A major goal of website operation is keeping readers engaged for as long as possible. The longer a visitor spends browsing your site, the more likely they are to return again and again to absorb information, shop, or enjoy the many other useful features of your site. Keeping readers engaged also has a positive effect on your site’s SEO, or search engine optimization.

Google uses countless metrics to analyze your site’s success. It assesses page views, your site’s bounce rate, and the amount of time a user spends on your site. It’s easy to understand that you need users to stay on your site longer, but the task of accomplishing that goal can be a bit more difficult. Internal linking strategies can help.

I spent years trying to improve my site’s reader engagement, and it wasn’t until I developed a solid internal linking strategy that I began to see improvements. I also found that the best way of achieving a successful internal linking strategy was not by doing it all on my own. WordPress offers a variety of internal linking plugins to make creating internal links as easy as possible. A few seconds and a few clicks, and your post is optimized with links to existing content on your site.

The following guide provides more information about internal linking while directing you to the top internal linking plugins I’ve found and put to use. Weigh the pros and cons and choose the internal linking plugin that works best for you and your website.

What Do Internal Linking Plugins Do?

In short, and internal linking plugin is an WordPress plugin that allows you to interlink articles, tags, and blog posts more quickly and easily. You simply chose keywords or key phrases and choose a URL to link with that keyword or key phrase. Internal linking plugins allow you to determine whether you want a link to be nofollow or do-follow.

Internal linking plugins help you link to older articles that may seem lost in the archives of your website. It can make these articles visible to readers again, allowing them find useful information related to a certain topic more easily. A larger number of links to pages deep in your site can improve your overall SEO rankings, and ultimately, improve website traffic. Using a quality internal linking plugin is a no-brainer. You just need to choose one that works best for you and your website.

What to Look For

Most webmasters look for a few key concepts when choosing an internal linking plugin. Ease of use is one of those concepts. The easier the plugin makes creating your internal links, the more likely you are to use it, and the more likely you are to develop a solid internal linking strategy. One key feature that makes an internal linking plugin easier to use is its ability to automatically suggest URLs for you. This means you no longer have to browse throughout your site’s entire history to find URLs related to your current topic.

It’s also important to choose a plugin that offers internal linking analysis and reporting. Analysis and reporting will help you understand how successful your link building strategy is, so you can make changes when needed. Look for the following features in an internal linking plugin, and you’ll be off to a good start.

  • Ease of use
  • Automatic linking suggestions
  • Analysis and reporting

What to Avoid

Now that you know what to look for in a solid internal linking plugin, it’s important to know what to avoid as well. The experts at Thrive Agency recommend being cautious of over-optimizing anchor text. It’s important to vary your target keywords, but over-optimizing them can actually harm your site’s ratings. They also recommend being aware of when your link building plugin is digging too deep into your site. It is suggested that internal links do not lead more than three clicks deep into your site. Your internal linking plugin may automatically reach beyond three clicks, so you’ll either need to monitor your plugin or choose a new one.

It’s important that your internal linking plugin provides a moderate number of internal links per page — not too many or too few. Viewers who see an abundance of internal links on a given page will consider the article, or even the entire website, spammy. Be sure your internal linking strategy only includes links leading to sites that are useful for your readers. In short, the following are a few features of link building plugins to avoid.

  • Over-optimization of anchor text
  • Linking too deep within the site
  • Too many internal links per page

1. Link Whisper

My Pick
Link Whisper

When it comes to internal linking tools and plugins, nothing comes close to Link Whisper. I've tried many such tools and Link Whisper is hands-down the best whether you need to go back and build piles of internal links among existing content or create internal links to and from new content on the fly. You can customize the hyperlink text as well which is huge or go with the suggested text and create links with a click of a box.

I’ve used it to build dozens of internal links for existing content as well as creating links to and from new content on the fly.

Webmasters consistently praise Link Whisper as the most advanced internal linking plugin available. What makes this plugin so special is its ability to scan all of your site’s pages in seconds and immediately make internal link suggestions. Link Whisper uses artificial intelligence to suggest the most relevant internal links and keywords as you write the article. The user simply checks boxes, clicks ‘save,’ and moves onto the next task.

Even more, Link Whisper provides useful reporting, showing the user how many internal and external links lead to or from each post. Link Whisper is not a free plugin, but most users claim the amount of time they save while using the plugin and increased Google rankings are worth the price.

It then suggests other posts from across your site that would be most ideal for internal linking. The “Link Suggestions” tab can be found on the right side of the page when using this plugin.

Simply start typing @, and the auto-complete function will place the correct link associated with that keyword.  This makes the plugin easy to use, and it makes locating preferred content easier for viewers too. The main function of the Mentionable plugin is to link keywords to internal posts, and the plugin makes adjusting link settings easy.

Many experts suggest using WordPress’ own tools to create internal links.
