Speed

2 to fix90

  • Render-blocking requests

    400 ms

    2 files block the first paint until they finish downloading. Deferring or inlining them could save about 400 ms.

  • Reduce unused JavaScript

    346 KiB

    About 346 KiB of JavaScript is downloaded but never used on this page.

  • Use efficient cache lifetimes

    200 ms · 123 KiB

    12 files are served with short cache lifetimes, so returning visitors download them again (123 KiB).

  • 5 long tasks on the main thread

    5 long tasks block the main thread while loading, the longest for 100 ms. During a long task the page ignores taps.

  • 3 third-party services on the page

    3 third-party services load with your homepage (Cookiebot, Google Tag Manager and Sentry), adding 142 KiB and 65 ms of main-thread time.

  • 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.

3 checks passed

  • Mobile performance score: 90

    90/100

    Your mobile performance score is 90 (desktop: 80). That is in Google's “good” band (90 and up).

  • Main-thread work: 1.7 s

    A phone's processor spends 1.7 s on main-thread work while loading, 952 ms of it running JavaScript. That is comfortably low.

  • Server response: 25 ms

    25 ms

    Your server sent the HTML in 25 ms, well inside Google's 600 ms guideline.

Core Web Vitals

7 to fix67

  • Largest Contentful Paint: 2.9 s

    2.9 s

  • First Contentful Paint: 1.8 s

    1.8 s

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

  • Largest content (LCP) held steady for real visitors

    -4%

    Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 4.3 s to 4.1 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Real-user TTFB: 659 ms

    659 ms

    Real visitors wait 659 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • Tap response (INP) got 27% faster for real visitors

    -27%

    Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 279 ms to 202 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Total Blocking Time: 92 ms

  • Cumulative Layout Shift: 0

    0

Images and page weight

100

  • About 0.5 g of CO₂ per visit

    0.54 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.54 g of CO₂e: 64.4 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: 1.9 MB in 100 requests

    1.9 MB

    Your homepage downloads 1.9 MB in 100 requests on a phone: scripts 1.5 MB (73), other files 113 KiB (9) and HTML 108 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

Google 100100
2 checks passed

  • Every image has alt text

    All 18 images in the HTML carry an alt attribute.

  • 48 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 48 WCAG 2.2 A/AA and best-practice rules on the phone render: 48 passed and 0 failed. 2 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

Google 100100

  • 92 internal links, 15 external

    The homepage links to 92 pages on mentimeter.com and 15 external pages.

8 checks passed

  • Meta description: 143 characters

    Your meta description is 143 characters: “Engage your audience with live polls, quizzes, and Q&A. Create interactive presentations in minutes. Perfect for meetin…”.

  • One H1 headline

    Your main headline reads: “Presentations get better when people get involved”.

  • Title: 64 characters

    Your title is a healthy 64 characters: “Interactive presentation & audience engagement tool - Mentimeter”.

  • Canonical URL set

    The canonical URL is https://www.mentimeter.com/.

  • Structured data in place

    Structured data found: Organization, WebApplication and WebSite.

  • 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.mentimeter.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 (746 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes /llms.txt (5 KiB, 27 links), a plain-text guide to the site for AI tools.

Other pages

100

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 44 found) and read each the way a search engine does.

7 checks passed

Best practices

1 to fixGoogle 10093

  • 3 small tap targets

    3 of 8 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • Missing source maps

    Large scripts ship without source maps.

2 checks passed

  • No console errors

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

  • Mobile viewport set

    The page declares a mobile viewport.

Security and trust

1 to fix94

  • No Content-Security-Policy

    No Content-Security-Policy header, the main browser-side defence against injected scripts.

  • No X-Content-Type-Options

    X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

  • 1 link through redirect chains

    1 link go through two or more redirects, for example https://instagram.com/Mentimeter.

  • security.txt has expired

    Your security.txt expired on 2026-10-02, so researchers may not trust its contact details.

  • No Permissions-Policy

    No Permissions-Policy header to switch off camera, microphone and location for embedded content.

7 checks passed

  • Served over HTTPS

    The homepage is served over HTTPS (mentimeter.com).

  • Valid certificate (44 days left)

    The certificate from Let's Encrypt · YR1 verifies for mentimeter.com and is valid for another 44 days.

  • Protected from clickjacking

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

  • HSTS enabled

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

  • http:// redirects to https

    http://mentimeter.com redirects to the secure version.

  • HTTP/2

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

  • All 48 links work

    All 48 links checked from your homepage (40 internal, 8 external) answered without errors.

Domain and trust

  • DNSSEC is off

    mentimeter.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.

3 checks passed

  • Domain is 15 years old

    15 years

    mentimeter.com was registered in Jun 2011 through Ascio Technologies, Inc. Danmark - Filial af Ascio technologies, Inc. USA. An established domain carries more trust with email providers and search engines.

  • Certificate issuers are restricted

    CAA records allow only letsencrypt.org, pki.goog, sectigo.com and globalsign.com to issue certificates for mentimeter.com, so a mis-issued certificate from anyone else is refused.

  • Registered until Jun 2028

    mentimeter.com is registered until Jun 2028.

Content and conversion

5 to fix69

  • 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 phone number on the homepage

    A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

  • Thin social proof

    Social proof on the homepage: 2 testimonial or review blocks. Pairing it with named testimonials or customer logos makes it far more convincing.

  • No analytics detected

    No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

  • 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 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.

  • 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.

  • About 637 words of copy

    The homepage carries about 637 words of visible text.

3 checks passed

  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Sign up” and “Join”.

  • 10 calls to action

    The homepage has 10 calls to action, for example “Pricing”, “Talk to sales” and “Sign up”.

  • 1 short form

    A short form (1 field at most) is right on the homepage.

Email authentication

95

  • Email authentication score: 95/100

    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: reject

    DMARC tells receivers to reject 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:_spf.google.com include:_spf.salesforce.com ~all”.

  • DKIM signing found

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

Privacy and tracking

  • 1 tracker load before any consent

    1

    Before a visitor clicks anything, the page loads 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.

  • 4 cookies set on arrival

    4

    Opening the homepage sets 4 cookies (measured from a US location before any click).

  • 4 other companies contacted

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

1 checks passed

  • Consent tool: Cookiebot

    A consent management tool (Cookiebot) loads with the page.
