alliedvalveinc.com website review

55 files are served with short cache lifetimes, so returning visitors download them again (1.3 MB).

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.4 s.

8 third-party services load with your homepage (Google Tag Manager, YouTube and Facebook and others), adding 1.9 MB and 1.2 s of main-thread time.

About 930 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 450 ms faster on a phone.

Your mobile performance score is 54 (desktop: 87). Pages that score under 90 lose visitors before the first paint.

13 images could be 698 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.

YouTube costs a phone 452 ms of main-thread work and 999 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.

Google Tag Manager costs a phone 466 ms of main-thread work and 668 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.

A phone's processor spends 2.5 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

About 145 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.

13 long tasks block the main thread while loading, the longest for 162 ms. During a long task the page ignores taps.

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

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

Desktop scores 87 but mobile only 54. A gap that wide usually means heavy scripts and images that hit phones hardest.

7 KiB could be saved by minifying CSS.

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 23.4 s. Good is under 3.8 s.

Your largest element takes 6.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Allied Valve: Valve and Actuation Sales, Service, and Repai…”.

The first text or image appears after 3.8 s on a phone. Good is under 1.8 s.

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

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' largest content (lcp) went from 2.2 s to 3.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors see the first content after 2.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.8 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 370 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-10, real Chrome visitors' tap response (inp) went from 97 ms to 83 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 161 requests on a phone: scripts 1.9 MB (42), images 981 KiB (48) and HTML 170 KiB (3). Under 2 MB keeps phones on slow connections fast.

1 image (84 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.

2 images further down the page (40 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 0.96 g of CO₂e: 114.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

21 links inside paragraphs rely on colour alone to stand out.

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

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

All page content should be contained by landmarks: 4 elements on the page fail 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.

Headings skip levels (h2 → h4, h3 → h5 and h2 → h4), which makes the page harder to scan with a screen reader.

The homepage links to 166 pages on alliedvalveinc.com and 5 external pages.

There is no /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.

/products/biffi has no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 60 found) and read each the way a search engine does.

16 of 30 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

3 errors were logged to the browser console while the page loaded, for example “Manifest: Line: 1, column: 1, Syntax error.”.

6 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

Chrome logged issues while loading the page (“Cookie”).

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

1 link go through two or more redirects, for example https://myaviportal.com/.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

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

alliedvalveinc.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

alliedvalveinc.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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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.

The homepage carries about 406 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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and The Trade Desk (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 8 cookies, 1 of them by other companies (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 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
