Introducing Interlinking External Sites: Why Should You Need It?

We've just updated Slim SEO Link Manager which allows you to suggest links between external sites you own or manage. The good part is that when a site updates a post link, links in other sites will be auto-updated!

In this article, we'll walk you through this feature.

Why should you build links between sites in your network?

If you own multiple websites of the same niche, or in different niches, building links for them is a critical part of SEO. While you can get links from other websites, it's much easier to link from one website in your network to each other. This way, all the websites in your network receive links from other websites and thus increase the number of their backlinks.

Because you own this network, you can control what links are in and out, and which website should have more or less links. So, you can use links as an SEO signal to tell the search engines to promote the website(s) of the network you want.

Without a right tool to build backlinks, it's very hard to build and monitor them. Most people add links from sites to sites only once and then forget about them. They don't monitor them to see if the links are broken, or changed. And they can't count or see the effect of the links they build. It's pretty much based on their experience.

To solve this problem, since version 1.10, Slim SEO Link Manager add a new feature that allows you to build backlinks between sites in your network easily by suggesting and monitoring them automatically for you. Let's see how to do that!

Interlinking external sites in Slim SEO Link Manager

To start using this feature, please update the plugin to the latest version. Then go to Slim SEO > Link Manager > Settings:

Go to Slim SEO Link Manager settings tab

Scroll down and enable the Interlink external sites option:

Enable interlinking external sites option

The plugin will reveal two more options:

  • Secret key: this is the key used to connect with other sites securely. All the sites that are linked together must use the same key.
  • Linked sites: this is the list of the sites that are linked to from the current site.

Generating secret key

The next step is generating a secret key. To do that, click the Generate button. The plugin will create a key for you and fill in the input. After that, make sure you save the plugin settings by clicking the Save Changes button. Otherwise, the secret key is not saved yet.

This secret key is used to securely connect with your other sites, so keep it secret and don't share it anywhere. Otherwise, if hackers know this key (and your license key), they can connect to your website and get data.

Also note that this key must be the same on the sites that you want to connect. So after generating a key on one site, go to other sites and enter it in this setting. Then save the changes.

Adding sites

After having a secret key for all sites, then you need to connect them together. In the next option Linked sites, you'll see an input to enter the other sites' URLs. Make sure you enter the full URL of the site, including https://. After that click the Add site button.

The plugin will connect to the newly added site, using the secret key to verify the connection. When everything is finished, the new site will be shown in the table below.

List of linked sites

That's done the setup part for interlinking external sites. To see it in action, let's go to edit a post and see how the plugin suggests links from other sites.

Suggesting links from external sites

To build backlinks between sites, Slim SEO Link Manager will suggest links to other sites when you edit a post or a page. This way, you can link from your current post or page to a related or relevant post on other sites.

To do that, go to edit a post, and in the Link Manager meta box, below the post content, click the Link Suggestions and you'll see two new options: Internal and External tabs as follows:

View suggestions for links from external websites
  • Internal: it's the link suggestions within your site, e.g. the suggestions to link to posts and pages on your site. It's the functionality that has been in the plugin since the beginning.
  • External: this is the new feature that suggests links from posts or pages on other websites.

When clicking the External tab, the plugin will show you a table of the related or relevant posts that it found on other websites. You can also see which sentence relates to the post, and if you feel okay, you can click the Copy button (in the Actions column) to copy the link to insert into your content.

After doing that, you'll see the new links appear in the External Outbound report:

Of course, those links will be available in the plugin's reports under Slim SEO > Link Manager, so you can see all the available details about them, like status, anchor text, etc.

Now you can monitor those links easily to see which links are redirected, which ones are broken, and can fix them

What else I can expect?

Besides suggesting and monitoring links to external sites, Slim SEO Link Manager also helps you to maintain those links, to keep them always active. That means when you edit and update a permalink of a post on one site, all the links to that post on other connected sites will be updated automatically. This keeps the URL always fresh, correct and avoids broken or redirected links across your sites, which is quite hard to track and fix.

If you use a multisite network, the plugin also optimizes the performance a lot to reduce the external connections. But in any case, performance is our top priority and this functionality doesn't affect it. It's just better in the case of multisite versus multiple external sites.

With this feature, we hope building backlinks and maintaining them is not a hard task for everybody. If you haven't used this feature, please try it and let us know what you think in the comments. Also, don't forget to share the news with other people if you find it useful.
