linkedin.com website review

About 643 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.2 s faster on a phone.

Your mobile performance score is 37 (desktop: 96). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 7.3 s on main-thread work while loading, 4.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

7 third-party services load with your homepage (Google CDN, protechts.net and px-cloud.net and others), adding 1.2 MB and 1.9 s of main-thread time.

10 files are served with short cache lifetimes, so returning visitors download them again (337 KiB).

Google CDN costs a phone 744 ms of main-thread work and 730 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.

protechts.net costs a phone 505 ms of main-thread work and 105 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.

20 long tasks block the main thread while loading, the longest for 469 ms. During a long task the page ignores taps.

px-cloud.net costs a phone 267 ms of main-thread work and 187 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 66 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.

Polyfills for old browsers add 9 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 150 ms.

Desktop scores 96 but mobile only 37. A gap that wide usually means heavy scripts and images that hit phones hardest.

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.

Your largest element takes 7.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Welcome to your professional community”.

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

Scripts block taps and scrolling for 1.7 s in total while the page loads. Good is under 200 ms.

The first text or image appears after 3.7 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 5.9 s (Speed Index). Good is under 3.4 s.

Real visitors wait 214 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors wait 1.1 s for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 2.0 MB in 57 requests on a phone: scripts 1.4 MB (12), other files 397 KiB (34) and HTML 111 KiB (5). Under 2 MB keeps phones on slow connections fast.

d58zfe6h3ycgq5l1ccjpkrtdn is on the first screen but marked loading="lazy", so the browser waits before fetching it and the page looks finished later. Load it eagerly (and give it fetchpriority="high" if it is the main image).

By the Sustainable Web Design model, a visit to your homepage emits about 0.57 g of CO₂e: 68.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

1 form field has no label, so screen readers announce an empty box and autofill guesses.

Your title is only 27 characters: “LinkedIn: Log In or Sign Up”. Between 30 and 65 characters leaves room to say what you do and for whom.

No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

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

No XML sitemap at https://www.linkedin.com/sitemap.xml, so Google discovers your pages only by following links.

The homepage links to 147 pages on linkedin.com and 11 external pages.

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.

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.

Your homepage links to /pub/dir/+/+, which answers with an error. Visitors hit a dead end and search engines drop it.

/legal/user-agreement, /legal/privacy-policy and /legal/cookie-policy have no meta description, so Google writes the search snippet from whatever text it finds.

/games has no <h1> headline, so visitors and search engines get no clear main topic.

/games has 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.

We fetched 15 pages linked from your homepage (of 127 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://ponf.linkedin.com/pixel/tracking.png?reqid=8e92e168-f49c-4e8c-adca-34e892d52cf2&pageInstance=urn%3Ali%3Apage%3Ap_homepage-guest-home_jsbeacon%3Bh7o0Ugw%2FQBySMuRQexDglw%3D%3D&js=enabled.

4 third-party cookies are set on load; browsers are restricting these, so whatever relies on them breaks.

1 error was logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_FAILED”.

1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

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

1 link from your homepage to your own site is broken, for example https://www.linkedin.com/pub/dir/+/+?trk=guest_homepage-basic_guest_nav_menu_people (999).

http://linkedin.com does not redirect to https, so some visitors land on the insecure version.

1 link to other sites is dead, for example https://learning.linkedin.com/?src=li-footer&trk=homepage-basic_directory_learningMicrositeUrl (404).

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.

linkedin.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.

linkedin.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 testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

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

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 393 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.

Opening the homepage sets 12 cookies, 3 of them by other companies (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 12 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
