onebright.com website review

About 544 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.8 s faster on a phone.

Your mobile performance score is 68. Pages that score under 90 lose visitors before the first paint.

1 image could be 156 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

4 files are served with short cache lifetimes, so returning visitors download them again (51 KiB).

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 500 ms.

About 92 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.

Google Tag Manager costs a phone 300 ms of main-thread work and 524 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.

The page has 1,533 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, Cookiebot and jQuery CDN and others), adding 803 KiB and 497 ms of main-thread time.

5 long tasks block the main thread while loading, the longest for 126 ms. During a long task the page ignores taps.

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 largest element takes 10.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “CBT London”.

The page becomes fully interactive after 10.9 s. Good is under 3.8 s.

The first text or image appears after 2.7 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.2 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 82 ms to 87 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.4 s to 1.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

By the Sustainable Web Design model, a visit to your homepage emits about 0.51 g of CO₂e: 61.4 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.

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

1 element hidden from screen readers can still receive keyboard focus.

Your meta description is 161 characters; Google truncates after about 160, so the end of your pitch is cut.

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

17 links have no real href, so search engines can't follow them.

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

The homepage links to 191 pages on onebright.com and 5 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://onebright.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.

https://onebright.com/join-our-team, https://onebright.com/who-we-help/adults/therapy-for-adults, https://onebright.com/who-we-help/adults/adhd-for-adults, https://onebright.com/who-we-help/adults/autism-for-adults, https://onebright.com/who-we-help/children/adhd-for-children and https://onebright.com/who-we-help/children/autism-for-children have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 54 found) and read each the way a search engine does.

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 876 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager and HubSpot (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 6 cookies (measured from a US location before any click).

Loading the homepage contacts 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
