Helium 10 Trendster: Retired in 2025, and How to Check Seasonality Now

Tutorial By Updated

Helium 10 retired Trendster. Its help center says Trendster, Misspellinator and Inventory Protector were “officially sunset” effective 30 September 2025 and “are no longer available within the platform” (checked 10 October 2026). To check seasonality inside Helium 10 now, use the search-volume history graph in Cerebro, which can show Amazon or Google data, or the sales and rank history graphs in Xray and Black Box.

Correction (10 October 2026): an earlier version of this page described Trendster as a live free tool that Helium 10 now lists as Amazon Trending Products. Helium 10 retired Trendster on 30 September 2025, and Amazon Trending Products is a different tool.

What Trendster did

Helium 10 marketed Trendster as an “Amazon Price Trend Tracker”. Its product page, last saved by the Internet Archive in December 2022, said it let you “compare up to four ASINs with their top keywords”, hover over a price and sales graph, and see Google Trends data next to Amazon sales rank. The same page listed it on the plans of the time: Starter (limited use), Platinum and Diamond.

That product page now redirects to Helium 10’s product research overview (checked 10 October 2026). Our Helium 10 features guide lists the product research tools Helium 10 sells now.

Helium 10’s free Amazon Trending Products tool shows “the top sellers in any Amazon category”, with estimated monthly sales and revenue for top products and trend indicators (checked 10 October 2026). It ranks today’s best sellers within a category. It doesn’t chart one product’s price and sales rank across the year the way Trendster did.

How to check seasonality in Helium 10 now

  • Cerebro search-volume history. Anywhere Cerebro shows a search volume, a graph icon opens that keyword’s history. Helium 10’s help center (updated 20 November 2025) says you can change the timeframe, switch the source between Amazon and Google, and download the data. A keyword whose volume climbs every November says more about a product’s season than one month’s figure. Our keyword search history guide explains the graph in detail.
  • Xray sales and rank graphs. In the Chrome extension, Xray’s Sales Graph, BSR and Review Count columns open history charts for each product with adjustable timeframes, according to Helium 10’s Xray guide (edited 9 April 2026). That is the closest match to Trendster’s sales-rank chart.
  • Black Box product graphs. Helium 10’s Black Box guide says its results include graphs of best-seller rank, price history and sales history for each product.
  • Diamond’s long-term keyword trends. The Diamond card on Helium 10’s pricing page lists “Long-term keyword trend analysis for seasonality and growth planning” (checked 10 October 2026). Platinum’s card doesn’t.
  • Inventory forecasts for products you already sell. Helium 10’s help center (updated 3 June 2026) says its Additive forecasting model “accounts for product seasonality” and is meant for products that have sold for more than a year.

For regular use these tools need a paid plan: Helium 10’s help center lists Cerebro as unavailable on its limited free account, Black Box at 5 lifetime uses, and Xray as limited. Our Cerebro guide covers Platinum’s 100-search monthly cap.

Free ways to check seasonality

  • Keepa: its price-history charts are free in the browser extension, and Keepa Pro costs €29 a month or €290 a year (checked 10 October 2026). Our Helium 10 vs Keepa comparison covers where each fits.
  • Google Trends: free, and useful for search interest outside Amazon, but it doesn’t show Amazon search volume or sales.
  • The Helium 10 Chrome extension: free to install, with demand, revenue and trend signals on Amazon product pages, according to Helium 10’s extension page. Full access needs Platinum or above; see our Chrome extension guide.

How to read seasonal data

  • Look at a full year at least, and two if the data goes back that far. A single spike can be a promotion or a competitor’s stock-out rather than a season.
  • Compare keyword demand with product sales rank. Demand that rises at the same time every year is seasonal; a one-off jump isn’t.
  • Remember that Helium 10’s search volumes and sales figures are its own estimates; our guide to how Helium 10 gets its data explains what comes from Amazon and what is modelled.

Frequently Asked Questions

Is Helium 10 Trendster still available?

No. Helium 10's help center says Trendster, Misspellinator and Inventory Protector were sunset effective 30 September 2025 and are no longer available within the platform.

Is Amazon Trending Products the same as Trendster?

No. Amazon Trending Products is a free Helium 10 tool that lists top-selling products by Amazon category with estimated monthly sales. Trendster charted up to four products' price and sales rank over time and compared them with Google search interest.

How do I check if a keyword is seasonal in Helium 10 now?

Run the keyword or a competitor's ASIN in Cerebro and click the graph icon next to the search volume figure. Helium 10's help center says the history can be viewed over different timeframes, switched between Amazon and Google data, and downloaded.

Is there a free way to check Amazon seasonality?

Partly. Keepa's price-history charts are free in its browser extension, and Google Trends is free for search interest, but neither shows Helium 10's keyword search-volume estimates.
