Why sites WordPress lose image traffic

Four silent leaks every WordPress site has. None of them show in your dashboard.

43%

of the web runs WordPress

Which means WordPress sets the SEO baseline for almost half the internet. That baseline is « empty alt text by default. »

0

alt text WP writes for you

Upload 1,000 images. Zero alt text filled in. WP’s default behavior is silence. Your media library is a ranking wasteland.

20%

of Google search is images

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.

more citations with alt text

ChatGPT, Claude and Perplexity cite pages with proper alt text 4× more often. Your images decide whether AI search mentions you.

Everything ImageSEO does for your WordPress site

Six features. One plugin. Zero manual work.

✍️

AI alt text that ranks

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.

📁

Semantic filenames

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.

Bulk optimize the media library

Install the plugin, hit « scan », walk away. Thousands of existing images get rewritten in the background. No CSV exports, no downtime.

🌍

Native multilingual

English, French, German, Spanish, Italian, Portuguese, Dutch — and more. Alt text generated natively in your site’s language. Polylang and WPML compatible.

WCAG 2.1 accessibility

Every alt text we write passes real accessibility audits. Good for screen readers, good for compliance, good for conversion. Same text, three wins.

📸

Auto-updated Open Graph

Better Facebook, Twitter, LinkedIn cards. Auto-generated social previews for every post. More clicks from shared links.

Works with every WordPress theme

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.

Frequently asked WordPress questions

Is ImageSEO free for WordPress?

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.

Will it break my existing images?

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.

Does it work with Polylang / WPML?

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.

Can I run it on my existing media library (not just new uploads)?

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.

Does it work on self-hosted WordPress AND WordPress.com?

Self-hosted (wordpress.org): yes, always. WordPress.com: only on Business and eCommerce plans where plugins are allowed.

What if I already have alt text for some images?

ImageSEO only touches images with empty or missing alt text by default. You can opt in to overwrite everything, or exclude specific media IDs.

Will it make my site slower?

No. Optimization runs as a WordPress cron job, throttled and batched. You can pause, resume, or schedule it for off-hours. Zero frontend impact.

How fast will I see results in Google?

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.

Your WordPress site deserves better alt text.

Start free. 10 images on us. No credit card required. Install the plugin, sign in, optimize.
