原文外掛簡介
Erdo Image Optimizer is not just another image compression plugin. It is a complete Image SEO & Performance Suite that covers WebP/AVIF conversion, bulk alt text management, filename sanitization, lazy loading, unused media cleanup, and a 6-point SEO audit — all in a single, modern dashboard.
Most image optimization plugins stop at compression. Erdo goes further: every image in your media library receives a professional SEO health score (0 out of 6). You will know exactly which images are hurting your Google rankings and how to fix them, in bulk, in minutes.
Why Erdo Image Optimizer?
Image SEO Audit (6 Points): Every image gets a score from 0 to 6 based on alt text, filename quality, title, contextual relevance, dimensions, and format. Fix failing criteria with one click — no guesswork.
WebP & AVIF Converter: One-click conversion from JPEG, PNG, GIF, and HEIC/HEIF to WebP or AVIF. Smart Quality mode automatically finds the smallest file size that still looks great.
Bulk Alt Text Generation: Automatically generate descriptive alt text from filenames for every image missing it. Fix hundreds of images in seconds — critical for accessibility and image SEO.
Filename Sanitizer: Transforms messy uploads like IMG_1234 (copy).JPG into SEO-friendly professional-web-design.webp at upload time. Bulk-rename existing images with automatic database reference updates.
Unused Media Cleanup: Scans your entire library to find images that appear nowhere on your site. Free up disk space and stop confusing search crawlers with orphaned files.
Lazy Loading & WebP Serving: Inject loading="lazy" into content images automatically. Serve WebP to compatible browsers via .htaccess rewrite (Apache) or PHP
Background Queue & WP-CLI: Bulk-convert thousands of images via WP-Cron — close the browser tab and let it run. Full CLI support: wp erdo convert, audit, restore, stats, clean-cache.
BunnyCDN & REST API: Upload converted images directly to BunnyCDN storage. Headless access via /wp-json/erdo/v1/stats and /wp-json/erdo/v1/audit REST endpoints.
