ARI SEO Content Checker

By OlehDankevych · 2025-02-26 · Updated 2025-03-04

Overview

I started this project when I spoke with several SEO specialists. They told me they had trouble finding a tool that could analyze website content in a clear and detailed way. They needed something simple and free to help improve their SEO. This conversation inspired me to create my own plugin.

I began by working on a tool that could examine posts and give data about keywords and text quality. I wanted the plugin to show the main keyword in each post and also find related words. Later, I added more features like TF-IDF analysis, topic modeling, and readability analysis. I also built in functions for sentiment analysis, named entity recognition (NER), and word embeddings. All these tools help to understand and improve the content for search engines.

A very important feature I added was stopword filtering and normalization. I noticed that common words like "the", "and", "or" could confuse the analysis. So, I developed a special filtering page where these stopwords are removed from the text. This makes the analysis much more accurate.

During testing, many SEO specialists tried the plugin for free. They were very happy with the results and told me that such a tool was missing in the market. Their positive feedback encouraged me to continue improving the plugin.

Technical Requirements

• WordPress Version: Compatible with WordPress 5.0 or later.

• PHP Version: Requires PHP 7.0 or higher.

• Database: MySQL 5.6 or later / MariaDB equivalent.

• JavaScript: Uses jQuery; assets are enqueued only on plugin-related admin pages.

This is the very first version of the plugin. I plan to update it regularly with more features and improvements. I recommend subscribing to my blog so you can stay informed about new updates and enhancements.
