Compare side by sideOne score from every part of this review. How it works
Speed
Mobile performance score: 86
86/100Your mobile performance score is 86. Pages that score under 90 lose visitors before the first paint.
Render-blocking requests
800 ms4 files block the first paint until they finish downloading. Deferring or inlining them could save about 800 ms.
Improve image delivery
342 KiB6 images could be 342 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.
Use efficient cache lifetimes
50 ms · 241 KiB28 files are served with short cache lifetimes, so returning visitors download them again (241 KiB).
Font display
50 msWeb fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).
3 third-party services on the page
3 third-party services load with your homepage (Cloudflare, Google Fonts and pvpbet.io), adding 341 KiB and 12 ms of main-thread time.
Reduce unused CSS
26 KiBAbout 26 KiB of CSS is downloaded but never applied on this page.
Legacy JavaScript
10 KiBPolyfills for old browsers add 10 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Core Web Vitals
Fails Core Web Vitals for real visitors

Images and page weight
1 image in older formats
1 image (255 KiB) is 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.
About 0.3 g of CO₂ per visit
0.30 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.30 g of CO₂e: 35.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
3 checks passed
Page weight: 1.0 MB in 42 requests
1.0 MBYour homepage downloads 1.0 MB in 42 requests on a phone: images 776 KiB (17), scripts 90 KiB (10) and fonts 81 KiB (4). That is a lean page.
Images load when needed
Images below the first screen wait until the visitor scrolls to them.
Images are sized for phones
No image is downloaded at more than three times the size it is drawn on a phone.
Accessibility
20 text elements with low contrast
20 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.
Links look like plain text
1 link inside paragraphs relies on colour alone to stand out.
Scrollable region must have keyboard access (1 element)
Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.
1 image without alt text
1 image has no alt text, which hurts accessibility and image search.
Main landmark should not be contained in another landmark (1 element)
Main landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.
Document should not have more than one main landmark (1 element)
Document should not have more than one main landmark: 1 element on the page fails this check, rated moderate by axe-core.
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)
Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.
All page content should be contained by landmarks (1 element)
All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.
1 link without text
1 visible link has no text or label, so screen readers cannot say where it goes.
1 tap target too small
1 tap target is too small or too close together to hit reliably with a finger.
Headings skip levels
Headings skip levels (h2 → h4), which makes the page harder to scan with a screen reader.
<td> elements in a large <table> do not have table headers.
<td> elements in a large <table> do not have table headers. (2 elements).

44 automated accessibility rules passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 54 WCAG 2.2 A/AA and best-practice rules on the phone render: 44 passed and 10 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No favicon declared
No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

The homepage links to 37 pages on refermo.co and 9 external pages.

AI search readiness
No Organization structured data

No llms.txt
There is no https://five88z.net/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.

No calls to action

No social proof

No direct contact details

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