<p>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.</p>
<p><strong>Purrlink solves this.</strong> 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.</p>
<p><strong>Before:</strong></p>
<blockquote>
<p>“Taking care of [cats] requires attention…”</p>
</blockquote>
<p><strong>After:</strong></p>
<blockquote>
<p>“Taking care of cats requires attention. If you’re just starting out, check out our <strong>[Beginner’s Guide to Cat Care]</strong> for helpful tips.”</p>
</blockquote>
<h4>Why Purrlink?</h4>
<ul>
<li><strong>Better for SEO</strong> — Contextual internal links help search engines understand your site structure and pass link equity between pages</li>
<li><strong>Better for readers</strong> — Bridge sentences guide visitors to related content naturally, increasing pageviews and time on site</li>
<li><strong>Saves time</strong> — What takes minutes to write manually, Purrlink generates in seconds</li>

<h3>External Services</h3>
<p>This plugin connects to the <strong>Google Gemini API</strong> to generate bridge sentences using AI.</p>
<p>When you click “Generate” in the Purrlink sidebar, the following data is sent to Google’s servers:</p>
<ul>
<li>The text you selected in the editor (source context)</li>
<li>The title and excerpt of the target post you chose to link to</li>
<li>Your website profile settings (website name, niche, target audience, brand voice)</li>
<li>Your persona settings (tone, writing style, language notes)</li>

<p>No data is sent automatically — it only happens when you explicitly click “Generate” or “Regenerate”.</p>
