Internal Link Juicer

Internal Link Juicer is a WordPress plugin built to simplify and speed up internal linking — a key element of effective on-page SEO. It uses a semi-automated approach that lets you define linking rules and keywords, then applies those rules sitewide to create contextual internal links that help distribute authority and improve crawlability.
Instead of manually approving every suggestion, you define keyword-to-post associations and the plugin scans your content to inject links where appropriate. It’s optimized for performance so it handles large content repositories without adding noticeable load to your front end.
Pricing
There’s a functional Free Basic tier, while the paid Pro plans unlock advanced controls and scaling options suitable for agencies and larger sites.
1 Site: $69.99 / year
5 Sites: $149.99 / year
10 Sites: $189.99 / year
Lifetime Option: Typically available starting around $249 for a single site.
Internal Link Juicer is especially useful for sites with extensive archives where manual linking would be impractical. It’s a power-user tool: the more thought you put into keyword rules and target selection, the greater the SEO benefit across your site.
