tsa.gov website review

58 files are served with short cache lifetimes, so returning visitors download them again (1.1 MB).

About 570 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.7 s faster on a phone.

10 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

Your mobile performance score is 47 (desktop: 52). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Google Tag Manager, digitalgov.gov and mPulse and others), adding 1.8 MB and 940 ms of main-thread time.

Google Tag Manager costs a phone 797 ms of main-thread work and 959 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.

11 long tasks block the main thread while loading, the longest for 275 ms. During a long task the page ignores taps.

A phone's processor spends 2.3 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

site.com costs a phone 16 ms of main-thread work and 724 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 67 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.

5 images could be 128 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Polyfills for old browsers add 8 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 50 ms faster on a phone.

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

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.

2 KiB could be saved by minifying JavaScript.

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.

For real visitors the layout shifts by 0.35 (75th percentile). Good is under 0.1.

Your largest element takes 16.7 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

The page becomes fully interactive after 18.0 s. Good is under 3.8 s.

Visually, the page fills in at 8.6 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 3.1 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 580 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 120 ms to 119 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' largest content (lcp) went from 1.1 s to 1.3 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.4 MB in 98 requests on a phone: scripts 1.8 MB (28), images 740 KiB (27) and other files 713 KiB (25). Under 2 MB keeps phones on slow connections fast.

22_0119_real-id-banner-03_500x281.webp 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 0.96 g of CO₂e: 114.7 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

There are 5 <h1> headlines (“Vote is in!”, “TSA Administrator David P. Cummins launches Horiz…” and “TSA Cares”). One clear main headline is easier for people and search engines.

Your meta description is 271 characters; Google truncates after about 160, so the end of your pitch is cut.

No XML sitemap at http://www.tsa.gov/sitemap.xml, so Google discovers your pages only by following links.

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

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

The homepage links to 163 pages on tsa.gov and 19 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 https://www.tsa.gov/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 132 found) and read each the way a search engine does.

On a 390 px-wide phone the page scrolls sideways, a sign that something is wider than the screen.

6 of 16 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

3 errors were logged to the browser console while the page loaded, for example “Uncaught TypeError: Cannot read properties of undefined (reading 'isCommunityOrSite')”.

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

Large scripts ship without source maps.

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

Social proof on the homepage: 1 customer or partner logo. 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.

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 279 words of visible text.

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 7 cookies, 1 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 15 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
