49ers.com website review

87 files are served with short cache lifetimes, so returning visitors download them again (1.9 MB).

About 1.1 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.6 s faster on a phone.

Integral Ad Science costs a phone 1.6 s of main-thread work and 738 KiB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

About 141 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 1.5 s faster on a phone.

Google/Doubleclick Ads costs a phone 1.4 s of main-thread work and 1.1 MB of downloads while your page loads. That alone is enough to make taps feel slow. Loading it after the page is usable, or only on the pages that need it, takes that off the critical path.

6 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.3 s.

A phone's processor spends 11.7 s on main-thread work while loading, 7.0 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Your mobile performance score is 23 (desktop: 34). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

The page has 3,354 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Integral Ad Science, Google/Doubleclick Ads and Adobe Tag Manager and others), adding 3.2 MB and 4.3 s of main-thread time.

17 images could be 3.6 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 600 ms faster on a phone.

20 long tasks block the main thread while loading, the longest for 687 ms. During a long task the page ignores taps.

Adobe Tag Manager costs a phone 399 ms of main-thread work and 115 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.

7 KiB could be saved by minifying JavaScript.

Optanon costs a phone 276 ms of main-thread work and 290 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.

Google Tag Manager costs a phone 258 ms of main-thread work and 300 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.

Polyfills for old browsers add 51 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

42 KiB JavaScript is shipped twice across bundles.

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 21.8 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “By clicking any of the buttons in this banner, or by clicki…”.

The page becomes fully interactive after 40.0 s. Good is under 3.8 s.

Visually, the page fills in at 13.7 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 6.1 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 2.3 s in total while the page loads. Good is under 200 ms.

Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.5 s (75th percentile). Good is under 1.8 s.

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

The layout shifts by 0.118 while loading, so content jumps under the reader's thumb. Good is under 0.1.

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' tap response (inp) went from 112 ms to 109 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-17, real Chrome visitors' largest content (lcp) went from 2.6 s to 2.8 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 9.7 MB in 328 requests on a phone: images 5.3 MB (89), scripts 3.0 MB (125) and fonts 733 KiB (25). Under 2 MB keeps phones on slow connections fast.

2 images weigh 4.3 MB together. On a phone connection a single image that size takes seconds.

2 images (1.8 MB) 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.

3 images further down the page (192 KiB) download before anyone scrolls to them. Adding loading="lazy" lets the first screen load first.

By the Sustainable Web Design model, a visit to your homepage emits about 2.75 g of CO₂e: 329.5 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Elements must only use permitted ARIA attributes: 2 elements on the page fail this check, rated serious by axe-core.

1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

1 image has no alt text, which hurts accessibility and image search.

All page content should be contained by landmarks: 3 elements on the page fail this check, rated moderate by axe-core.

5 visible links have no text or label, so screen readers cannot say where they go.

ARIA role should be appropriate for the element: 4 elements on the page fail this check, rated minor by axe-core.

Elements marked as presentational should be consistently ignored: 2 elements on the page fail this check, rated minor by axe-core.

Elements with visible text labels do not have matching accessible names. (33 elements).

Headings skip levels (h1 → h3 and h2 → h4), which makes the page harder to scan with a screen reader.

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.

The homepage links to 143 pages on 49ers.com and 67 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.

/80 and /employment/inclusion all use the title “49ers.com | The Official Site of the San Francisco 49ers”, and 1 other title repeat too. Search engines can't tell which page to show for a search, so each competes with the others.

/80, /game-day, /flag and /employment/inclusion use the same meta description. A description written for each page earns more clicks.

/80, /fans and /employment/inclusion have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 15 pages linked from your homepage (of 92 found) and read each the way a search engine does.

20 of 46 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

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

6 errors were logged to the browser console while the page loaded, for example “🚀 Failed to execute data element module core/src/lib/dataElements/customCode.js for data element identityProvider (Loc…”.

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

http://49ers.com does not redirect to https, so some visitors land on the insecure version.

1 link to other sites is dead, for example https://am.ticketmaster.com/49ersnew/ (903).

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.

4 links go through two or more redirects, for example http://www.levisstadium.com/.

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.

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.

49ers.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.

49ers.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.

Social proof on the homepage: 1 trust badge. Pairing it with named testimonials or customer logos makes it far more convincing.

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 3,326 words of visible text.

DMARC is set to p=none, so mail pretending to be 49ers.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 Comscore, Google Ads, Google Tag Manager and Klaviyo (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 16 cookies (measured from a US location before any click).

Loading the homepage contacts 43 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
