Transform Your Site with the 19 Best Free SEO Plugins for WordPress

WordPress is a very popular tool used to manage and organize website content. It controls more than 43% of all websites on the internet, which is more than any other CMS. To give you an idea, the biggest rival of WordPress only has a very small part of the market, around 2.6%.

While being popular comes with its benefits, it also has drawbacks. The WordPress plugin directory is akin to the Apple App Store. Just as iPhone users enjoy a plethora of app choices, WordPress users are inundated with options when it comes to plugins. With over 55,000 plugins currently available, navigating the directory can be overwhelming, especially if you’re new to WordPress.

Choosing the right SEO plugins for WordPress is crucial. It’s important to sift through the multitude of options and identify the gems. To aid you in this process, we’ve curated a list of the best free SEO plugins for WordPress. Implementing these on your website can significantly improve its chances of ranking higher in search engine results.

What Are SEO Plugins for WordPress?

WordPress SEO plugins are tools made for WordPress websites to make them better for search engines. They improve a website’s visibility in search engine results by focusing on both the technical and content-related parts of SEO. These plugins help users make meta tags, create site maps, manage redirects, and check how the website is doing overall. By using an SEO plugin, WordPress users can easily handle SEO and improve their chances of ranking well on search engines for their content.

SEO service providers often leverage WordPress plugins to streamline and enhance their clients’ SEO strategies. These plugins offer a convenient way to manage essential SEO tasks, ranging from keyword optimization to analytics tracking.

  1. a3 Lazy Load

a3 Lazy Load

The a3 Lazy Load WP Plugin is a tool that improves the performance of your WordPress website. It helps your website load faster by only loading images and videos when they are visible on the screen. This can improve your website’s SEO and overall user experience. It is a plugin that can be installed on your WordPress website to enhance its functionality.

If you are using WP Rocket, you can turn on lazy loading in the plugin settings. This will delay the loading of images and videos on your website. But if you don’t use WP Rocket, you can use this plugin to make lazy loading work on your website.

By default, when you install the plugin, it makes lazy loading work for all the pictures and videos on your website. However, if you want to choose specific images that will not be delayed in loading, you can adjust this in the plugin’s settings.



  1. Table of Contents Plus

Table of Contents Plus

If you regularly write long articles, it’s a good idea to divide them into smaller sections with links on the same page. Actually, this is what Google suggests. As per Google:

There are a few things you can do to increase the chances that they might appear on your pages. First, ensure that long, multi-topic pages on your site are well-structured and broken into distinct logical sections. Second, ensure that each section has an associated anchor with a descriptive name and that your page includes a “table of contents” which links to the individual anchors.

In order to easily add a table of contents to your website, you can use this free plugin. This plugin will create an index or table of contents specifically tailored to your long pages. By including a list of contents in your posts, you can help visitors easily find and go to specific sections within the posts.

This can also improve important SEO factors, such as the amount of time visitors spend on your site. Additionally, the plugin will also assist you in automatically capturing jump links in the search engine results page (SERP), which can further enhance your click-through rate (CTR).

For most WordPress sites, the free version of Autoptimize should be enough. If you have a big website, you can use Autoptimize Pro Services to easily set up Autoptimize on your site.

  1. Rel NoFollow

Rel NoFollow

Nofollow links may not have link juice, but most SEO experts agree that they are still valuable. By default, all links on WordPress are normal links that search engines follow unless stated otherwise. If you know HTML, you can add “nofollow” links in WordPress using the text editor.

But if you want to make things easier for yourself and be able to add “nofollow” links to your posts directly from the visual editor, you can use Rel Nofollow. This tool adds a checkbox called “nofollow” to the WordPress interface.



  1. Squirrly SEO

Squirrly SEO

Squirrly SEO is a good option instead of Yoast and All in One SEO Pack. It’s also better than lesser-known SEO plugins like Rank Math and SEOPress, which we previously talked about. Even though it is used by only 20,000 people on WordPress, it has support from important people in the industry like Brian Dean and Neil Patel. So, they must be doing something correctly.


The free version has basic optimization features, but if you want more advanced features, you have to switch to Squirrly Pro and pay for it.

  1. Bunny.net


Using a content delivery network (CDN) on your website can make it faster and better, which in turn can improve how well it shows up in search results. Not only that, but CDNs also make your site more secure. There are many companies that offer CDN services, but Bunny.net is a popular choice for people who use WordPress.

It is also very cheap because they use a payment system where you only pay for what you use, and your monthly bill could be as low as $1. Bunny.net’s WordPress plugin makes it simple for you to set up on your website. Once you’ve turned on this plugin, you just have to type in the name of your Pull Zone, and you’re ready to go.


It’s not free, but it’s one of the cheapest CDN providers available. As we said before, your monthly bill with Bunny.net could be as low as $1.

  1. MonsterInsights


You need to track analytics and performance to do SEO, and MonsterInsights helps you do that. It brings Google Analytics to your WordPress dashboard and gives you helpful tips on how to improve. You don’t need to use any code to install your Google Analytics tracking script.

Premium Pick for WordPress SEO Plugins

  1. WP Rocket

WP Rocket

Caching your webpages can make them load really fast and help improve your SEO and conversions. WordPress has many plugins that help cache websites. Some of these plugins are free, while others need to be paid for. We tested many free caching plugins from the WordPress plugin directory, but none of them helped our site’s performance as much as WP Rocket did.

Functionality-wise, WPRocket is the top caching plugin for WordPress available. This tool can greatly enhance how well your website works and make it load faster. Here are some things you can do with WP Rocket to make your website run better:

  • Make HTML and CSS files smaller

Besides these, you can connect your content delivery network (CDN) with WP Rocket to make your website faster and perform better.


WP Rocket doesn’t have a free version. One license of WP Rocket costs $49. The top free substitute for WP Rocket is WP Super Cache.

Final Thoughts

WordPress is undoubtedly a leading content management system for managing and optimizing content for search engines. The plugins listed above will certainly help you improve your Google rankings. However, securing a high position on search engines like Google or Bing requires more than just employing a few WordPress SEO plugins. It’s also crucial to focus on other key elements of SEO, such as keyword research, link building, and technical optimization of your website.


Do I need to have technical knowledge to use these plugins?

SEO plugins provide easy-to-follow instructions and helpful tools for analyzing content to help beginners with their SEO efforts. However, if you want to use advanced options, it can be helpful to have some understanding of SEO concepts.

Are SEO plugins enough to make my WordPress site rank well on search engines?

SEO plugins are helpful for improving website performance, but they are not the only thing needed for optimization. They help with the technical and on-page parts of SEO, but it is important to have a comprehensive approach to SEO for the best outcomes.

How can I pick the best SEO tool for my WordPress site?

Consider important aspects such as compatibility, user interface, reviews, and features. Trying out different plugins and making sure they are updated can help you make a better choice.

Are free SEO plugins effective compared to paid versions?

Free SEO plugins are effective for covering basic to intermediate SEO needs and are ideal for small to medium-sized websites. However, paid versions typically offer advanced features and premium support, making them better suited for larger sites or those with more complex SEO requirements.
