Advertising Platforms · 2026 reliability ranking

Most Reliable Advertising Platforms (2026)

We ranked 12 ad platforms by real-world reliability over the last 90 days, using 17 status page incidents and our own around-the-clock uptime checks. A small business running paid ads depends on the platform to serve them, count conversions and report spend accurately. When ad delivery, the campaign editor or conversion tracking fails, budgets can be spent on ads that never show, campaigns cannot be paused or changed during a promotion, and automated bidding learns from missing data. Reporting delays are common and easy to miss, so checking a platform's incident history shows how often the numbers you optimise against are late or wrong.

Advertising Platforms reliability at a glance

  • Across the 7 ranked ad platforms, average 90-day uptime is 99.45%. Reliability scores range from 100.0 (AdRoll) to 46.1 (Criteo).
  • Together they published 17 incidents in the last 90 days, 5 of them partial or major outages.
  • AdRoll, Pinterest Ads, Reddit Ads reported no incidents at all in that time.
  • The typical vendor takes 17h 5m to resolve an incident. Meta Ads is fastest, at 1h 36m on average.
  • Criteo reported the most incidents (7 in 90 days).

What to check before you choose a ad platform

  • Separate ad delivery and conversion tracking from reporting. Delivery or pixel outages waste spend; a reporting delay usually only postpones decisions.
  • Check whether the platform posts incidents for its ads products specifically, or only for the consumer app, so you know where to look when results drop.
  • Avoid making big budget or bidding changes while the platform reports delayed or incomplete data, since automated bidding will act on it.
  • Run important campaigns on more than one platform so a single outage during a launch or sale does not stop all paid traffic.

Frequently asked questions

What is the most reliable ad platform?

Based on the last 90 days of data, AdRoll is the most reliable ad platform we track, with a reliability score of 100.0/100 and 100% uptime.

How do you measure ad platform reliability?

We poll each vendor's public status page every few minutes, record every incident, and run our own uptime checks against each vendor's login and customer-facing pages. Uptime (40%), incident frequency (20%), average time to resolve (20%) and transparency (20%) combine into one score out of 100.

How often are these rankings updated?

Continuously. Status pages and uptime checks run every five minutes and scores are recalculated several times an hour.

Can vendors pay to rank higher?

No. Sponsored placements are clearly labelled, shown separately from the rankings and never change a vendor's score.
