Key takeaway: A seasonal keyword strategy for Bangladesh has to run on two clocks. Ramadan and both Eids follow the lunar calendar and arrive roughly 11 days earlier every year, while pre-monsoon heat and the monsoon stay in roughly the same months. Plan the lunar clock backwards from an expected date, plan the climate clock by month, and don’t reuse last year’s publish dates.
Your seasonal calendar has two clocks, not one
A common way to plan seasonal SEO is to find last year’s traffic spike and publish a few months ahead of it. That works when the spike sits in the same month every year. In Bangladesh, some of yours won’t.
Ramadan and Eid follow the lunar Hijri calendar, so they arrive about 11 days earlier each year. Ramadan began around 18 February in 2026 and is expected around 8 February in 2027, subject to moon sighting. The monsoon doesn’t drift like that: the Bangladesh Meteorological Department splits the year into pre-monsoon (March–May) and monsoon (June–September) periods, and although the onset varies, the months hold.
| Clock | Anchors | How it moves | Planning rule |
|---|---|---|---|
| Lunar | Ramadan, Eid-ul-Fitr, Eid-ul-Adha | Roughly 11 days earlier each year; confirmed by moon sighting | Plan backwards from the expected date |
| Climate | Pre-monsoon heat, monsoon | Same months each year; onset varies | Plan by month and watch the onset |
This two-clock model is my own planning framework, not an industry standard. It explains why a calendar borrowed from elsewhere fails quietly: it assumes every peak sits on a fixed date.
Plan backwards from a moving date, not forwards from last year
Take the expected start date and count back through three windows.
- Research (about 12 to 10 weeks before): check which seasonal queries exist for your service using Google Trends and manual SERP checks. No paid tool? Find keyword gaps without one.
- Build (about 10 to 8 weeks before): publish or update pages early enough to be crawled and indexed.
- Peak (the final weeks): monitor, update hours and offers, and avoid rebuilding pages mid-peak.
These timings are my recommendation, not a measured rule. As a regional benchmark, Microsoft Advertising’s Ramadan 2024 data shows preparation beginning up to eight weeks before Ramadan across Southeast Asia and the Middle East and Africa. Check it against your own Search Console history.
Here is the arithmetic for 2027. Ramadan is expected around 8 February, so pages should be live by mid-December 2026 and research should start by mid-November. Eid-ul-Fitr is expected around 9–10 March, with Eid-ul-Adha in mid-May.
Ramadan and Eid are a sequence of intents, not one spike
You might assume “Ramadan keywords” means one peak. It is more likely a sequence of different needs, and each calls for a different page. Treat these as hypotheses to test, not findings:
- Before Ramadan: preparation jobs such as deep cleaning, appliance servicing and repainting.
- Early Ramadan: changed routines and opening hours, plus iftar searches for food businesses.
- The last ten days: last-minute bookings before Eid.
- The Eid break: many providers close, so “open on Eid” searches may appear.
- After Eid-ul-Adha: clean-up and pest-related queries.
The two Eids also differ. Eid-ul-Fitr closes a month of preparation, so planning queries build before it. Eid-ul-Adha centres on the Qurbani, which may create clean-up demand afterwards. Check each in Trends separately instead of treating Eid as one event.
If you run a cleaning business, the SEO approach for cleaning services covers the evergreen base. Seasonal pages then sit on top of it, one per phase that genuinely changes the buyer’s urgency.
Heat and monsoon demand starts planned, then turns reactive
Before the season, people search for planned jobs: AC servicing, waterproofing, wiring checks. Once the heat or rain arrives, reactive searches take over: AC not cooling, roof leaking, power tripping.
Those are two intents, and I’d give them different pages. Guide-style pages suit planned jobs that lead the peak by weeks, and fast-contact service pages suit reactive jobs that arrive with it. It is the same logic as buyer keywords versus research keywords, applied to a calendar.
The practical result is a pair for each service: one planned-intent guide that goes live early, and one service page ready for reactive traffic before the season turns.
The clocks can also collide. Eid-ul-Adha is expected in mid-May 2027, inside the pre-monsoon window, so an AC business could face peak heat demand and holiday closures in the same weeks.
Which businesses should test which seasons
| Business | Likely trigger | Search type likely to lead |
|---|---|---|
| Home cleaning | Before Ramadan and Eid | Planned: deep cleaning |
| AC and HVAC | Pre-monsoon heat | Planned servicing, then reactive repair |
| Pest control | Monsoon | Reactive |
| Plumbing and electrical | Monsoon | Reactive: leaks, tripping |
| Restaurants | Ramadan | Iftar and timing queries |
Treat every row as a hypothesis and check it in Google Trends before building a page. Also test Bangla, Banglish and English versions of each term, since the language people search in may shift at peak moments.
Where seasonal keywords belong on your site
Add them to the keyword map you already have instead of starting a separate seasonal section. A local keyword map shows which page owns each term, and seasonal terms join it as a layer. If the seasonal intent matches the evergreen page, add a section there. If it clearly differs, such as an iftar menu versus a general restaurant page, it may deserve its own URL.
Update your Business Profile before the peak
Google’s post on Ramadan business tools covers updating Ramadan timings and seasonal offers. It is written for the Middle East, but the habit carries over: check special hours before the first day of Ramadan and again before each Eid.
Seasonal posts and photos belong in the same routine, as in hyper-local GBP content.
Write seasonal pages so the answer can be quoted
Seasonal searches are often questions: when to service an AC before summer, how to prepare a home for Ramadan. AI assistants and AI summaries may answer them directly, so a page that states the timing plainly, with the reason in the next sentence, is easier to quote. Put the direct answer first, add the dates, and label anything uncertain as expected rather than confirmed, since moon sighting can shift a date by a day.
Compare Ramadan with Ramadan in Search Console
Year-over-year comparisons help separate seasonal dips from real ranking problems, but only when the dates line up. Ramadan 2026 ran roughly from 18 February to 19 March. Compare those dates with the same dates in 2027, and the first ten days of Ramadan 2027 fall outside the window while days after Eid fall inside. The result can look like a decline that isn’t one.
Compare each Ramadan and each Eid week with its predecessor, and check non-seasonal pages over the same period.
What I’d check before building any seasonal page
Three questions come first. Does this business’s demand follow the lunar clock, the climate clock, or both? Is the search planned or reactive? Can the business actually serve extra demand with its hours, staff and stock?
The third question is the one people skip. A seasonal page that sends reactive searchers to a business closed for Eid can cost more trust than it earns clicks. In that case I would update the hours first, publish later, and accept a smaller peak.
My recommendation
Build two calendars, one lunar and one climate, and plan each backwards from its expected peak. Start research about 12 weeks ahead, publish about 8 to 10 weeks ahead, and adjust those numbers against your own Search Console data. Label each query as planned or reactive, confirm demand in Google Trends first, update your Business Profile hours before each peak, and compare every season only with the matching season of the previous year.
