AltText AI Review: Automate Image SEO in Minutes

Your images could be driving thousands of visitors. But without proper alt text, they are basically invisible to search engines.

The tool I use to fix this is AltText AI, available as a lifetime deal on AppSumo. Instead of paying a monthly subscription, you get a one-time purchase with monthly credits, and it connects directly to WordPress, Shopify, WooCommerce, and more.

The problem most site owners ignore#

Over 50% of websites are missing alt text entirely. The other half is mostly writing generic descriptions that do nothing for search rankings. Both groups are leaving free traffic on the table.

Here's the math on doing it manually: 100 images, roughly 3 to 4 hours of tedious work. And that's assuming you're even optimizing for the right keywords, which most people aren't. The result is that alt text becomes the SEO task that always gets pushed to next week.

Proper image alt text can increase click-through rates by up to 70%. That's not a minor optimization, that's a meaningful traffic lever most sites have never touched. If you want to find the right keywords to target in your alt text, the free SEO Keyword Generator GPT is a good starting point before you run any bulk generation.

How AltText AI actually works#

At its simplest, you upload an image, click generate, and get an accurate description back in seconds. Upload a diagram of a flowchart and it doesn't just say "chart", it describes the content, pulls out abbreviations, and reads the actual labels. That's the baseline.

The more useful features are the ones that scale.

Scrape page. Paste a URL and AltText AI pulls every image from that page. From there, you enter a target keyword, say, "stock appreciation rights", select all images, and click generate. Seven images processed in under a few seconds, each with alt text that naturally includes your keyword. What would have taken an hour of manual work is done before you finish your coffee.

WordPress plugin with SEO plugin integration. Install the AltText AI plugin, connect your API key, and every image you upload to your media library gets alt text generated automatically on upload. No extra steps. But the smarter part: it reads your focus keyword from Yoast or RankMath and works that keyword into the alt text, even if the image isn't directly related to the topic. Upload a mountain flower photo to a post targeting "hiking trails" and the generated alt text will tie the image back to that keyword naturally. For posts where you're using illustrative images that aren't literal representations of your keyword, this matters.

Bulk backlog generation. This is the one that saves the most time for existing sites. In my own library, I had 143 images, 57 with no alt text at all. I selected those 57, clicked generate, and the entire backlog was cleared in under a minute. You can also add a target keyword or negative keywords to exclude terms you don't want appearing. Once it runs, you can skip images already processed by AltText AI so you're not overwriting anything you've already optimized manually.

Who needs this#

If you run a content site with more than a handful of posts, the backlog feature alone justifies the tool. If you run an e-commerce store uploading product images regularly, the WordPress or Shopify integration means you never have to think about alt text again, it just happens on upload.

The developer API also connects to n8n and other automation tools, so if you're building AI agents or automated content pipelines, you can wire alt text generation directly into your workflow without touching the dashboard.

The AppSumo lifetime deal means you're not committing to another monthly subscription. You pay once, get a monthly credit allocation, and the tool runs in the background doing work that most of your competitors are skipping entirely. That's about as low-friction a SEO win as you'll find.
