generalinsulation.com website review

About 1.4 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 9.2 s faster on a phone.

76 files are served with short cache lifetimes, so returning visitors download them again (3.5 MB).

26 images could be 2.8 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.3 s faster on a phone.

35 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.2 s.

Your mobile performance score is 48. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 4.4 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Facebook and others), adding 2.8 MB and 1.2 s of main-thread time.

About 199 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 900 ms faster on a phone.

Google CDN costs a phone 513 ms of main-thread work and 1.5 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.

Google Tag Manager costs a phone 196 ms of main-thread work and 420 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.

The page has 1,876 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Google Maps costs a phone 120 ms of main-thread work and 393 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.

Polyfills for old browsers add 33 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 250 ms faster on a phone.

17 long tasks block the main thread while loading, the longest for 142 ms. During a long task the page ignores taps.

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.

4 KiB could be saved by minifying CSS.

3 KiB could be saved by minifying JavaScript.

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 first text or image appears after 11.3 s on a phone. Good is under 1.8 s.

Your largest element takes 53.9 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Image”.

Visually, the page fills in at 21.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 55.9 s. Good is under 3.8 s.

Real visitors wait 2.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Scripts block taps and scrolling for 335 ms in total while the page loads. Good is under 200 ms.

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 79 ms to 77 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.6 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 18.6 MB in 244 requests on a phone: images 11.1 MB (109), scripts 3.2 MB (67) and media 2.5 MB (1). Under 2 MB keeps phones on slow connections fast.

3 images weigh 1.7 MB together. On a phone connection a single image that size takes seconds.

37 images (6.7 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.

5 images further down the page (1.6 MB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

4 images are downloaded at several times the size a phone draws them, for example 872374192_18569428888073486_6160562814288210057_n.jpg at 1,080 px wide, shown at 342 px. Resized copies would save about 145 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 5.28 g of CO₂e: 633.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

11 images have no alt text, which hurts accessibility and image search.

8 visible links have no text or label, so screen readers cannot say where they go.

2 form fields have no label, so screen readers announce an empty box and autofill guesses.

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

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

8 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

1 link has no real href, so search engines can't follow it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 263 pages on generalinsulation.com and 17 external pages.

Your Organization JSON-LD is missing sameAs (social profiles), description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

/product-category/mechanical-insulation-products/insulation-types/fiberglass, /product-category/mechanical-insulation-products/insulation-types/fitting-canvas, /product-category/mechanical-insulation-products/insulation-types/foamglas-insulation, /product-category/mechanical-insulation-products/industrial-insulation/mineral-wool-insulation, /product-category/mechanical-insulation-products/insulation-types/rubber-insulation and /product-category/mechanical-insulation-products/insulation-types/aerogel-commercial-insulation and 1 other all use the title “Insulation Products - General Insulation Company”. Search engines can't tell which page to show for a search, so each competes with the others.

/commitment-to-sustainability, /customer-feedback, /request-a-quote, /gic-credit-application, /product-categories and /commercial-insulation and 1 other have no meta description, so Google writes the search snippet from whatever text it finds.

/product-category/mechanical-insulation-products/insulation-types/fiberglass, /product-category/mechanical-insulation-products/insulation-types/fitting-canvas, /product-category/mechanical-insulation-products/insulation-types/foamglas-insulation, /product-category/mechanical-insulation-products/industrial-insulation/mineral-wool-insulation, /product-category/mechanical-insulation-products/insulation-types/rubber-insulation and /product-category/mechanical-insulation-products/insulation-types/aerogel-commercial-insulation and 1 other use the same meta description. A description written for each page earns more clicks.

Your homepage links to 7 pages by a URL that isn't their canonical one, for example /product-category/mechanical-insulation-products/insulation-types/fiberglass, whose canonical is /products. 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 127 found) and read each the way a search engine does.

2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

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

Requests the geolocation permission on page load.

1 link to other sites is dead, for example https://buildzit.com/product-list (404).

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

generalinsulation.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.

generalinsulation.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.

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

The homepage carries about 633 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 Analytics, Google Tag Manager, HubSpot, LinkedIn Insight and Meta Pixel (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 14 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 24 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
