ImageSEO writes alt text, captions and descriptive filenames for every image on your WordPress site, in several languages and in bulk

Every WordPress site has a media library full of IMG_4273.jpg with an empty alt field. Everyone knows it hurts accessibility and image search, and nobody wants to spend a weekend writing descriptions for 3,000 product shots. ImageSEO is built for that exact guilt. Install the plugin, connect an account, and it writes alt text, titles, captions and cleaner filenames for new uploads or for the whole backlog.

The pitch has grown with the times. The site now talks about visibility in AI search tools and Google Lens as well as Google Images, and it adds Open Graph tags for nicer social previews. The underlying value has not changed though: decent descriptive alt text, at scale, in several languages. For a WooCommerce shop with a large catalogue, that alone can justify a paid plan.

Where it shines

Big catalogues are its happy place. A WooCommerce shop with thousands of product shots can clear the whole backlog in one bulk run, and every new upload gets alt text, a title, a caption and a descriptive filename on the way in. It slots into the tools those sites already use, from the block editor to Elementor, Divi and WPBakery, so nobody has to change how they build pages.

Shops selling across borders get the extra treat of alt text written natively in English, French, German, Spanish, Italian, Portuguese, Dutch and more. The best way to start is the free allowance of 10 images a month: run it on a few product pages, read what it wrote, then move to a monthly plan or a top-up pack, which never expires, for the full library. Paid plans come with a 14-day money-back guarantee.

The chore every WordPress site puts off, handed to a plugin that does it in bulk and in your customers' language.
