filtrous.com website review

About 824 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 3.6 s faster on a phone.

5 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. 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, hiverhq.com and boostcommerce.io and others), adding 2.2 MB and 1.2 s of main-thread time.

About 197 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 900 ms faster on a phone.

23 images could be 587 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 100 ms faster on a phone.

Google Tag Manager costs a phone 545 ms of main-thread work and 486 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 files are served with short cache lifetimes, so returning visitors download them again (69 KiB).

hiverhq.com costs a phone 412 ms of main-thread work and 872 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 3.5 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Polyfills for old browsers add 45 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 300 ms faster on a phone.

10 long tasks block the main thread while loading, the longest for 325 ms. During a long task the page ignores taps.

Shopify costs a phone 38 ms of main-thread work and 629 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.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 100 ms).

20 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.

Your largest element takes 20.0 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 20.8 s. Good is under 3.8 s.

Visually, the page fills in at 7.8 s (Speed Index). Good is under 3.4 s.

Scripts block taps and scrolling for 848 ms in total while the page loads. Good is under 200 ms.

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

Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

Your homepage downloads 4.4 MB in 294 requests on a phone: scripts 1.8 MB (84), other files 1.1 MB (147) and images 695 KiB (32). Under 2 MB keeps phones on slow connections fast.

4 images are downloaded at several times the size a phone draws them, for example ACB-11-3722-white-v1.png at 2,048 px wide, shown at 172 px. Resized copies would save about 214 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 1.23 g of CO₂e: 148.1 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.

Elements with visible text labels do not have matching accessible names. (2 elements).

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

Your meta description is 274 characters; Google truncates after about 160, so the end of your pitch is cut.

Structured data found (WebSite) but with 1 problem, for example “ld+json block 2 is not valid JSON (Unexpected token ',', ..."sameAs": [, "https:"... is not va)”.

The homepage links to 33 pages on filtrous.com and 8 external pages.

A phone browser shows 407 words, but the HTML your server sends has only 115. GPTBot, ClaudeBot and PerplexityBot read that HTML without running JavaScript, so they see an almost empty page. Server-side rendering or pre-rendering fixes it.

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.

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

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

/customer_authentication/redirect has no meta description, so Google writes the search snippet from whatever text it finds.

/pages/quality-v2, /collections/on-sale-v2, /pages/faq-v2, /pages/careers-v2, /pages/contact and /pages/filtrous-field-guide-v2 and 3 others use the same meta description. A description written for each page earns more clicks.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /pages/about, whose canonical is /pages/about-us. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

/customer_authentication/redirect has 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.

2 errors were logged to the browser console while the page loaded, for example “$ is not defined”.

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

HSTS is set, but max-age is 91 days; one year is the recommended minimum.

2 links go through two or more redirects, for example https://filtrous.com/account.

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.

filtrous.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.

Your homepage shows a street address but no LocalBusiness JSON-LD, so Google and AI assistants have to guess your address, hours and phone from the page text.

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

The homepage shows no opening hours. If customers visit or call, show when.

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 407 words of visible text.

DMARC is set to p=none, so mail pretending to be filtrous.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, Google Tag Manager and Klaviyo (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 12 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 21 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
