How seasonality works
Seasonality is the repeating shape of demand across a year. It comes from things that happen on a calendar rather than because of anything you did: festivals, weather, school and university intakes, salary dates, financial year ends and public holidays in the countries your customers live in.
In Nepal that shape is unusually pronounced. Dashain and Tihar move both spending and staffing; the monsoon and the clear autumn months split the trekking and travel year in two; admission seasons concentrate enquiries for education consultancies into a few weeks; and remittance-driven spending follows the pay cycles of the countries where family members work. A business also selling into Australia or the UK carries a second calendar on top of the local one.
Why seasonality matters
Without it, ordinary reporting misleads. A drop that is really the monsoon reads as a failing campaign, and a rise that is really the festival period reads as proof that last month’s changes worked. Comparing a period with the one before it is the quickest route to the wrong conclusion; comparing it with the same period last year removes most of the illusion.
It also decides when money is worth spending. Budget held back during a peak is demand handed to a competitor, and budget pushed hard in a trough buys clicks from people who were not going to buy yet.
Common mistakes with seasonality
The first is assuming a business has none. Most have some, in a milder form: enquiries that sag at month end and recover after payday, or a weekly rhythm that is really a working-week effect.
The second is reacting to a peak once it has started. Search demand rises before the event itself, sometimes well before, so changes made in the middle of a rush arrive late. Automated bidding also needs time to settle after a sharp change, which means budget lifted on the busiest morning may not deliver until the wave has passed. The third is forgetting that supply is seasonal too — there is little point buying demand for a week when the team is on holiday and nobody is answering the phone.
How to act on it
Build a calendar of your own year from your own data. Pull enquiries and revenue by month for as far back as you have them, mark the festivals, intakes and holidays, and note which swings repeat. Then plan budget and content against that calendar instead of in equal monthly slices, and start ahead of each peak so bidding and content have settled before the demand lands.
Where a peak is genuinely large, tell the ad platforms about it in advance rather than letting them discover it, and leave the ordinary targets alone for the rest of the year. Managing that calendar alongside the spending is much of what day-to-day performance marketing involves.
