geeksforgeeks.org website review

3 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.0 s.

Google Tag Manager costs a phone 375 ms of main-thread work and 484 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.

About 341 KiB of JavaScript is downloaded but never used on this page.

4 third-party services load with your homepage (Google Tag Manager, Google/Doubleclick Ads and Google Analytics and others), adding 491 KiB and 377 ms of main-thread time.

6 long tasks block the main thread while loading, the longest for 203 ms. During a long task the page ignores taps.

6 images could be 163 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

About 29 KiB of CSS is downloaded but never applied on this page.

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.

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 3.8 s (75th percentile). Good is under 1.8 s.

The page becomes fully interactive after 8.3 s. Good is under 3.8 s.

Real visitors wait 3.8 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 1.0 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 267 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 191 ms to 194 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 3.2 s to 3.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

6 images further down the page (303 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

6 images (303 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.

By the Sustainable Web Design model, a visit to your homepage emits about 0.40 g of CO₂e: 47.6 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

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

Some lists contain elements other than list items, which screen readers announce wrongly.

All page content should be contained by landmarks: 51 elements on the page fail this check, rated moderate by axe-core.

The page has no <main> landmark, so screen-reader users cannot jump straight to the content.

Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

There is no <h1>, so neither visitors nor Google get a clear main headline.

Your meta description is 207 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (Organization and WebSite) but with 1 problem, for example “WebSite: missing name”.

3 links have no real href, so search engines can't follow them.

No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

The homepage links to 82 pages on geeksforgeeks.org and 8 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.

robots.txt blocks CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.

/dsa/dsa-tutorial-learn-data-structures-and-algorithms, /c/c-programming-language, /cpp/c-plus-plus, /java/java, /python/python-programming-language-tutorial and /javascript/javascript-tutorial and 4 others use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /machine-learning/machine-learning, whose canonical is /machine-learning/machine-learning-tutorial. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/machine-learning/machine-learning took over 3 s to send its HTML from our server.

We fetched 15 pages linked from your homepage (of 69 found) and read each the way a search engine does.

Large scripts ship without source maps.

7 links go through two or more redirects, for example https://www.geeksforgeeks.org/machine-learning/machine-learning/.

X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

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

geeksforgeeks.org'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 317 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 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.

Opening the homepage sets 5 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 6 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
