fitbit.com website review

1 file blocks the first paint until they finish downloading. Deferring or inlining it could save about 1.9 s.

Google CDN costs a phone 1.1 s of main-thread work and 1.7 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.

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

The page has 5,778 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

A phone's processor spends 4.1 s on main-thread work while loading, 2.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

6 third-party services load with your homepage (Google CDN, Google Tag Manager and Google Analytics and others), adding 4.5 MB and 1.3 s of main-thread time.

About 986 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 750 ms faster on a phone.

15 long tasks block the main thread while loading, the longest for 843 ms. During a long task the page ignores taps.

47 files are served with short cache lifetimes, so returning visitors download them again (309 KiB).

About 387 KiB of CSS is downloaded but never applied on this page.

12 images could be 308 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

Other Google APIs/SDKs costs a phone 0 ms of main-thread work and 1.6 MB 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 109 ms of main-thread work and 516 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 Fonts costs a phone 0 ms of main-thread work and 605 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.

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.

For real visitors the layout shifts by 1.00 (75th percentile). Good is under 0.1.

Your largest element takes 10.5 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the text “Make every move a healthy one with Google Pixel and Fitbit.”.

The page becomes fully interactive after 28.1 s. Good is under 3.8 s.

The first text or image appears after 5.4 s on a phone. Good is under 1.8 s.

Visually, the page fills in at 9.5 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 835 ms 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 wait 306 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

Real visitors see the first content after 2.7 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.7 s for your server to start answering (75th percentile). Good is under 800 ms.

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 279 ms to 321 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 3.6 s to 4.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 6.6 MB in 154 requests on a phone: scripts 2.5 MB (49), images 1.6 MB (77) and fonts 1.3 MB (6). Under 2 MB keeps phones on slow connections fast.

7 images (312 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.

2 images further down the page (55 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 1.88 g of CO₂e: 225.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Landmarks should have a unique role or role/label/title (i.e. accessible name) combination: 1 element on the page fails this check, rated moderate by axe-core.

1 visible link has no text or label, so screen readers cannot say where it goes.

Elements with visible text labels do not have matching accessible names. (14 elements).

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

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

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

Your meta description is 223 characters; Google truncates after about 160, so the end of your pitch is cut.

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

The homepage links to 121 pages on fitbit.com and 2 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.

The HTML your server sends has 886 of the 2,083 words a browser shows. AI crawlers don't run JavaScript, so they miss the rest.

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.

/product/pixel_11_pro, /product/pixel_11_pro_fold, /product/pixel_11, /product/pixel_10a, /category/phones and /magazine/google_fi and 9 others have no <title>, so Google invents the link text in results.

/product/pixel_11_pro, /product/pixel_11_pro_fold, /product/pixel_11, /product/pixel_10a, /category/phones and /magazine/google_fi and 9 others have no meta description, so Google writes the search snippet from whatever text it finds.

/product/pixel_11_pro, /product/pixel_11_pro_fold, /product/pixel_11, /product/pixel_10a, /category/phones and /magazine/google_fi and 9 others have no <h1> headline, so visitors and search engines get no clear main topic.

/product/pixel_10a, /collection/accessories_wall, /magazine/refurbished_devices and /magazine/why_pixel took over 3 s to send their HTML from our server.

We fetched 15 pages linked from your homepage (of 77 found) and read each the way a search engine does.

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

Chrome logged issues while loading the page (“Content security policy”).

Opening https://fitbit.com goes through 3 redirects before the homepage loads.

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

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

google.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.

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 trust badge. 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.

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 2,083 words of visible text.

DMARC is set to p=none, so mail pretending to be fitbit.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 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 (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 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
