WordPress is a simple-to-use content management system that’s also free. It offers everyone from solo bloggers to the world’s leading brands a platform to create custom and powerful websites. No wonder almost a third of all websites run on WP!

Still, WordPress was made for users, not for Google or SEOs. That’s why SEO plugins exist — to plug in the holes with added functionality that helps your content be indexed by search engines and found by searchers.

As a marketer, content creator or analyst, how do you choose the best SEO plugin for your sites? Here, we’ll take a look at six plugins, their many features, and finally a price comparison chart so that you can compare them:

1. Yoast SEO
2. All-In-One SEO Pack
3. SEO Ultimate
4. SEO Squirrly
5. SEOPressor Connect
6. Bruce Clay SEO WP (our own)

Plugins often come in both free and premium versions; the premium versions unlock more functionality and service. I’ll address both versions where appropriate.

Plugin No. 6 is our soon-to-be-launched WP plugin, Bruce Clay SEO, which fills in the gaps left by other plugins on this list (see our list of what your SEO plugin is missing).

1. Yoast SEO

Yoast SEO is the most popular SEO plugin. It’s easy to use, driven by a simple user interface. The majority of people use the free version.

Here’s what the free version offers (from its plugin page):

• Bulk editor to make large-scale edits to a site

Strengths: As a leading plugin, it’s driven by market awareness and brand presence. It’s easy to use. The free version is typically enough for most users.
Weaknesses: It’s built for everyone and no one industry in particular. As a result, some users feel the SEO recommendations are too generic. In addition, even though it’s fairly simple to use, the features may seem overwhelming to beginners.

SEOPressor Connect is the most advanced of these SEO plugins, in my opinion.

Weaknesses: Computes its own scores and tracks them over time, but lacks a connection to performance analytics data or search results. This means that the trends could be misleading since they don’t reflect how your content is actually performing in the search engines.
Active installs & ratings: The plugin does not appear in WordPress’s plugin directory, so this data is not available.

6. Bruce Clay SEO for WordPress (now in beta)

While many of the above plugins compete with each other, our approach is different. Bruce Clay SEO WP is meant to supplement and extend the free versions with powerful needed features.

We gathered input from industry practitioners on what they wanted to see in an SEO plugin. Then we designed our plugin not to replace the plugins you may be using, but to provide much more data than is available today.

Of course, our plugin provides capabilities similar to others as well, but that is just in case you’re not using any other SEO plugins.

What makes this plugin unique: It enriches your publishing workspace with SEO insights based on real-time search results and analytics. In other words, you can see beyond the page you’re working on, without leaving WordPress. It’s the integration with our SEOToolSet and Google Search Console/Analytics that makes this possible.

The Bruce Clay SEO plugin works like software as a service (SaaS). Rather than a static one-size-fits-all checklist approach to optimizing a page or post, our plugin uses a live connection with the SEOToolSet software to analyze your keywords and competition in real time.

As a result, the optimization recommendations you see are customized. So your page can better compete in its specific ranking environment.

There’s no free version, but it’s priced affordably at $24.95/month per domain. (Try it! The first week is free — then you can decide if you want to keep it.)

As a bonus, plugin subscribers can also use the SEOToolSet itself. Data is shared between the plugin in WordPress and the user’s SEOToolSet account. Those who want to can run domain ranking reports and take advantage of many other external tools.

Bruce Clay SEO features are powered by patent-pending technology. WordPress users can:

• Optimize a page or post for more than one keyword.
• See clearly where keywords appear in the content through color coding.
• Know which pages and posts are your top performers.
• Identify problems with mobile usability and performance.
• Check the site for duplicate content.
• Evaluate top-ranked pages for your keywords in real-time.
• Get recommendations for keyword usage in tags and content (even word count) based upon competitors.
• Find out how much content has been written on your site per keyword.
• See how each of your pages or posts is performing, using integrated Google Analytics data.
• View top-performing posts or pages per author/contributor to the website as measured by visitors over a selectable period of time.
• Find out when there is a possibility of duplicate content, like meta information or the content on a page.
• Discover the page or post’s readability and compare it to keyword competitors.
• Use along with Yoast, if desired. Compatibility is built in.
