How much to spend on Facebook and Instagram ads is a question I get asked a lot and the answer depends on your industry, your audience and your profit margins.
I have put together this blog to help you understand what your Facebook and Instagram ad spend could be.
What are your objectives?
Before you start any advertising on any platform, you need to know why you are doing it. What is the purpose of this ads, what do you want to achieve from it?
What are your existing costs?
Here are some important numbers you need to know:
Current cost per lead and sale!
What is the current cost to get an enquiry? I recommend splitting this out by enquiry type (e.g newsletter sign up, contact form etc). and channel (e.g. Google Search, Facebook Ads..)
This will help you understand what your current costs are so that when you start advertising, you have something to aim for.
Website conversion rate
What is your current website conversion rate from different channels? This will help you understand how many website visitors you need in order for a user to convert (e.g sign up to a newsletter, make a purchase, contact you etc)
Who is your audience?
No, it’s not everyone! #sorry
Come up with personas of your target audience – who are they? What do they do? What are their interests?
This is going to help you build audiences and discover the size of potential prospects in the Facebook audiences tool. Your budget is going to impact how big your Facebook audiences are – for example, if your budget is £15 a day, you’re not going to effectively be able to go after millions of people.
There is a metric called ‘frequency’ on social ads, which is the average number of times someone has seen your ad. This directly correlates to your budget and audience size.
You’re going to want someone to see your ad at least a couple of times for them to take an action. In order for that to happen, you need enough budget for the size of the audience.
When building your audience, Facebook will give you estimates of reach and you can start doing some modelling on how much budget you think you will need to get a desired frequency.
What is your existing marketing budget?
When it comes to Facebook advertising, you could spend £10 a day right up to millions of pounds, so you need a rough idea of what your budget will be.
Everything we’ve done so far should have helped you narrow down your options for the best results, and now it’s time to think about targets.
Although it’s difficult to know exactly what your CPAs (cost per acquisition) will be if you have not advertised on the platform before, by having some figures from Step 2, you can come up with some rough costs to start with.
Here’s an example:
Leads target is 50 web form submissions
Current website conversion rate is 1.50% from paid activity
Current average cost per click is £0.50 (if you don’t know this, research some industry averages)
In order to get 50 leads you therefore need 3,200 visitors (Visitors/conversion rate = sales)
Ad spend = £1,600 (£0.50 x 3,200)
CPA = £32 (£1,600/50)
These figures are a very rough guide, but it will help you if you’re struggling to know what to start with. Facebook advertising fluctuates depending on the time of year and your costs will differ depending on quality of creative and overall product.
Don’t expect results straight away
You shouldn’t expect results straight away, it will take time to test different creatives, audiences and objectives to get your desired result. You shouldn’t edit a campaign in the first 7 days of it launching, this is when Facebook ‘learns’ so don’t panic after the first 24 hours. Give it time.
You also need to consider your frequency levels – if your campaign is struggling to get a frequency higher of 1 and you wanted at least 2, consider giving it more budget or reduce the audience size.
It’s also important to note that your remarketing audiences (e.g. people that have been to your website, people that know you or have purchased from you before) will have a lower CPA than prospecting audiences.
Our advice is always to split these audiences out. Have separate campaigns for remarketing and prospecting. This will allow you to monitor the cost per sale for each type of audience.
It is also not that straightforward
Attribution – every advertiser’s nightmare! It’s rare that a user will see a Facebook Ad, click on it and buy off you straight away. There are many different touchpoints now, as we highlighted in our attribution article.
Additionally, with the recent iOS privacy changes, Facebook attribution could become even harder to analyse. Remember to not look at social advertising on its own, it’s part of a bigger picture, working together with your other channels.
Following the steps above will help you determine the right META advertising budget for your business. It’s important to understand your numbers and goals, industry data, and your own personal business conversion data. Then determine how you want to distribute that budget among ads for building your audience, promoting your offer, and retargeting.
