Speed

9 to fix50
  • Reduce unused JavaScript

    3.3 s · 997 KiB

    About 997 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.3 s faster on a phone.

  • Use efficient cache lifetimes

    1.8 s · 661 KiB

    33 files are served with short cache lifetimes, so returning visitors download them again (661 KiB).

  • Render-blocking requests

    1.1 s

    7 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Google Tag Manager, Google CDN and 8x8.com and others), adding 2.1 MB and 1.4 s of main-thread time.

  • Mobile performance score: 50

    50/100

    Your mobile performance score is 50. Pages that score under 90 lose visitors before the first paint.

  • Google Tag Manager adds 797 ms

    797 ms

    Google Tag Manager costs a phone 797 ms of main-thread work and 971 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.

  • Google CDN adds 390 ms

    390 ms

    Google CDN costs a phone 390 ms of main-thread work and 741 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.

  • Main-thread work: 3.0 s

    A phone's processor spends 3.0 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 2,002 HTML elements

    The page has 2,002 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Improve image delivery

    150 ms · 191 KiB

    4 images could be 191 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

  • Reduce unused CSS

    150 ms · 72 KiB

    About 72 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.

  • 13 long tasks on the main thread

    13 long tasks block the main thread while loading, the longest for 206 ms. During a long task the page ignores taps.

  • Minify JavaScript

    27 KiB

    27 KiB could be saved by minifying JavaScript.

  • 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.

1 checks passed
  • Server response: 128 ms

    128 ms

    Your server sent the HTML in 128 ms, well inside Google's 600 ms guideline.

Core Web Vitals

6 to fix100
  • Largest Contentful Paint: 9.6 s

    9.6 s

    Your largest element takes 9.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

  • Time to Interactive: 18.7 s

    18.7 s

    The page becomes fully interactive after 18.7 s. Good is under 3.8 s.

  • Speed Index: 7.5 s

    7.5 s

    Visually, the page fills in at 7.5 s (Speed Index). Good is under 3.4 s.

  • Total Blocking Time: 637 ms

    637 ms

    Scripts block taps and scrolling for 637 ms in total while the page loads. Good is under 200 ms.

  • 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.

  • 1 image without width and height

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

  • Tap response (INP) got 15% slower for real visitors

    +15%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 136 ms to 158 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    +8%

    Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.8 s to 2.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

7 checks passed
  • Passes Core Web Vitals for real visitors

    Real Chrome users on phones pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)).

  • Real-user LCP: 1.4 s

    1.4 s

    Real visitors wait 1.4 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 120 ms

    120 ms

  • Real-user FCP: 1.1 s

    1.1 s

  • Real-user TTFB: 512 ms

    512 ms

    Real visitors wait 512 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • Cumulative Layout Shift: 0

    0

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

Images and page weight

2 to fix83
  • Page weight: 3.5 MB in 87 requests

    3.5 MB

    Your homepage downloads 3.5 MB in 87 requests on a phone: scripts 2.2 MB (37), images 610 KiB (16) and other files 363 KiB (16). Under 2 MB keeps phones on slow connections fast.

  • An image on the first screen is lazy-loaded

    WEB-HERO-2000x1000_S2627_00_Season_Final-450x225.jpg is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

  • 3 images in older formats

    3 images (171 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 below the first screen load straight away

    1 image further down the page (60 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

  • About 1.0 g of CO₂ per visit

    0.99 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.99 g of CO₂e: 118.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed
  • Images are sized for phones

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

Accessibility

6 to fixGoogle 9493
  • 14 text elements with low contrast

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

  • Elements must only use permitted ARIA attributes (3 elements)

    Elements must only use permitted ARIA attributes: 3 elements on the page fail this check, rated serious by axe-core.

  • All page content should be contained by landmarks (2 elements)

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

  • 6 links without text

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

  • 1 form field without a label

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

  • Headings should not be empty (1 element)

    Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

2 checks passed
  • Every image has alt text

    All 13 images in the HTML carry an alt attribute.

  • 50 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 54 WCAG 2.2 A/AA and best-practice rules on the phone render: 50 passed and 4 failed. 5 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

2 to fixGoogle 10091
  • No robots.txt

    There is no robots.txt at eno.org/robots.txt, the first file search crawlers ask for.

  • One H1 headline

    Your <h1> is empty.

  • 50 internal links, 9 external

    The homepage links to 50 pages on eno.org and 9 external pages.

6 checks passed
  • Meta description: 154 characters

    Your meta description is 154 characters: “English National Opera (ENO) is the national opera company dedicated to one simple aim: creating extraordinary encounte…”.

  • Title: 35 characters

    Your title is a healthy 35 characters: “Home | English National Opera | ENO”.

  • Canonical URL set

    The canonical URL is https://www.eno.org/.

  • Structured data in place

    Structured data found: BreadcrumbList, ImageObject, WebPage and WebSite.

  • Open Graph tags complete

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

  • XML sitemap found

    Your XML sitemap is reachable at https://www.eno.org/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

    There is no robots.txt, so nothing stops the crawlers behind ChatGPT search, Claude and Perplexity from reading the site and cite it in answers.

  • Text is in the HTML

    Your server sends the page's text in the HTML (480 words), so crawlers that don't run JavaScript still read it.

Other pages

1 to fix95
  • 3 pages without a meta description

    /support-us, /support-us/donate-now and /engage/creative-health-and-wellbeing have no meta description, so Google writes the search snippet from whatever text it finds.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 31 found) and read each the way a search engine does.

6 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Titles are unique

    Every page we checked has its own title.

  • Every page has an H1

    Each page we checked has a main headline.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 15 pages that loaded have a <title>.

Best practices

1 to fixGoogle 7797
  • Deprecated browser APIs

    The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

  • Missing source maps

    Large scripts ship without source maps.

3 checks passed
  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Tap targets are thumb-sized

    19 of 20 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Security and trust

100
  • No security.txt

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

8 checks passed
  • Served over HTTPS

    The homepage is served over HTTPS (eno.org).

  • Valid certificate (36 days left)

    The certificate from Google Trust Services · WE1 verifies for eno.org and is valid for another 36 days.

  • Protected from clickjacking

    X-Frame-Options or a frame-ancestors policy stops other sites framing yours.

  • Content-Security-Policy set

    A Content-Security-Policy is set, the main browser-side defence against injected scripts.

  • HSTS enabled

    Strict-Transport-Security is set, so browsers always use https.

  • http:// redirects to https

    http://eno.org redirects to the secure version.

  • HTTP/2

    The server speaks HTTP/2, so browsers load many files over one connection.

  • All 41 links work

    All 41 links checked from your homepage (34 internal, 7 external) answered without errors.

Domain and trust

  • No CAA record

    eno.org 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.

  • DNSSEC is off

    eno.org'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.

2 checks passed
  • Domain is 30 years old

    30 years

    eno.org was registered in Apr 1996 through Gandi SAS. An established domain carries more trust with email providers and search engines.

  • Registered until Apr 2027

    eno.org is registered until Apr 2027.

Content and conversion

3 to fix71
  • No call to action on the first screen

    On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

  • Thin social proof

    Social proof on the homepage: 22 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

  • 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.

  • About 351 words of copy

    The homepage carries about 351 words of visible text.

4 checks passed
  • 5 calls to action

    The homepage has 5 calls to action, for example “Book for Angel’s Bone”, “Book for Tosca” and “Book for La traviata”.

  • 3 short forms

    3 short forms (1 field at most) are right on the homepage.

  • Analytics in place

    Analytics detected: Google Tag Manager.

  • Risk reducer mentioned

    A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.

Email authentication

85
  • Email authentication score: 85/100

    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.

3 checks passed
  • DMARC policy: quarantine

    DMARC tells receivers to quarantine mail that fails authentication, and sends you reports.

  • SPF in place (~all)

    An SPF record lists your sending servers and marks other mail as suspicious (~all): “v=spf1 include:spf2.eno.org include:_spf.elasticemail.com include:_spf.salesforce.com ~all”.

  • DKIM signing found

    A DKIM key is published (selector “selector1”, “selector2” and “s1”), so receivers can verify mail really came from you.

Privacy and tracking

  • 3 trackers load before any consent

    3

    Before a visitor clicks anything, the page loads Google Ads, Google Analytics and Google Tag Manager (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

  • 1 cookie set on arrival

    1

    Opening the homepage sets 1 cookie, 1 of them by other companies (measured from a US location before any click).

  • 15 other companies contacted
