ImageSEO is the AI plugin that writes SEO-optimized alt text, filenames, and captions for your entire WordPress media library. Built for Google, ChatGPT, Claude, and Perplexity. Works with every theme. Free to install.
Four silent leaks every WordPress site has. None of them show in your dashboard.
Which means WordPress sets the SEO baseline for almost half the internet. That baseline is „empty alt text by default.”
Upload 1,000 images. Zero alt text filled in. WP’s default behavior is silence. Your media library is a ranking wasteland.
Google Images + Google Lens is now the #1 traffic source for product pages, blog posts, and photography sites. You’re invisible to all of it without alt text.
ChatGPT, Claude and Perplexity cite pages with proper alt text 4× more often. Your images decide whether AI search mentions you.
Six features. One plugin. Zero manual work.
Written by models trained specifically on image-to-text and SEO intent. Not generic captioners. Not keyword stuffing. Natural language that Google, ChatGPT and screen readers all love.
Your IMG_4273.jpg becomes red-leather-handbag-boutique.jpg. Google Lens uses filenames as ranking signals. Automatic rewriting, no broken links, no lost attachments.
Install the plugin, hit „scan”, walk away. Thousands of existing images get rewritten in the background. No CSV exports, no downtime.
English, French, German, Spanish, Italian, Portuguese, Dutch — and more. Alt text generated natively in your site’s language. Polylang and WPML compatible.
Every alt text we write passes real accessibility audits. Good for screen readers, good for compliance, good for conversion. Same text, three wins.
Better Facebook, Twitter, LinkedIn cards. Auto-generated social previews for every post. More clicks from shared links.
ImageSEO writes to the WordPress media library directly. If your theme or page builder reads from WP media (all of them do), we’re compatible. Tested on every major stack.

Yes. The WordPress plugin is free to install. Your first 10 images are on us. If you have more than 10 images (you do), upgrade to a paid plan: Starter is €4.99/mo, Standard €11.99/mo, Premium €24.99/mo. See all plans.
No. ImageSEO only writes to the alt, title, caption, and filename fields. Your actual image files are untouched. If we rewrite a filename, we preserve the old URL via a WordPress redirect — no broken links, no lost attachments, no SEO damage.
Yes. Alt text is generated natively in the post’s language, not translated. If you have a post in French, we write the alt text in French. Same for German, Spanish, Italian, Portuguese, and more.
Yes. That’s the default use case. Click „scan media library” and ImageSEO rewrites every image with missing alt text. Throttled to never slow your site. Can handle 10,000+ image libraries.
Self-hosted (wordpress.org): yes, always. WordPress.com: only on Business and eCommerce plans where plugins are allowed.
ImageSEO only touches images with empty or missing alt text by default. You can opt in to overwrite everything, or exclude specific media IDs.
No. Optimization runs as a WordPress cron job, throttled and batched. You can pause, resume, or schedule it for off-hours. Zero frontend impact.
Google re-crawls your sitemap within days. We’ve seen Google Images traffic increase on client sites within 7–14 days of first run. AI search citations take 2–4 weeks to show up.
Kostenlos starten. 10 images on us. No credit card required. Install the plugin, sign in, optimize.
