OnPage Speed Checker

Check PageSpeed Insights performance for homepage, pages, and posts directly from your WordPress dashboard.

fepo

fepo analyzes your website and reports concrete optimization potential — without changing a single file on your site.
What you get:
<ul>
<li>Performance score — Lighthouse + PageSpeed Insights, Core Web Vitals (LCP, INP, CLS), real-user data (CrUX)</li>
<li>AI Visibility (GEO score) — checks whether ChatGPT, Perplexity, and Google AI Overviews can read your content (Schema.org, robots.txt, structured content)</li>
<li>Fonts — how many KB you could save with subsetting / preloading</li>
<li>CSS — how much unused CSS is loaded</li>
<li>Images — which images can be converted to AVIF / WebP and the resulting savings</li>
<li>GDPR check (EU/DACH only) — which trackers fire before the user has given consent</li>
</ul>
The first audit is free — no account, no API key, no credit card. Click one button and you get a full performance and GEO breakdown.
For the full report — sandbox preview, optimized HTML download, waterfall analysis, security headers, accessibility (WCAG), DOM hygiene, and more — register for free at the fepo Portal.
The plugin does not modify your website. It is purely diagnostic — no files are changed, no CSS/JS is rewritten, no caching is configured. Your site stays exactly as it was.
<h3>External services</h3>
This plugin connects to portal.fepo.app, an external service operated by fepo, to perform the audit.
What is sent and when:
<ul>
<li>When you click “Start audit”: your site URL, WordPress version, PHP version, active theme name and version, list of active plugin slugs, site locale, and plugin version.</li>
<li>When you optionally register: your email address (encrypted at rest, used only for sending the login link).</li>
</ul>
What is NOT sent:
<ul>
<li>No personal data of your visitors</li>
<li>No content from posts, pages, or comments</li>
<li>No database contents</li>
<li>No file contents</li>
</ul>
The audit itself is performed by fepo’s server fetching your site’s public URLs (like any browser would). No private endpoints are accessed.
Users must explicitly consent to data transmission via a checkbox before the first audit. The consent is stored locally and can be revoked at any time by deactivating the plugin.
