WP Speed of Light

WP Speed of Light is a WordPress performance plugin built by Paris-based developer JoomUnited, who also maintain WP Media Folder, WP File Download, and roughly a dozen other WordPress and Joomla extensions. The plugin ships a static page-caching engine, asset grouping and minification for CSS and JavaScript, lazy loading for images and iframes, Gzip and Brotli output compression via .htaccess, an automatic cache cleaner tied to content updates, a database cleaner for post revisions, auto-drafts, trashed posts, transients, and orphaned metadata, and a built-in page speed test that reports a simple before/after score. Version 3.0 added Core Web Vitals reporting so site owners can track LCP, CLS, and INP directly inside the WordPress admin rather than bouncing to PageSpeed Insights. A free tier lives on wordpress.org; the paid addon unlocks multisite support, Google PageSpeed Insights integration, advanced CSS optimization, and priority support.

The typical buyer is a WordPress site owner on shared or managed hosting who wants a single plugin for caching plus cleanup instead of stacking WP Rocket with a separate database cleaner, plus agencies that manage dozens of client sites and want a consistent performance baseline. Affiliate angles that convert well are caching-plugin comparisons against WP Rocket, LiteSpeed Cache, W3 Total Cache, and FlyingPress, as well as tutorial content about cleaning up a slow WordPress admin. JoomUnited also bundles WP Speed of Light with its full plugin catalog in a WordPress Developer Bundle, which raises effective order value for publishers covering agency-focused workflows.

The affiliate program is run directly by JoomUnited at joomunited.com/join-the-affiliate-program, covering every JoomUnited product including WP Speed of Light, WP Media Folder, WP File Download, and the Developer Bundle. Publishers sign up through the on-site form, get a dashboard with tracked links, banners, and product-specific deeplinks, and can pull reporting by product, order, and payout status. JoomUnited does not route through CJ, Impact, or ShareASale; tracking, cookies, and payouts live inside its own platform.

Commission is 20% of each sale on the first tier, stepping up to 25% after a publisher clears USD 500 in accrued commission within a month. The cookie is 30 days, and payouts run monthly via PayPal on the first of each month, subject to a USD 50 minimum threshold. Commissions validate after JoomUnited's refund window closes on the referred order, which mirrors the plugin license's money-back guarantee; refunded orders are clawed back. Self-referrals and coupon-site traffic are excluded under the program terms, and a publisher must keep the affiliate account active to keep accruing commission on renewals. Because every JoomUnited plugin sits under the same program, a referred buyer who later purchases a second plugin still attributes back to the original publisher.
