nblocks.dev website review

Your mobile performance score is 85. Pages that score under 90 lose visitors before the first paint.

6 third-party services load with your homepage (Google Tag Manager, Cookiebot and ts.net and others), adding 724 KiB and 504 ms of main-thread time.

Google Tag Manager costs a phone 424 ms of main-thread work and 504 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.

About 276 KiB of JavaScript is downloaded but never used on this page.

25 files are served with short cache lifetimes, so returning visitors download them again (221 KiB).

5 long tasks block the main thread while loading, the longest for 172 ms. During a long task the page ignores taps.

4 files block the first paint until they finish downloading. Deferring or inlining them could save about 50 ms.

About 15 KiB of CSS is downloaded but never applied on this page.

6 KiB could be saved by minifying JavaScript.

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

The page becomes fully interactive after 8.0 s. Good is under 3.8 s.

The first text or image appears after 2.9 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.8 s (Speed Index). Good is under 3.4 s.

Your largest element takes 2.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “We use cookies to personalise content and ads, to provide s…”. Most of its time is element render delay (1.3 s).

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

By the Sustainable Web Design model, a visit to your homepage emits about 0.24 g of CO₂e: 29.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

Your title is only 25 characters: “Nblocks is now The Bridge”. 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.

The homepage links to 12 pages on nblocks.dev and 2 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.

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

We fetched 8 pages linked from your homepage and read each the way a search engine does.

4 of 14 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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 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 120 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.

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

Opening the homepage sets 7 cookies (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.
