How to Develop a WordPress Content Optimization Plugin

Step 1: Set Up the Plugin Structure

Create a new folder in the /wp-content/plugins/ directory. Inside this folder, create a main PHP file (my-content-optimizer.php) and add the plugin header:

<?php
/**
 * Plugin Name: My Content Optimizer
 * Description: A custom WordPress content optimization plugin.
 * Version: 1.0
 * Author: Your Name
 * License: GPL2
 */

Step 2: Implement Content Analysis Functions

For example, a function to analyze post readability using Flesch Reading Ease:

function analyze_readability($content) {
    $words = str_word_count($content);
    $sentences = preg_match_all('/[.!?]/', $content);
    $syllables = preg_match_all('/[aeiouy]+/i', $content);

    $score = 206.835 - (1.015 * ($words / $sentences)) - (84.6 * ($syllables / $words));
    return $score;
}

Step 3: Add Meta Tag Optimization Features

To automate meta title and description generation:

function generate_meta_description($content) {
    $excerpt = substr(strip_tags($content), 0, 160);
    return $excerpt . '...';
}

Step 4: Implement Image Optimization

Automatically compress images on upload:

function compress_image($file) {
    $quality = 80;
    $image = imagecreatefromjpeg($file);
    imagejpeg($image, $file, $quality);
}
add_filter('wp_handle_upload', 'compress_image');

Step 5: Integrate AI Content Suggestions (Optional)

Use an API like OpenAI to suggest improvements:

function suggest_improvements($content) {
    $api_url = 'https://api.example.com/suggestions';
    $response = wp_remote_post($api_url, [
        'body' => json_encode(['content' => $content]),
        'headers' => ['Content-Type' => 'application/json']
    ]);
    return wp_remote_retrieve_body($response);
}

Step 6: Optimize for Speed

To minify HTML output:

function minify_html($buffer) {
    return preg_replace(['/[\n\r]/', '/\s+/'], ['', ' '], $buffer);
}
ob_start('minify_html');

Step 7: Publish Your Plugin

After testing, submit your plugin to the WordPress Plugin Repository to reach a wider audience.
