corelanguages.com website review

About 373 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.0 s faster on a phone.

Your mobile performance score is 58. Pages that score under 90 lose visitors before the first paint.

8 third-party services load with your homepage (Google Tag Manager, Google/Doubleclick Ads and Clarity and others), adding 724 KiB and 621 ms of main-thread time.

86 KiB could be saved by minifying JavaScript.

Google Tag Manager costs a phone 283 ms of main-thread work and 302 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.

9 files block the first paint until they finish downloading. Deferring or inlining them could save about 300 ms.

2 files are served with short cache lifetimes, so returning visitors download them again (27 KiB).

6 long tasks block the main thread while loading, the longest for 157 ms. During a long task the page ignores taps.

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

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

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 3.3 s (75th percentile). Good is under 1.8 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 text “Free language lessons for working professionals”.

The first text or image appears after 4.7 s on a phone. Good is under 1.8 s.

The page becomes fully interactive after 9.6 s. Good is under 3.8 s.

Visually, the page fills in at 6.5 s (Speed Index). Good is under 3.4 s.

Real visitors wait 3.5 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 3.5 s to 4.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

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

By the Sustainable Web Design model, a visit to your homepage emits about 0.26 g of CO₂e: 31.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Contentinfo landmark should not be contained in another landmark: 1 element on the page fails this check, rated moderate by axe-core.

Document should not have more than one contentinfo landmark: 1 element on the page fails this check, rated moderate by axe-core.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

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

Your title is 81 characters, so Google will cut it off around 60: “Free Language Lessons For Professionals: Spanish, German, French | CORE Languages”.

Your meta description is 164 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 80 pages on corelanguages.com and 0 external pages.

Your Organization JSON-LD is missing url, description and contact details. These are the facts AI assistants use to describe a business and to tell it apart from others with a similar name.

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.

We fetched 15 pages linked from your homepage (of 51 found) and read each the way a search engine does.

No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.

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.

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.

corelanguages.com is registered until Nov 2026. If it lapses, the site and its email stop working and someone else can buy the name. Renew it, and turn on auto-renew.

corelanguages.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.

corelanguages.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.

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

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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 595 words of visible text.

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

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 and Microsoft Clarity (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.

Opening the homepage sets 6 cookies (measured from a US location before any click).

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.

Loading the homepage contacts 14 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
