hydrobuilder.com website review

The page has 4,606 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

Your mobile performance score is 72. Pages that score under 90 lose visitors before the first paint.

5 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.

About 188 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 480 ms faster on a phone.

8 third-party services load with your homepage (Shopify, Google Tag Manager and Klaviyo and others), adding 1.2 MB and 519 ms of main-thread time.

Shopify costs a phone 268 ms of main-thread work and 757 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.

8 images could be 143 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.

About 49 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 180 ms faster on a phone.

3 long tasks block the main thread while loading, the longest for 162 ms. During a long task the page ignores taps.

Polyfills for old browsers add 19 KiB JavaScript that modern phones do not need.

4 files are served with short cache lifetimes, so returning visitors download them again (8 KiB).

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 6.6 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “built for growers mobile banner”.

The page becomes fully interactive after 8.2 s. Good is under 3.8 s.

Visually, the page fills in at 5.1 s (Speed Index). Good is under 3.4 s.

Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 102 ms to 108 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 3.6 MB in 260 requests on a phone: other files 1.3 MB (128), images 1,013 KiB (37) and scripts 910 KiB (75). Under 2 MB keeps phones on slow connections fast.

BioSafe_Homepage_Banner-mobile_f81bc9ee-d266-4784-8ded-b7057 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).

3 images (224 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.

By the Sustainable Web Design model, a visit to your homepage emits about 1.02 g of CO₂e: 121.8 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

[role="img"] and [role="image"] elements must have alternative text: 1 element on the page fails this check, rated serious by axe-core.

All page content should be contained by landmarks: 2 elements on the page fail this check, rated moderate by axe-core.

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 form field has no label, so screen readers announce an empty box and autofill guesses.

Elements with visible text labels do not have matching accessible names. (1 element).

Your title is 67 characters, so Google will cut it off around 60: “Hydroponics Supplies, Grow Lights, Tents & Nutrients | Hydrobuilder”.

The homepage links to 1,215 pages on hydrobuilder.com and 21 external pages.

Your robots.txt lets ChatGPT search (OAI-SearchBot), ChatGPT (ChatGPT-User) and Perplexity (PerplexityBot) read the homepage but closes other sections to them, so answers about those pages can't cite you.

Your homepage links to /pages/brands, which answers with an error. Visitors hit a dead end and search engines drop it.

/pages/contact, /pages/commercial, /pages/grow-diagnostics-plant-health-testing-services, /collections/sale, /collections/new-products and /collections/garden-care-pest-control and 8 others have no <h1> headline, so visitors and search engines get no clear main topic.

/pages/contact, /pages/commercial, /pages/grow-diagnostics-plant-health-testing-services, /collections/sale, /collections/new-products and /collections/garden-care-pest-control and 8 others 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 200 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: the server responded with a status of 404 ()”.

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://hbhold.com/partner-with-us/.

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.

hydrobuilder.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.

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.

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

There is no link to Google or Apple Maps. A directions link is one tap for a phone visitor.

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 895 words of visible text.

DMARC is set to p=none, so mail pretending to be hydrobuilder.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, Klaviyo and Microsoft Ads (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 20 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.
