jacobslevy.com website review

24 files are served with short cache lifetimes, so returning visitors download them again (3.0 MB).

About 314 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

Your mobile performance score is 59 (desktop: 80). Pages that score under 90 lose visitors before the first paint.

5 images could be 331 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Google CDN costs a phone 151 ms of main-thread work and 347 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.

7 third-party services load with your homepage (Google CDN, Google Tag Manager and cloudfront.net and others), adding 814 KiB and 424 ms of main-thread time.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 200 ms.

2 long tasks block the main thread while loading, the longest for 180 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

The HTML itself could arrive sooner: redirects, a slow server response or missing compression delay everything after it.

About 13 KiB of CSS is downloaded but never applied on this page.

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

2 KiB could be saved by minifying JavaScript.

Your largest element takes 16.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “PIONEERING INVESTMENT RESEARCH Bruce Jacobs and Ken Levy pi…”.

The page becomes fully interactive after 16.3 s. Good is under 3.8 s.

Visually, the page fills in at 7.2 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.5 s on a phone. Good is under 1.8 s.

2 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.

Your homepage downloads 4.0 MB in 54 requests on a phone: images 3.2 MB (27), scripts 599 KiB (12) and fonts 211 KiB (8). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.13 g of CO₂e: 136.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.

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

All page content should be contained by landmarks: 22 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.

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

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

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

1 visible link has no text or label, so screen readers cannot say where it goes.

The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.

No meta description, so Google writes its own snippet from whatever text it finds.

There is no <h1>, so neither visitors nor Google get a clear main headline.

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

No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

No XML sitemap at https://jlem.com/sitemap.xml, so Google discovers your pages only by following links.

There is no robots.txt at jlem.com/robots.txt, the first file search crawlers ask for.

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

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 28 pages on jacobslevy.com and 4 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://jlem.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://jlem.com/who-we-are, https://jlem.com/what-we-do, https://jlem.com/research and https://jlem.com/contact-us have no meta description, so Google writes the search snippet from whatever text it finds.

https://jlem.com/contact-us has 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 6 pages linked from your homepage and read each the way a search engine does.

3 errors were logged to the browser console while the page loaded, for example “Failed to load resource: the server responded with a status of 404 (Not Found)”.

1 image is served at too low a resolution for sharp phone screens.

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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

The homepage shows no opening hours. If customers visit or call, show when.

There is no form on the homepage, so every lead has to click through to another page first.

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 527 words of visible text.

Before a visitor clicks anything, the page loads 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 7 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 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
