Text/HTML Ratio Test
Excellent
Measured Value: 50.4%
Metric Score: 100%
Text-to-HTML ratio measures visible text content as a percentage of total HTML markup. Modern CMS and framework-heavy sites (Joomla, WordPress, React, etc.) typically produce 5–15% due to component scaffolding, utility CSS classes, and inline SVGs. A ratio above 15% is excellent. While not a direct ranking factor, a low ratio signals DOM bloat, inline code, and excessive markup that affects Core Web Vitals, crawl efficiency, and overall page weight.
Your text-to-HTML ratio is 50.4% — within the ideal 15–55% range.
HTML Headings
Good
Metric Score: 83%
H1 status is the existence of any content inside h1 tag. Although not important like Meta titles and descriptions for search engine ranking but still a good way to describe your contents in search engine result. H2 status is less important but should be used for proper understanding of your website for visitor.

Uses Optimized Images
Excellent
Metric Score: 100%
Serve images in modern formats (WebP, AVIF), compress them appropriately, and deliver correctly sized images for each viewport. Unoptimized images are often the single largest source of page weight, directly increasing load time and data usage. Use responsive images with srcset, lazy-load offscreen images, and apply lossy or lossless compression to reduce file size without visible quality loss.
No unoptimized images detected. This is optimal.
Unoptimized Images: No unoptimized images detected
Uses Text Compression
Excellent
Metric Score: 100%
Enable text-based resource compression (Gzip or Brotli) on your server for HTML, CSS, JavaScript, SVG, and JSON responses. Compression typically reduces transfer size by 60–80%, significantly improving load time. Configure your web server or CDN to compress all text-based MIME types and verify with response headers (Content-Encoding: gzip or br).
No uncompressed text resources detected. This is optimal.
Uncompressed Resources: No uncompressed text resources detected
Uses Rel Preconnect
Excellent
Metric Score: 100%
Use <link rel="preconnect"> to establish early connections to important third-party origins, saving DNS lookup, TCP handshake, and TLS negotiation time. This is especially valuable for fonts, analytics, CDN assets, and API endpoints loaded early in the page lifecycle. Limit preconnects to 2–4 critical origins to avoid connection contention.

Redirects: No redirects detected
Efficient Animated Content
Excellent
Metric Score: 100%
Replace large GIF animations with video formats (MP4, WebM) which are significantly smaller and can be hardware-decoded. Animated GIFs are extremely inefficient — a 10-second GIF can easily exceed 10 MB while the equivalent MP4 may be under 500 KB. Use <video autoplay loop muted playsinline> as a drop-in replacement, and consider CSS animations or Lottie for UI animations.
No inefficient animated content detected. This is optimal.
Inefficient Animated Content: No inefficient animated content detected
Non-Composited Animations
Excellent
Metric Score: 100%
Non-composited animations run on the main thread instead of the GPU, causing jank and poor visual performance. Use CSS properties like transform and opacity for animations, which can be GPU-accelerated and run on the compositor thread.
Your page has 0 non-composited animations on mobile. This is optimal.
Non-Composited Animations: No non-composited animations detected

Uses Rel Preload
Excellent
Metric Score: 100%
Use <link rel="preload"> to prioritize fetching critical resources that are discovered late in the page load (e.g., fonts referenced in CSS, hero images, key scripts). Preloading tells the browser to start downloading these resources immediately rather than waiting until they are naturally discovered during parsing. Limit preloads to 3–5 truly critical resources to avoid bandwidth contention.
No resources identified for preload. This is optimal.
Resources to Preload: No resources identified for preload
Duplicated JavaScript

Long Tasks: No long tasks detected
Metric Score: 80%
Estimated savings: 920.2 KB
Cache-Control headers tell browsers how long to reuse a resource before re-fetching it. Short or missing TTLs force unnecessary network requests on repeat visits, slowing page load. Score is based on first-party wasted bytes plus 15% of third-party waste (0 KB = 100, <= 50 KB = 90, <= 150 KB = 80, <= 300 KB = 65, <= 750 KB = 40). Third-party resources carry reduced weight since they are outside your direct control.

No legacy JavaScript polyfills detected for modern browsers.
Legacy Scripts: No legacy JavaScript polyfills detected
Avoid Forced Reflow
Excellent
Metric Score: 100%
A forced reflow (layout thrashing) happens when JavaScript reads a layout property — such as offsetWidth, offsetHeight, getBoundingClientRect(), or getComputedStyle() — right after changing the DOM or CSS styles. This forces the browser to stop and recalculate the page layout synchronously, blocking the main thread and causing visible jank or frozen interfaces. Scored by total reflow time: 0ms = 100, ≤30ms = 90, ≤100ms = 75, ≤250ms = 50, ≤500ms = 30, >500ms = 15.
No significant forced reflow detected. Page avoids layout thrashing.
Reflow Sources: No layout thrashing detected
How to Fix Forced Reflow:
- Batch DOM reads before writes — read all layout properties first, then make all DOM changes.
- Use
requestAnimationFrame()— schedule visual updates to avoid mid-frame style recalculations. - Avoid reading layout props in loops — reading
offsetWidth,getBoundingClientRect(), orgetComputedStyle()inside a loop forces layout on every iteration. - Prefer CSS transform/opacity — these properties are compositor-only and never trigger layout.
- Use a FastDOM library — batches reads and writes automatically.
Metric Score: 60%
Network dependency chains create waterfall delays where each resource must wait for its parent to finish loading. Scored by chain duration (<=500ms = 100, <=1s = 90, <=2s = 80, <=3s = 70, <=5s = 60) with penalties for deep chains (depth 3+). Reduce chain depth by preloading key resources, inline critical assets, and defer non-critical downloads.
Mobile: 2005ms, depth 4 · Desktop: 2836ms, depth 4.

| 1.5 MB - 2.5 MB | -20 | Likely impactful on load/parse |
| > 2.5 MB | -30 | High performance risk |
Which libraries were found? None detected.
Why this can happen: Scripts were detected, but we did not match known library signatures (common with bundled/minified/custom builds).
Is that good? Usually yes—if all required features work. Fewer dependencies generally means better performance, fewer security updates, and easier maintenance.
How to keep this score high: prefer vanilla JS/web APIs, remove dead scripts, and avoid adding libraries for one-off utilities.
External scripts carry added performance and security risk—keep third-party JS minimal. See “Vulnerable Libraries” for security follow-up.

What Does "Liquid Purple" mean?
noun | / LIK-wid PUR-pul /
-
(biochemistry) Also known as visual purple or rhodopsin — a light-sensitive receptor protein found in the rods of the retina. It enables vision in dim light by transforming invisible darkness into visible form. Derived from the Greek rhódon (rose) and ópsis (sight), its name reflects its delicate pink hue and vital role in perception.
-
(modern usage) Liquid Purple — a digital marketing agency specializing in uncovering unseen opportunities and illuminating brands hidden in the digital dark. Much like its biological namesake, Liquid Purple transforms faint signals into clear visibility — revealing what others overlook and bringing businesses into the light.
Origin: From the scientific term rhodopsin, discovered by Franz Christian Boll in 1876; adopted metaphorically by a marketing firm dedicated to visual clarity in the age of algorithms.
