derivemd.com website review

8 images could be 2.4 MB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 9.5 s faster on a phone.

About 644 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 1.5 s faster on a phone.

Your mobile performance score is 37. Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (shgcdn2.com, Vimeo and Klaviyo and others), adding 9.2 MB and 616 ms of main-thread time.

Vimeo costs a phone 169 ms of main-thread work and 8.3 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.

A phone's processor spends 3.2 s on main-thread work while loading, 1.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

Klaviyo costs a phone 123 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.

15 files are served with short cache lifetimes, so returning visitors download them again (124 KiB).

Polyfills for old browsers add 43 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 150 ms faster on a phone.

8 files block the first paint until they finish downloading. Deferring or inlining them could save about 100 ms.

5 long tasks block the main thread while loading, the longest for 75 ms. During a long task the page ignores taps.

About 33 KiB of CSS is downloaded but never applied on this page.

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 20.3 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 20.4 s. Good is under 3.8 s.

Visually, the page fills in at 12.5 s (Speed Index). Good is under 3.4 s.

The layout shifts by 0.627 while loading, so content jumps under the reader's thumb. Good is under 0.1.

The first text or image appears after 3.2 s on a phone. Good is under 1.8 s.

14 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 13.3 MB in 287 requests on a phone: other files 8.7 MB (157), images 2.9 MB (17) and scripts 1.4 MB (80). Under 2 MB keeps phones on slow connections fast.

01ba3cc3-cb1d-4138-be26-db7ed239eefe weighs 2.1 MB. On a phone connection a single image that size takes seconds.

1 image is downloaded at several times the size a phone draws it, for example 01ba3cc3-cb1d-4138-be26-db7ed239eefe at 3,442 px wide, shown at 390 px. Resized copies would save about 1.9 MB.

2 images (2.2 MB) 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 3.78 g of CO₂e: 454.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

Images must have alternative text: 1 element on the page fails this check, rated critical by axe-core.

Heading levels should only increase by one: 3 elements on the page fail this check, rated moderate by axe-core.

Your title is 69 characters, so Google will cut it off around 60: “DE|RIVE®MD Hair Wellness System | Thicker, Healthier Hair Starts Here”.

Your meta description is 177 characters; Google truncates after about 160, so the end of your pitch is cut.

Your <h1> is empty.

The homepage links to 28 pages on derivemd.com and 3 external pages.

A phone browser shows 1,052 words, but the HTML your server sends has only 75. 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.

/pages/quiz, /collections/haircare, /products/derive-daily-support-shampoo, /products/derive-conditioner, /products/derive-daily-hair-serum and /collections/bundles and 4 others have no <h1> headline, so visitors and search engines get no clear main topic.

/pages/quiz, /products/derive-daily-hair-serum and /collections/bundles 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 13 pages linked from your homepage and read each the way a search engine does.

1 third-party cookie is set on load; browsers are restricting these, so whatever relies on them breaks.

3 errors were logged to the browser console while the page loaded, for example “Uncaught Error: Goaffpro is already loaded. This message prevents duplicate loading of the script. Kindly ignore.”.

Large scripts ship without source maps.

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

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://derivemd.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.

derivemd.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.

derivemd.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.

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

No analytics or tag manager detected in the HTML, so you can't measure whether any of these fixes work.

No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

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 1,052 words of visible text.

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 Meta Pixel (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 21 cookies, 5 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 30 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
