11 Best SEO Plugins for WordPress

Would you like to rank higher on Google? Then using an SEO plugin may be one of the best solutions. SEO stands for “Search Engine Optimization” and is key to get traffic from organic (therefore, free) search results. It aims to improve your site’s position on Google’s first page by focusing on your site content, structure,and technical audits. You don’t need to install dozens of SEO plugins to make your site stand out, but a few can be very helpful. In this article, we are sharing 11 popular SEO tools you can use to improve your ranking. 

Why You Need an SEO Plugin for Your WordPress Website

SEO plugins are handy in telling you what changes you need to make to your content and how to optimize your WordPress pages or posts for search engines. For instance, they crawl your website and flag technical issues that can harm your ranking. They can also offer suggestions for on-page optimization, readability, topics you should cover, how long your content should be, and how you compare with your competitors. 

All the most popular SEO plugins allow you (at least) to add SEO titles, meta descriptions, and identify the primary keyword to create relevant content according to users’ needs and help your site rank better and get more traffic. 

How Performance Affects SEO 

Page speed is a direct ranking factor for Google’s algorithm. When measuring the performance of your site, Lighthouse also takes into consideration the score of your three Core Web Vitals, which mainly stand for page loading time (with the Largest Contentful Paint), interactivity (with the First Input Delay), and visual stability (with the Cumulative Layout Shift).

Any efforts towards improving those Core Web Vitals will be appreciated by Google who will be more likely to rank your WordPress site better.

How The User Experience Affects SEO

Although user experience doesn’t directly affect organic ranking, it indirectly affects other ranking factors, such as slow page speed or lack of optimization on mobile. By maintaining a great speed, you are more likely to have visitors read more pages of your sites and stay on them longer. Google’s research showed that the chance of a bounce increased by 32% when a page load time went from 1 to 3 seconds and by 123 % when the page load time went from 1 to 10 seconds! 

Checking Your Current SEO State

You can run a test in PageSpeed Insights and check if your page passes the basic SEO optimization features. That should give you some useful tips on where to start your optimization journey.

While PageSpeed is excellent for measuring performance and giving advanced technical recommendations, the SEO report remains pretty basic. That’s exactly why a WordPress plugin can be useful: tracking the quality of your site content through text readability and relevancy.
