provia.com website review

15 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.9 s.

The page has 4,392 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 4.0 s on main-thread work while loading, 1.7 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, trustindex.io and cdn-cookieyes.com and others), adding 3.2 MB and 892 ms of main-thread time.

Your mobile performance score is 62 (desktop: 81). Pages that score under 90 lose visitors before the first paint.

37 files are served with short cache lifetimes, so returning visitors download them again (899 KiB).

About 487 KiB of JavaScript is downloaded but never used on this page.

Google CDN costs a phone 408 ms of main-thread work and 741 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.

14 images could be 280 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Other Google APIs/SDKs costs a phone 28 ms of main-thread work and 1.9 MB 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.

About 77 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.

11 long tasks block the main thread while loading, the longest for 222 ms. During a long task the page ignores taps.

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

Polyfills for old browsers add 13 KiB JavaScript that modern phones do not need.

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 18.0 s. Good is under 3.8 s.

Your largest element takes 4.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “A home that shows ProVia doors, windows, siding, and stone”.

The first text or image appears after 3.0 s on a phone. Good is under 1.8 s.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 1.7 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

Real visitors wait 1.4 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 474 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 100 ms to 99 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 15.6 MB in 164 requests on a phone: media 10.7 MB (1), images 2.6 MB (65) and scripts 1.3 MB (55). Under 2 MB keeps phones on slow connections fast.

12 images are downloaded at several times the size a phone draws them, for example AABkmLf5vEwPmNOCIkyVrA3mGjT9HvvF5b2MWxqkcF7Pnxn_eH2VEXpvH6JO at 512 px wide, shown at 80 px. Resized copies would save about 605 KiB.

21 images (1.3 MB) are 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 4.43 g of CO₂e: 531.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Your title is 71 characters, so Google will cut it off around 60: “ProVia® Doors, Windows, Vinyl Siding, Manufactured Stone, Metal Roofing”.

The homepage links to 455 pages on provia.com and 12 external pages.

There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

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

We fetched 15 pages linked from your homepage (of 181 found) and read each the way a search engine does.

42 of 197 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

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

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 5,030 words of visible text.

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

Opening the homepage sets 6 cookies (measured from a US location before any click).

Loading the homepage contacts 22 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
