How to choose a WordPress SEO plugin?

As you can see, there are many plugins with similar functionality on the list, and each has its pros and cons. Most likely, there is no single ideal solution, but downloading, let alone buying each one to understand which one is best for you, is also not an option.

To decide at the start, it is important to analyze all the options you like in advance. What to look for:

SEO Plugin features

Everything is clear here: before starting work, you need to understand what problem you need to solve and whether the selected plugin can do it.

Compatibility with third-party plugins

Before choosing an SEO plugin, make sure that it supports integration with your other work tools if needed.


Of course, the price of a plugin is often dictated by the wealth of its options, but again, you may not need all of them, and you will not be able to pay a lot.

The number of users

If we are talking about a plugin from the WordPress directory, then everything is simple, this number shows off on the main page. The more users trust a plugin, the better it rather is. Also, pay attention to the number of reviews. If there are millions of downloads and few reviews, this is suspicious. If the plugin is not in the directory, it is still easy to determine the approximate number of users by checking the statistics of page visits in SimilarWeb, and also by looking at reviews on various resources.


Always study reviews in the directory, and services such as G2 Crowd, TrustPilot, and others.


An important point that many do not think about. It is important that the plugin is updated frequently and is up to date with the latest version of WordPress, this minimizes the chance that the plugin may be harmful to your site.

User support

Most of the premium plugins offer good personalized support, the free ones are most often supported through reviews in the directory and forums. Pay attention to how quickly developers respond to user requests, this is important
