Getting Started with our WordPress Plugin

In short: install the free Image SEO plugin from Plugins → Add New (search for “imageseo”), activate it, then click ImageSEO in the admin menu. On the Welcome tab, create a free account or paste your API key. From then on, new uploads get alt text and a descriptive file name automatically, and the Bulk optimization tab handles the images you already have. It takes about five minutes.

Step 1: Install and activate the plugin

1. In your WordPress dashboard, go to Plugins → Add New.
2. Search for imageseo. The plugin is called “Image SEO – AI-Driven Image SEO Optimizer”.
3. Click Install Now, then Activate.

You can also download it from its WordPress.org page and upload the ZIP under Plugins → Add New → Upload Plugin.

Step 2: Connect your account

Click ImageSEO in the admin menu. The Welcome tab gives you two options:

• New to ImageSEO: choose I want to register for a free account, enter your name, email and a password, and click Create account. Your API key is filled in for you.
• Already have an account: paste your key into the API Key field. Here’s where to find your API key.

When you see “API key validated”, the plugin is connected. The free plan includes 10 images a month.

Step 3: Check the settings

Open the Settings tab. Under On-upload optimization you decide what happens to every new image:

• Fill alt and Rename files are switched on by default, so each upload gets alt text and a descriptive file name.
• Optimize title and Optimize caption add a title and caption as well.
• Language sets the language of everything ImageSEO writes. It starts on your site’s language.

The same tab also has the Social media card generator, which creates preview images for links shared on Facebook, LinkedIn and X. See social media preview cards.

Step 4: Optimize the images you already have

Open the Bulk optimization tab, choose which images to include and whether to rewrite all alt texts or only fill missing ones, then click Start optimization. It runs in the background. The full walkthrough is in how to bulk optimize your images.

Step 5: Check that everything works

The Health tab runs a quick check: connection to ImageSEO, API key, credits remaining, plugin version and background tasks (WP-Cron). Each line shows its current status, so you can see at a glance what needs fixing. You can also open the Media Library in list view and look at the Alt (imageseo) and Filename (imageseo) columns, where you can edit or re-optimize single images. See how to rename image files in WordPress.

ImageSEO is listed as compatible with major SEO, caching and compression plugins; see plugin and theme compatibility. Questions? Email support@imageseo.io.
