Scan your eBay listings in bulk with this mobile-responsiveness checker:

The quickest way to determine whether your listings are mobile-ready and will fit on handheld devices is to bulk scan them here. Spending a little time with an autoscan will allow you to locate worst-case listings and tackle them first.


This scan is informational only and will produce color-coded size results. The tool will scan items found publicly on eBay without accessing your account, and can not search out-of-stock items or adult items, since those items are not publicly viewable. This tool will advise how well your listings will shrink for mobile devices. A different tool, the ActiveContentEditor, will assist in bulk modifying listings.

This tool can scan up to 10,000 items (approx 100 to 500 items per minute, depending on the size of your description code and images embedded within the description). Use the search criteria to reduce the search range if you have more than 10,000 items, thus creating subgroupings based on category, price, or date order.

Alternatively, you can retrieve adult, out-of-stock, and more than 10K items through File Exchange and can load that data into this tool when choosing the File Exchange option from the country dropdown list.

Limitations: This scanner is best suited to desktop browsers and will not likely produce accurate results if run from a mobile device. The tool will load each listing into your browser for sizing (up to 25 listings at a time), so if you have an underpowered system or a handheld device, you may not want to use this tool.

Accuracy: Listings that can reflow down to 320 pixels wide are considered mobile friendly. The results produced by this scanner are "ballpark" because eBay displays the description without a doctype so that each browser will render in quirks mode in a different manner. Because the scan and measurement are performed within your browser, you may see slightly different results if run from a different browser. This tool is best suited to locating those listings that are far from mobile-friendly.

If your page contains Active Content, that content will be part of the measurement and may result in a less accurate reading if the Active content either widens or narrows the screen. It is best to remove Active Content before using this scanner.


Overlaps If scanning while listings are being added or removed, the results may have overlaps or gaps in data returned from eBay, as the tool will be retrieving from a moving target. The overlaps are captured here to adjust the totals, and you can ignore them. The gaps can only be captured by a subsequent scan at a later time.

Untested This tool will build a list of up to 10,000 active items. All untested item rows will remain purple. Any that remain purple after the scan has completed have encountered a scan problem. Try scanning those items individually in the ActiveContentSandbox tool. If the scan stalls on a page, click the next page number to skip the problem and continue the scan.

Shrinks to 320 pixels When an item reflows and flexes for mobile viewing on the smallest device (320 pixels), its row will turn white and you can add the Viewport meta tag to those listings.

Shrinks to 360 pixels If an item is close, but not quite small enough for mobile viewing, the row will turn yellow. In this case, when the page will reflow no smaller, it may be adequate to do nothing and allow the page to be shrunken by the mobile device.

Shrinks to 480 An item that will flex down to 480 may need only minimal code repair to make the page work.

Larger than 480 If a page will not flex smaller than 480 pixels wide, the row will turn red. It is recommended that you rework the page code. You can edit code in the Sandbox tool to experiment with sizes and sizing issues. ActiveContentSandbox tool.

Custom For advanced users. If a Custom Capture phrase is entered, items returned by eBay's search will be further examined for that phrase (useful for detecting content within HTML or script). Any item containing that custom phrase will be added to a summary list, and will not affect the other filters or row displays.   details

After the items have been returned by eBay's standard search filters, this tool will additionally scan those descriptions for your custom search phrase. This can be useful for grouping your updates by type of template or hosting service.

A single line of plain text or code will be found exactly as formatted, and will be case insensitive. Be wary of choosing text that might have embedded formatting tags, or else include the tags as part of your text, for example:
  We do not accept returns
  We do <strong>not</strong> accept returns
This tool will also support Regex (Regular Expression) wildcards for locating larger blocks or multiple configurations. The regex must be grouped within parentheses, and be further bounded by slashes "/", with a trailing (optional) "i" designator for "ignore case". This specific configuration will tell this tool that you have a regex. Regex examples are:
  /(returns (are )?not (accepted|allowed))/i
Since Regex filters can be tricky to create, it is wise to load a single listing and tweak your regex with one item before starting a scan of hundreds or thousands of items, only to discover the filter was inadequate or malformed.

No Custom Additionally, if a custom phrase is entered, any item that does not contain that phrase will be added to the No-Custom list, but will not be marked in the grid.

A,B,C,D,E,F,G,H columns: Some page elements may affect mobile sizing (for better or worse). These columns provide a count of those elements, which may be useful to advanced users. ( A = Viewport, B = Media Queries, C = Img "max-width", D = Images, E = Linked Stylesheets, F = Tables, G = Pre tags, H = Text runs )

The button will appear on individual rows. The button will open that item in the ActiveContentSandbox where you can experiment with code changes to further improve the mobile flexibility of your template.

The button will open the item in eBay's listing editor, where eBay's "Description Checker" tool will allow you to fix listings one at a time. If a small number of rows are highlighted in color, and images in your description are the likely reason the description won't flex small enough, you may want to allow eBay to fix those items for you. However, eBay's mobile-friendly checker has limited capabilities and that tool's suggestions for repair may not actually improve the mobile friendliness of your listing, since the only feature that tool can affect is the resizing of photos. If you have tables, non-breaking words, non-breaking underlines, or hard-coded dimensions in your listings, more effort may be required and you may want to make bulk changes within eBay's "Bulk Edit and Replace" tool or within the "Bulk Active Content Editor".
