This article won’t try to list every WordPress SEO plugin.

Instead, we’ll share the most powerful plugins that can help you optimize your WordPress website for SEO and get more traffic from search engines like Google.

Some plugins are free. Some aren’t. But they’re all useful.

Let’s start.

1. Semrush SEO Writing Assistant

Semrush’s SEO Writing Assistant plugin helps you write content optimized for both users and search engines.

It scores your content based on readability, tone, originality, and SEO. And offers advice to improve these aspects.

For example, if the plugin spots that your article’s title doesn’t include your target keyword—the search query you want to rank for in Google—it will highlight that as an issue and recommend adding it to your title.

Or, if the plugin detects duplicate or plagiarized content, it will highlight the problem text.

2. Yoast SEO

Yoast SEO is one of the most powerful SEO plugins for WordPress.

Yoast SEO plugin

At its most basic level, Yoast allows you to set the title tag, URL slug, and meta description on your pages. Which are all important aspects of a strong SEO strategy.

Plus, Yoast can help you manage other technical tasks like:

  • Setting up canonical URLs on your pages
  • Setting up meta robots tags, such as noarchive, nosnippet, or noimageindex
  • Providing titles for your pages’ breadcrumbs
  • Preventing search engines from indexing your pages
  • Preventing search engines from following links on your pages
Yoast SEO lets you manage technical tasks

When it comes to content-level optimization, Yoast identifies SEO-related issues in your content. And highlights opportunities for improvements.

Note that these are just recommendations. And you don’t always have to follow every Yoast recommendation. 

For example, Yoast suggests evenly distributing your focus keyword throughout the content. This is an outdated SEO tactic.

We don’t recommend paying attention to this, as it won’t help you rank. In fact, it can even have the opposite effect in some cases.

Besides scanning your content for SEO-related issues, Yoast also analyzes your content’s readability. And provides suggestions for improvements. Such as:

  • Using active voice
  • Short sentences and paragraphs
  • Simple word choices

SEOPress plugin

As with Yoast, SEOPress allows you to set up title tags and meta descriptions on your pages. 

It will also show you if the title or meta description is too long. To avoid your descriptions being cut off in search results.

Plus, SEOPress lets you define Open Graph tags. These tags control how your preview links appear on social media platforms such as Facebook, Twitter, LinkedIn, etc.

People are more likely to share content with optimized Open Graph tags, as they make content more eye-catching in social media feeds.

For example, here’s how a preview link without Open Graph tags appears for our blog post about title tags.

example of a preview link without Open Graph tags

It uses the first image from the blog post as the preview image. And the title and descriptions aren’t optimized.

A preview link with Open Graph tags, on the other hand, appears how you want it to:

SEOPress also has a feature that shows how well optimized your page is for your target keyword(s).

If your bullets are green, you’re likely in the clear.

But don’t overthink if that’s not the case.
