tsunamisea.com website review

14 files are served with short cache lifetimes, so returning visitors download them again (341 KiB).

About 535 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.6 s faster on a phone.

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

8 third-party services load with your homepage (Facebook, Klaviyo and Shopify and others), adding 3.2 MB and 825 ms of main-thread time.

Facebook costs a phone 420 ms of main-thread work and 324 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.

A phone's processor spends 3.3 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

10 long tasks block the main thread while loading, the longest for 258 ms. During a long task the page ignores taps.

Klaviyo costs a phone 186 ms of main-thread work and 308 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.

Unpkg costs a phone 4 ms of main-thread work and 1.8 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.

Shopify costs a phone 79 ms of main-thread work and 372 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.

2 images could be 43 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 150 ms faster on a phone.

Polyfills for old browsers add 31 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

42 KiB could be saved by minifying JavaScript.

Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.

Your largest element takes 12.0 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image.

The page becomes fully interactive after 25.7 s. Good is under 3.8 s.

Visually, the page fills in at 8.9 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 4.4 s on a phone. Good is under 1.8 s.

Scripts block taps and scrolling for 449 ms in total while the page loads. Good is under 200 ms.

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

Over the last 25 four-week periods to 2026-11-07, real Chrome visitors' tap response (inp) went from 107 ms to 113 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 4.8 MB in 366 requests on a phone: scripts 3.0 MB (78), other files 1.5 MB (251) and fonts 96 KiB (2). Under 2 MB keeps phones on slow connections fast.

By the Sustainable Web Design model, a visit to your homepage emits about 1.36 g of CO₂e: 162.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

All page content should be contained by landmarks: 18 elements on the page fail this check, rated moderate by axe-core.

Headings skip levels (h2 → h5), which makes the page harder to scan with a screen reader.

No meta description, so Google writes its own snippet from whatever text it finds.

Your title is only 11 characters: “Tsunami Sea”. Between 30 and 65 characters leaves room to say what you do and for whom.

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

No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

Your <h1> is empty.

The homepage links to 26 pages on tsunamisea.com and 24 external pages.

https://tsunamisea.com/customer_authentication/redirect has no <title>, so Google invents the link text in results.

https://tsunamisea.com/customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

https://tsunamisea.com/pages/tickets, https://tsunamisea.com/collections/apparel, https://tsunamisea.com/collections/music, https://tsunamisea.com/pages/stay-updated, https://tsunamisea.com/collections/all and https://tsunamisea.com/customer_authentication/redirect and 4 others have no meta description, so Google writes the search snippet from whatever text it finds.

https://tsunamisea.com/collections/apparel, https://tsunamisea.com/collections/music, https://tsunamisea.com/collections/all and https://tsunamisea.com/customer_authentication/redirect have no <h1> headline, so visitors and search engines get no clear main topic.

We fetched 11 pages linked from your homepage and read each the way a search engine does.

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

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.

The homepage has only about 43 words of visible text; thin pages give Google and first-time buyers little to go on.

No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

Before a visitor clicks anything, the page loads Google Ads, Google Analytics, Google Tag Manager, Klaviyo and Meta Pixel and 1 more (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 13 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 25 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
