ZIK Analytics Chrome Extension
The ZIK Analytics Chrome extension is listed on the Chrome Web Store as "eBay Sold History Button - See Item Purchase History".
The ZIK Analytics Chrome extension is listed on the Chrome Web Store as "eBay Sold History Button - See Item Purchase History". It adds research tools to eBay item pages: a HISTORY button next to the listing title (shortcut Alt+Z, or Option+Z on Mac), a research bar, and sidebars for sold history and competitor details. Users can save products and add sellers to a watchlist, which syncs with a ZIK Analytics account. The extension is free to install, but detailed numbers such as sales velocity, price distribution and variation performance need a paid ZIK plan. The publisher is N.G.C.A. Technology Enterprises Ltd, the company behind ZIK Analytics. In September 2026 the listing showed version 2.9, updated August 3, 2026, with about 50,000 users and a 4.1 rating from 27 reviews.

FAQ
Open the Chrome Web Store and find "eBay Sold History Button - See Item Purchase History", published by zikanalytics.com, then click Add to Chrome. Next, open any eBay item page and a HISTORY button appears by the title. ZIK says installing is free with no credit card, and creating an account inside the extension also creates your ZIK Analytics account.
On an eBay item page, the extension adds a research bar with the category, item location, delivery details and number of watchers. The HISTORY button, also opened with Alt+Z or Option+Z on Mac, opens a sold history sidebar with the item's sales report. A competitor sidebar shows the seller's feedback score and listings. You can save products and add sellers to a watchlist.
You can install and use it for free, but the free version is limited. Free users get the research bar, can open the sold history and competitor sidebars, and can save products and sellers. The actual numbers, such as 7, 14 and 30-day sales counts, price distribution, seller revenue, sell-through rate and variation breakdowns, need a paid ZIK plan, which starts with a $1 trial.
The extension is published by N.G.C.A. Technology Enterprises Ltd, the company behind ZIK Analytics, and has about 50,000 users. Its Chrome Web Store privacy section says data is not sold to third parties or used beyond the extension's core function. Version 2.9 asks only for Chrome's storage permission, runs on eBay item and purchase history pages, and also includes a script set to load on all websites.
Not all. Version 2.9 is set to run on item pages of eBay.com, eBay.co.uk, eBay.de, eBay.fr, eBay.it, eBay.es, eBay.ca, eBay.com.au, eBay.at, eBay.be, eBay.ch, eBay.ie, eBay.nl, eBay.pl, eBay.in, eBay.com.hk, eBay.com.my, eBay.com.sg and eBay.ph. It only activates on item pages and purchase history pages, not on search results. The ZIK web app's own research covers 10 eBay countries.
ZIK has no public troubleshooting article for this, but common causes are easy to check. The extension only works on eBay item pages whose address contains /itm/ on a supported eBay site. The free version shows the layout without detailed numbers, so log in and check that your plan or trial is active. Items with no sales have no sold history. Reload the page, update the extension, or contact ZIK chat support.
No. ZIK Booster is a separate Chrome extension. Its Chrome Web Store listing describes it as a helper extension that fetches metadata about eBay users, and third-party listings describe features such as a VeRO checker, competition checker and seller location. The main ZIK research extension is "eBay Sold History Button", which adds the HISTORY button and research sidebars to eBay item pages.
To remove the extension, open chrome://extensions, find "eBay Sold History Button" and click Remove, or right-click its icon and choose Remove from Chrome. Removing it does not stop billing. To cancel a paid plan, log in to ZIK Analytics, open the Management panel, click Billing and then Cancel. If you are on the $1 trial, cancel within 7 days to avoid a charge.
