Real-Time Bidding for Job Ads

Q: Does Expertini run real-time bidding auctions for job ads?

Not for the Programmatic Job Ads tool — that's a fixed-rate CPC purchase against Expertini's own network. The Google Ads Connector and Microsoft Ads Integration do enter real auctions, but those are Google's and Microsoft's own ad platform auctions, not one Expertini operates.

Q: How fast is a real RTB auction cycle?

Commonly cited at under 100 milliseconds for the full cycle, achievable because bidding uses pre-computed relevance and CTR estimates rather than live calculation during the auction itself.

Q: Is "AI bidding" always a trained machine-learning model?

Not necessarily. The term covers a real range from genuinely trained, continuously-updated models to simpler fixed heuristics marketed with AI language — worth asking what data a specific platform's model is actually trained on before taking the claim at face value.

Q: If I run a Google Ads campaign through Expertini, is that entering a real auction?

Yes — once submitted through the OAuth connector, the campaign runs inside Google's own advertising auction like any other Google Ads campaign, subject to Google's own Smart Bidding and auction mechanics.

What RTB actually is, and where it does — and doesn't — show up in Expertini's ad tools.

3 min read · Updated July 2026 · Expertini Editorial

Real-time bidding (RTB) is a specific mechanism — an automated auction, completed in roughly the time it takes a page to load, that decides which advertiser's ad fills a given impression. It's a real and well-documented piece of ad-tech infrastructure. It's also a phrase that gets attached to recruitment products more loosely than the mechanism itself would justify, so this page explains what RTB actually does, and states plainly where it applies to Expertini's own tools and where it doesn't.

01How an RTB auction actually works

When ad inventory becomes available — a job seeker loads a search results page, say — a bid request goes out to connected demand-side platforms with a tight deadline, commonly cited around 100 milliseconds for the full cycle from request to winning bid. That speed is only possible because bidding decisions use pre-computed relevance and predicted click-through estimates built ahead of time, not live calculation during the auction itself; the actual machine-learning work happens between auction cycles, updating those pre-computed models from accumulated performance data.

02Why "AI bidding" claims deserve some scrutiny

"Our AI optimises your bid in real time" appears in a lot of programmatic advertising marketing, and its concrete meaning varies a lot between platforms — sometimes it's genuinely a trained model updating relevance scores from real outcome data, sometimes it's closer to a fixed heuristic dressed up in AI language. Neither is dishonest by itself, but the distinction matters if you're evaluating a platform's claims: the useful question isn't whether AI is involved, it's what data the model was actually trained on and how often it updates.

03What Expertini's Programmatic Job Ads tool does instead

It does not run an RTB auction against external ad exchanges. It's a fixed-rate, pay-per-click purchase against Expertini's own owned network — you buy a click package, and delivery is tracked against that order. There's no per-impression auction against other advertisers' bids happening on Expertini's side, and no claim to that effect should be inferred from the word "programmatic" in the tool's name.

04Where auction-based buying does apply to these tools

It applies on the Google Ads Connector and Microsoft Ads Integration — because those campaigns run inside Google's and Microsoft's own ad platforms, they genuinely do enter each platform's real advertising auction once submitted, subject to those platforms' own Smart Bidding and auction mechanics. That's real RTB-adjacent infrastructure, just owned and operated by Google and Microsoft, not by Expertini.
