How do you get a higher rank for content created in WordPress? By creating quality content that is highly sought after. However, using the best plugins for search engine optimization will also play a role in success.

Today, the importance of SEO for businesses is even more monumental.

Below are 27 of the best free WordPress SEO plugins I can find to help get your content kick-started on the search engines. After all, what’s the purpose of having a website if no one visits?

1. Google XML Sitemaps

Google XML Sitemaps

The first part to marketing a website and getting the attention of search engines is the sitemap. Google XML Sitemaps is a free plugin that is active on more than one million installations of WordPress.

A sitemap tells search engines where to look for content. This plugin will automatically create it for you. All you need to do is activate the plugin and modify which of your posts and pages to list in the file.

Making sure content is indexed in Google is important as one in every six people uses it throughout the year.

2. Yoast SEO

Yoast SEO

Yoast SEO is an excellent plugin to have for many reasons. It can help you write content by analyzing what you create in real time and give you suggestions about how to fix it.

Yoast installs an addition to the text editor in WordPress. It will analyze the material in real time for readability and keyword use. This way, you’ll create better content for both search engines and visitors alike.

3. W3 Total Cache

W3 Total Cache

Website speed plays an important role in SEO. Thanks to W3 Total Cache, the site has potential to be faster than it was in the past. Between leverage caching on browsers and storing copies of the site itself locally, this free plugin is exceptionally useful.

In some instances, W3 Total Cache improves overall performance by as much as 10 times. However, this depends on many factors and may be different in each case. It also works with CDNs such as using CloudFlare.

4. Broken Link Checker

Broken Link Checker

If links are broken on the website, Google and Bing may rank the pages poorly. Broken Link Checker makes sure all of those links are still good.

Instead of going to each post and page to test the links, this plugin does it automatically for you.

Broken Link Checker installs an admin panel in the WordPress dashboard. From this section, you can quickly alter the link itself without sifting through many posts and pages to find it.

5. WPSSO Schema JSON-LD Markup

WPSSO Schema

Google uses the JSON-LD markup for displaying pages and posts in its search results. You may have seen this when looking at content that has star ratings and other snippets of information. WPSSO Schema JSON-LD Markup implements this feature into WordPress to help sites get more exposure from this platform.

Things like recipes, lists, user reviews and more are available when a post or page shows up in results.

6. All in One SEO Pack

All In One SEO

The All in One SEO Pack is an incredibly popular plugin to enhance optimization. It’s one of the longest running and most popular plugins for SEO. It supports a range of tools from security to automatic meta tag creation.

If you’re an advanced user, you can take advantage of fine-tuning the plugin for even greater control. Personally, I like this plugin’s ability to integrate with eCommerce platforms such as WooCommerce. According to the developer, it’s the only free plugin that does.

7. Google Analytics

Google Analytics

Google Analytics is one of those tools that every website owner needs to use. It will help with content development while giving insight into traffic behavior. The Google Analytics plugin allows you to see those results directly from the WordPress admin dashboard.

It’s a simple system that only requires the “UA” number Google provides for tracking the site. After which, the site admin can see a range of tracking data without leaving the dashboard.

8. Landing Page

Landing Page

Landing Page is a great tool for those who sell goods or services. It comes with a drag-and-drop builder, visual editor, additional widgets and a slew of other additions to help score well with SEO.

One of the things that stands out most is the integration with platforms like WooCommerce as well as some of the best email marketing services on the Internet.

9. SEO Optimized Images

SEO Image Optimizer

From social media to website posts, graphics can make all the difference in attracting an audience. However, a lot of developers don’t use the “ALT” tag when it comes to SEO. In SEO Image Optimizer, this tag automatically becomes an addition.

The SEO Optimized Images plugin is useful for several reasons. It will dynamically insert the tags for images, but it will also optimize the image itself such as using compression. This improves site speed to boost SEO.

10. Title Experiments Free

Title Experiments Free

A lot of people will visit your website based on the title they see in search engines. Title Experiments Free gives you a tool that will help you fine-tune the opening of your content.

Users can determine which title is used for search engines from the settings of the plugin. Outside of the search engines, this plugin will display variations of the title to visitors you create and record which one performs better.

A lot of WordPress installations will come pre-loaded with Jetpack. This plugin has several modules that add far more functionality to WordPress. For instance, Site Verification helps an individual verify he or she owns the domain with Search Console in Google, Pinterest, Bing and Yandex.

Photon is Jetpack’s image optimization module, which automatically adjusts them for different screen resolutions. Images are placed on a CDN for even faster distribution.

And sitemaps can also be quickly set up through Jetpack.

This plugin has more than 20 modules that are accessible simply by switching them on in Jetpack’s settings. From optimization to content development, it’s one of the more useful plugins I’ve come across.

12. Starbox


The content of the post isn’t the only thing that has potential for optimization. Adding a bit of flare to the author box is useful as well, and Starbox is an excellent plugin for this purpose.

Author bios made with Starbox include specific social media links, different themes for layout, bio images and more. Starbox may also be a great choice for showing guest posts.

13. Yet Another Related Posts Plugin


Yet Another Related Posts Plugin, or YARPP, is a common plugin that shows posts that are related at the end of an article. Using algorithms to find content on your site, YARPP will display material that is relevant much like how Google searches for linking content.

ShortPixel is an exceptionally popular plugin for compressing JPG, PNG, GIF and even PDF files to use on your website. It also affects images that are stored in other plugins like the NextGEN Gallery.

Rich Contact Widget not only gives visitors a way to contact you, but it also includes the micro data for improving local search results.

Search engines often base indexing a site on how active it is. The more posts that are published regularly, the more often Google and Bing crawl for content. An Editorial Calendar can help keep writers motivated and plan out when posts are created.
