<p>CloudScale SEO AI Optimizer is a completely free SEO plugin built for technical bloggers and site owners who want full control without the overhead of Yoast or RankMath. There is no Pro version, no upsells, no feature gates, and no licence keys.</p>
<p>It handles the essentials cleanly and adds a full AI toolkit that uses either the Anthropic Claude API or the Google Gemini API to generate meta descriptions, ALT text, summaries, SEO scores, focus keywords, internal links, and related articles — all from WP Admin, with no extra subscriptions required.</p>

<strong>Data sent:</strong> The URL of the Google Font stylesheet registered on your site. No personal data or post content is transmitted.<br />
<strong>Purpose:</strong> To copy font files from Google’s CDN to your own server, eliminating the external Google Fonts request from your frontend pages (improves GDPR compliance and Core Web Vitals).</p>
<p>Google Privacy Policy: https://policies.google.com/privacy<br />
Google Terms of Service: https://policies.google.com/terms</p>
<h4>Broken Link Checker (server-side URL probing)</h4>
<p><strong>What it does:</strong> When you use the Broken Link Checker in WP Admin, the plugin extracts all outbound hyperlinks from your published posts and pages, then sends an HTTP HEAD request from your server to each unique URL to check its status.<br />
<strong>Data sent:</strong> Only the URL itself is fetched — no post content, no user data. Standard HTTP headers (User-Agent identifying your site) are sent with each request.<br />
<strong>When it fires:</strong> Only when you open the Broken Link Checker tab and start a scan. No automatic or scheduled scanning.<br />
<strong>Note:</strong> <code>sslverify</code> is disabled for these requests so that sites with expired or self-signed certificates can be checked. Requests to loopback, link-local, and private IP ranges are blocked.</p>
<p>There is no separate terms of service for outbound HTTP HEAD requests — your server is simply fetching publicly reachable URLs listed in your own content.</p>
