Social ads: what they are, platforms and how to advertise on social media
The platforms, formats and steps to make your social media ads deliver results
Social ads are paid ads on social networks such as Facebook, Instagram, TikTok or LinkedIn. They let you show a message to people who don’t follow the brand yet, chosen by their age, interests or behavior.
They are also known as social media advertising. Other common terms are paid social and social media ads.
Social refers to social networks, and ads is short for advertisements. Social ads are the paid part of a social media strategy. The other part is organic posts, which you don’t pay for.
| Organic posts | Social ads | |
|---|---|---|
| Cost | Free (only the time it takes to create them) | You pay for impressions, clicks or results |
| Reach | Mostly your followers | Any user who matches your audience |
| Targeting | Limited | By age, location, interests and behavior |
| Results | Slow and cumulative | Fast, for as long as you keep investing |
Each network has its own ads manager. The process is similar on all of them:
1. You choose an objective. Awareness, website traffic, engagement, leads or sales.
2. You define the audience. By demographics, interests or behavior. You can also use custom audiences, such as people who visited your website, and lookalike audiences based on your customers.
3. You set the budget. Daily or lifetime, and how much you’re willing to pay.
4. You create the ad. Text, image or video and a call-to-action button.
The network then delivers the ads through an auction. Depending on the objective, you pay per thousand impressions (CPM), per click (CPC) or per result.
Social ads platforms
These are the most widely used ones and what each is best for:
| Platform | Where the ads appear | Best for |

Stories and reels. Full-screen vertical ads between stories or short videos.
Lead forms. Users leave their details without leaving the social network.

Keep every click from your ads
Send the traffic from your ads to a Mailrelay form and turn visitors into subscribers.
1. Define the objective and the metric. For example, getting sign-ups at a specific cost.
2. Choose the network. The one your buyer persona uses, not the one that’s trendy.
3. Prepare the offer. A discount, a free trial or a lead magnet, such as a downloadable guide.
4. Create several versions of the ad. Try different copy and images, as in an A/B test.
5. Send the click to a page built for it. A landing page with a simple form.
6. Measure and adjust. Check the CTR, the cost per result and the ROAS, and move the money to what works.

Social ads and email marketing
Social ads bring in traffic while you pay. Email lets you keep those people once the campaign ends.
That’s why many of your ads should aim for subscribers, not just sales. Anyone who leaves their email in a subscription form or a lead form becomes a contact you own. You can then send them a welcome email and your newsletters without paying again for every impression.
It also works the other way around: you can upload your list to the social network to exclude existing customers or to create lookalike audiences. Only do this if your contacts gave their consent for that use, as the GDPR requires.
