Seasonal Keyword Planner#

Introduction#

Knowing when shoppers search is as valuable as knowing what they search for. Demand for most ecommerce keywords is not flat — it rises and falls on predictable seasonal curves, and the sellers who pre-position before a peak win cheaper clicks and higher organic rankings than those who react after traffic has already arrived. This skill maps each target keyword against a twelve-month demand curve, identifies peaks, shoulder seasons, and troughs, and turns that into a concrete month-by-month action plan for listing optimization, ad budget pacing, and content publishing.

The output separates evergreen keywords (steady year-round) from seasonal spikes (which require precise timing), and flags early-mover windows — the two-to-four weeks before a peak when search interest is climbing but competition is still low. That window is where the leverage is.

What this skill solves#

• Reacting too late — optimizing a listing or launching ads after demand has already peaked, paying premium CPCs for traffic everyone else is also chasing.
• Flat-budget waste — spreading ad spend evenly across 12 months when demand is concentrated in a few.
• Missed early-mover windows — failing to capture the low-competition ramp before a seasonal surge.
• Content that ranks too late — publishing gift guides or comparison posts at the peak, when they need 4–6 weeks to climb the SERP.
• Confusing evergreen with seasonal — over-investing in steady terms during their (nonexistent) "season," or under-investing in true spikes.
• Keyword cannibalization — multiple listings/pages competing for the same seasonal term.
• No shared calendar — merchandising, ads, and content teams working off different timelines.

Workflow#

1. Gather inputs. Confirm the keywords list (5–30 terms) and the product_category. Capture the target_markets (seasonality differs by hemisphere and country) and any known launch or promo dates.

2. Classify each keyword. Tag every term as evergreen, seasonal, or event-driven (tied to a specific retail moment). See references/seasonality-methodology.md.

3. Plot the demand curve. For each seasonal/event term, identify peak month(s), the rising shoulder, the falling shoulder, and the trough. Base this on multi-year patterns and the retail calendar in references/ecommerce-seasonal-calendar.md — and clearly mark where a pattern is assumed vs evidenced.

4. Find the early-mover window. For each seasonal term, mark the 2–4 weeks before the rise where prep should happen.

5. Build the month-by-month plan using references/output-template.md: for each month, what to optimize, where to move ad budget, and what content to publish — keyed to specific keywords.

6. Coordinate to avoid cannibalization. Group overlapping keywords so listings and content target distinct intents rather than competing.

7. Add lead times and a measurement note, then run assets/quality-checklist.md.

Inputs#

• keywords (required): 5–30 target keywords or phrases. Example: "fleece jacket, packable down jacket, rain shell, hiking base layer."
• product_category (required): The category these keywords sit in, used to anchor the seasonal pattern. Example: "outdoor apparel."
• target_markets (optional): Countries/regions; seasonality flips between hemispheres. Defaults to US.
• known_dates (optional): Planned launches, restocks, or promotions to align the plan around.
• channels (optional): Where the plan applies — Amazon SEO, Google Shopping, TikTok Shop, organic blog. Defaults to all relevant.

Worked example 1 — Outdoor apparel (US)#

Inputs: keywords = "packable down jacket, rain shell, hiking base layer, fleece jacket"; category = outdoor apparel; market = US.

Classification & curve (excerpt):

• packable down jacket — seasonal, peaks Oct–Dec (cold-weather + gifting). Rising shoulder Sep; trough May–Jul. Early-mover window: late Aug–early Sep.
• rain shell — seasonal, two peaks: Mar–Apr (spring rain) and Sep (back-to-trail).
• hiking base layer — seasonal, peaks Oct–Nov; gift-driven secondary bump in Dec.
• fleece jacket — near-evergreen with a lift Sep–Jan.

Plan excerpt:

August: refresh packable down jacket listing copy + images; publish "best packable jackets" guide (needs lead time to rank by Oct). September: shift ad budget toward down jacket and base layer; capture the early-mover window before competitors. October–December: peak — maximize bids on down jacket, base layer; run gift-guide content. May–July: trough — pull down jacket spend, redirect to spring/summer terms; keep fleece evergreen presence.

Why it works: prep happens in the low-competition window, content is published with time to rank, and budget follows the curve instead of fighting it.

Worked example 2 — Home fitness (US + AU)#

Inputs: keywords = "adjustable dumbbells, resistance bands, yoga mat, home gym setup"; category = home fitness; markets = US + Australia.

Key insight surfaced: New-Year resolution demand spikes late Dec–Jan in both markets, but Australia adds a secondary Jun–Jul lift (Southern-Hemisphere winter, indoor training). The plan therefore double-weights adjustable dumbbells and home gym setup prep in early December (for the Jan peak) and again in late May for the AU winter, while yoga mat trends closer to evergreen with a January bump.

Why it works: it catches that the same keyword has different curves per hemisphere, so the AU plan isn't a copy of the US plan.

Common mistakes#

1. Optimizing at the peak instead of before it. Listings and content need lead time; arriving at the peak means arriving late.
2. Treating every keyword as seasonal (or none as). Misclassification wastes budget. Tag evergreen vs seasonal explicitly.
3. Even ad spend across the year. Concentrate budget where the demand is.
4. Publishing content too late to rank. Allow 4–6 weeks for SEO content to climb before the peak.
5. Copying one market's calendar onto another. Hemispheres flip; holidays differ. Plan per market.
6. Ignoring the early-mover window. The cheap-click, low-competition ramp is the highest-leverage period.
7. Self-cannibalization. Multiple pages chasing the same term split authority. Coordinate intent.
8. Assuming a peak from the calendar without evidence. Mark assumptions; validate with real volume data where available.
9. One-and-done. Seasonality shifts; revisit the plan each quarter.
10. No measurement loop. Without tracking rank/CPC by month, you can't tell if pre-positioning worked.
