What Is Retargeting and How Does It Work for SA Businesses?

The average South African business website converts less than 3% of visitors into leads or customers on their first visit. That means 97% of people who found your website, showed genuine interest, and then left — without taking action. Retargeting is how you get a second chance with those visitors. This guide explains exactly how retargeting works, which platforms offer it in South Africa, and how to get started.

What Is Retargeting?

Retargeting (also called remarketing) is a form of digital advertising that specifically targets people who have previously visited your website, watched your video, or interacted with your social media content. Instead of reaching cold audiences who have never heard of you, retargeting shows your ads specifically to warm audiences already familiar with your brand — dramatically increasing the likelihood of conversion.

How Retargeting Works: The Technical Process

1. A visitor lands on your website through any channel (organic search, Google Ads, social media, or direct)
2. A tracking pixel (Meta Pixel, Google Tag, or similar) adds the visitor to a retargeting audience
3. The visitor leaves your website without converting
4. Your retargeting ad appears to that specific visitor as they browse other websites, use social media, or search Google
5. The visitor clicks your retargeting ad and returns to your website — now more likely to convert

Why Retargeting Is So Cost-Effective for SA Businesses

Retargeting audiences have already demonstrated intent — they visited your website, viewed a product, or started a form. This prior engagement means retargeting ads consistently deliver 3-5x higher conversion rates than equivalent campaigns targeting cold audiences. For most South African businesses, this makes retargeting one of the highest-ROI digital advertising investments available.

Retargeting Costs in South Africa

Retargeting ads typically cost significantly less than cold-audience campaigns because audience sizes are smaller. On Google Display, expect CPCs of R1-R8. On Facebook and Instagram, CPMs (cost per 1,000 impressions) of R30-R120 are typical for SA retargeting audiences. Despite the lower cost, retargeting often generates the highest ROI of any paid channel because of the higher conversion rates from warm audiences.

Frequently Asked Questions

Do I need a minimum amount of website traffic for retargeting to work?

Yes. Retargeting audiences need to reach a minimum size before ads can serve — typically 100 unique visitors on Google and 1,000 on Facebook for a standard campaign. For most South African businesses receiving fewer than 500 monthly visitors, retargeting audiences may be too small to generate consistent ad delivery. In this case, we recommend prioritising driving more traffic first through SEO or primary paid campaigns before focusing on retargeting.

Is retargeting the same as remarketing?

The terms are often used interchangeably, though there’s a subtle difference. Remarketing originally referred to Google’s specific product for targeting past website visitors, while retargeting is the broader industry term for the same concept across all platforms. In practice, most South African marketers use both terms to mean the same thing: advertising specifically to people who have previously interacted with your business online.

Can customers tell they’re being retargeted?

Technically yes — ads appear to follow them after visiting a website, and most users recognise this pattern. However, this visibility is generally positive when done correctly. Seeing your brand’s professional, relevant ads after visiting your website reinforces trust and brand recall. What feels intrusive is frequency overexposure — the same ad appearing 20 times a day. We set frequency caps on all retargeting campaigns to ensure brand-building rather than audience irritation.

How long should I retarget visitors after they’ve left my website?

Retargeting window depends on your sales cycle. For immediate-intent services (emergency plumber, dentist booking), a 7-14 day window is typically sufficient. For considered purchases like real estate or professional services where the decision takes longer, a 30-90 day retargeting window is more appropriate. Longer windows with reducing ad frequency over time prevent audience fatigue.

Should I use retargeting alongside my main Google Ads or Facebook campaigns?

Yes, absolutely. Retargeting should always run alongside your primary campaigns. Your primary campaigns drive traffic and awareness; your retargeting campaigns re-engage the portion of that traffic that didn’t convert immediately. Running retargeting alone without primary traffic campaigns creates audiences too quickly exhausted to sustain consistent ad delivery.
