sailthru.com website review

8 third-party services load with your homepage (Google Tag Manager, Facebook and Digioh and others), adding 1.3 MB and 1.3 s of main-thread time.

Your mobile performance score is 74. Pages that score under 90 lose visitors before the first paint.

About 663 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 300 ms faster on a phone.

2 files block the first paint until they finish downloading. Deferring or inlining them could save about 700 ms.

Google Tag Manager costs a phone 628 ms of main-thread work and 537 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.

37 files are served with short cache lifetimes, so returning visitors download them again (534 KiB).

A phone's processor spends 3.8 s on main-thread work while loading, 2.2 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

17 long tasks block the main thread while loading, the longest for 194 ms. During a long task the page ignores taps.

Polyfills for old browsers add 83 KiB JavaScript that modern phones do not need.

About 20 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.

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

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.

The page becomes fully interactive after 21.1 s. Good is under 3.8 s.

Real visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

Real visitors wait 899 ms for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 563 ms in total while the page loads. Good is under 200 ms.

Your largest element takes 3.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Deliver Dynamic, Data-Driven Customer Journeys”.

Visually, the page fills in at 4.5 s (Speed Index). Good is under 3.4 s.

Your homepage downloads 2.5 MB in 179 requests on a phone: scripts 1.8 MB (55), images 548 KiB (52) and other files 77 KiB (58). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.71 g of CO₂e: 85.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Interactive controls must not be nested: 4 elements on the page fail this check, rated serious by axe-core.

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

The homepage links to only 1 page on your own site, so visitors and crawlers find few routes into the rest of it.

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

We fetched 1 page linked from your homepage and read each the way a search engine does.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

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

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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.

The homepage carries about 349 words of visible text.

Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 1 cookie (measured from a US location before any click).

Loading the homepage contacts 5 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
