Keyword seasonality
What is keyword seasonality?
Keyword seasonality is the predictable rise and fall in searches for a keyword at certain times of year. "Halloween costumes" peaks in October, "tax return deadline" around tax season, "sunscreen" in summer and "gym membership" in January. A seasonal keyword can have a modest annual average but very high demand for a few weeks.
Seasonality is hidden by monthly averages, so check a 12-month keyword trend or Google Trends to see it. Seasons differ by country and hemisphere: "summer dresses" peaks in December in Australia. Some patterns follow events rather than weather, like exams, sports tournaments, product launches and shopping days such as Black Friday.
Why keyword seasonality matters for SEO
Pages need time to be crawled, indexed and climb the rankings, so publishing a seasonal page during the peak is usually too late. Planning around seasonality means updating and promoting pages weeks or months before demand rises, while evergreen content can be published any time.
It also explains traffic changes. A drop in organic traffic in a slow season may be normal, not a ranking problem; compare year on year rather than month on month.
How to plan for seasonal keywords
- Check the 12-month trend of your important keywords to find peaks.
- Publish or refresh seasonal pages one to three months before the peak.
- Keep seasonal pages on a permanent URL (for example /black-friday rather than /black-friday-2026) so they keep their links each year.
- Update the content and dates before each season rather than creating a new page.
- Compare traffic and rankings year on year to judge performance.
Keyword seasonality example
A garden centre sees "christmas trees near me" go from almost nothing in summer to its yearly peak in late November and early December. It refreshes its Christmas tree page in October, on the same URL it has used for years.
Keyword seasonality FAQ
When should I publish seasonal content?
Usually one to three months before demand peaks, so the page has time to be indexed and rank. Refreshing an existing page with history is faster than starting a new one.
How do I find seasonal keywords?
Look at a keyword’s 12-month trend in a keyword tool or in Google Trends. A clear repeating peak each year means it is seasonal.
Related SEO terms
A keyword trend shows how searches for a keyword change over time, usually month by month, so you can spot growth, decline and seasonal peaks.
Search volume is the estimated number of times a keyword is searched per month in a given location, usually averaged over the past 12 months.
Evergreen content is content that stays relevant and useful for a long time, such as how-to guides and explainers, rather than news.
Content refreshWhite hat
A content refresh is a substantial update of an existing page to make it current, accurate and more useful, so it regains or improves rankings.
Content freshness is how recent and up to date a page is. Google ranks fresher content higher for queries where recency matters.
