telephonics.com website review

45 files are served with short cache lifetimes, so returning visitors download them again (21.7 MB).

11 images could be 17.8 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 84.7 s faster on a phone.

About 827 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 4.0 s faster on a phone.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 4.3 s.

About 542 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 2.7 s faster on a phone.

Your mobile performance score is 56 (desktop: 53). Pages that score under 90 lose visitors before the first paint.

143 KiB could be saved by minifying JavaScript.

FontAwesome CDN costs a phone 65 ms of main-thread work and 422 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 68 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

3 third-party services load with your homepage (FontAwesome CDN, Plausible and Google Fonts), adding 468 KiB and 70 ms of main-thread time.

2 long tasks block the main thread while loading, the longest for 97 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.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

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.

Real visitors wait 4.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

For real visitors the layout shifts by 0.39 (75th percentile). Good is under 0.1.

Real visitors see the first content after 3.1 s (75th percentile). Good is under 1.8 s.

Your largest element takes 106.9 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 20.1 s (Speed Index). Good is under 3.4 s.

The page becomes fully interactive after 106.9 s. Good is under 3.8 s.

The first text or image appears after 5.4 s on a phone. Good is under 1.8 s.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

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

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 94 ms to 93 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.4 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 22.3 MB in 52 requests on a phone: images 20.0 MB (34), scripts 1.6 MB (9) and stylesheets 600 KiB (6). Under 2 MB keeps phones on slow connections fast.

2 images (188 KiB) 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.

1 image further down the page (20 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 6.32 g of CO₂e: 758.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Certain ARIA roles must contain particular children: 1 element on the page fails this check, rated critical by axe-core.

Links must have discernible text: 8 elements on the page fail this check, rated serious by axe-core.

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

1 tap target is too small or too close together to hit reliably with a finger.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

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

No XML sitemap at https://www.ttm.com/sitemap.xml, so Google discovers your pages only by following links.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

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

The homepage links to 223 pages on telephonics.com and 85 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.ttm.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.

https://www.ttm.com/en/about-ttm/latest-updates and https://www.ttm.com/en/about-ttm/global-locations have no meta description, so Google writes the search snippet from whatever text it finds.

https://www.ttm.com/en/about-ttm/who-we-are/life-at-ttm, https://www.ttm.com/en/about-ttm/corporate-structure, https://www.ttm.com/en/about-ttm/latest-updates and https://www.ttm.com/en/about-ttm/achievements took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 88 found) and read each the way a search engine does.

23 of 41 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

3 images are served at too low a resolution for sharp phone screens.

Large scripts ship without source maps.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 402 words of visible text.

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