tacitknowledge.com website review

89 files are served with short cache lifetimes, so returning visitors download them again (1.4 MB).

3 images could be 632 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 3.3 s faster on a phone.

44 files block the first paint until they finish downloading. Deferring or inlining them could save about 3.2 s.

Your mobile performance score is 55 (desktop: 87). Pages that score under 90 lose visitors before the first paint.

About 120 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

About 113 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

5 long tasks block the main thread while loading, the longest for 226 ms. During a long task the page ignores taps.

Polyfills for old browsers add 25 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

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

Desktop scores 87 but mobile only 55. A gap that wide usually means heavy scripts and images that hit phones hardest.

8 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

3 third-party services load with your homepage (flow8free.com, Google Fonts and Hubspot), adding 44 KiB and 0 ms of main-thread time.

4 KiB could be saved by minifying CSS.

Your largest element takes 10.7 s to render on a phone. Google's threshold for “good” is 2.5 s.

The first text or image appears after 5.5 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 10.7 s. Good is under 3.8 s.

Visually, the page fills in at 5.9 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 272 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.

dc_laptop.png weighs 635 KiB. On a phone connection a single image that size takes seconds.

1 image is downloaded at several times the size a phone draws it, for example dc_laptop.png at 1,574 px wide, shown at 291 px. Resized copies would save about 440 KiB.

1 image (635 KiB) is JPEG, PNG or GIF. The same pictures as WebP or AVIF are usually much smaller at the same quality, and every current browser shows them.

By the Sustainable Web Design model, a visit to your homepage emits about 0.41 g of CO₂e: 49.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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.

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

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

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

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 https://tacitknowledge.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.

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

We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

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 30 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.

The page uses urgency cues (a countdown or limited-time wording).

Before a visitor clicks anything, the page loads HubSpot (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 1 cookie (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 4 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
