diversifiedelectronics.com website review

About 1.6 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 8.4 s faster on a phone.

60 files block the first paint until they finish downloading. Deferring or inlining them could save about 5.4 s.

25 files are served with short cache lifetimes, so returning visitors download them again (537 KiB).

About 209 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.3 s faster on a phone.

2 images could be 210 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 1.0 s faster on a phone.

Your mobile performance score is 49 (desktop: 42). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google CDN, Google Tag Manager and Facebook and others), adding 2.7 MB and 1.2 s of main-thread time.

Google CDN costs a phone 621 ms of main-thread work and 1.8 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.

A phone's processor spends 3.8 s on main-thread work while loading, 2.1 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Google Tag Manager costs a phone 293 ms of main-thread work and 521 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 2,447 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

13 long tasks block the main thread while loading, the longest for 126 ms. During a long task the page ignores taps.

Polyfills for old browsers add 12 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.

The first text or image appears after 13.7 s on a phone. Good is under 1.8 s.

Your largest element takes 30.3 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

Visually, the page fills in at 17.2 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 30.7 s. Good is under 3.8 s.

Scripts block taps and scrolling for 299 ms in total while the page loads. Good is under 200 ms.

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

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.

Your homepage downloads 6.9 MB in 233 requests on a phone: scripts 2.9 MB (66), images 2.2 MB (43) and other files 734 KiB (46). Under 2 MB keeps phones on slow connections fast.

1 image (32 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 (61 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 1.95 g of CO₂e: 233.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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.

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

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

Headings skip levels (h1 → h3, h2 → h4 and h2 → h4), which makes the page harder to scan with a screen reader.

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

There are 2 <h1> headlines (“IFC 510 In Building Solutions Next Generation Com…” and “IFC 510 In Building Solutions Next Generation Com…”). One clear main headline is easier for people and search engines.

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

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

The homepage links to 216 pages on diversifiedelectronics.com and 20 external pages.

Your Organization JSON-LD is missing logo, 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.

We fetched 15 pages linked from your homepage (of 51 found) and read each the way a search engine does.

1 error was logged to the browser console while the page loaded, for example “reCAPTCHA has already been rendered in this element”.

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

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

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

diversifiedelectronics.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.

diversifiedelectronics.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 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.

The homepage shows no opening hours. If customers visit or call, show when.

There is no form on the homepage, so every lead has to click through to another page first.

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 1,132 words of visible text.

diversifiedelectronics.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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, LinkedIn Insight and Meta Pixel and 1 more (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 9 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 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
