3plearning.com website review

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.7 s.

72 files are served with short cache lifetimes, so returning visitors download them again (1.5 MB).

Your mobile performance score is 78 (desktop: 73). Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Facebook and Wistia and others), adding 1,018 KiB and 842 ms of main-thread time.

3 images could be 635 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 428 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 150 ms faster on a phone.

Google Tag Manager costs a phone 322 ms of main-thread work and 370 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.

7 long tasks block the main thread while loading, the longest for 228 ms. During a long task the page ignores taps.

About 21 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

13 KiB could be saved by minifying JavaScript.

Polyfills for old browsers add 12 KiB JavaScript that modern phones do not need.

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

4 KiB could be saved by minifying CSS.

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.

The page becomes fully interactive after 14.5 s. Good is under 3.8 s.

Your largest element takes 4.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “3p-header-blended-teaching-software”.

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

The first text or image appears after 2.4 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 4.3 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 212 ms in total while the page loads. Good is under 200 ms.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 158 ms to 179 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 3.2 s to 3.4 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.5 MB in 132 requests on a phone: scripts 1.2 MB (38), images 1.1 MB (51) and other files 68 KiB (34). Under 2 MB keeps phones on slow connections fast.

4 images (754 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.

7 images further down the page (828 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

1 image is downloaded at several times the size a phone draws it, for example Mathseeds-ESSA-Badge-1.png at 390 px wide, shown at 48 px. Resized copies would save about 44 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 0.72 g of CO₂e: 86.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Some list items are not inside a list.

7 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 on the page fail this check, rated moderate by axe-core.

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

Structured data found (BreadcrumbList, ImageObject, Organization and WebPage) but with 3 problems, for example “WebPage: thumbnailUrl is not an absolute URL ("/wp-content/uploads/2020/10/3p-header-blended-teachi…”.

No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

6 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

The homepage links to 110 pages on 3plearning.com and 20 external pages.

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.

/giving-back, /software/writing-legends, /software/brightpath, /software/literacyplanet and /packages/better-ways-to-learn-maths have no meta description, so Google writes the search snippet from whatever text it finds.

We fetched 15 pages linked from your homepage (of 40 found) and read each the way a search engine does.

2 of 5 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

5 errors were logged to the browser console while the page loaded, for example “Access to font at 'https://assets-homepages-learning.3plearning.net/wp-content/themes/3plearning/fonts/proxima-nova/Pro…”.

Chrome logged issues while loading the page (“Mixed content”).

1 resource load over plain http on your https page (for example http://7315551.collect.igodigital.com/collect.js); browsers block or warn about them.

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

Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

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

3 links go through two or more redirects, for example https://www.3plearning.com/software/3plearning/purchase/.

No Referrer-Policy header, so full URLs can leak to the sites you link to.

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

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

3plearning.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.

Social proof on the homepage: 7 trust badges. Pairing it with named testimonials or customer logos makes it far more convincing.

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

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

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

The homepage carries about 420 words of visible text.

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.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, LinkedIn Insight and Meta Pixel and 3 mores (measured from a US location before any click). A consent tool (Usercentrics) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 16 cookies (measured from a US location before any click).

Loading the homepage contacts 27 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
