About this plugin
Internal links are one of the easiest ways to improve your SEO and reduce bounce rate. But manually writing contextual sentences around each link is tedious — and just dropping a link on a keyword looks unnatural.
Purrlink solves this. It uses AI to generate a “bridge sentence” that naturally introduces your internal link, so it reads like part of your content — not an afterthought.
Before:
>
“Taking care of [cats] requires attention…”
After:
>
“Taking care of cats requires attention. ”
Why Purrlink?
- Better for SEO — Contextual internal links help search engines understand your site structure and pass link equity between pages
- Better for readers — Bridge sentences guide visitors to related content naturally, increasing pageviews and time on site
- Saves time — What takes minutes to write manually, Purrlink generates in seconds

External Services
This plugin connects to the Google Gemini API to generate bridge sentences using AI.
When you click “Generate” in the Purrlink sidebar, the following data is sent to Google’s servers:
- The text you selected in the editor (source context)
- The title and excerpt of the target post you chose to link to
- Your website profile settings (website name, niche, target audience, brand voice)
- Your persona settings (tone, writing style, language notes)
No data is sent automatically — it only happens when you explicitly click “Generate” or “Regenerate”.
