gpio.com website review

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

11 images could be 187 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 350 ms faster on a phone.

About 11 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

4 third-party services load with your homepage (Shopify, Mailchimp and intuit.com and others), adding 232 KiB and 54 ms of main-thread time.

14 files are served with short cache lifetimes, so returning visitors download them again (22 KiB).

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

3 KiB could be saved by minifying JavaScript.

Your largest element takes 5.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image. Most of its time is resource load delay (2.4 s).

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' largest content (lcp) went from 1.1 s to 1.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Visually, the page fills in at 5.3 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 5.3 s. Good is under 3.8 s.

The first text or image appears after 2.2 s on a phone. Good is under 1.8 s.

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

2 images further down the page (48 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.48 g of CO₂e: 57.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

ARIA attributes must conform to valid values: 6 elements on the page fail this check, rated critical by axe-core.

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

34 images have no alt text, which hurts accessibility and image search.

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

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

No Open Graph image, 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.

The homepage links to 39 pages on gpio.com and 1 external page.

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.

https://gpio.com/collections/filters, https://gpio.com/collections/notch-filters, https://gpio.com/collections/low-pass-filters, https://gpio.com/collections/attenuators, https://gpio.com/collections/rf-adapters-and-connectors and https://gpio.com/collections/frequency-doubler and 2 others have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example https://gpio.com/blogs/news/an-important-note-about-shipping, whose canonical is https://gpio.com/blogs/news/shipping. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://gpio.com/collections/attenuators and https://gpio.com/pages/contact-us have 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 22 found) and read each the way a search engine does.

9 of 17 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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

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.

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 320 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (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 11 cookies (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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
