The fact is that as an online business, it’s hard to ignore the ease that WordPress brings to you; all thanks to the free and paid WordPress plugins available in the market.

As per a study by WPEngine, there are ~47,000 active WordPress plugins available and these have been collectively downloaded more than 600mn+ times.

And that brings in the problem of plenty i.e. making the right choice from so many options available.

Today, I am going to solve this problem for you by opening up my list of free SEO plugins for WordPress websites.

Here’s my list of 11 must-have and best free WordPress SEO plugins:-

1. Yoast SEO

Options: Free and Paid Plans

Store rating: 4.9 stars

Number of downloads: 5,000,000+

With five million-plus active installations to date, Yoast SEO is probably the most popular WordPress SEO plugin for checking on-page optimization.

When used with OnPage Champ’s SERP Audit functionality, Yoast SEO can save you lots of time and effort and give your on-page SEO a big boost.

I have been using Yoast for almost 4 years now and my SEO is incomplete without this plugin.

Use cases of Yoast

Yoast plugin covers multiple areas of SEO and makes your life very easy.

Here are some of the most used functionalities:-

a. Setting HTML tags

Using Yoast SEO plugin, you can set important HTML tags (like Title and Meta Description) for your web page.

While you enter the text, you can actually see the Google snippet and how your data gets rendered.

b. On-Page SEO sanity check

Just enter the content and Yoast plugin will indicate how well your content is optimized for the focus keyword.

This is just an indicative score and shouldn’t be considered sacrosanct.

That’s because Yoast plugin gives on-page SEO analysis based on the exact match keyword. However, Google may consider keyword variations and larger context of the keyword before deciding the ranks.

That’s why it makes sense to do SERP audit research via OnPage Champ and then refer/accept/reject the Yoast recommendations.

c. Readability analysis

This is an important feature of Yoast SEO.

It analyzes your page or post for ease of reading (known as readability).

This feature is helpful to understand whether your content is easy to read or not.

It analyses the sentence length, paragraph length, subheading distribution, use of transition words, etc.

d. Other use cases

Some other use cases of Yoast include:

  1. Auto generates XML sitemap (super helpful)
  2. Full control over breadcrumbs (an essential part of on-site SEO)
  3. Allows you to set canonical URLs (required for duplicate content)
  4. Setting of ‘nofollow’, ‘noindex’ attribute to pages
  5. Optimizing AMP pages (didn’t get a chance to use this feature)

Paid version

Paid plan of Yoast is available for USD 89 per website (one time). You can use the paid version to see on-page optimization for multiple keywords in a single view.

Store rating: 4/5

Number of downloads: 700,000+

Google hates broken links.

Not only do they break the user experience, but they also break the crawling of the Google bot and affect your SEO badly.

Therefore it becomes essential to ensure you replace all broken links with relevant working links.

Broken Link Checker analyzes your website for broken links – both internal as well as external.

It monitors and detects broken links across content, comments, blogs, etc.

As and when it finds any broken link, it reports the entire information to you (like the anchor text, the URL, HTTP status and the content page in which it is present).

You can unlink or edit the URL of that broken link from the plugin itself.

When you click edit URL, it provides you with suggestions for a replacement.

It is easy to use and you can fix broken links in bulk and with less time investment.

5. Redirection

Options: Free plan

Store rating: 4.5/5

Redirection is an important concept within SEO.

It’s because it directly impacts the user experience. And as we discussed earlier, anything that improves UX gets love from Google.

If you move an existing page to a new URL, it’s important you should use a 301 redirect to pass the SEO link juice.

If the page is temporarily down, you should do a 302 or a temporary redirect.

If the page has been deleted, there should be a 404 error along with a suitable redirect.

Redirection Plugin can help you implement 3XX and 4XX redirects and keep track of pages with 404 (not found error) errors.

Being more than 10 years old, it is one of the best redirect manager plugin available on WordPress to date.

Store Rating: 4.5/5

Number of downloads: 1,000,000+

Back in 2013, Google accepted that page speed is an important on-page SEO element and a critical ranking factor, especially for mobile devices.

The logic still remains the same: a fast loading website translates to a better user browsing experience and engagement.

Ask yourself a question: how long do you wait for a page to load? If it doesn’t load fast, what do you do?

You close the page and move to the next search result.

Thankfully, caching is one concept that can fire up the speed of your website and help you retain the traffic.

For those who are unfamiliar with the term, ‘caching” (pronounced “cashing”) is the process of storing data in a cache.

WP Last Modified Plugin helps you show the last modified/updated date on your web pages.

Again, both are critical SEO success factors.

Use cases of WP Last Modified

  1. It makes the user aware of the latest updates to the content. That improves the interaction with the user.
  2. The plugin automatically adds ‘dateModified’ schema markups in posts and pages that tell search engines like Google, Bing about the last modified date or time of posts and pages. It is beneficial because search engines may prefer refreshed or updated content for a particular query.
