The 5 Best Free SEO WordPress Plugins in 2021
3.5 billion Google searches are made every day.
That’s roughly 40,000 search queries every second.
With the volume of Google searches growing by roughly 10% every year, any website not optimised for search engines are not only losing a huge amount of traffic, but also potential customers.
It’s clear that any website that doesn’t already follow SEO best practices will be left behind.
Fortunately, there are thousands of useful tools available online that can point you the right direction. There’s never been a better time to conduct a full website audit and revisit your activated WordPress Plugins.
Here are 5 of the best free SEO WordPress plugins available to kickstart your website’s SEO.
- Improved site speed and performance through caching
- Content delivery network (CDN) integration
W3 Total Cache is one of the most popular free SEO WordPress plugins for a reason.
Once installed, it will greatly improve your site speed and user experience by storing and delivering cached pages to your users.
The question is, what exactly is caching?
Imagine if a teacher asked their class to solve 3,189,400 divided by 15,947?
This equation isn’t easy to solve and would require both time and effort to answer. Eventually, a student would correctly answer 200. If the teacher was to then ask the exact same question again, everyone would now be able to answer instantly. This is because the initial time-consuming process had already been completed and the answer was now readily available.
With W3 Total Cache enabled, any webpage that a user has previously visited can now be delivered super-fast as the heavy lifting has already been done.
A faster site not only improves SEO performance but also enhances the overall user experience. With page speed being a huge factor in bounce rate, W3 Total Cache’s free SEO WordPress Plugin very might well be the difference between an unsure visitor converting into a paying customer.

Furthermore, RankMath has features for internal linking recommendations, 404 monitoring, XML sitemaps, redirect management, local SEO, rich snippets, and image SEO.
To put it simply, if you want to save time and get results, look no further than the one-stop-shop tool that is the free SEO WordPress plugin, RankMath.
- Image compression and optimisation
- Lazy loading
- Incorrect image size detection tool
Website speed is one of the most important SEO ranking factors. One of the best ways to improve page speed is by reducing the overall page size. It’s pretty straightforward – the smaller the page, the faster it loads.
Smush Image Compression and Optimisation is an amazing free SEO WordPress plugin that will reduce the size of your images so your pages can be served quicker.
However, what sets Smush apart is their lossless compression. Many image compression tools will inadvertently warp image quality when reducing size. Smush strips any unnecessary data and reduces file size without affecting the appearance of the image.
The Smush free SEO WordPress plugin also features a lazy loader and an incorrect image size detection tool. If your page has many images below the fold (they require scrolling further down the page to view), lazy loading will significantly boost your page speed.
It does this by displaying only the images being currently viewed and delaying others further down the page. The incorrect image size detection tool identifies any images that are abnormally large in size so you can quickly stop these images slowing down your site.
- Cleans and reduces database size, improving website performance
- Scheduled maintenance and cleaning
Your entire website is stored in your WordPress database.
All of your pages, posts, comments, tags, categories, users, custom fields, and revisions – they’re all kept there. Over time, you’ll also end up also storing a lot of unnecessary data. That’s where the free SEO WordPress plugin WP-Optimize clears out everything bloating your database by cleaning up your MySQL tables.
Now, this might seem like a lot of technical jargon, so why is any of this important?
MySQL is the database management system WordPress uses. Each section, feature and functionality has a table in the database. Over time, a lot of rarely-used data is added your database tables, making them unnecessarily large and slow to access. Requesting MySQL to optimise its tables will keep your site running quickly.
The best thing about this free SEO WordPress plugin is that it can do this all automatically based on a schedule which you set. Whether you want to clean once a week, or once a month, this can be set up with a few simple clicks. Once enabled, WP-Optimize will make sure that your website is regularly maintained and at peak performance.
- Enables Accelerated Mobile Pages (AMP)
- Prebuilt AMP themes and designs
AMP for WP is a clever, free SEO WordPress plugin which adds Accelerated Mobile Pages (Google AMP Project) functionality to your WordPress site. In a world where half of all browsed website are done using a mobile, it has become more important than ever that websites optimised for mobile devices.
AMP is essentially a stripped-down, bare-bones version of your site’s mobile pages. It removes a lot of elements that take a toll on your site’s speed and performance. The logic behind AMP is that a faster load time will lead to better engagement and reduced bounce rate, resulting in an improved mobile ranking.
By streamlining and speeding up mobile use, AMP has the potential to make your visitors happy, which means a lot to Google. If Google is happy with your website, then it’s more likely you’ll get higher rankings, bring in more traffic, and increase conversions.
