spectra.co website review

16 files are served with short cache lifetimes, so returning visitors download them again (1.5 MB).

About 766 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.1 s faster on a phone.

Your mobile performance score is 46. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Clarity and others), adding 1.1 MB and 831 ms of main-thread time.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

Google Tag Manager costs a phone 517 ms of main-thread work and 702 KiB of downloads while your page loads. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 20 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 340 ms faster on a phone.

A phone's processor spends 2.6 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

10 long tasks block the main thread while loading, the longest for 160 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need.

2 images could be 11 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Real visitors see the first content after 3.3 s (75th percentile). Good is under 1.8 s.

Your largest element takes 18.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Your teams depend on stable connectivity for collaboration,…”. Most of its time is element render delay (8.5 s).

Visually, the page fills in at 17.6 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 18.1 s. Good is under 3.8 s.

The first text or image appears after 4.0 s on a phone. Good is under 1.8 s.

Real visitors wait 3.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.7 s to 4.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 438 ms in total while the page loads. Good is under 200 ms.

2 images have no width and height attributes, so the layout jumps as each one loads.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 238 ms to 289 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.2 MB in 64 requests on a phone: scripts 2.0 MB (17), other files 1.7 MB (28) and images 302 KiB (12). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.18 g of CO₂e: 142.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

6 buttons have no accessible name, so screen readers announce just “button”.

12 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

4 tap targets are too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

There is no <h1>, so neither visitors nor Google get a clear main headline.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

A phone browser shows 1,119 words, but the HTML your server sends has only 0. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

6 of 12 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

2 errors were logged to the browser console while the page loaded, for example “jQuery is not defined”.

Large scripts ship without source maps.

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

There is no form on the homepage, so every lead has to click through to another page first.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

The homepage carries about 1,119 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, LinkedIn Insight and Meta Pixel and 1 more (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

Opening the homepage sets 10 cookies (measured from a US location before any click).

No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

Loading the homepage contacts 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
