive”, it changes the economics completely.
It also often means the threshold to even enter the auction is high, so smaller budgets barely get a look in.
At that point the best move might be:
- narrowing your targeting to a tighter niche, to bring CPCs down
- using remarketing and brand protection rather than broad lead gen
- investing in organic content and partnerships
- building referral engines and email lists
- or exploring alternative channels where the costs are more manageable
There is no shame in deciding Google Ads is not the right tool right now, it’s better to be realistic than to bleed money hoping it magically improves.
How to scale your budget safely once it’s working
If you’ve got a campaign that is generating profitable leads or sales, scaling is usually simple, but it needs to be controlled.
- Increase budgets gradually, not in big random jumps
- Watch lead quality, not just lead volume
- Keep an eye on search terms, CPC, and conversion rate
- Make sure tracking stays clean, or your decisions will get messy fast
If all else fails, get a second pair of eyes on it
If you’ve read this and you’re thinking, “I still don’t know what’s realistic for my business”, that’s exactly what my Google Ads Power Hour is for.
We jump into your account together, we’ll look at your CPC reality, your conversion tracking, your targeting, and we’ll work out what budget makes sense for what you’re trying to achieve.
And genuinely, zero judgement.
I’ve been doing this for 20 plus years, I’ve seen it all, and I’ve probably made most of the common mistakes myself at some point over the years too.
Sometimes it’s a ten-minute fix; sometimes it’s a bigger rethink. Either way, you’ll leave knowing exactly where you stand and what to do next.
FAQ, daily budgets and common “is this enough?” questions
Is £10 a day enough for Google Ads?
Sometimes, but only in the right context.
£10 a day is effectively a testing budget, not a “consistent lead machine” budget. Whether it’s enough comes down to what that £10 buys you in clicks.
- If your average CPC is £1, £10/day could buy around 10 clicks a day, that’s enough volume to start learning.
- If your average CPC is £5, £10/day is more like 2 clicks a day, progress will be slow, and results will be patchy.
- If your average CPC is £15, you might not even get a click every day, and it’s highly unlikely you’ll generate consistent leads.
So yes, £10/day can work, but only if the CPCs in your space are low enough, and your expectations match the reality of the data you’ll collect.
Is £5 a day worth it?
It can be, but usually not for Search lead generation.
£5/day is much more realistic for remarketing, especially Display or YouTube remarketing, where the goal is to bring past visitors back, and you’re paying less per click, or per view.
For Search, £5/day often doesn’t buy enough clicks to learn properly, unless you’re in a very low competition niche with low CPCs.
The “worth it” question is really, “does this budget buy enough chances to achieve my goal?”
How much should a small business spend on Google Ads per day?
There isn’t one number that fits every small business, because small businesses sit in totally different auctions.
A better way to think about it is:
- What’s my rough CPC?
- How many clicks do I need each week to get enquiries or sales?
- What daily budget buys me that click volume?
If you’re not sure where to start, use the Google Ads rule of reality, your budget needs to buy enough clicks to give you a fighting chance, and that’s usually more than one click every few days.
How much should I spend on Google Ads per month, not per day?
This is often the better way to think about it.
Google Ads uses an average daily budget, and Google can spend up to 2x your daily budget on a given day, as long as it stays within your monthly spending limit, which is usually 30.4x your average daily budget across the month. (Google Help)
So if you’re thinking monthly first, you can set a monthly “comfort level” and work backwards into a daily number.
Can Google Ads spend more than my daily budget?
Yes, on some days.
For most campaigns, Google can spend up to two times your average daily budget on a particular day, then it balances out across the rest of the month so you don’t exceed the monthly limit (again, usually 30.4 times your daily budget). (Google Help)
This is one reason I always say, don’t panic if you see a higher spend on one day, check the bigger picture.
What’s a good daily budget for remarketing?
Remarketing budgets can often be small, a few pounds a day, because you’re targeting a warmer audience and you’re not paying the same prices as high intent Search clicks.
The main constraint is audience size. To run remarketing, your lists usually need at least 100 active users in the last 30 days across Display, Search, and YouTube. (Google Help)
So remarketing is a great option if you have the traffic, and you want to keep nudging people back to enquire or buy.
Why does Google Ads keep telling me to increase my budget?
Because Google’s job is to get more opportunities into the auction, and higher budgets can unlock more impressions and clicks.
But “increase budget” doesn’t automatically mean “you’ll get profit”.
If your CPCs are high, and your conversion rate or margins don’t support those costs, spending more can just lose money faster. The better question is, “if I increase budget, will I get more of the right clicks, at a cost that still makes sense?”
What if my CPC is really high, like £10 to £25 a click?
Then you have to be brutally realistic about what your daily budget can achieve.
If clicks are £15 and you’re spending £50/day, that’s roughly 3 clicks a day, it’s not impossible to get leads, but it’s a tough setup unless you have:
- a strong conversion rate
- a strong offer
- solid tracking
- and enough profit margin or lifetime value to absorb higher costs
In some markets, the auction genuinely becomes too expensive for smaller businesses, and the smarter move is narrowing your targeting hard, leaning on remarketing, or investing in other channels alongside Google Ads.
When should I stop or pause Google Ads because the costs are too high?
If you’re consistently seeing that:
- CPCs are high, and
- cost per lead or sale is above what you can afford (unprofitable), and
- you’ve already tightened targeting, improved ads, and improved landing pages
then pausing might be the right call.
There’s no shame in it. Google Ads isn’t “good” or “bad”, it’s a tool, and sometimes the economics don’t stack up for a particular business model in a particular market.
