coolmathgames.com website review

Not measured in this review.

• Fails Core Web Vitals for real visitors

  Real Chrome users on phones do not pass Google's Core Web Vitals on your site (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

• Real-user INP: 294 ms

  294 ms

  Real visitors wait 294 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

• Real-user CLS: 0.11

  0.11

  For real visitors the layout shifts by 0.11 (75th percentile). Good is under 0.1.

• Tap response (INP) held steady for real visitors

  +4%

  Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 287 ms to 297 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

• Largest content (LCP) got 10% slower for real visitors

  +10%

  Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 1.7 s to 1.9 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

• Page weight: 3.4 MB

  3.4 MB

  Your homepage downloads 3.4 MB on a phone, 1.2 MB of it images (35%). Under 2 MB keeps phones on slow connections fast.

• 3 images far larger than shown

  293 KiB

  3 images are downloaded at several times the size a phone draws them, for example papas-pizzeria.png at 560 px wide, shown at 75 px. Resized copies would save about 293 KiB.

  Elements (3)

• 4 images below the first screen load straight away

  4 images further down the page (347 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

  Elements (4)

• 4 images in older formats

  4 images (438 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.

  Elements (4)

• About 1.0 g of CO₂ per visit

  0.95 g

  By the Sustainable Web Design model, a visit to your homepage emits about 0.95 g of CO₂e: 114.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

• 39 tap targets too small

  39 tap targets are too small or too close together to hit reliably with a finger.

  Elements (3)

• Hidden but focusable

  5 elements hidden from screen readers can still receive keyboard focus.

  Elements (3)

• 3 images without alt text

  3 images have no alt text, which hurts accessibility and image search.

  View source

• 2 form fields without a label

  2 form fields have no label, so screen readers announce an empty box and autofill guesses.

• Meta description is long (233 characters)

  Your meta description is 233 characters; Google truncates after about 160, so the end of your pitch is cut.

  View source

• 288 internal links, 28 external

  The homepage links to 288 pages on coolmathgames.com and 28 external pages.

• 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.

• 15 pages without an H1

  /c/strategy-games, /c/idle-games, /c/tower-defense-games, /c/business-games, /c/endless-puzzle-games and /c/match-3-games and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

• 15 pages with very little text

  /c/strategy-games, /c/idle-games, /c/tower-defense-games, /c/business-games, /c/endless-puzzle-games and /c/match-3-games and 9 others have under 150 words in the HTML. Thin pages rarely rank; if the text loads with JavaScript, crawlers that don't run it see even less.

• 15 internal pages checked

  We fetched 15 pages linked from your homepage (of 185 found) and read each the way a search engine does.

• 1 broken image

  1 image failed to load on a phone, for example https://lh3.googleusercontent.com/xzYhFSFhl32UXolGgI1UqHBpnvA_K5I3U2_nzaXr47UlvFrWa3yA5IpAfn3Is9CrS5rPckRjNRTIHuWwicLn3rbCT5flDQrmAlLqcbHT88CH_RhQxDsh=h60.

• 2 JavaScript errors while loading

  2 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_SOCKET_NOT_CONNECTED”.

• No HSTS header

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

• No Content-Security-Policy

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

• No clickjacking protection

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

• No X-Content-Type-Options

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

• No Referrer-Policy

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

• No Permissions-Policy

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

• No security.txt

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

• No CAA record

  coolmathgames.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.

• DNSSEC is off

  coolmathgames.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.

• 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.

• No social proof

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

• 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 form on the homepage

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

• 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 1,951 words of copy

  The homepage carries about 1,951 words of visible text.

• Urgency cues

  The page uses urgency cues (a countdown or limited-time wording).

• No DMARC policy

  coolmathgames.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

• No DKIM key on the usual selectors

  We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

• Email authentication score: 40/100

  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.

• 7 trackers load before any consent

  7

  Before a visitor clicks anything, the page loads Amazon Ads, Criteo, Google Ads, Google Analytics and Google Tag Manager and 2 mores (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.

• 30 cookies set on arrival

  30

  Opening the homepage sets 30 cookies, 2 of them by other companies (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.

• 69 other companies contacted

  Loading the homepage contacts 69 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
