EC-Tracking is a Chrome extension provided by 株式会社アイコンコーポレーション. It is positioned as a search ranking tracker for three major Japanese e-commerce marketplaces: 楽天市場, Amazon, and Yahoo!ショッピング. It targets the inefficient workflow in e-commerce operations where teams repeatedly search keywords manually and record their own and competitors’ rankings, automatically turning daily rankings into charts, snapshots, and email alerts.
The tool accesses each marketplace’s search pages through the user’s browser and captures the search result rankings for registered keywords. It states that 楽天RPP, Amazonスポンサー, and Yahoo!ショッピング ads are excluded, so only organic rankings are recorded. Each marketplace can be tracked up to position 90. Features include automatic collection once per day, trend charts for positions 1–90, store code/ASIN registration, competitor comparison, keyword grouping, ranking snapshots, CSV export, and browsing of marketplace category rankings. The Pro plan and above add ranking-change threshold alerts, daily emails, and device cloud sync; Business adds Yahoo!「売れてる順」 tracking, weekly summary emails, and 365-day data retention.
The Free plan is free and can track 3 keywords, 2 groups, and 1 store/3 ASINs, with charts retained for 30 days, making it suitable for validating the workflow. Pro costs ¥1,480/month, increasing the allowance to 50 keywords and 180 days of data, while adding alerts and sync. Business costs ¥2,980/month; during the launch period, the first 200 users get the first 3 months at ¥2,384/month, making it suitable for teams tracking around 100 keywords. Enterprise starts from ¥19,800/month and offers custom limits, dedicated support, custom development, SLA, and multi-account management. Payments are handled by credit card via ExtensionPay/Stripe.
Its strengths are a focused use case, easy onboarding, and low pricing. Even the Free plan includes automatic collection and CSV download. By excluding ads and tracking organic rankings, it is more useful for evaluating SEO impact. Comparing competitor stores/ASINs on the same chart also makes it easier to assess the effects of optimization measures. The main limitation is that it is not a fully cloud-based crawler: the PC must be powered on and Chrome must be running; if it is not running, data collection requires manual handling after the next launch. In addition, the terms state that rankings are reference values, and changes to marketplace specifications may affect availability.
It is best suited to brands, stores, agencies, and small to midsize EC teams operating Japanese e-commerce channels, for use in keyword daily reports, competitor monitoring, and before/after reviews of advertising or SEO initiatives. For Chinese merchants, if the business focus is 楽天, Amazon Japan, or Yahoo!ショッピング, it can serve as a lightweight tool. If data is needed for platforms such as Taobao, Tmall, JD.com, or Pinduoduo, the text does not indicate support, so local e-commerce data tools should be considered. Network access and payment availability from mainland China are not confirmed in the text; payment is only described as credit card via Stripe, so practical verification is needed.
