trekbikes.com website review

54 files are served with short cache lifetimes, so returning visitors download them again (4.7 MB).

About 4.2 MB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 11.8 s faster on a phone.

About 488 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 2.4 s faster on a phone.

Google Tag Manager costs a phone 1.0 s of main-thread work and 859 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.

Your mobile performance score is 36. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

A phone's processor spends 8.0 s on main-thread work while loading, 4.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 6,198 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

8 third-party services load with your homepage (Google Tag Manager, YouTube and Facebook and others), adding 3.0 MB and 2.1 s of main-thread time.

20 long tasks block the main thread while loading, the longest for 712 ms. During a long task the page ignores taps.

YouTube costs a phone 380 ms of main-thread work and 994 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 images could be 254 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

8x8.com costs a phone 104 ms of main-thread work and 493 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 68 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.

Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

3 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.

Your largest element takes 26.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “TK26-NewFor27-HomapageMarquee”.

The page becomes fully interactive after 49.8 s. Good is under 3.8 s.

Visually, the page fills in at 11.4 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 2.4 s in total while the page loads. Good is under 200 ms.

Real visitors wait 2.7 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors wait 311 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

For real visitors the layout shifts by 0.15 (75th percentile). Good is under 0.1.

Over the last 25 four-week periods to 2026-10-03, real Chrome visitors' tap response (inp) went from 313 ms to 410 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Real visitors wait 803 ms 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 4.0 s to 3.7 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 8.2 MB in 205 requests on a phone: scripts 6.7 MB (104), stylesheets 543 KiB (10) and images 521 KiB (16). Under 2 MB keeps phones on slow connections fast.

TK26_NewFor27-HomapageMarquee 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 2.31 g of CO₂e: 277.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Scrollable region must have keyboard access: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

Headings should not be empty: 1 element on the page fails this check, rated minor by axe-core.

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.

Your meta description is 175 characters; Google truncates after about 160, so the end of your pitch is cut.

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

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

The homepage links to 69 pages on trekbikes.com and 8 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 398 of the 782 words a browser shows. AI crawlers don't run JavaScript, so they miss the rest.

There is no https://www.trekbikes.com/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 https://www.trekbikes.com/us/en_US/warrantied_for_life, which answers with an error. Visitors hit a dead end and search engines drop it.

https://www.trekbikes.com/regions, https://www.trekbikes.com/us/en_US/guarantee and https://www.trekbikes.com/us/en_US/store-finder have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 3 pages by a URL that isn't their canonical one, for example https://www.trekbikes.com/us/en_US/c/B507, whose canonical is https://www.trekbikes.com/us/en_US/bikes/electric-bikes/c/B507. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

https://www.trekbikes.com/regions, https://www.trekbikes.com/us/en_US/c/B507, https://www.trekbikes.com/us/en_US/bikes/road-bikes/c/B200, https://www.trekbikes.com/us/en_US/bikes/mountain-bikes/c/B300, https://www.trekbikes.com/us/en_US/bikes/road-bikes/gravel-bikes/c/B546 and https://www.trekbikes.com/us/en_US/bikes/hybrid-bikes/c/B528 and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

https://www.trekbikes.com/us/en_US/bikes/c/B100, https://www.trekbikes.com/us/en_US/store-finder, https://www.trekbikes.com/us/en_US/50th-anniversary-book and https://www.trekbikes.com/us/en_US/the-journey have 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 58 found) and read each the way a search engine does.

1 image failed to load on a phone, for example https://bat.bing.com/action/0?ti=25012299&tm=gtm002&Ver=2&mid=f5e5bd01-29a8-45e3-8008-a47d5c6e0b20&bo=1&sid=f067f050c5d311f1b3858dbab97c8cf1&vid=f0682280c5d311f1aa23b3a63a9337f7&vids=1&msclkid=N&pi=91.

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

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

6 errors were logged to the browser console while the page loaded, for example “Failed to load resource: net::ERR_CONNECTION_CLOSED”.

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

Large scripts ship without source maps.

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.

The homepage carries about 782 words of visible text.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Meta Pixel and Microsoft Ads and 2 mores (measured from a US location before any click). A consent tool (Cookiebot) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 18 cookies, 1 of them by other companies (measured from a US location before any click).

Loading the homepage contacts 46 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
