optimera.se website review

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.4 s.

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

69 files are served with short cache lifetimes, so returning visitors download them again (551 KiB).

11 images could be 303 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 500 ms faster on a phone.

About 396 KiB of JavaScript is downloaded but never used on this page.

7 third-party services load with your homepage (Google Tag Manager, Google Maps and Optanon and others), adding 1.7 MB and 147 ms of main-thread time.

ctfassets.net costs a phone 0 ms of main-thread work and 598 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.

Google Fonts costs a phone 0 ms of main-thread work and 454 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 long tasks block the main thread while loading, the longest for 137 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

About 45 KiB of CSS is downloaded but never applied on this page.

Polyfills for old browsers add 18 KiB JavaScript that modern phones do not need.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your homepage downloads 3.5 MB in 245 requests on a phone: other files 1.3 MB (130), scripts 993 KiB (63) and images 607 KiB (33). Under 2 MB keeps phones on slow connections fast.

1 image further down the page (38 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 1.00 g of CO₂e: 119.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 3 elements on the page fail this check, rated moderate by axe-core.

Contentinfo landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

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 contentinfo 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 on the page fails this check, rated moderate by axe-core.

Alternative text of images should not be repeated as text: 2 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (2 elements).

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 56 pages on optimera.se 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 https://www.optimera.se/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.

/, https://www.optimera.se/hitta-butik, https://www.optimera.se/varumarken and https://www.optimera.se/varumarken/timbra all use the title “Optimera - Bygghandel för proffs”. Search engines can't tell which page to show for a search, so each competes with the others.

https://www.optimera.se/hitta-butik, https://www.optimera.se/kund-hos-oss/kontakt, https://www.optimera.se/mangda-och-dimensionera, https://www.optimera.se/specialistomraden, https://www.optimera.se/aktuellt and https://www.optimera.se/varumarken and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.optimera.se/aktuellt, https://www.optimera.se/varumarken and https://www.optimera.se/varumarken/timbra have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.optimera.se/specialistomraden 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.

https://www.optimera.se/specialistomraden, https://www.optimera.se/aktuellt, https://www.optimera.se/varumarken, https://www.optimera.se/start/Villaeffekten and https://www.optimera.se/varumarken/timbra took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 42 found) and read each the way a search engine does.

11 of 33 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

Large scripts ship without source maps.

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.

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

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 202 words of visible text; thin pages give Google and first-time buyers little to go on.

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

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

Opening the homepage sets 5 cookies (measured from a US location before any click).

Loading the homepage contacts 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
