Speed

10 to fix63
  • Render-blocking requests

    1.5 s

    16 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.5 s.

  • Main-thread work: 6.0 s

    A phone's processor spends 6.0 s on main-thread work while loading, 2.9 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Hotjar and hubspotusercontent-na1.net and others), adding 1.3 MB and 1.9 s of main-thread time.

  • Use efficient cache lifetimes

    1,003 KiB

    68 files are served with short cache lifetimes, so returning visitors download them again (1,003 KiB).

  • Mobile performance score: 63

    63/100

    Your mobile performance score is 63. Pages that score under 90 lose visitors before the first paint.

  • Google Tag Manager adds 892 ms

    892 ms

    Google Tag Manager costs a phone 892 ms of main-thread work and 829 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.

  • Reduce unused JavaScript

    573 KiB

    About 573 KiB of JavaScript is downloaded but never used on this page.

  • Hotjar adds 430 ms

    430 ms

    Hotjar costs a phone 430 ms of main-thread work and 274 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.

  • 20 long tasks on the main thread

    20 long tasks block the main thread while loading, the longest for 371 ms. During a long task the page ignores taps.

  • 1,935 HTML elements

    The page has 1,935 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Improve image delivery

    149 KiB

    2 images could be 149 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • Font display

    100 ms

    Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

  • Legacy JavaScript

    14 KiB

    Polyfills for old browsers add 14 KiB JavaScript that modern phones do not need.

  • 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 checks passed
  • Server response: 13 ms

    13 ms

    Your server sent the HTML in 13 ms, well inside Google's 600 ms guideline.

Core Web Vitals

7 to fix100
  • 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 visitors see the first content after 2.0 s (75th percentile). Good is under 1.8 s.

  • 79 images without width and height

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

  • First Contentful Paint: 2.5 s

    2.5 s

    The first text or image appears after 2.5 s on a phone. Good is under 1.8 s.

  • Tap response (INP) held steady for real visitors

    +7%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 116 ms to 131 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

    +13%

    Over the last 25 four-week periods to 2026-10-31, 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).

6 checks passed

  • Largest Contentful Paint: 2.5 s

    2.5 s

  • Cumulative Layout Shift: 0

    0

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

Images and page weight

1 to fix70
  • Page weight: 9.6 MB in 138 requests

    9.6 MB

    Your homepage downloads 9.6 MB in 138 requests on a phone: media 7.3 MB (1), scripts 1.4 MB (36) and fonts 522 KiB (8). Under 2 MB keeps phones on slow connections fast.

  • About 2.7 g of CO₂ per visit

    2.72 g

    By the Sustainable Web Design model, a visit to your homepage emits about 2.72 g of CO₂e: 326.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed
  • 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 9597
  • 2 buttons without a name

    2 buttons have no accessible name, so screen readers announce just “button”.

  • All page content should be contained by landmarks (1 element)

    All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

2 checks passed
  • Every image has alt text

    All 157 images in the HTML carry an alt attribute.

  • 43 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 45 WCAG 2.2 A/AA and best-practice rules on the phone render: 43 passed and 2 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

Google 100100
  • 126 internal links, 33 external

    The homepage links to 126 pages on constructor.com and 33 external pages.

8 checks passed
  • Meta description: 140 characters

  • XML sitemap found

    Your XML sitemap is reachable at https://constructor.com/sitemap.xml.

AI search readiness

1 to fix88
  • No Organization structured data

    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.

  • No llms.txt

    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.

2 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.

  • Text is in the HTML

    Your server sends the page's text in the HTML (2,644 words), so crawlers that don't run JavaScript still read it.

100

Security and trust

100

  • All 56 links work

    All 56 links checked from your homepage (39 internal, 17 external) answered without errors.

Domain and trust

  • No CAA record

    constructor.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.

3 checks passed
  • Domain is 31 years old

    31 years

    constructor.com was registered in Jul 1995 through Amazon Registrar, Inc.. An established domain carries more trust with email providers and search engines.

  • Registered until Jul 2028

    constructor.com is registered until Jul 2028.

Content and conversion

1 to fix90
  • No direct contact details

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

  • No form on the homepage

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

  • No risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

  • Analytics in place

    Analytics detected: Google Tag Manager and Google Analytics.

Email authentication

1 to fix70
  • DMARC is monitor-only (p=none)

    DMARC is set to p=none, so mail pretending to be constructor.com is still delivered. Reports are on, so moving to quarantine is the next step.

  • Email authentication score: 70/100

    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.

2 checks passed
  • SPF in place (~all)

    An SPF record lists your sending servers and marks other mail as suspicious (~all): “v=spf1 include:_spf.google.com include:sendgrid.net include:4139600.spf02.hubspotemail.net ~all”.

  • DKIM signing found

    A DKIM key is published (selector “google”), so receivers can verify mail really came from you.

Privacy and tracking

  • 7 trackers load before any consent

    7

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Hotjar and HubSpot and 2 mores (measured from a US location before any click).
