What is internal linking and what is it good for?

An internal link is a link that is placed on a page which links to another page within the same domain. Internal links have an extremely high value when it comes to SEO and also the general optimization of websites.

Internal links…

  • have an immense influence on SEO
  • help search engines find new content quickly
  • help search engines to better interpret and classify the content of a page
  • can distribute traffic to well converting subpages

On our website we created a comprehensive guide about internal linking, where you will find a lot of knowledge and useful tips.

Will the plugin slow down my site?

Absolutely not. The Internal Link Juicer was explicitly designed for fast loading times and maximum performance. It solves the problem of generating links using its own index. This prevents additional delays while loading the frontend.

Will the plugin improve my search engine rankings?

Of course no guarantee can be given for this. But building internal links within a website is a basic discipline for onpage SEO. Internal links help search engines to find your content faster and understand it better. Both are important parts for good rankings. We help you to massively improve the structure of intern links and even automate the whole process stress-free.

Does the plugin change my content?

No – the plugin has its own index, where links that need to be created are efficiently stored. Whenever a page is rendered, the links are generated before output and your existing content is enriched with them. The content itself is not manipulated by the plugin.

Does the plugin work with content generated from shortcodes?

Yes – the plugin works with content (within posts or pages) that gets generated through shortcodes.

Can I disable linking on specific pages?

Yes, at any time! With our blacklist feature you can easily disable the generation of links on individual pages.

Can I change the style of the auto generated links?

Yeah, definitely. With the help of our templating system you can change the output of your generated links in no time at all.

Is Internal Link Juicer compatible with translation plugins?

Yes – we provide an own compatibility mode for WPML and Polylang as this has been requested by many users. We are planning to support more 3rd party plugins soon – requests always appreciated!

How can I automate the setting of keywords if I have a lot of posts?

We understand that, depending on the size of your website, it can be difficult to enter keywords manually. For this reason, we implemented the possibility to export all linkable content in the import/export area, enrich it with your own sources, and re-import it afterward.

The Pro version also provides a direct import of post (and term) titles or, if installed, Yoast SEO and RankMath « focus keywords ».

Easy to use but the imported .csv file is hard to edit on excel.

I did not realize the importance of internal links. This executes them beautifully and saves a tremendous amount of time. I created some problems which I resolved. However, I contacted support and they responded rapidly with ‘fixes’ and explanations. They also offered to temporarily assume the admin role to assist. WONDERFUL TOOL AND SUPPORT.
