Running successful Facebook ads today isn't just about creatives, budgets, and offers. The technical setup behind your campaigns can make or break everything — especially if you’re in traffic arbitrage or running multiple accounts. Without the right foundation, your campaign could get banned within hours of launch.

In this guide, we’ll break down real-world mistakes that can ruin your campaigns before the first click.

Warming up accounts: don’t launch ads right away

If you’re using a new or rented account, patience is key. Your profile needs to look like a real person to Facebook’s automated systems. In practice, warming up a completely fresh account can take 1–2 months. For semi-warmed accounts with an established persona, 2–4 weeks may be enough.

A proper warm-up strategy includes:

• Creating the account using a personal IP address.
• Mimicking natural user behavior: posting content, liking, commenting, adding friends, joining groups.
• Running small, low-budget ad campaigns.
• Always using clean, dedicated IPs.

Taking the time to do this right builds trust, prevents account bans, and helps your offers run smoothly. It’s better to warm up slowly than to lose an account mid-campaign.

Proxies: your first line of defense

Managing multiple accounts from one IP is a fast track to a ban. Facebook’s system flags such activity as suspicious and often responds with forced verification — or worse, a complete block.

A reliable solution is using proxies to mask your real IP and create a unique online environment for each account. But even with proxies, there are rules to follow:

• Avoid public or low-quality paid proxies — they’re easily flagged.
• Use dedicated IPv4/IPv6 or mobile proxies — these look natural and trigger fewer red flags.
• Make sure your proxy’s geolocation matches your account’s location — mismatches can trigger manual reviews.

Proxyline lets you choose the exact IP type and location (HTTP/SOCKS5), so you can stay agile and adapt to Facebook’s ever-changing rules.

Anti-detect browsers: non-negotiable for multi-account ads

If you’re running multiple accounts, you need to isolate each one. Facebook tracks everything:

• Browser fingerprint
• Cookies
• Regional settings
• Even screen resolution

Anti-detect browsers (like AdsPower, Dolphin, Incogniton) isolate each session and spoof device fingerprints. Combined with proxies, this helps avoid bans and access geo-restricted content safely. Just remember to regularly update browser profiles and proxies to prevent suspicious patterns.

Tracking, pixels & technical footprints

Facebook doesn’t just monitor user behavior — it tracks scripts and tracking tools, too. Poor tracking setup can tank your Ads Manager reputation.

To stay in the green:

• Use trusted trackers like RedTrack, Binom, or Voluum.
• Set up your Facebook Pixel correctly.
• Avoid redirect chains that pass through shady domains.
• Routinely audit all scripts and integrations for safety and compliance.

Final Thoughts

The tech side of Facebook Ads matters just as much as your creatives or targeting. Misconfiguration of your proxy, anti-detect browser, or tracker can wipe out your entire setup.

Here’s a quick checklist for safe ad launches:

1. Use stable, geo-targeted proxies like Proxyline.
2. Warm up accounts before running any serious ads.
3. Isolate every account with an anti-detect browser.
4. Keep your tracking setup clean and compliant.

In digital marketing, it’s not always the most creative who win — it’s those who master the backend tech. Attention to detail is the secret to scaling smoothly and winning long-term on Facebook Ads.
