Speed

9 to fix60
  • Render-blocking requests

    1.1 s

    9 files block the first paint until they finish downloading. Deferring or inlining them could save about 1.1 s.

  • Main-thread work: 5.1 s

    A phone's processor spends 5.1 s on main-thread work while loading, 2.5 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • 4,049 HTML elements

    The page has 4,049 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • 8 third-party services on the page

    8 third-party services load with your homepage (Shopify, gotolstoy.com and myshopify.com and others), adding 1.5 MB and 1.1 s of main-thread time.

  • Mobile performance score: 60

    60/100

    Your mobile performance score is 60. Pages that score under 90 lose visitors before the first paint.

  • Reduce unused JavaScript

    600 ms · 391 KiB

    About 391 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 600 ms faster on a phone.

  • Use efficient cache lifetimes

    150 ms · 306 KiB

    21 files are served with short cache lifetimes, so returning visitors download them again (306 KiB).

  • Shopify adds 331 ms

    331 ms

    Shopify costs a phone 331 ms of main-thread work and 724 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.

  • Reduce unused CSS

    300 ms · 42 KiB

    About 42 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 300 ms faster on a phone.

  • Improve image delivery

    219 KiB

    15 images could be 219 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen.

  • 10 long tasks on the main thread

    10 long tasks block the main thread while loading, the longest for 180 ms. During a long task the page ignores taps.

  • Font display

    100 ms

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

  • Minify JavaScript

    32 KiB

    32 KiB could be saved by minifying JavaScript.

  • Duplicated JavaScript

    8 KiB

    8 KiB JavaScript is shipped twice across bundles.

  • Legacy JavaScript

    7 KiB

    Polyfills for old browsers add 7 KiB JavaScript that modern phones do not need.

  • Chained critical requests

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

  • Forced reflow

    Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.

  • Minify CSS

    2 KiB

    2 KiB could be saved by minifying CSS.

1 checks passed
  • Server response: 14 ms

    14 ms

    Your server sent the HTML in 14 ms, well inside Google's 600 ms guideline.

Core Web Vitals

6 to fix100
  • Time to Interactive: 21.9 s

    21.9 s

    The page becomes fully interactive after 21.9 s. Good is under 3.8 s.

  • Largest Contentful Paint: 7.1 s

    7.1 s

    Your largest element takes 7.1 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the image “Exceptional Care. Real People. Holiday Cheer. ”.

  • Speed Index: 8.3 s

    8.3 s

    Visually, the page fills in at 8.3 s (Speed Index). Good is under 3.4 s.

  • Tap response (INP) got 26% slower for real visitors

    +26%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 146 ms to 189 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Total Blocking Time: 350 ms

    350 ms

    Scripts block taps and scrolling for 350 ms in total while the page loads. Good is under 200 ms.

  • 8 images without width and height

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

  • Largest content (LCP) held steady for real visitors

    +2%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 2.1 s to 2.2 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

8 checks passed
  • Passes Core Web Vitals for real visitors

    Real Chrome users on phones pass Google's Core Web Vitals on this page (28-day field data from the Chrome UX Report (opens in a new tab)).

  • Real-user LCP: 1.6 s

    1.6 s

    Real visitors wait 1.6 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Real-user INP: 171 ms

    171 ms

    Real visitors wait 171 ms for the page to respond to a tap (75th percentile). Good is under 200 ms.

  • Real-user CLS: 0.00

    0.00

    For real visitors the layout shifts by 0.00 (75th percentile). Good is under 0.1.

  • Real-user FCP: 1.1 s

    1.1 s

    Real visitors see the first content after 1.1 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 536 ms

    536 ms

    Real visitors wait 536 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • First Contentful Paint: 1.2 s

    1.2 s

    The first text or image appears after 1.2 s, inside the 1.8 s “good” threshold.

  • Cumulative Layout Shift: 0.004

    0.004

    The layout barely moves while loading (CLS 0.004, good is under 0.1).

Images and page weight

2 to fix64
  • Page weight: 7.2 MB in 289 requests

    7.2 MB

    Your homepage downloads 7.2 MB in 289 requests on a phone: fonts 4.1 MB (17), scripts 1.3 MB (79) and other files 952 KiB (110). Under 2 MB keeps phones on slow connections fast.

  • An image on the first screen is lazy-loaded

    wedding_bands_mobile.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).

  • About 2.0 g of CO₂ per visit

    2.03 g

    By the Sustainable Web Design model, a visit to your homepage emits about 2.03 g of CO₂e: 243.9 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

2 checks passed
  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images are sized for phones

    No image is downloaded at more than three times the size it is drawn on a phone.

Accessibility

5 to fixGoogle 9693
  • 5 text elements with low contrast

    5 text elements don't have enough contrast against the background to read easily, especially outdoors on a phone.

  • Interactive controls must not be nested (3 elements)

    Interactive controls must not be nested: 3 elements on the page fail this check, rated serious by axe-core.

  • 44 images without alt text

    44 images have no alt text, which hurts accessibility and image search.

  • 89 links without text

    89 visible links have no text or label, so screen readers cannot say where they go.

  • All page content should be contained by landmarks (6 elements)

    All page content should be contained by landmarks: 6 elements on the page fail this check, rated moderate by axe-core.

  • Headings skip levels

    Headings skip levels (h2 → h6, h3 → h5 and h2 → h5), which makes the page harder to scan with a screen reader.

1 checks passed
  • 56 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 60 WCAG 2.2 A/AA and best-practice rules on the phone render: 56 passed and 4 failed. 4 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

1 to fixGoogle 9298
  • 3 links with vague text

    3 links use generic text like “click here” or “learn more”, which tells Google nothing about the page behind them.

  • 565 internal links, 7 external

    The homepage links to 565 pages on plumdiamonds.com and 7 external pages.

8 checks passed
  • Meta description: 129 characters

    Your meta description is 129 characters: “Customize your own lab grown diamond ring at Plum Diamonds. Shop now for the perfect, eco-friendly and ethically source…”.

  • One H1 headline

    Your main headline reads: “Exceptional Care. Real People. Holiday Cheer.”.

  • Title: 39 characters

    Your title is a healthy 39 characters: “Lab Grown Diamond Rings | Plum Diamonds”.

  • Canonical URL set

    The canonical URL is https://www.plumdiamonds.com/.

  • Structured data in place

    Structured data found: JewelryStore, Organization and WebSite.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

  • XML sitemap found

    Your XML sitemap is reachable at https://www.plumdiamonds.com/sitemap.xml.

AI search readiness

100
  • No llms.txt

    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.

3 checks passed
  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

  • Organization data: 5 of 6 facts

    Your Organization JSON-LD gives name, url, logo, sameAs (social profiles) and description; contact details would complete it.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,753 words), so crawlers that don't run JavaScript still read it.

Other pages

100
  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 112 found) and read each the way a search engine does.

7 checks passed
  • Linked pages load

    1 page of 15 loaded without an error (the rest turned automated requests away).

  • Canonical URLs point to themselves

    No page we checked hands its ranking to a different URL.

  • Every page has a meta description

  • Every page has an H1

    Each page we checked has a main headline.

  • No linked page is hidden from search

    None of the pages we checked carries a noindex tag.

  • Every page has a title

    All 1 page that loaded have a <title>.

Best practices

1 to fixGoogle 8897
  • 1 distorted image

    1 image is displayed at the wrong aspect ratio, so it looks stretched or squashed.

  • 3 low-resolution images

    3 images are served at too low a resolution for sharp phone screens.

3 checks passed
  • No console errors

    No JavaScript errors were logged while the page loaded on a phone.

  • Tap targets are thumb-sized

    126 of 139 tappable elements near the top are at least 24 px.

  • Mobile viewport set

    The page declares a mobile viewport.

Security and trust

100
  • Short HSTS lifetime

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

  • No Referrer-Policy

    No Referrer-Policy header, so full URLs can leak to the sites you link to.

  • No Permissions-Policy

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

  • Deprecated X-XSS-Protection

    X-XSS-Protection is set to “1; mode=block”; the header is deprecated and can introduce bugs. Use 0 or remove it.

  • No security.txt

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

7 checks passed
  • Served over HTTPS

    The homepage is served over HTTPS (plumdiamonds.com).

  • Valid certificate (61 days left)

    The certificate from Let's Encrypt · YE2 verifies for plumdiamonds.com and is valid for another 61 days.

  • Protected from clickjacking

    X-Frame-Options or a frame-ancestors policy stops other sites framing yours.

  • Content-Security-Policy set

    A Content-Security-Policy is set, the main browser-side defence against injected scripts.

  • http:// redirects to https

    http://plumdiamonds.com redirects to the secure version.

  • HTTP/2 and HTTP/3

    The server speaks HTTP/2 and advertises HTTP/3, so browsers load many files over one connection.

  • All 44 links work

    All 44 links checked from your homepage (40 internal, 4 external) answered without errors.

Domain and trust

  • DNSSEC is off

    plumdiamonds.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.

3 checks passed
  • Domain is 5 years old

    5 years

    plumdiamonds.com was registered in Mar 2021 through GoDaddy.com, LLC. An established domain carries more trust with email providers and search engines.

  • Certificate issuers are restricted

    CAA records allow only globalsign.com, letsencrypt.org, pki.goog and ssl.com to issue certificates for plumdiamonds.com, so a mis-issued certificate from anyone else is refused.

  • Registered until Mar 2027

    plumdiamonds.com is registered until Mar 2027.

Content and conversion

4 to fix78
  • Local business without LocalBusiness data

    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.

  • No phone number on the homepage

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

  • Thin social proof

    Social proof on the homepage: a star rating. Pairing it with named testimonials or customer logos makes it far more convincing.

  • No direct contact details

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

  • No opening hours

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

  • No map or directions link

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

  • About 1,087 words of copy

    The homepage carries about 1,087 words of visible text.

5 checks passed
  • Clear next step on the first screen

    On a phone, the first screen shows a clear next step: “HOME TRY-ON KIT” and “CONTACT”.

  • 39 calls to action

    The homepage has 39 calls to action, for example “Shop All”, “Shop Plum's Picks” and “Home Try-On Kit”.

  • 4 short forms

    4 short forms (2 fields at most) are right on the homepage, asking for an email.

  • Analytics in place

    Analytics detected: Google Tag Manager and TikTok Pixel.

  • Risk reducer mentioned

    A guarantee or risk reducer (money-back, free trial, no credit card or similar) is mentioned on the page.

Email authentication

1 to fix75
  • No DKIM key on the usual selectors

    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 score: 75/100

    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.

2 checks passed
  • DMARC policy: quarantine

    DMARC tells receivers to quarantine mail that fails authentication.

  • SPF in place (~all)

    An SPF record lists your sending servers and marks other mail as suspicious (~all): “v=spf1 include:_spf-usg2.ppe-hosted.com include:secureserver.net ~all”.

Privacy and tracking

1 to fix
  • 5 trackers load before any consent

    5

    Before a visitor clicks anything, the page loads Klaviyo, Pinterest Tag, Reddit Pixel, Snap Pixel and TikTok 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.

  • 38 cookies set on arrival

    38

    Opening the homepage sets 38 cookies, 2 of them by other companies (measured from a US location before any click).

  • No consent tool detected

    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.

  • 40 other companies contacted

    Loading the homepage contacts 40 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

Apps on your store

Your storefront loads 15 apps. Each one is code from another company running for your shoppers.

  • Swym Wishlist Plus · problem reported Oct 2026attackers planted code in its settings that sent shoppers who pressed Checkout to a fake checkout page taking card details. What to do: make sure it's on version 7.0.18 or later, check its settings for code or HTML you didn't add, and test checkout in a private window.

Your store uses an app that was used in an attack. That is not a sign you were hit: check the app as described.
