How Demand Gen works
Demand Gen is a Google Ads campaign type that places image and video ads across YouTube, YouTube Shorts, Gmail, Discover and the Display network. It is audience-led rather than keyword-led: nobody has typed anything, so you describe who you want to reach instead of what they searched for. Targeting comes from your own customer lists, lookalike segments built from those lists, and Google’s interest and in-market audiences.
You supply assets — images in several shapes, short video, headlines, descriptions and a logo — and Google assembles them into the formats each surface accepts. Bidding is automated, usually towards conversions, conversion value or clicks, and the reporting looks closer to a social platform’s than to the keyword detail of search. It replaced Discovery campaigns, adding YouTube in-stream and Shorts inventory, lookalike audience controls, and previews of how a creative will render on each surface.
Why Demand Gen matters
Search only reaches people who already know what to ask for. For a product or a service most people have not heard of, there is no search volume to buy, and the choice is between creating the demand or waiting for someone else to. Demand Gen is Google’s answer to that, and it behaves far more like Meta advertising than like search advertising.
It also reaches inventory that is genuinely hard to buy any other way. YouTube and Discover hold a great deal of attention in mobile-first markets like Nepal, where much of the audience meets the internet on a phone and spends its time in feeds rather than on results pages.
Where Demand Gen goes wrong
Expecting search economics is the first mistake. The click is cheaper and the intent is weaker, so a cost per lead can look attractive while the leads themselves are colder and slower to close. Held to the same conversion window as a search campaign it will always look worse than it is; held to nothing at all it will absorb budget quietly for months.
The second problem is creative. This is a channel where the asset does most of the work, and a repurposed web banner or a landscape video squeezed into a vertical feed gets scrolled past. The third is measurement: with no search to anchor it, attribution is harder, and view-through credit needs to be understood by everyone before it appears in a report.
How to act on it
Start with the audience you can prove. A customer list, recent site visitors and people who have watched your videos are a firmer foundation than a broad interest segment, and they give the lookalike models something real to learn from. Build creative for the surface — vertical video for Shorts, a single clear message for Discover — rather than adapting whatever already exists.
Agree before launch what success means, because a cheaper lead is no gain if those leads do not close. Measure over a longer window than search, keep the results separate in reporting rather than blended into one account-wide cost per lead, and read how Demand Gen campaigns sit alongside search and Shopping before deciding where the budget comes from.
