Do You Need SEO Plugins for WordPress?

Search Engine Optimisation (SEO) can be overwhelming, especially for business owners transitioning online and setting up their websites. This is where SEO plugins come to your aid. Using a good SEO plugin can make ranking in organic search much simpler, whilst helping you obtain good-quality traffic.

SEO plugins are not essential, especially if you’re familiar with SEO best practices already. You can achieve the same results without the use of plugins if you already have the know-how. However, if you’re a beginner, SEO plugins are a fantastic aid to help you improve your website.

WordPress already takes care of most of the technical SEO aspects straight out of the box. You can simply focus on the design, content or any on-page aspects and anything behind closed doors is already optimised.

SEO Plugins on the other hand are designed to guide you in creating better content so that it is more search engine and user-friendly. Remember, SEO plugins offer guidance, they cannot guarantee ranking success. It is down to you to carry out all of the optimisation.

What Do SEO Plugins Do?

SEO plugins can help you with a variety of tasks. These include:

  • Writing titles and meta descriptions
  • Creating XML sitemaps
  • Creating a robots.txt file
  • Optimising content for keywords
  • Improving content readability
  • Auditing your website
  • Applying schema markup

When used effectively, SEO plugins can give you the arsenal you need to boost your organic traffic and improve your SERP rankings.

Without further ado, let’s get started with the best free-to-use WordPress Plugins of 2023.

The Best WordPress SEO Plugins for 2023

1. All In One SEO (AIOSEO)

AIOSEO was created by Michael Torbert and Steve Mortiboy in 2007. It has since become a widely used SEO plugin, with over 2 million active installations. It was acquired by Syed Balkhi in 2020 with a simple goal: to make SEO easy for beginners. AIOSEO is considered to be one of the best WordPress SEO plugins.

Considered to be one of the main rivals of Yoast SEO, this plugin is packed with useful features such as keyword optimisation, title optimisation, and a readability score for your content. The plugin also takes care of XML sitemaps and meta tags generation. Additionally, the plugin provides an overall site score with a rating out of 100, making it easier for users to visualise their website’s quality.

If you do decide to opt into the paid plan, you can get started for as little as $49 a year for 1 website, which is ideal for those on a budget. In fact, we use the pro package here at Comprehension Digital to take advantage of the extra features such as internal link assistant and schema markup. However, if these features aren’t necessary for you the free plugin still packs a punch.

Features of All In One SEO (AIOSEO)

  • Automatically generates XML sitemaps to help search engines crawl and index the website.
  • Real-time content analysis and suggestions, such as checking keyword density and readability, to help optimise content for search engines.

With Yoast SEO, you can easily optimise your pages and posts for specific keywords, and the plugin provides helpful feedback on how to improve your content to make it more search-engine friendly.

One of the best things about Yoast SEO is that it’s easy to use. The plugin provides clear feedback on how to improve your content, and it’s designed to be accessible to people who aren’t SEO experts. That said, if you are an SEO expert, Yoast SEO provides plenty of advanced settings and features that allow you to fine-tune your website’s optimisation.

Yoast SEO is also highly customisable. You can choose which features you want to use, and you can adjust settings to fit your specific needs. The plugin is also regularly updated, which means it stays up-to-date with changes to search engine algorithms and best practices.

The premium version of the plugin costs $89 a year for a single site which despite not being the cheapest, you can trust that Yoast SEO will help you achieve your SEO goals effectively. Likewise, with AIOSEO, the paid version is not essential if the features won’t benefit you.

Rank Math’s free version offers more features than AIOSEO and Yoast. Link suggestions and local SEO are among the features that are not available in the free versions of AIOSEO and Yoast. If these are features you want to use in particular then Rank Math can be an excellent free to use option.

One of the unique features of this plugin is its Google Search Console integration. You can access information such as the number of impressions your content is getting and how your keywords are performing. This can all be accessed from your WordPress dashboard.

Rank Math is a cost-effective option. At only $59 a year for unlimited websites, this is absolutely amazing value for money if you want to take advantage of their premium features.

SEOPress is packed with useful features such as XML sitemaps creation, content analysis and title and meta description optimisation. It’s a simple-to-use, beginner-friendly plugin that anyone can use. Furthermore, you can keep track of how their visitors are interacting with their site through seamless integration with Google Analytics.

One of the most noteworthy aspects of this plugin is that it has no advertising, footprints, or white label, both in the backend and frontend.

SEOPress is one of the cheapest on the market. The premium version costs only $49 a year, and that is for unlimited websites. By purchasing a premium subscription you can take advantage of features such as OpenAI integration. This lets you generate titles and meta descriptions based on the content of your page, ultimately saving you a lot of time and inspiration.

A lot of the SEO plugins mentioned in this article come with an overwhelming amount of settings. This isn’t a bad thing, some users prefer this. But for a complete beginner who doesn’t want to understand complex terms, Slim SEO is a good option as the configuration of this plugin is done automatically.

Features of this plugin include the ability to automatically generate meta tags, sitemaps, breadcrumbs, schema and redirections. However, Slim SEO does lack the on-page optimisation features that other plugins offer. Unless you’re already comfortable writing search engine-friendly content, this plugin may not be right for you.

For only $39 per year, you can obtain a personal license for Slim SEO that covers a single website. In addition, by purchasing this paid package, you can gain access to more advanced schema features, including custom schema, additional schema types, and schema builder.

Alternatively, you can choose to purchase the lifetime package, which costs only $129 and is valid forever. This is beneficial for saving money in the long run if you decide to stick with Slim SEO.

Features of Slim SEO

  • Creates an XML sitemap to help search engines crawl and index websites more efficiently.
  • Allows you to customise the title, description, and other meta tags for each page and post on your website to make them more appealing to search engines.

Despite the plugin being preconfigured, you can naturally tweak it however you like.

The SEO Framework is completely free to use, which means that you can take advantage of all critical SEO features without having to spend a penny. What I appreciate about The SEO Framework is that they don’t try and sell you anything extra. Both beginners and experts can start using it right out of the box with a wide range of features at their disposal.

Moreover, if your website starts generating revenue, you may want to consider upgrading to one of their paid packages. This will provide you with extra extensions, including content spam protection and Google Analytics integration.

The pro package can be purchased for $84 per year. However, if you find that these extensions are not useful to you, there is no need to worry. The SEO Framework has more than enough to offer in its free version.

Summary

SEO can be confusing, especially if you don’t have the right tools at your disposal. In this article, we have discussed the best SEO plugins for WordPress that are free to use. It’s important you weigh up the features of each, and find one that is the best fit for your goals.
