Reach and Frequency Buying
Paid MediaAlso: R&F Buying · Reach and Frequency Campaigns
Quick definition
Reach and frequency buying is an advertising purchase method where you pay for a set number of people to see your ad a set number of times, rather than bidding in real time for clicks or conversions. Platforms like Meta and YouTube offer it for planned, fixed-budget brand campaigns.
How it varies across Australia
Reach and frequency buying is used far less often across Australian advertisers than auction buying, mostly because it needs a larger committed budget and audience size to unlock. Where it does show up, it clusters in retail and finance brand campaigns run around fixed calendar moments.

Most paid media runs on an auction. You set a goal, a budget and some guardrails, and the algorithm bids for impressions in real time, chasing whatever outcome you told it to optimise for. Reach and frequency buying works differently. You pick an audience size, a flight of dates and a frequency cap, then the platform delivers exactly that. No bidding, no algorithm chasing clicks. Just guaranteed delivery against a plan.
This matters because auction buying and brand-building don't always want the same thing. An auction optimised for conversions will happily show your ad to the same warm, high-intent slice of your audience twenty times a week if that's where the clicks are cheapest. That's efficient for performance metrics like CPA or ROAS, but it's a poor way to build awareness across a broad audience. Reach and frequency buying flips the priority. You decide the frequency cap. The platform spreads delivery to hit reach targets instead of chasing efficiency.
It sits closest to how a media planner would have bought a television campaign. Fixed dates, fixed audience, fixed exposure ceiling, priced up front. That predictability is the entire point, and it's also the tradeoff. You give up the algorithm's ability to chase performance in exchange for knowing exactly what you're getting.
Auction buying asks the algorithm to guess who should see your ad. Reach and frequency buying tells it exactly who, how often, and stops there.
How it shows up
Reach and frequency buying shows up as a separate buying type inside Meta Ads Manager and Google's video campaigns, usually gated behind a minimum audience size (often a million or more) and a minimum committed budget. It's planned in advance rather than adjusted daily. Reporting looks different too. Instead of daily CPA or click-through rate fluctuations, you'll see a delivery forecast up front and a reach curve tracking against plan, with frequency distribution as the main health check rather than conversion rate.
The Australian context
Australia's smaller population means reach and frequency buying hits its minimum audience thresholds faster relative to the total addressable market than it does in the United States. A campaign targeting all Australian adults in a major city can genuinely reach a meaningful share of that market within a short flight, which makes the buying method more viable here for national or state-level brand campaigns than the raw platform minimums might suggest.

Common questions
When should I use reach and frequency buying instead of auction buying?
Use it when your goal is broad awareness with a controlled frequency, not conversions. Fixed-flight brand campaigns, product launches and sponsorship-style bursts suit it. If you're chasing CPA or ROAS, auction buying will always be more efficient.
Does reach and frequency buying cost more than auction buying?
Not inherently, but it requires a larger minimum committed budget and audience size to unlock. The cost per impression is often comparable, the difference is you're buying predictability and delivery control rather than bidding for the cheapest available impression.
Which platforms offer reach and frequency buying?
Meta Ads Manager offers it for Facebook and Instagram campaigns above a minimum audience threshold. Google offers a similar guaranteed delivery option for YouTube video campaigns. Both require planning the flight and audience in advance rather than adjusting daily.
Can I optimise a reach and frequency campaign for conversions later?
No. The buying method is fixed for the life of that campaign. If your objective shifts toward performance, you need to pause it and run a separate auction-based campaign optimised for that goal instead.
