eryma.com website review

Your mobile performance score is 87. Pages that score under 90 lose visitors before the first paint.

About 264 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 850 ms.

10 images could be 124 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

About 25 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.

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.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

Your largest element takes 3.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Eryma”.

The page becomes fully interactive after 3.9 s. Good is under 3.8 s.

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.45 g of CO₂e: 53.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Alternative text of images should not be repeated as text: 12 elements on the page fail this check, rated minor by axe-core.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 16 characters: “Homepage | Eryma”. Between 30 and 65 characters leaves room to say what you do and for whom.

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.

No XML sitemap at https://www.eryma.com/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at eryma.com/robots.txt, the first file search crawlers ask for.

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

The homepage links to 66 pages on eryma.com and 8 external pages.

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 /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.

/ and /en all use the title “Homepage | Eryma”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

/contact, /contact-eryma, /en, /notre-histoire, /nos-chiffres-cles and /nos-implantations and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

/nos-implantations 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 39 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

2 images are served at too low a resolution for sharp phone screens.

1 link go through two or more redirects, for example http://youtube.com/.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

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

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

Social proof on the homepage: 2 customer or partner logos. Pairing it with named testimonials or customer logos makes it far more convincing.

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

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

The homepage has only about 173 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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.

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.
