Cost per lead comparisons between search and social often miss the point, because the two channels do different jobs. Search ads capture demand that already exists — someone typed a query because they had already decided, on their own, that they had a problem worth solving right now. Social ads create demand — they interrupt a feed nobody was searching, and introduce a problem or a solution the viewer hadn't been actively looking for. Judging one against the other's metrics, as if they were competing for the same job, is how budgets get misallocated.
What actually decides the split
The right split isn't a fixed percentage industry benchmark — it follows from how the purchase decision itself gets made. A need that's urgent, specific and already understood by the buyer — an emergency repair, a service searched by name, a product compared by spec — is usually decided before the ad is ever seen, which is exactly what search is built to capture. A need that's considered, visual, or socially influenced — interior design, aesthetic treatments, a new restaurant, a fashion brand — is often decided during exposure rather than before it, which is what social is built to create.
A simple test: does the query already exist?
Check search volume for the core need in the target market before assuming a channel split. If people are already searching a meaningful volume of queries related to what's being sold, search deserves budget priority, because it's converting someone who arrived at the decision independently — the cheapest kind of conversion to earn. If search volume for the specific need is thin or effectively nonexistent, no amount of search budget will find buyers who aren't typing the query yet, and social has to do the harder work of creating the decision before anyone would think to search for it.
Where the two channels actually meet
A viewer sees a social ad, doesn't click, and searches the brand name a week later once the decision has firmed up. That conversion shows up as a search win in most reporting, but it originated with the social exposure. Without checking assisted conversions or a lift in branded search volume against the social campaign's timing, it's easy to defund the channel that created the demand in favour of the one that merely collected the credit for capturing it — which starves demand creation and eventually starves search too, once there's nothing new for it to capture.
A realistic split, not an even one
For most small and mid-sized businesses, the honest starting point is: search gets the budget for anything with existing, identifiable search volume tied to a clear buying moment, and social gets the budget for building awareness in categories where demand has to be created before it can be captured — a new offering, a new location, a brand nobody is searching for yet. The ratio shifts over time as social exposure builds branded search volume that search can then capture more cheaply than social could convert directly.
The practical takeaway
Before setting a media split, map the actual buying decision: is this something someone already knows they need and would type into a search bar today, or something they'd only want once they've seen it? That answer, not a rule of thumb, decides where the next dirham of budget should go.
Matching channel to decision is one part of the wider paid advertising strategy a business needs before spend scales — objective and offer have to be settled before channel mix can be judged fairly. Where the split isn't obvious, our marketing team can model the buying decision and build the search-and-social mix around it rather than guessing at an industry average.
