Using your audiences in Reddit Ads

Updated by Dag

Reddit syncs directly from ContactLevel, the same way as LinkedIn, Meta and Google. Once synced, your audience appears in Reddit Ads Manager as a custom audience you can target at ad group level. No CSV export or upload needed.

Sync your audience to Reddit

  1. Connect Reddit under Integrations → Connections → Reddit Audiences if you haven't yet. See Connecting your ad accounts.

  2. Open your audience and click Syncs.

  3. Click Run next to Reddit Ads.

The status changes to Synced. Reddit can take up to 72 hours to finish matching, and the Est. match rate updates once it does.

Target the audience in Reddit Ads Manager

  1. In Reddit Ads Manager, create or edit a campaign and open the ad group.

  2. In the audience targeting section, select the custom audience with the same name as your ContactLevel audience.

  3. Finish the rest of your ad group settings and launch.

You can use the audience across Reddit's placements, including the home feed, subreddit feeds and conversation pages.

Why Reddit matches work differently

Reddit users sign up with personal emails and pseudonymous accounts, so work emails rarely match. ContactLevel's enrichment adds personal identifiers like personal emails, phone numbers and device IDs, which is what Reddit can match on. Match rates on Reddit are still lower than on LinkedIn or Meta. Watch the matched count, not just the percentage.

Audience size

  • Minimum: 1,000 matched users. Below that, the audience may show as "invalid" in Reddit Ads Manager.

  • Recommended: 5,000–10,000+ matched users for stable delivery.

Keep the audience up to date

When you add contacts to the audience in ContactLevel, open Syncs and click Run again. The Reddit audience updates in place, so your ad groups keep targeting it without changes.

Track visits from Reddit ads

  1. Install the tracking pixel on your website.

  2. Copy your audience's cl_audience parameter.

  3. Add it to each Reddit ad's destination URL. See Adding UTM params to Reddit ad campaigns.

Tips

  • Test your audience on its own against your audience plus subreddit targeting to see which works better.

  • Use "awareness" or "traffic" objectives to reach more of the audience.
