tessian.com website review

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

About 195 KiB of JavaScript is downloaded but never used on this page.

1 long task block the main thread while loading, the longest for 101 ms. During a long task the page ignores taps.

5 third-party services load with your homepage (Google/Doubleclick Ads, Marketo and geoip-js.com and others), adding 38 KiB and 27 ms of main-thread time.

Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

4 files are served with short cache lifetimes, so returning visitors download them again (5 KiB).

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

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Real visitors wait 4.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 4.5 s (75th percentile). Good is under 1.8 s.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.8 s to 4.6 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

The page becomes fully interactive after 4.5 s. Good is under 3.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 183 ms to 169 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

2 images are downloaded at several times the size a phone draws them, for example AdaptiveEmailSecurity_RealTimeCoaching.png.webp at 2,078 px wide, shown at 358 px. Resized copies would save about 113 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.14 g of CO₂e: 17.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Links must have discernible text: 4 elements on the page fail this check, rated serious by axe-core.

68 tap targets are too small or too close together to hit reliably with a finger.

Headings skip levels (h1 → h4), which makes the page harder to scan with a screen reader.

The homepage links to 124 pages on tessian.com and 17 external pages.

There is no https://www.proofpoint.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.

Your homepage links to 2 pages by a URL that isn't their canonical one, for example https://www.proofpoint.com/us/products/email-security-and-protection/secure-email-relay, whose canonical is https://www.proofpoint.com/us/products/secure-email-relay. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 88 found) and read each the way a search engine does.

3 of 10 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

Large scripts ship without source maps.

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.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

The homepage has only about 202 words of visible text; thin pages give Google and first-time buyers little to go on.

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

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.

Before a visitor clicks anything, the page loads Google Ads (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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
