Ecommerce Image SEO Checker

Page markers, explainable image SEO scoring, page audits, fix suggestions, and local XMP export.

ImgSEO is a Chrome extension that checks image SEO on ecommerce product pages while you browse. Click the SEO marker on any product image to open a Side Panel with a 0-100 score, a plain-language explanation of what is holding the image back, and the fixes to apply. Run a page audit to see every image at once, then copy ready-to-use alt text and metadata or export optimized files. It is built for the daily reality of ecommerce image work: dozens of product images per page, a CMS that is slow to update, and no easy way to tell which image is actually the problem. WHY IT HELPS Product images are often the least reviewed part of a listing. Missing alt text, camera filenames like IMG_4821.jpg, no caption, oversized files, and missing structured data affect accessibility and page experience, but they stay invisible until someone checks them one by one. ImgSEO puts that check directly on the page. WHAT YOU GET - On-page markers: every eligible product image gets a small SEO score label. Click it to open the report in Chrome's Side Panel. - Clear scoring: a 0-100 score with a level (Good, Needs Work, Poor) and a plain-language breakdown of the signals behind it. - Page audit: scan the current page, see the average score, the problem distribution, and each image's issues in one list. - Ready-to-use fixes: alt text, SEO title, description, filename, keywords, caption, and a JSON-LD snippet, with character limits for Amazon, Shopify, Etsy, and generic ecommerce. - Export: resize and re-encode images, write XMP metadata, or batch the whole audit into a ZIP with an optional CSV. - Optional AI assist: draft copy and visual attributes with Chrome's built-in on-device model. No API key, no account. - Four languages: English, Japanese, Simplified Chinese, and Traditional Chinese. The first run follows your Chrome UI language and remembers your last choice. PRIVACY Everything runs locally. Images are fetched only to read metadata, sample pixels, or produce an exported copy. Nothing is uploaded, there is no account, and no analytics are collected. GETTING STARTED 1. Install ImgSEO. 2. Open a product page on an enabled store domain. 3. Click the SEO marker on an image, or open the Side Panel to audit the page. Defaults cover Amazon, Taobao, Tmall, Shopee, and AliExpress. Add or remove domains in Options. Chrome 116 or newer is required. NOTES The score is ImgSEO's own heuristic for prioritization, not a Google ranking factor. Audit scores are page-level estimates until a full report is opened. Platform limits follow published platform guidance. No extension can guarantee rankings or rich results.
