Kraan Media SEO & AI Meta Filler

by marcelkraan

Description

Kraan Media SEO & AI Meta Filler is a WordPress plugin designed to bulk-process your media library. It helps to ensure images on your website are optimized by automatically generating Alt-texts, Titles, and Captions.

You can choose between two generation methods:

Parse from Filename (Local): Cleans up your current filenames (e.g., red-mercedes-c180.jpg becomes “Red Mercedes C180”) and applies them to your SEO meta tags.
AI Vision API (Remote): Utilizes the external OpenAI API (gpt-4o-mini Vision model) to analyze images and write descriptive Alt-texts.

Features

Automated Background Cronjob: Enable the hourly cron to process up to 50 new media uploads in the background.
Fallback System: If the OpenAI API fails, hits a rate limit, or rejects an image, the plugin falls back to the local ‘Parse from Filename’ method to prevent the bulk process from stopping.
Bulk Dashboard: An AJAX-powered dashboard with live ETA, processing speed metrics, and a dynamic progress bar.
Overwrite Mode: Optionally force the plugin to overwrite existing media tags in your library.

External Services

This plugin can connect to an external API (OpenAI) to generate alternative text for images when the “AI Vision API” method is enabled in the settings.

Service Used: OpenAI API (https://platform.openai.com)
Purpose: To analyze image content via the gpt-4o-mini Vision model and return a short, descriptive string of text in Dutch to be used as an Alt tag.
Data Transmitted: When the AI method is active, the plugin sends a direct URL of the image thumbnail (or the full image URL if no thumbnail exists) alongside a static text prompt to the OpenAI API servers. This process only occurs when explicitly initiated by the user.
Terms of Use: OpenAI Terms of Use
Privacy Policy: OpenAI Privacy Policy

Activate the plugin through the ‘Plugins’ menu in WordPress.
Navigate to Settings > Kraan Media SEO (or via the Media menu).
Select your preferred Generation Method.

Click Start to begin the bulk optimization.

Faq

I am getting an “insufficient_quota” or “Billing” error from OpenAI. What do I do?

OpenAI’s API is a prepaid service and is not included in a ChatGPT Plus subscription. You must add a minimum balance to your OpenAI developer account at platform.openai.com/settings/organization/billing/overview.

Will the AI reject certain images?

Yes. OpenAI has a safety filter and may reject certain content. If this happens, the plugin will catch the error, bypass the AI, and safely fall back to the filename-parsing method for that specific image. Your bulk process will continue.

Does the Cronjob slow down my website?

No. The automatic cronjob is limited to processing a maximum of 50 empty images per hour in the background.
