With APT you won't have to manually add tags ever again. You just have to create a list of tags with related words for each of them and you are done. This plugin will add relevant tags automatically when a post is published or updated. It is perfect for autoblogs and lazy bloggers. :)

Features

• Automatically adds tags to posts according to their title, content and excerpt
• Tags are added to a post also when different user-defined keywords are found (example: tag "cat" is added if you assign to it words "cats, kitty, meow" and they are found in a post by the plugin)
• Smart wildcard representation of any alphanumeric characters for related words (pattern "cat*" will match "cats" and "category", pattern "c*t" will match "cat" and "colt" etc.)
• Configurable maximum number of tags per post (APT won't add more tags than you want)
• Bulk tagging of already existing posts
• Workaround for Latin diacritic characters (non-Latin alphabets like Arabic or Chinese aren't supported)
• Supports importing already existing tags, creating and importing backups
