One of the most common Facebook Ads issues I see is improper campaign scaling. Tell me if this sounds like you. You launch a small campaign and optimize it for a few weeks, eventually getting a really good CPA. Time to scale up, so you increase your daily ad budget from say $50 to $250. Two or three days later, you suddenly realize it’s all gone to hell.
First, let me explain why it’s all gone to hell. Facebook optimizes your campaign serving ads to those people in your target audience that are most likely to convert. When you increase your budget without making other changes, Facebook is forced to serve ads to a larger (less optimal) portion of your audience… and down go conversions. To make matters worse, increasing your budget also accelerates ad fatigue (serving your ad more frequently to the same people), shortening the (profitable) life of your campaign.
Now that we know what not to do, I’m going to provide you with a 3-step approach to scale Facebook campaigns like a pro.
Step 1 – Increasing Budgets
The first rule of increasing budgets is GO SLOW and the second rule is WAIT! I recommend increasing FB budgets by a maximum of 20% at a time. A modest increase in your budget is much less likely to have a dramatic effect on CTRs, CPCs, or CPAs. Next, wait for a minimum of 72-hours – if you have a small budget of less than $25/day or generate less than 2-3 conversions/day give it a full 7-days. Facebook’s algorithm needs this time period to adapt to your new budget.
After the waiting period has elapsed have a look at your performance reports. Are you seeing any of the following?
a) Higher CPA
b) Lower CTR
c) High ad frequency (above 5 is worrisome)
If your numbers still look good you can go ahead and make another incremental increase. Rinse and repeat as long as your CPA, CTR, and Ad Frequency numbers are within tolerance. Seeing a drop-off in performance? Let’s head to step 2.
Step 2 – Adjusting Your Audience
As a rule of thumb, I like to have a minimum audience size of 100,000 for every $50 of daily ad spend. A bigger audience is ALWAYS better if you are hitting your target CPA because (a) you have room to expand your budget without affecting your CPA, and (b) your campaign can run much longer before ad fatigue sets in.
If you’re seeing performance drop off after increasing your budget, your audience is likely too small and needs to be expanded. There are a number of options for expanding your audience, and there is no right or wrong. But ideally, we’re looking to increase your audience to match or exceed the 100K/50 rule above.
Let’s have a look:
a) Turn on Expanded Audiences
Clearly, the easiest way to significantly increase your audience, turning on this feature allows FB to target more broadly based on the best performing members of your target audience. This option can work especially well for mass market consumer products. The feature tends to work much less well with niche or B2B products where audience specificity is important.
b) Create Look-A-Like Audiences
Look-A-Like audiences match a percentage of target country FB users that are similar to an existing custom audience. Your best choice for a look-a-like is usually people that have already converted. That said, ensure that you have a minimum of several hundred and preferably a few thousand “converted” users in your list to ensure high-quality matching is possible. Start with a 1% match, which in the US will give you around 3 million new people to target.
c) Modify Your Target Audience
If you’ve found certain interests perform well, look for similar interests or behaviours to expand the audience size. You may also consider relaxing some of your “AND” requirements if you’ve optimized elsewhere like in placements or creatives.
d) Remarketing Audiences
While you can add remarketing audiences such as website visitors, people already on your email newsletter distribution list, etc., I prefer running separate campaigns to these folks. But if you’re stuck, feel free to add them; just remember to split them out into their own ad set so you can monitor performance separate from your other target groups.
Once you’ve updated your audiences let your campaign run for another 72-hours or 7-days as above and see how performance is affected. If things are looking good go back to step 1.
If after increasing your audiences substantially, you’re still seeing lacklustre performance it’s time to move onto step 3.
Step 3 – Optimizing/Refreshing Creative
No matter how great your creative is there are two problems with it. First, there is no such thing as perfect, you can ALWAYS make better ads. Second, even very high performing creative has a shelf life and will suffer from ad fatigue eventually. But don’t confuse ad performance with fatigue, here’s how you can tell them apart.
When you experience ad fatigue you will typically see a fairly high ad frequency along with a degradation of performance (particularly CTR) over time.
Here are two different split testing methodologies you can try:
a) Test new ad elements (works best when there is no ad fatigue)
Make several variations of your ad changing just 1 element such as the headline, image, or link text. Test these new variations against the original and then kill off low-performing variations as soon as you see statistically significant results. When you’ve completed one full test circle back and test a new element. You can keep repeating this as long as you don’t see signs of ad fatigue.
b) Test fresh creatives (works best when you have ad fatigue)
Create completely different ad units with new headlines, top text, image, and link text. Run several of these fresh creatives against your baseline best performing ad.
Seeing a good boost in performance after updating your creatives? Great, make another incremental increase to your budget.
