opisnet.com website review

25 images could be 9.7 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 15.6 s faster on a phone.

About 771 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.8 s.

Your mobile performance score is 33. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 5.4 s on main-thread work while loading, 2.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google Tag Manager, Wistia and Hubspot and others), adding 1.4 MB and 1.9 s of main-thread time.

Google Tag Manager costs a phone 931 ms of main-thread work and 850 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.

11 files are served with short cache lifetimes, so returning visitors download them again (196 KiB).

Polyfills for old browsers add 38 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 450 ms faster on a phone.

Wistia costs a phone 428 ms of main-thread work and 280 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.

62 KiB could be saved by minifying JavaScript.

20 long tasks block the main thread while loading, the longest for 347 ms. During a long task the page ignores taps.

About 42 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

8 KiB could be saved by minifying CSS.

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.

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.

The first text or image appears after 8.4 s on a phone. Good is under 1.8 s.

Your largest element takes 67.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 71.0 s. Good is under 3.8 s.

Visually, the page fills in at 8.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 1.2 s in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 101 ms to 126 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 965 ms for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.4 s to 2.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 20.6 MB in 151 requests on a phone: images 18.1 MB (45), scripts 1.6 MB (39) and fonts 773 KiB (28). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 5.84 g of CO₂e: 700.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 button has no accessible name, so screen readers announce just “button”.

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

3 tap targets are too small or too close together to hit reliably with a finger.

Elements must only use permitted ARIA attributes: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 25 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.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Headings skip levels (h1 → h3, h3 → h5 and h3 → h5), which makes the page harder to scan with a screen reader.

Your title is only 20 characters: “Energy Prices | OPIS”. Between 30 and 65 characters leaves room to say what you do and for whom.

Structured data found (BreadcrumbList, Organization, WebPage and WebSite) but with 1 problem, for example “BreadcrumbList: itemListElement is an empty list”.

20 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

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

1 link has no real href, so search engines can't follow it.

The homepage links to 229 pages on opisnet.com and 23 external pages.

There is no https://www.opis.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.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://www.opis.com/who-we-help, whose canonical is https://www.opis.com/who-we-help/overview. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 145 found) and read each the way a search engine does.

12 of 21 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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.

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 1,038 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 13 cookies (measured from a US location before any click).

Loading the homepage contacts 29 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
