emmersion.ai website review

About 421 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.4 s faster on a phone.

12 files are served with short cache lifetimes, so returning visitors download them again (320 KiB).

Your mobile performance score is 59. Pages that score under 90 lose visitors before the first paint.

7 third-party services load with your homepage (Google Tag Manager, Facebook and Hubspot and others), adding 1.0 MB and 749 ms of main-thread time.

Google Tag Manager costs a phone 439 ms of main-thread work and 644 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.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 450 ms.

9 long tasks block the main thread while loading, the longest for 153 ms. During a long task the page ignores taps.

5 images could be 130 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 25 KiB JavaScript that modern phones do not need.

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 20.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Rosetta stone and TrueNorth certificate”.

The page becomes fully interactive after 20.8 s. Good is under 3.8 s.

Visually, the page fills in at 9.3 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 136 ms to 183 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 345 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.8 s to 1.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 87 requests on a phone: fonts 1.8 MB (6), scripts 1.2 MB (31) and images 209 KiB (21). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.95 g of CO₂e: 114.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 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: 27 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

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

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 29 pages on emmersion.ai and 22 external pages.

Your robots.txt shuts out ChatGPT (ChatGPT-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

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.

There is no https://emmersion.ai/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.

robots.txt blocks GPTBot, ClaudeBot and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

https://emmersion.ai/language-certification and https://emmersion.ai/language-certification/buy use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://emmersion.ai/products/webcape, whose canonical is https://emmersion.ai/higher-education/webcape. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://emmersion.ai/language-certification/buy 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 13 pages linked from your homepage and read each the way a search engine does.

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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

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 350 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, HubSpot and LinkedIn Insight and 1 more (measured from a US location before any click). A consent tool (HubSpot cookie banner) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 15 cookies, 5 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
