Speed

8 to fix64

  • Reduce unused JavaScript

    1.4 s · 488 KiB

    About 488 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.4 s faster on a phone.

  • Use efficient cache lifetimes

    1.2 s · 119 KiB

    2 files are served with short cache lifetimes, so returning visitors download them again (119 KiB).

  • Improve image delivery

    600 ms · 422 KiB

    23 images could be 422 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

  • Mobile performance score: 64

    64/100

    Your mobile performance score is 64. Pages that score under 90 lose visitors before the first paint.

  • 5 third-party services on the page

    5 third-party services load with your homepage (Google Tag Manager, simplilearn.com and gumlet.com and others), adding 2.6 MB and 572 ms of main-thread time.

  • Google Tag Manager adds 409 ms

    409 ms

    Google Tag Manager costs a phone 409 ms of main-thread work and 335 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.

  • simplilearn.com adds 152 ms

    152 ms

    simplilearn.com costs a phone 152 ms of main-thread work and 2.1 MB 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: 2.5 s

    A phone's processor spends 2.5 s on main-thread work while loading, 808 ms of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 6 long tasks on the main thread

    6 long tasks block the main thread while loading, the longest for 164 ms. During a long task the page ignores taps.

  • Reduce unused CSS

    39 KiB

    About 39 KiB of CSS is downloaded but never applied on this page.

  • Legacy JavaScript

    10 KiB

    Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

1 checks passed

  • Server response: 11 ms

    11 ms

    Your server sent the HTML in 11 ms, well inside Google's 600 ms guideline.

Core Web Vitals

6 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.

  • Largest Contentful Paint: 11.7 s

    11.7 s

    Your largest element takes 11.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Learn. Grow. Get Ahead with AI”.

  • Time to Interactive: 12.0 s

    12.0 s

    The page becomes fully interactive after 12.0 s. Good is under 3.8 s.

  • Real-user TTFB: 851 ms

    851 ms

    Real visitors wait 851 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • Total Blocking Time: 375 ms

    375 ms

    Scripts block taps and scrolling for 375 ms in total while the page loads. Good is under 200 ms.

  • Speed Index: 4.0 s

    4.0 s

    Visually, the page fills in at 4.0 s (Speed Index). Good is under 3.4 s.

  • Largest content (LCP) held steady for real visitors

    +3%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.2 s to 2.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

5 checks passed

  • Real-user LCP: 1.8 s

    1.8 s

    Real visitors wait 1.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user CLS: 0.00

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Real-user FCP: 1.6 s

    1.6 s

    Real visitors see the first content after 1.6 s (75th percentile). Good is under 1.8 s.

  • First Contentful Paint: 1.2 s

    1.2 s

    The first text or image appears after 1.2 s, inside the 1.8 s “good” threshold.

  • Cumulative Layout Shift: 0

    0

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

Images and page weight

3 to fix68

  • Page weight: 2.7 MB in 115 requests

    2.7 MB

    Your homepage downloads 2.7 MB in 115 requests on a phone: images 1.5 MB (93), scripts 1.0 MB (9) and HTML 98 KiB (1). Under 2 MB keeps phones on slow connections fast.

  • 13 images below the first screen load straight away

    13 images further down the page (443 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  • 2 images far larger than shown

    104 KiB

    2 images are downloaded at several times the size a phone draws them, for example TTC_Web_Large_IT_homepage.png at 1,292 px wide, shown at 52 px. Resized copies would save about 104 KiB.

  • About 0.8 g of CO₂ per visit

    0.76 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.76 g of CO₂e: 91.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed

  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

Accessibility

1 to fixGoogle 9698

  • 28 text elements with low contrast

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

  • Elements with visible text labels do not have matching accessible names.

    Elements with visible text labels do not have matching accessible names. (2 elements).

2 checks passed

  • Every image has alt text

    All 110 images in the HTML carry an alt attribute.

  • 42 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 43 WCAG 2.2 A/AA and best-practice rules on the phone render: 42 passed and 1 failed. 1 more need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

5 to fixGoogle 6156

  • Page is set to noindex

    The robots meta tag says “noindex, nofollow”: Google is told not to list this page at all.

  • robots.txt blocks all crawlers

    Your robots.txt disallows the whole site for every crawler, so search engines are told to stay out.

  • Blocked from indexing

    Google's crawler is blocked from indexing this page.

  • Canonical points to another host

    Your canonical URL points to simplilearn.com, not simplilearn.net, so Google may credit that host instead.

  • 1 link crawlers can't follow

    1 link has no real href, so search engines can't follow it.

  • 184 internal links, 16 external

    The homepage links to 184 pages on simplilearn.net and 16 external pages.

6 checks passed

  • Meta description: 158 characters

    Your meta description is 158 characters: “Explore 1000+ online courses in AI, data science, cloud, and business - with certifications backed by Microsoft, AWS & …”.

  • One H1 headline

    Your main headline reads: “Explore Our Top Programs”.

  • Title: 61 characters

    Your title is a healthy 61 characters: “Simplilearn | Courses & Certifications for the AI-First World”.

  • Structured data in place

    Structured data found: ItemList.

  • 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://simplilearn.net/sitemap.xml.

AI search readiness

2 to fix53

  • robots.txt blocks 6 AI answer engine crawlers

    6 of 6

    Your robots.txt shuts out ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User), Claude search (Claude-SearchBot), Claude (Claude-User), Perplexity (PerplexityBot) and Perplexity (Perplexity-User). These fetch pages to answer people's questions and cite the source, so your site can't be quoted or linked in those answers.

  • 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 https://simplilearn.net/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.

  • Opted out of AI training for 5 crawlers

    robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers.

1 checks passed

  • Text is in the HTML

    Your server sends the page's text in the HTML (2,023 words), so crawlers that don't run JavaScript still read it.

Other pages

2 to fix68

  • 6 linked pages are broken

    Your homepage links to https://simplilearn.net/skillup-free-online-courses, https://simplilearn.net/authors, https://simplilearn.net/learn-with-ai, https://simplilearn.net/career-roadmap/ai-engineer, https://simplilearn.net/career-roadmap/data-analyst and https://simplilearn.net/career-roadmap/project-manager, which answer with an error. Visitors hit a dead end and search engines drop them.

  • 9 linked pages hidden from search

    https://simplilearn.net/corporate-training, https://simplilearn.net/resources, https://simplilearn.net/courses/ai, https://simplilearn.net/courses/data-science, https://simplilearn.net/courses/machine-learning and https://simplilearn.net/courses/devops and 3 others are marked noindex but linked from your homepage. If they are meant to be found, remove the noindex.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 129 found) and read each the way a search engine does.

5 checks passed

  • Canonical URLs point to themselves

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

  • Every page has a meta description

    All 9 pages that loaded have a meta description.

  • Titles are unique

    Every page we checked has its own title.

  • Every page has an H1

    Each page we checked has a main headline.

  • Every page has a title

    All 9 pages that loaded have a <title>.

Best practices

3 to fixGoogle 9285

  • 17 small tap targets

    17 of 40 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

  • 5 JavaScript errors while loading

    5 errors were logged to the browser console while the page loaded, for example “Access to XMLHttpRequest at 'https://www.simplilearn.com/resources/api/v1/getMenuRevampData?countryId=34&clusterId=6&me…”.

  • 15 distorted images

    15 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

  • Missing source maps

    Large scripts ship without source maps.

1 checks passed

  • Mobile viewport set

    The page declares a mobile viewport.

Content and conversion

1 to fix92

  • 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 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 1,332 words of copy

    The homepage carries about 1,332 words of visible text.

5 checks passed

  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “Try Simplilearn for Business”.

  • 2 calls to action

    The homepage has 2 calls to action, for example “Try Simplilearn for Business” and “Contact us”.

  • 1 short form

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

  • Social proof on the page

    Social proof on the homepage: 2 testimonial or review blocks, 1 customer or partner logo, a star rating and 4 trust badges.

  • Analytics in place

    Analytics detected: Google Tag Manager.

Privacy and tracking

1 to fix

  • 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). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

  • 2 cookies set on arrival

    2

    Opening the homepage sets 2 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.

  • 9 other companies contacted

    Loading the homepage contacts 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

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 simplilearn.net, because details like these could help someone attack a site. Every review keeps them private, whatever they found.
