drdennisgross.com website review

130 files are served with short cache lifetimes, so returning visitors download them again (2.2 MB).

About 828 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.

13 files block the first paint until they finish downloading. Deferring or inlining them could save about 2.1 s.

Your mobile performance score is 41 (desktop: 52). Under 50 is Google's “poor” band: many phone visitors leave before the page is usable.

8 third-party services load with your homepage (Optanon, videowise.com and PayPal and others), adding 6.5 MB and 563 ms of main-thread time.

12 images could be 457 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 550 ms faster on a phone.

videowise.com costs a phone 97 ms of main-thread work and 5.6 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 113 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 450 ms faster on a phone.

Polyfills for old browsers add 88 KiB JavaScript that modern phones do not need. Google estimates it would make the page about 350 ms faster on a phone.

57 KiB could be saved by minifying JavaScript.

A phone's processor spends 3.3 s on main-thread work while loading, 1.6 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

The page has 1,899 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

9 long tasks block the main thread while loading, the longest for 164 ms. During a long task the page ignores taps.

Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

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

Real Chrome users on phones do not pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)). Google uses this in ranking.

Your largest element takes 20.9 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 26.7 s. Good is under 3.8 s.

Visually, the page fills in at 12.3 s (Speed Index). Good is under 3.4 s.

The first text or image appears after 5.2 s on a phone. Good is under 1.8 s.

Real visitors wait 3.2 s for the largest content to appear (75th percentile). Good is under 2.5 s.

Real visitors see the first content after 2.4 s (75th percentile). Good is under 1.8 s.

Real visitors wait 1.5 s for your server to start answering (75th percentile). Good is under 800 ms.

Scripts block taps and scrolling for 405 ms in total while the page loads. Good is under 200 ms.

The layout shifts by 0.132 while loading, so content jumps under the reader's thumb. Good is under 0.1.

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

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' tap response (inp) went from 120 ms to 121 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Over the last 25 four-week periods to 2026-10-24, real Chrome visitors' largest content (lcp) went from 2.3 s to 2.5 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

Your homepage downloads 10.1 MB in 262 requests on a phone: media 5.2 MB (3), scripts 2.6 MB (95) and images 1.0 MB (64). Under 2 MB keeps phones on slow connections fast.

Mystery_GWP_Sale_HP_Banner_Mobile_640x815px_Gift-Box.jpg 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).

By the Sustainable Web Design model, a visit to your homepage emits about 2.86 g of CO₂e: 343.3 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 visible link has no text or label, so screen readers cannot say where it goes.

Your meta description is 173 characters; Google truncates after about 160, so the end of your pitch is cut.

No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.

1 link use generic text like “click here” or “learn more”, which tells Google nothing about the page behind it.

No twitter:card tag. X falls back to Open Graph, which is incomplete here.

The homepage links to 125 pages on drdennisgross.com and 6 external pages.

There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

/subscribe-and-save-products, /new and /skincare have no meta description, so Google writes the search snippet from whatever text it finds.

Your homepage links to 1 page by a URL that isn't its canonical one, for example /professional-spa, whose canonical is /on/demandware.store/Sites-ddg_us-Site/en_US/Page-Show. Linking straight to the canonical URL saves crawlers a detour and keeps ranking signals on one address.

We fetched 15 pages linked from your homepage (of 71 found) and read each the way a search engine does.

2 images failed to load on a phone, for example https://bat.bing.com/action/0?ti=4038587&tm=gtm002&Ver=2&mid=f6954c73-1b4c-493c-9b7b-62a30310c235&bo=3&sid=deb9f8f0d30c11f1ab6247ed77ecdfb3&vid=deba2010d30c11f185822dc55f9c9f94&vids=1&msclkid=N&pi=918.

27 of 96 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

The page uses 1 deprecated browser API that will stop working in future browsers (“Unload event listeners are deprecated and will be removed.”).

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

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

8 images are displayed at the wrong aspect ratio, so they look stretched or squashed.

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

Large scripts ship without source maps.

No Content-Security-Policy header, the main browser-side defence against injected scripts.

2 links go through two or more redirects, for example https://www.drdennisgross.com/e-gift-card.

No Permissions-Policy header to switch off camera, microphone and location for embedded content.

There is no /.well-known/security.txt telling researchers how to report a security problem to you.

drdennisgross.com is registered until Jan 2027. Make sure auto-renew is on and the card on file is current.

drdennisgross.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.

drdennisgross.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.

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

Your phone number appears as text but isn't a tel: link, so phone visitors can't tap to call.

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 815 words of visible text.

The page uses urgency cues (a countdown or limited-time wording).

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 Microsoft Ads (measured from a US location before any click). A consent tool (OneTrust) is installed; check it blocks these until visitors agree where the law requires it.

Opening the homepage sets 43 cookies (measured from a US location before any click).

Loading the homepage contacts 39 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
