verticalized.co website review

About 652 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.8 s faster on a phone.

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

Your mobile performance score is 55. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (substackcdn.com, Google Tag Manager and datadoghq-browser-agent.com and others), adding 2.7 MB and 660 ms of main-thread time.

substackcdn.com costs a phone 482 ms of main-thread work and 2.4 MB 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 81 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

4 files are served with short cache lifetimes, so returning visitors download them again (49 KiB).

7 long tasks block the main thread while loading, the longest for 252 ms. During a long task the page ignores taps.

A phone's processor spends 2.1 s on main-thread work while loading, 989 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 29 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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

The page becomes fully interactive after 18.3 s. Good is under 3.8 s.

Visually, the page fills in at 7.5 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.1 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 313 ms in total while the page loads. Good is under 200 ms.

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.

Your homepage downloads 2.8 MB in 274 requests on a phone: scripts 2.4 MB (218), stylesheets 265 KiB (38) and images 99 KiB (5). Under 2 MB keeps phones on slow connections fast.

https://substack-post-media.s3.amazonaws.com/public/images/5 is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 0.79 g of CO₂e: 95.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 frame has no title, so screen-reader users cannot tell what it contains.

All page content should be contained by landmarks: 5 elements on the page fail this check, rated moderate by axe-core.

The viewport tag blocks pinch-zoom, which low-vision visitors rely on.

Your title is 75 characters, so Google will cut it off around 60: “Verticalized: The Newsletter for Industry Disruption | Eli Dukes | Substack”.

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

Your meta description is 168 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

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://verticalized.co/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.

2 errors were logged to the browser console while the page loaded, for example “When fetching the accounts endpoint, a 401 HTTP response code was received.”.

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 42 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 Ads 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 16 cookies, 5 of them by other companies (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.
