The plugin is simple, yet its purpose can always be noticed in website management. You will probably run into dead links as your blog and content grow. 

You need a plugin to help automate this inevitable sad event in blogging. Redirection WordPress plugin is one of the free SEO plugins for WordPress blogs that you will always find handy for this task.

7. WP-Optimize

WP-Optimize - WordPress database cleanup plugin

WP Optimize is a valuable plugin that cleans and optimizes your WordPress database. It aids in improving website performance by removing unnecessary data and enhancing database efficiency.

One thing I like about this plugin is that it focuses on one task and is the best for handling it. 

The primary function of WP-Optimize is to clean and optimize your WordPress database and tables. 

Though it has other notable functions like cache, image optimization, and file minification, they are secondary and unnecessary. You don’t need to activate them if you have another plugin like WP Rocket, which is far superior in handling those other tasks. 

In fact, many SEOs recommend turning off the WP Rocket database optimization module for WP-Optimize. Doing this might give you a more optimized site performance.

What Are The Best Free SEO Plugins For a WordPress Site?

Many SEO plugins are excellent free candidates for WordPress sites. However, the most popular options are Yoast, All-in-one SEO, Rank Math, and SEOpress. 

These plugins offer many helpful and advanced features to help you optimize your site for more search engine visibility. Some of the plugin’s features include keyword research capability, AI content audit and optimization, title and meta description management, image SEO, XML site map generator, etc. 

How do I Choose The Right SEO Plugin for my website?

First, you need to have clarity on your website features and needs. The more clarity you have, the better you can determine what plugin can serve your purpose. 

Also, consider your experience level, technical ability, and how competent you can handle complex setups and information. Some plugins require advanced users, while others suit beginners and anyone. The best way to learn which plugin is right for you is to test different similar plugins. The more you try, the better you understand the function and features of each plugin. 

Are Free SEO Plugins as good as Premium Plugins?

Yes, free SEO plugins are as good as their premium version. However, plugin features are the main advantage of having a paid plugin. Paid plugins offer more features than the free or lite version. You don’t need to buy a premium plugin version if you’re not interested in the pro features. So, ensure you go through the plugin features – pro vs free – before deciding.
