agentboost.com website review

About 244 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

9 images could be 1.1 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

Your mobile performance score is 67 (desktop: 92). Pages that score under 90 lose visitors before the first paint.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 750 ms.

About 28 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 150 ms faster on a phone.

1 long task block the main thread while loading, the longest for 90 ms. During a long task the page ignores taps.

Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need.

Desktop scores 92 but mobile only 67. A gap that wide usually means heavy scripts and images that hit phones hardest.

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

Visually, the page fills in at 7.8 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 9.0 s. Good is under 3.8 s.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.2 s to 2.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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.

hero-hangar.webp weighs 985 KiB. On a phone connection a single image that size takes seconds.

4 images are downloaded at several times the size a phone draws them, for example hero-hangar.webp at 2,560 px wide, shown at 402 px. Resized copies would save about 1.0 MB.

Your homepage downloads 2.2 MB in 42 requests on a phone: images 1.5 MB (12), scripts 369 KiB (11) and fonts 204 KiB (10). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 0.63 g of CO₂e: 75.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Elements with visible text labels do not have matching accessible names. (1 element).

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

The homepage links to 46 pages on agentboost.com and 3 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User) read the homepage but closes other sections to them, so answers about those pages can't cite you.

We fetched 15 pages linked from your homepage (of 22 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

agentboost.com's DNS answers are not signed. DNSSEC stops attackers forging them to send visitors or email elsewhere; most registrars switch it on in a click, though most sites still run without it.

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.

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

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 558 words of visible text.

Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

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.
