What ads for previous visitors are (remarketing)

Remarketing campaigns appear only to people who visited your website, viewed a product, added to cart, or interacted with your profile. Instead of introducing the business to strangers, they remind people already interested. They work through the Meta pixel or Google tag installed on the website.
They usually have the lowest cost per sale because previous viewers need less persuasion. On Black Friday, they bring back people who abandoned October carts waiting for discounts.
How does remarketing work?
A pixel is website code recording visitor actions: viewing products, starting checkout, buying. Meta and Google retain this list without revealing identities and let you advertise only to those people. Choose an audience such as “visited within 30 days without buying.”
Many discover this detail late: list building starts only after installation. Install on November 20 and there is no Black Friday list. Install in October and you have a month of visitors. The glossary explains pixels; the setup and measurement guide gives instructions.
When is it worthwhile?
When the site already has visitors. At 300 monthly visitors the list is small but your warmest audience; R$ 10 daily often covers it. Google requires at least 100 active users in the last 30 days to start showing ads. At 3,000 visitors, remarketing can be the month’s main campaign.
It is unsuitable with no visitors: nobody to remind. Nor should the same person see the same ad 20 times; limit frequency.
A specialty coffee store installs a pixel in October and in November advertises only to product viewers who did not buy: “The kit you viewed has free shipping through November 27.” Cost per sale is a fraction of cold-audience ads.
What to do now
Check that the pixel is installed and records purchases, not just visits. If absent, install this week: November’s list is built now. We build measured ads from click to CRM: avilaops.com/meta-ads-para-empresas or WhatsApp: wa.me/5517997811471.
Frequently asked questions
Are remarketing and retargeting the same?
In practice, yes. Both describe advertising to people previously in contact with your business.
Does remarketing work with Instagram only, without a site?
In a limited way: you can advertise to profile interactors. Without a website pixel, you lack the most valuable audience, “viewed a product but did not buy.”
Does remarketing comply with the LGPD?
It can if the privacy policy explains cookies and the pixel, and the ad pixel loads only after visitors accept through the cookie notice. Offering later refusal is insufficient: data has already been sent. The platform holds the list without identifying people to you, but the store remains responsible for data the pixel sends.
