3helix.com website review

The page goes through 1 redirect before it starts loading, costing about 3.2 s. Link and advertise the final URL directly.

5 third-party services load with your homepage (Shopify, Yotpo and shop.app and others), adding 13.5 MB and 77 ms of main-thread time.

Shopify costs a phone 42 ms of main-thread work and 13.4 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.

About 266 KiB of JavaScript is downloaded but never used on this page.

3 long tasks block the main thread while loading, the longest for 98 ms. During a long task the page ignores taps.

1 image could be 59 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

6 files are served with short cache lifetimes, so returning visitors download them again (26 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.

The page becomes fully interactive after 8.5 s. Good is under 3.8 s.

The first text or image appears after 2.1 s on a phone. Good is under 1.8 s.

1 image 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 14.6 MB in 155 requests on a phone: media 12.8 MB (1), images 981 KiB (4) and scripts 653 KiB (110). Under 2 MB keeps phones on slow connections fast.

1 image is downloaded at several times the size a phone draws it, for example Helix_logo_High_Res_no_bkgrd_3.png at 3,344 px wide, shown at 180 px. Resized copies would save about 59 KiB.

By the Sustainable Web Design model, a visit to your homepage emits about 4.14 g of CO₂e: 496.2 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

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

Headings skip levels (h1 → h3, h2 → h5 and h3 → h5), which makes the page harder to scan with a screen reader.

Your title is 80 characters, so Google will cut it off around 60: “3Helix | Collagen Targeting CHPs for Diagnostics and Histopathology – 3Helix Inc”.

Your meta description is 301 characters; Google truncates after about 160, so the end of your pitch is cut.

The homepage links to 104 pages on 3helix.com and 9 external pages.

We fetched 15 pages linked from your homepage (of 33 found) and read each the way a search engine does.

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

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

1 link go through two or more redirects, for example https://www.3helix.com/customer_authentication/redirect?locale=en&region_country=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.

3helix.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.

No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

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.

A local customer looking to call finds no phone number on the homepage. Add one, ideally as a tap-to-call link.

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 12 words of visible text; thin pages give Google and first-time buyers little to go on.

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.

3helix.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

3helix.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

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 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, 1 of them by other companies (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 9 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
