Facebook and Instagram retargeting
Retargeting shows Facebook and Instagram ads to South Africans who already visited your website or engaged with your brand, making it the cheapest and highest-converting Meta campaign you can run. Well-built retargeting often returns 5x to 10x on ad spend.
Most people who visit your website leave without buying or enquiring. Retargeting brings them back. For South African businesses, it is consistently the most profitable slice of a Meta advertising budget, yet it is the piece most small advertisers skip. Here is how to build it properly.
TL;DR: Quick Answer
Retargeting (or remarketing) re-shows Facebook and Instagram ads to people who already interacted with your business: website visitors, video viewers, page engagers and past customers. Because these audiences are warm, retargeting in South Africa typically converts far cheaper than cold prospecting, often at 5x to 10x return on ad spend. Set it up with the Meta Pixel and custom audiences, segment by how recently and how strongly people engaged, cap frequency so you do not annoy them, and refresh creative every few weeks.
Key takeaways
- Retargeting reaches people who already know you, so it converts far cheaper than cold ads
- You need the Meta Pixel installed before you can build website custom audiences
- Segment audiences by intent: cart abandoners convert better than blog readers
- Cap frequency to avoid ad fatigue and brand annoyance
- Refresh retargeting creative every two to four weeks to keep performance up
- Retargeting works best alongside, not instead of, cold prospecting campaigns
If you are running Meta ads without retargeting, you are paying to bring people to your website and then letting most of them walk away forever. Retargeting closes that gap. For South African businesses it is the single most efficient campaign type available, and it is well within reach of a modest budget.
What is Facebook and Instagram retargeting?
Retargeting is showing Facebook and Instagram ads specifically to people who have already engaged with your business. That includes visitors to your website, people who watched your videos, anyone who interacted with your Facebook or Instagram profile, and your existing customer list. Instead of paying to introduce yourself to strangers, you pay to follow up with people who already know you.
It works through custom audiences in Meta Ads Manager, built from the Meta Pixel on your website and from engagement data Meta already holds. Once an audience is defined, you serve it tailored ads that nudge people back towards the action they did not complete the first time.
Why does retargeting convert so well?
Retargeting converts at a far lower cost than cold advertising because it speaks to warm, familiar audiences who already trust your brand. A first-time visitor may need several touchpoints before buying. Retargeting provides those touchpoints efficiently, reminding people of what they looked at and giving them a reason to come back.
In practice this means a South African retargeting campaign often returns 5x to 10x on ad spend, compared with 2x to 4x for cold prospecting. The catch is scale: your warm audience is only as big as your traffic, so retargeting amplifies a funnel rather than replacing the top of it.
Facebook and Instagram retargeting in South Africa typically returns 5x to 10x on ad spend, well above the 2x to 4x of cold prospecting. It works by re-engaging warm custom audiences (website visitors, video viewers, page engagers and past customers) built from the Meta Pixel. Retargeting amplifies an existing funnel and is most effective when paired with cold campaigns that feed it new traffic. Source: Juicy Designs campaign data, South Africa, 2024-2026.
How do I build custom audiences for retargeting?
Custom audiences are the building blocks of retargeting, and the most valuable ones come from your Meta Pixel. Start by installing the Pixel and Conversions API, then create audiences such as:
- All website visitors in the last 30, 60 or 90 days
- Product or service page viewers who showed specific interest
- Add-to-cart or checkout abandoners for e-commerce
- Video viewers who watched 50% or more of a video
- Instagram and Facebook engagers from the last 365 days
- Customer lists uploaded from your CRM for win-back campaigns
What does a simple retargeting funnel look like?
A good South African retargeting funnel segments audiences by intent and shows each one a relevant message. Someone who abandoned a cart needs a different nudge from someone who read a blog post. A simple, effective structure:
- High intent: cart abandoners and checkout starters get an offer, a reminder or free-shipping prompt within 1 to 3 days.
- Mid intent: product and service page viewers get social proof, testimonials and case studies.
- Low intent: general visitors and engagers get brand-building content and your strongest single offer.
“The biggest retargeting mistake we fix is treating every visitor the same. A cart abandoner and a blog reader are worlds apart in intent. Match the message to the behaviour and your cost per sale drops immediately.”

How do I manage frequency and creative?
Retargeting audiences are small, so the same people see your ads repeatedly, which makes frequency control and fresh creative essential. Set a frequency cap, aim for roughly three to seven weekly impressions per person, and rotate two or three creatives per audience. When frequency climbs but conversions stall, that is your signal to refresh the creative before fatigue erodes results. Our guide to testing Facebook ad creative covers how to do this systematically.
How much should I spend on retargeting?
Allocate roughly 15% to 30% of your total Meta budget to retargeting, with the rest on cold prospecting that feeds the funnel. Because the audience is small, pouring too much into retargeting just inflates frequency. For many South African SMEs, R1,500 to R3,000 a month on retargeting is enough to recover meaningful revenue.

Frequently asked questions
What is the difference between retargeting and remarketing?
The two terms are used interchangeably in South Africa. Both mean showing ads to people who have already engaged with your business. Technically, remarketing sometimes refers to email follow-ups while retargeting refers to paid ads, but on Meta they describe the same thing: re-engaging a warm custom audience with Facebook and Instagram ads.
What return on ad spend does retargeting deliver in South Africa?
Retargeting typically returns 5x to 10x on ad spend in South Africa, well above cold prospecting, because you are advertising to people who already know and trust you. The trade-off is reach: retargeting audiences are small, so they cannot carry your whole budget. Use retargeting to convert the warm traffic that cold campaigns generate.
Can I retarget without the Meta Pixel?
You can retarget engagement audiences (people who interacted with your Facebook or Instagram profile, watched your videos, or are on a customer list) without the Pixel. But to retarget website visitors, which is usually the most valuable audience, you need the Meta Pixel installed and collecting data first. Install it as early as possible so the audience is ready when you launch.
How often should retargeting ads appear?
Aim for a frequency of roughly three to seven impressions per person per week. Below that, you may not stay top of mind; far above it, you risk irritating people and wasting budget. Set a frequency cap, watch your frequency metric in Ads Manager, and refresh creative when it climbs without conversions improving.
Is retargeting worth it for a small South African business?
Yes, especially for small businesses with limited budgets, because retargeting wrings the most value out of the traffic you already have. Even a small retargeting budget of R1,500 to R3,000 a month can recover enquiries and sales that would otherwise be lost. It is one of the highest-ROI uses of a modest Meta budget.
