Six best WordPress SEO plugins in 2021

Now that we’ve discussed why you should use an SEO plugin, let’s look at six excellent alternatives. The one that’s the best fit for you will depend the depth of features you need, but they all offer a budget-friendly way to implement your SEO strategy.

1. Yoast SEO

Yoast SEO is one of the most popular WordPress SEO plugins, and it’s easy to see why. It comes packed with excellent features out of the box to help you produce search-engine-friendly content that is easy to read.

For instance, Yoast SEO adds a meta box to all your pages and posts, which enables you to easily set your focus keyword, meta description, canonical URLs, and more. Also, its readability analysis will help you optimize your posts with practical suggestions for copy improvement.

Other features include:

  • Advanced XML sitemaps
  • Schema markup
  • Breadcrumbs control
  • Support for ‘noindex’ content
  • Title and meta description templates

2. All In One SEO Pack

The All in One SEO Pack plugin is an excellent alternative to Yoast. With it, beginners won’t have to worry about complex settings as it works well immediately upon activation. For example, it automatically generates meta tags and optimizes your titles for Google and other search engines.

That said, advanced users will be able to customize their experience and override automatic features.

This plugin enables you to automatically generate a sitemap so that crawlers can easily assess your site. Also, you can save your settings and re-apply them each time you publish new content.

It also gives you more control/flexibility than the built-in XML sitemap feature that WordPress added to the core in WordPress 5.5.

Pricing: Free.

Squirrly SEO is a beginner-friendly SEO tool that generates recommendations in real-time. It enables you to optimize content for your chosen keyword as you’re writing your content. Also, it provides a competitor analysis with suggestions of what you can improve to outrank similar pages.

Besides that, Squirrly SEO comes with innovative features to help with your marketing efforts. For instance, it measures your audience engagement and offers actionable advice to improve your click-through rates (CTRs). Plus, it will transfer all your pre-existing settings if you switch from another SEO plugin.

Other features include:

  • Schema markup
  • Free coaching sessions
  • ‘Noindex’ options

The plugin is fully integrated with Google Analytics, enabling you to track your SEO efforts. Additionally, its content analysis tool will provide optimization tips to help you write better posts. Developers will be able to apply additional hooks to customize the plugin fully as well.

Rank Math is also integrated with Google Search Console and keyword ranking tools, which is useful if you want to stay ahead of your competitors. Besides that, its built-in 404 monitor helps you resolve errors for a better user experience.
