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.

Do and do not

Do

  • Map your own peaks from your own enquiry history
  • Start campaigns and content ahead of each peak
  • Check the team can serve the demand you buy

Do not

  • Judge a seasonal month against the month before it
  • Lift budgets sharply on the busiest morning
  • Assume your business has no seasonal pattern

Questions people ask about this

How do I know whether a drop is seasonal or a real problem?

Compare the period with the same period last year rather than with last month, and check whether the same dip appeared then. Look at search demand for your main terms as well: if the whole market fell, the cause sits outside your account. If your figures fell while demand held steady, something in the campaign, the site or the tracking has changed.

Should I stop advertising in the off-season?

Rarely all the way to zero. A quiet period is cheaper to buy in, which makes it good ground for building remarketing audiences, testing creative and publishing content that will be ranking by the time demand returns. Reduce the budget to match demand instead of switching off, because restarting cold means learning the account again just as the peak arrives.

Does seasonality affect SEO as well as ads?

Yes, though it moves more slowly. Rankings do not swing with the season, but the number of people searching does, so the same position delivers less traffic in a quiet month. The practical difference is timing: content and technical work take weeks to earn their position, so seasonal pages need to be published and indexed well before demand arrives.
