Solved: Best practices for scaling Facebook Ads during the day?

Hi there,

Thanks for reaching out!

That's a really good question, and one that comes up alot with advertisers who are starting to see some success and want to capitalise on it. It’s tempting to pour more money into something thats working well, but how you do it makes all the difference between stable growth and wrecking a good campaign. I'm happy to give you some of my initial thoughts and guidance based on what I've seen work across many accounts.

Scaling a campaign isn't just one single action, it's a process. And your question about scaling during the day versus the next day gets right to the heart of a common dilemma: speed vs. stability. Let's break it down.

I'd say you should focus on smart, stable scaling...

Okay, so your campaign is hitting a great ROAS and you want to scale up. The impulse to increase the budget immediately, multiple times a day, is understandable. You see good returns and you want more of them, right now. This is what we'd call intra-day scaling.

Intra-day Scaling (e.g., 10-20% every few hours):

To be brutally honest, this is a very risky strategy. While it can feel proactive, you're playing with fire. Every time you make a significant edit to an ad set's budget, you risk resetting the learning phase. Meta's algorithm thrives on data and stability. When you keep changing the budget, you're not giving it a stable environment to learn who your best customers are and how to reach them efficiently. Bumping the budget by 10-20% every hour or two is almost guaranteed to disrupt the algorithm's performance.

You might see a short-term boost, but more often than not, you'll see performance become erratic. Your ROAS might suddenly tank, your CPA shoots up, and the campaign that was a winner yesterday is now a loser. The reason why is because the algorithm, it needs time to adjust to a new budget and spend it effectively across the 24-hour cycle. Constant changes mean it's always playing catch-up and never gets to optimise properly. I wouldent recommend this approach for consistent results.

Next-day Scaling (e.g., 10-20% for the following day):

This is the much safer, more consistent, and professional approach. By making a single budget increase of 10-20% for the next day (usually done the evening before), you give the algorithm a clear, stable parameter to work with for the full 24-hour period. It can plan its spend, pace the delivery, and continue to optimise based on the data it has gathered.

This method leads to far more predictable and stable growth. It's less exciting, for sure, but paid advertising is about profitable consistency, not chasing thrilling spikes that can't be sustained. If a campaign is genuinely performing well over a few days (not just a few hours), a steady daily increase is the way to build its budget and delivery without shocking the system. This is the method we've used to scale campaigns for clients to great heights. For instance, I remember one campaign we ran for a subscription box where we achieved a 1000% Return On Ad Spend. That wasn't done with frantic, hourly budget changes; it was built on a foundation of stable, methodical scaling of winning campaigns.

So, to answer your question directly: for consistency, scaling the budget 10-20% for the next day is miles better. Intra-day scaling is a tactic best avoided unless you have a very specific, short-term reason and are willing to accept the high risk of destabilising your campaign.

We'll need to look at your campaign foundations before you even think about scaling...

Before you even decide *how* to increase the budget, you need to be certain the campaign is truly ready to be scaled. A few good hours of high ROAS doesn't mean a campaign is a long-term winner. It might have just hit a lucky pocket of users.

First off, your campaign objective is everything. I assume your optimising for conversions (like purchases or leads), as this is the only way to properly measure ROAS. If you're optimising for anything else, like traffic or engagement, then ROAS is a vanity metric and scaling is premature. You gotta be optimising for the final goal.

Second, how long has the campaign been performing well? A solid winner maintains a good ROAS for at least 3-5 days, and ideally is out of the learning phase. Scaling a campaign that's still in learning, or one that has only had one good day, is just gambling. You need to see a stable trend.

The structure of your campaign is also hugely important for scaling. You should be split testing creatives and audiences within separate campaigns. This way, you can clearly identify which specific combinations are working and scale those, rather than just blindly increasing the budget on a campaign with a mix of good and bad ad sets inside it. Scaling should be precise. I remember one campaign we did for a medical job matching SaaS where we reduced their Cost Per User Acquisition from £100 to £7. This involved overhauling their campaign structure to isolate and scale only the most efficient ad sets.

So, before you scale, ask yourself:
-> Is the campaign optimised for my primary conversion goal?
-> Has it been performing consistently well for several days?
-> Is it out of the learning phase?
-> Do I know exactly which audience and creative is driving this performance?

If the answer to any of these is 'no', you should focus on fixing that foundation rather than increasing the budget.

You probably should get your targeting spot on for sustainable growth...

The single biggest factor in whether a campaign can be scaled successfully is the audience. You can have the best creative in the world, but if you're showing it to the wrong people, it's useless. And as you increase the budget, Meta will try to find more people like your initial audience. If that initial audience wasn't spot-on, your performance will get worse as you scale, not better.

When I audit client accounts, I often see a scattergun approach to audience testing. The key is to be methodical and prioritise audiences based on how likely they are to convert. Think of it as a funnel. The audiences at the bottom of the funnel (BoFu) are the warmest and should perform best. The ones at the top (ToFu) are cold and will be harder to convert.

Here’s how I’d prioritise audiences for an eCommerce account, but the logic applies to almost any buisness:

BoFu (Bottom of Funnel - Hottest Audiences):
These are people who have shown strong intent. They are your lowest-hanging fruit and your first priority for retargeting.
-> Added payment info
-> Initiated checkout
-> Viewed cart
-> Added to cart

BoFu - Previous Customers:
Your existing customers are an absolute goldmine for repeat business or promoting new products.
-> Highest value previous customers
-> All previous customers (e.g., purchased in last 180 days)

MoFu (Middle of Funnel - Warm Audiences):
These people are aware of you but haven't shown buying intent yet. The goal here is to pull them deeper into the funnel.
-> Visited a landing or product page (but didn't add to cart)
-> Visited your website
-> Watched a significant portion of your videos (e.g., 50% video viewers)

ToFu (Top of Funnel - Cold Audiences):
These are people who haven't heard of you before. This is where you find new customers, but it requires more testing.
-> Lookalike audiences: This is critical. You want to create lookalikes based on your BEST customers first. A lookalike of 'Purchasers' is far more valuable than a lookalike of 'All Website Visitors'. You should test them in order of value: lookalikes of highest value customers, then purchasers, then initiated checkouts, and so on. You need at least 100 people in your source audience, but honestly, you want a thousand or more for a quality lookalike.
-> Detailed targeting (interests, behaviours): This is where you start with a brand new account. The trick is to be specific. If you sell high-end camera gear, targeting the interest "Photography" is too broad. You'll get millions of people who just like taking photos on their phone. You'd be better off targeting interests like specific professional camera brands, famous professional photographers, or software like Adobe Lightroom. Think about what your ideal customer is *uniquely* interested in.

When you find a winning ad set with a specific audience, *that* is what you scale. And as you scale, you monitor its performance closely. If the ROAS starts to drop, it might be a sign of audience fatigue, and it's time to introduce new creatives or test a new audience.

You'll need more than just budget increases to scale properly...

This is a mistake many advertisers make. They think "scaling" just means "more budget". True scaling is about improving the overall efficiency of your entire marketing funnel, which allows you to spend more money profitably.

1. Creative Optimisation: Your ads will eventually fatigue. The same audience will get tired of seeing the same ad, and your CTR will drop and CPA will rise. You need a constant process of testing new creatives.
-> Test different formats: image vs. video vs. carousel. We've had B2B SaaS clients see fantastic results from simple User-Generated Content (UGC) style videos. It feels more authentic and can outperform slick, corporate videos.
-> Test different angles: If you're selling a product, test ads that focus on a specific feature, a customer testimonial, the problem it solves, or a special offer. You need to keep things fresh to keep your audience engaged as you scale.

2. Funnel and Landing Page Improvement: You could have the best ad campaign in the world, but if it sends traffic to a slow, confusing, or untrustworthy website, your going to waste all that money. Even a small improvement in your website's conversion rate can have a massive impact. If you can increase your conversion rate from 2% to 3%, you've just made your ad spend 50% more effective without even touching your campaigns. This means you can now afford a higher cost per click and scale your budget further while maintaining your target ROAS.

3. Increasing Customer Lifetime Value (LTV): This is a more advanced thought. If you can get more value from each customer you acquire, you can afford to spend more to acquire them in the first place. This could mean improving your email marketing to encourage repeat purchases, introducing a subscription model, or upselling higher-ticket items. I remember working with a client selling online courses, where we generated $115k in revenue in just 1.5 months using Meta Ads. A huge part of that was having a clear value ladder, so once a customer was in, there were opportunities to sell them more, which increased the overall LTV and justified a higher initial ad spend.

So when you think about scaling, don't just look at the budget button in Ads Manager. Look at your whole system. A stronger creative library, a higher-converting landing page, and a better LTV are all powerful levers for scaling.

You'll need a realistic view on costs as you scale...

It's important to understand that it's almost impossible to scale a campaign indefinitely while maintaining the exact same ROAS. As you spend more, Meta has to reach further out to find new people. It will start with the people most likely to convert, but as you push the budget, it has to go for people who are less and less likely. This is normal. It's called the law of diminishing returns.

Your spend will plateau at some point where you can't scale further without a lower ROAS or higher CPA. The goal is to find the sweet spot where you are getting the maximum number of conversions at a ROAS that is still profitable for your business.

To give you a rough idea of costs, though this varies massively by industry, country, and offer, here are some general ballpark figures we see. Keep in mind your performance is unique to you.

As you can see, there's a huge range. If your ROAS is incredible right now, expect it to normalise towards a lower (but hopefully still very profitable) number as you increase your spend. Understanding these numbers helps you set realistic targets for your scaled campaigns.

This is the main advice I have for you:

To pull all this together, here’s a table outlining my main recommendations for you to implement a more robust and sustainable scaling strategy. This is a framework for thinking, not just a set of instructions.

As you can probably tell by now, effectively scaling a paid advertising campaign is a complex process with a lot of moving parts. It's not just about pushing a button; it's about a deep understanding of audience behaviour, creative strategy, funnel mechanics, and the nuances of the advertising platform's algorithm.

It's about balancing all these elements correctly to drive sustainable, profitable growth. That's where having an expert can make a huge difference. A professional consultancy like ours spends every day in these platforms, managing millions in ad spend, and learning what works across dozens of industries. We can help you navigate these complexities, implement a robust strategy, and take over the day-to-day management and optimisation to ensure your budget is working as hard as it possibly can to grow your business.
