cosmossport.gr website review

28 images could be 3.3 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.0 s faster on a phone.

About 843 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.9 s faster on a phone.

Your mobile performance score is 35. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 6.8 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 6,034 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google CDN, Accessibe Accessibility Overlay and Klaviyo and others), adding 1.3 MB and 1.1 s of main-thread time.

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

50 files are served with short cache lifetimes, so returning visitors download them again (569 KiB).

About 103 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

17 long tasks block the main thread while loading, the longest for 369 ms. During a long task the page ignores taps.

Google CDN costs a phone 305 ms of main-thread work and 357 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 32 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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.

Your largest element takes 28.2 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Box Now”.

The page becomes fully interactive after 33.6 s. Good is under 3.8 s.

Visually, the page fills in at 9.7 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.2 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.9 s on a phone. Good is under 1.8 s.

Real visitors wait 239 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 203 ms to 217 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.2 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.2 MB in 126 requests on a phone: images 5.7 MB (51), scripts 2.1 MB (46) and fonts 177 KiB (3). Under 2 MB keeps phones on slow connections fast.

2bdd9eeb6138d08f30905fb32bd0eb4827aa49f1_kv_terrex_HpBanner_ weighs 655 KiB. On a phone connection a single image that size takes seconds.

10 images (2.8 MB) 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.

2bdd9eeb6138d08f30905fb32bd0eb4827aa49f1_kv_terrex_HpBanner_ is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 2.31 g of CO₂e: 277.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Interactive controls must not be nested: 4 elements on the page fail this check, rated serious by axe-core.

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

Scrollable region must have keyboard access: 3 elements on the page fail this check, rated serious by axe-core.

Some lists contain elements other than list items, which screen readers announce wrongly.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

1 frame has no title, so screen-reader users cannot tell what it contains.

All page content should be contained by landmarks: 56 elements on the page fail this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

ARIA role should be appropriate for the element: 4 elements on the page fail this check, rated minor by axe-core.

Users should be able to zoom and scale the text up to 500%: 1 element on the page fails this check, rated minor by axe-core.

Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.

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

Your title is 113 characters, so Google will cut it off around 60: “Cosmossport.gr | Το Νο1 Ηλεκτρονικό Κατάστημα Αθλητικών ειδών στην Ελλάδα! | Αθλητικά Ρού…”.

Your meta description is 182 characters; Google truncates after about 160, so the end of your pitch is cut.

10 links have no real href, so search engines can't follow them.

The homepage links to 1,137 pages on cosmossport.gr and 11 external pages.

/el/9134-nees-afikseis, /el/9122-nees-afikseis, /el/9078-nees-afikseis, /el/33020-nees-afikseis-paidika, /el/10425-nees-afikseis and /el/10443-nees-afikseis are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

/el/33020-nees-afikseis-paidika has no meta description, so Google writes the search snippet from whatever text it finds.

/el/loyalty has no <h1> headline, so visitors and search engines get no clear main topic.

/el/loyalty, /el/9122-nees-afikseis, /el/33020-nees-afikseis-paidika, /el/10425-nees-afikseis and /el/10443-nees-afikseis took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 197 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=149012771&tm=gtm002&Ver=2&mid=66005055-d3df-47b3-8bb6-77c6a8cae8db&bo=1&sid=b9146f00d52c11f1a599694eb248249f&vid=b91460a0d52c11f19f65b755bb25ada0&vids=1&msclkid=N&gtm_.

24 of 68 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

1 image is served at too low a resolution for sharp phone screens.

Large scripts ship without source maps.

HSTS is set, but max-age is 182 days; one year is the recommended minimum.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

cosmossport.gr has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

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

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage has only about 166 words of visible text; thin pages give Google and first-time buyers little to go on.

The homepage shows no opening hours. If customers visit or call, show when.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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

DMARC is set to p=none, so mail pretending to be cosmossport.gr is still delivered. Reports are on, so moving to quarantine is the next step.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Before a visitor clicks anything, the page loads Google Analytics, Google Tag Manager, Klaviyo and Microsoft Ads (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 6 cookies (measured from a US location before any click).

Loading the homepage contacts 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
