Speed

3 to fix85

  • Mobile performance score: 85

    85/100

    Your mobile performance score is 85. Pages that score under 90 lose visitors before the first paint.

  • Render-blocking requests

    950 ms

    34 files block the first paint until they finish downloading. Deferring or inlining them could save about 950 ms.

  • 2,658 HTML elements

    The page has 2,658 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Reduce unused CSS

    150 ms · 29 KiB

    About 29 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.

  • Improve image delivery

    17 KiB

    1 image could be 17 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Chained critical requests

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

  • Forced reflow

    Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

  • 1 third-party service on the page

    1 third-party service load with your homepage (Google Fonts), adding 50 KiB and 0 ms of main-thread time.

2 checks passed

  • Main-thread work: 0.5 s

    A phone's processor spends 0.5 s on main-thread work while loading, 80 ms of it running JavaScript. That is comfortably low.

  • Server response: 107 ms

    107 ms

    Your server sent the HTML in 107 ms, well inside Google's 600 ms guideline.

Core Web Vitals

8 to fix50

  • Fails Core Web Vitals for real visitors

    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-user TTFB: 1.8 s

    1.8 s

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

  • Speed Index: 7.6 s

    7.6 s

    Visually, the page fills in at 7.6 s (Speed Index). Good is under 3.4 s.

  • Real-user LCP: 3.2 s

    3.2 s

    Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Tap response (INP) got 31% slower for real visitors

    +31%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 99 ms to 136 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Real-user FCP: 2.2 s

    2.2 s

    Real visitors see the first content after 2.2 s (75th percentile). Good is under 1.8 s.

  • Largest Contentful Paint: 3.1 s

    3.1 s

    Your largest element takes 3.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “AI-Powered Security. Expert Human Monitoring.”. Most of its time is element render delay (5.6 s).

  • First Contentful Paint: 2.0 s

    2.0 s

    The first text or image appears after 2.0 s on a phone. Good is under 1.8 s.

  • Largest content (LCP) held steady for real visitors

    +6%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.0 s to 3.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

4 checks passed

  • Real-user CLS: 0.02

    0.02

    For real visitors the layout shifts by 0.02 (75th percentile). Good is under 0.1.

  • Time to Interactive: 3.1 s

    3.1 s

    The page is fully interactive after 3.1 s.

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

  • Total Blocking Time: 0 ms

    0 ms

    Scripts block the page for only 0 ms while loading. Good is under 200 ms.

Images and page weight

100

  • About 0.1 g of CO₂ per visit

    0.11 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.11 g of CO₂e: 13.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

4 checks passed

  • Page weight: 394 KiB in 46 requests

    394 KiB

    Your homepage downloads 394 KiB in 46 requests on a phone: images 167 KiB (7), stylesheets 106 KiB (35) and fonts 65 KiB (2). That is a lean page.

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

2 to fixGoogle 9896

  • 30 images without alt text

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

  • Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (2 elements)

    Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 2 elements on the page fail this check, rated moderate by axe-core.

  • Headings skip levels

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

1 checks passed

  • 39 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 41 WCAG 2.2 A/AA and best-practice rules on the phone render: 39 passed and 2 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

3 to fixGoogle 10084

  • Title is long (68 characters)

    Your title is 68 characters, so Google will cut it off around 60: “AI-Powered Security with Expert Human Monitoring | Interface Systems”.

  • Meta description is long (192 characters)

    Your meta description is 192 characters; Google truncates after about 160, so the end of your pitch is cut.

  • Structured data has 3 problems

    Structured data found (FAQPage, Organization, Service and WebPage) but with 3 problems, for example “Service: no offers (price) block”.

  • 307 internal links, 16 external

    The homepage links to 307 pages on interfacesystems.com and 16 external pages.

5 checks passed

  • One H1 headline

    Your main headline reads: “AI-Powered Security. Expert Human Monitoring.”.

  • Canonical URL set

    The canonical URL is https://interfacesystems.com/.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://www.interfacesystems.com/sitemap_index.xml.

AI search readiness

100
4 checks passed

  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 6 of 6 facts

    Your Organization JSON-LD gives name, url, logo, sameAs (social profiles), description and contact details.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,913 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes /llms.txt (5 KiB, 15 links), a plain-text guide to the site for AI tools.

Other pages

100

  • 4 pages slow to respond

    /managed-network-voice-services, /remote-video-monitoring/virtual-security-guard, /remote-video-monitoring/video-verified-alarm and /managed-alarms-access-control/managed-access-control took over 3 s to send their HTML from our server.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 61 found) and read each the way a search engine does.

7 checks passed

1 checks passed

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix94

  • Local business without LocalBusiness data

    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.

  • No opening hours

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

  • No map or directions link

    There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

  • About 274 words of copy

    The homepage carries about 274 words of visible text.

8 checks passed

  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Get a Free Consultation”.

    Social proof on the homepage: 42 testimonial or review blocks and 9 customer or partner logos.

  • Analytics in place

    Analytics detected: Google Tag Manager.

  • Direct contact links

    Your phone number is on the homepage as a tap-to-call link.

  • Risk reducer mentioned

Privacy and tracking

  • 3 cookies set on arrival

    3

    Opening the homepage sets 3 cookies (measured from a US location before any click).

  • No consent tool detected

    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.

  • 2 other companies contacted

    Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed

  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).

Security, domain, email and software versions

The security, domain and email checks, software and plugin versions, and any app with a known security problem are visible only to people at interfacesystems.com, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
