spacedaily.com website review

A phone's processor spends 13.5 s on main-thread work while loading, 6.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Pubmatic costs a phone 1.0 s of main-thread work and 98 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

8 third-party services load with your homepage (Pubmatic, Rubicon Project and script.ac and others), adding 1.4 MB and 2.8 s of main-thread time.

20 images could be 1.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

Your mobile performance score is 60 (desktop: 68). Pages that score under 90 lose visitors before the first paint.

108 files are served with short cache lifetimes, so returning visitors download them again (629 KiB).

Rubicon Project costs a phone 582 ms of main-thread work and 83 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 561 KiB of JavaScript is downloaded but never used on this page.

script.ac costs a phone 333 ms of main-thread work and 90 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.

20 long tasks block the main thread while loading, the longest for 317 ms. During a long task the page ignores taps.

Google Tag Manager costs a phone 262 ms of main-thread work and 356 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.

Google/Doubleclick Ads costs a phone 189 ms of main-thread work and 337 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.

Polyfills for old browsers add 23 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 150 ms.

About 31 KiB of CSS is downloaded but never applied on this page.

4 KiB could be saved by minifying JavaScript.

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.

4 KiB could be saved by minifying CSS.

The page becomes fully interactive after 46.6 s. Good is under 3.8 s.

Scripts block taps and scrolling for 2.1 s in total while the page loads. Good is under 200 ms.

Visually, the page fills in at 5.9 s (Speed Index). Good is under 3.4 s.

Your largest element takes 3.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 129 ms to 114 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.3 MB in 1,079 requests on a phone: scripts 1.7 MB (72), images 1.4 MB (294) and other files 745 KiB (545). Under 2 MB keeps phones on slow connections fast.

2 images are downloaded at several times the size a phone draws them, for example mir-space-station-1024x538.png at 1,024 px wide, shown at 112 px. Resized copies would save about 486 KiB.

3 images (587 KiB) are JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 1.22 g of CO₂e: 145.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

The homepage links to 81 pages on spacedaily.com and 6 external pages.

Your Organization JSON-LD is missing url, sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

There is no https://spacedaily.com/llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

https://spacedaily.com/long-reads and https://spacedaily.com/archive have no meta description, so Google writes the search snippet from whatever text it finds.

https://spacedaily.com/newsletter has under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

We fetched 15 pages linked from your homepage (of 38 found) and read each the way a search engine does.

53 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

4 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 (Not Found)”.

Chrome logged issues while loading the page (“Cookie”).

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.

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 800 words of visible text.

Before a visitor clicks anything, the page loads Criteo, Google Ads, Google Analytics, Google Tag Manager and Taboola 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 9 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 57 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
