Do I need an API key to use Alt Audit?

No! You can start using Alt Audit immediately without an API key. The core bulk rule-based alt text generation works completely offline and is 100% free. You only need an API key from altaudit.com if you want to use the optional AI-powered generation (which analyzes actual image content using computer vision). New users get 25 free credits to try the AI features.

What's the difference between Free and AI generation?

Free Rule-based generation (NO API NEEDED):

Works instantly offline on your server.
Uses smart templates with 9 variables (site name, page title, product title, image filename, etc.).
Context-aware patterns that adapt based on content type (homepage, posts, WooCommerce products).
100% free and unlimited. Perfect for large image libraries and quick SEO wins. Optional AI-powered generation (REQUIRES API):

Can I use this for bulk alt text generation?

Yes! Alt Audit includes powerful bulk processing tools completely for free. You can scan your entire media library at once, identify missing alt attributes, and generate text for hundreds of images simultaneously using our free rule-based engine.

Will this improve my image SEO?

Absolutely! Properly written alt text is one of the most important factors for Image SEO. It helps search engines index your images, improves visibility in Google Image Search, and enhances overall page relevance.

Does this connect to third-party services?

Only if you choose to use the AI features. The free rule-based generation does NOT connect to any external services and works completely offline on your server. The optional AI-powered feature connects securely to the Alt Audit API (https://altaudit.com/api/v1) to analyze images. This is strictly optional and transparent.

Can I generate alt text in my language?

Yes! If you use the optional AI-powered generation, Alt Audit supports 130+ languages. Simply select your preferred language in Settings, and all AI-generated alt text will be written natively in that language (including Spanish, French, German, Russian, Chinese, Arabic, and more). Perfect for European Accessibility Act (EAA) compliance and multilingual websites.

Does this plugin make my website 100% accessible?

No single plugin can guarantee 100% accessibility. Alt Audit is a powerful tool specifically focused on WCAG 2.1 Level A Success Criterion 1.1.1 (Non-text Content). It makes finding and fixing image accessibility issues significantly easier and faster.

What WCAG standards does this plugin check?

Alt Audit focuses on WCAG 2.1 Level A compliance for images. It checks for:

Missing alt text (critical barrier)
Empty alt text for decorative images
Weak or insufficient descriptions
Length compliance (under 125 characters)

Does this work with Gutenberg and page builders?

Yes! Alt Audit integrates seamlessly with the Gutenberg Block Editor (real-time quality checking), the Classic Editor, and the standard WordPress Media Library.

Is the quality assessment automatic?

Yes! Alt Audit scans and assesses all your images into 5 statuses:

Missing (Critical - fails WCAG)
Decorative (Appropriate for decorative images)
Weak (Needs improvement)
Good (Acceptable)
Excellent (Optimal)

Can I manually edit the generated alt text?

Yes, you have full control. You can review, edit, or reject any generated alt text before saving it to your media library.

How is pricing structured for AI generation?

Remember, rule-based generation is always 100% free and unlimited. If you choose to use AI, we use a simple pay-as-you-go model:

Get 25 free credits on signup (1 credit = 1 image analyzed).
Purchase credit packages only when needed. No monthly subscriptions!
Special white-label plans are available for SEO agencies.

Do you offer plans for SEO agencies?

Yes! We have Agency Plans with discounted pricing, white-label options to rebrand the plugin, and centralized management for multiple client sites. Contact us at altaudit.com/contact.

Will this slow down my website?

No! Alt Audit is built for performance. Scanning happens only in the admin dashboard, and no front-end scripts are loaded for your visitors. It will not impact your page load times.
