Meta Description

Excellent

Metric Score: 100%

Description is the full interpretation of your website content and features. Most often it is a short paragraph that describe what are features and information provided by the website to its visitors. You may consider it a advertising of your website. Although not important for search engine ranking but very important for hits or visits through search engine results. Description should be less than 150 character because search engine shows this length of paragraph on search result. And every page of website should contain an unique description to avoid description duplication. Description is the definition of your website for user experience so form it as complete but short and precise illustration of your website.

Your meta description is between 50 and 155 characters. It's fine.

Meta Keywords

At Risk

Metric Score: 0%

This is an informational metric and does not affect your overall score. Meta keywords are not used by Google for search ranking. However, some search engines (e.g. Bing) may still reference them as a spam signal, and they can serve as useful organizational metadata for your content strategy.

Your site does not have any meta keywords.

Keywords:
Length: 0

Keyword Usage

At Risk

Metric Score: 0%

This is an informational metric and does not affect your overall score. Keyword usage analysis shows how well your meta keywords align with your actual page content. While meta keywords are not a Google ranking factor, understanding keyword-to-content alignment is useful for content strategy and organization.

Meta Keyword	In Content

Text/HTML Ratio Test

Excellent

Measured Value: 25.3%

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 25.3% — within the ideal 15–55% range.

HTML Headings

Excellent

Metric Score: 99%

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.

Good heading structure.

Sitemap

Excellent

Metric Score: 100%

Sitemap is a xml file which contain full list of your website urls. It is used to include directories of your websites for crawling and indexing for search engine and access for users. It can help search engine robots for indexing your website more fast and deeply. It is roughly an opposite of robots.txt. You can create a sitemap.xml by various free and paid services or you can write it with proper formatting. Also keep these things in mind: 1) Sitemap must be less than 10 MB (10,485,760 bytes) and can contain maximum 50,000 urls. If you have more urls than this, create multiple sitemap files and use a sitemap index file. 2) Put your sitemap in the website root directory and add the url of your sitemap in robots.txt. 3) sitemap.xml can be compressed using gzip for faster loading.

Your site has a sitemap.

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 Text Resources: N/A (Mobile), N/A (Desktop)

Your page has 0 redirects on mobile. This is optimal.

Redirects: N/A (Mobile), N/A (Desktop)

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.

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.

Efficient Cache Policy

Excellent

Metric Score: 90%

Estimated savings: 252.3 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.

Cache policy is efficient. 1 first-party resource (10.5 KB wasted). 8 third-party resources (241.9 KB wasted, weighted at 15%).

Avoid Forced Reflow

At Risk

Metric Score: 58%

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.

Forced reflow detected (132.4 ms). Batch DOM reads before writes, use requestAnimationFrame() for visual updates, avoid reading layout properties inside loops, and prefer CSS transform/opacity for animations.

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(), or getComputedStyle() 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.

Network Dependency Tree

JavaScript Libraries Detected

Excellent

Metric Score: 95%

Detects known JavaScript libraries via signature matching and supplements results with script payload/network context. Signature misses can occur with bundled or custom builds; smaller, intentional dependencies (especially third-party scripts) usually improve performance, maintainability, and security.

No external JavaScript libraries detected. This is excellent if your site works as intended without them. Script payload observed: 343.8 KB across 15 script requests. Scripts were detected, but Lighthouse did not match them to known library signatures. This can happen with custom bundles, renamed files, or inlined/compiled vendor code.

Observed script payload: 343.8 KB across 15 script requests. External scripts: 0

Detected JavaScript libraries: 0 found

Detected Count	Score Threshold	Interpretation	Status
0	100	No external libs (excellent if intentional)	Excellent
1 - 3	100	Lean dependency footprint	Excellent
4 - 5	85	Reasonable, review overlap	Warning
6 - 7	65	High dependency count	Warning
8+	40	Too many dependencies	At Risk

Script Payload (KB)	Extra Score Adjustment	Reason
0 - 700 KB	0	Generally manageable payload

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 website management 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 web development firm dedicated to visual clarity in the age of algorithms.
