10 Best WordPress SEO plugins

Digital marketing

When WordPress website developers start working on a new project, they ask their customers what plugins they plan to connect. Beginners ask: “Why? Is CMS basic functionality is not enough?”

WordPress SEO plugins are specialized extensions that automatize the management of the website functionality. Such a plugin can be developed not only by a specialist but by any user.

Due to the fact that SEO plugins for WordPress are very many, of course, some questions may arise:

  • Why are my SEO Yoast plugins in WordPress disappearing?
  • How many SEO plugins do I need for WordPress?
  • Which WordPress plugins hurt SEO?
  • How hard is it to change SEO plugins on WordPress?
  • Which WordPress plugins might interfere with SEO?

I will answer these and other questions in this article to make choosing the right WordPress SEO plugin easier.

Physically, a plugin looks like a script added either in controlling files or mounted into the website header or footer. When the resource is loaded, the script sends a command for certain performing functions to the system.

The difference is that the user would have to write or make the required on the website without the WordPress SEO plugin. The WordPress SEO plugin automatizes the routines, thus saving time and resources both for owners and specialists.

What are WordPress SEO plugins

WordPress has about 16,000 different plugins that simplify the work with resources developed with this CMS type. About 1000 of them are responsible for different functions in the sphere of SEO.

Proper SEO of a Web resource fills texts with keywords, adds meta tags, generates friendly URLs, structure optimization, and configuration of inner interlinking. Specialists and website owners have about 200 Google ranking factors for SEO.

Plugins allow optimizing all parameters for optimization. This makes the work of a SE specialist faster. Besides that, most plugins have automatic hints. So even if you are not a specialist, you can set up the website for search engines and even lead it to the top results. If the specialist sets up the website manually, he will spend much more time.

Types of WordPress SEO plugins

SEO plugins in the CMS library are divided into several groups. They will be represented in the material below.

Universal SEO plugins

Such giants represent the best WordPress SEO plugins as Yoast, All-in-one-Pack, SEO Framework. These are the most popular and full-scale plugins that allow making full SEO optimization.

Their universality determines their popularity. They can be used for optimizing a blog, online store, or multilingual portal. But their universality is their drawback. It is worth using universal plugins on a large website only where their functionality would be fully applied. WordPress plugins are rather heavy and slow down the website load if used on a small website (please note that the plugin adds its script that requires processing).

Data cache

This group of plugins partially solves the problem with a load of pages and data on the website. The plugins compress and optimize CSS and JS scripts. In addition, they are integrated with technical server add-ins for speeding up the website load when the user opens it in the browser.

Content analysis

The group works with the text itself. These WordPress plugins help content managers who work on text readability.

WordPress SEO Plugins working with text calculate the readability index. Some of them check the content for plagiarism. More powerful plugins can select keywords for publication. The publication specialist can add them into meta tags or insert the anchor links to the page, ALT, or TITLE SEO tags for images.

Some plugins can analyze the word frequency in the text. This function will help the content editor check to what extent the publication corresponds with the page topic.

Image optimization

A separate media optimization plays an important role in accelerating the website load. Compression of images and video allows saving the space on the hosting.

Image and video lazy load plugins are worth attention. These plugins allow the user not to wait for a load of visual content if s/he wishes to read the text on the Web page. Instead, while s/he is reading, the plugin gradually loads the images and videos showing the load indicator or divides them into pixels, loading the preview.

Universal WordPress SEO plugins

Caching in WordPress

A cache is a temporary storage of data that has been used recently. When a user visits a resource again, they are loaded from this temporary storage. This accelerates the work with the website. However, a lot of static content on the website does not change, so you spend time and traffic if you load it again. Caching plugins in WordPress save static data.
