renais.com website review

About 391 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.7 s faster on a phone.

Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Klaviyo, Shopify and Clarity and others), adding 1.4 MB and 602 ms of main-thread time.

3 images could be 138 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 450 ms faster on a phone.

A phone's processor spends 3.4 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Klaviyo costs a phone 211 ms of main-thread work and 334 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.

Shopify costs a phone 110 ms of main-thread work and 793 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.

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

6 files are served with short cache lifetimes, so returning visitors download them again (28 KiB).

10 long tasks block the main thread while loading, the longest for 116 ms. During a long task the page ignores taps.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

About 11 KiB of CSS is downloaded but never applied on this page.

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.

Your largest element takes 13.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “The Watson family vineyard in Northern France at sunset”.

The page becomes fully interactive after 13.8 s. Good is under 3.8 s.

Visually, the page fills in at 6.4 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 112 ms to 133 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

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

Your homepage downloads 2.7 MB in 253 requests on a phone: scripts 1.1 MB (105), other files 861 KiB (91) and images 565 KiB (19). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example rn-review-bottle-20260921.webp at 312 px wide, shown at 103 px. Resized copies would save about 3 KiB.

1 image (178 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.78 g of CO₂e: 93.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

8 visible links have no text or label, so screen readers cannot say where they go.

Elements with visible text labels do not have matching accessible names. (1 element).

Structured data found (Organization and WebSite) but with 1 problem, for example “WebSite: missing name”.

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

The homepage links to 38 pages on renais.com and 4 external pages.

Your Organization JSON-LD is missing logo, 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://renais.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.

We fetched 15 pages linked from your homepage (of 19 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Access to fetch at 'https://cdn.judge.me/reviews/reviews_for_carousel?reviews_selection=all&carousel_type=cards&star_ra…”.

2 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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.

The homepage carries about 454 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo 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 15 cookies, 1 of them by other companies (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.
