Speed

9 to fix55
  • Reduce unused JavaScript

    2.4 s · 475 KiB

    About 475 KiB of JavaScript is downloaded but never used on this page. Google estimates it would make the page about 2.4 s faster on a phone.

  • 3,389 HTML elements

    The page has 3,389 HTML elements. Above 1,500, rendering and every interaction get slower on phones.

  • Mobile performance score: 55

    55/100

    Your mobile performance score is 55. Pages that score under 90 lose visitors before the first paint.

  • Reduce unused CSS

    600 ms · 82 KiB

    About 82 KiB of CSS is downloaded but never applied on this page. Google estimates it would make the page about 600 ms faster on a phone.

  • Render-blocking requests

    650 ms

    7 files block the first paint until they finish downloading. Deferring or inlining them could save about 650 ms.

  • 2 long tasks on the main thread

    2 long tasks block the main thread while loading, the longest for 482 ms. During a long task the page ignores taps.

  • 7 third-party services on the page

    7 third-party services load with your homepage (Shopify, Key CDN and Google CDN and others), adding 1.1 MB and 180 ms of main-thread time.

  • Main-thread work: 2.4 s

    A phone's processor spends 2.4 s on main-thread work while loading, 1.3 s of it running JavaScript. Above 2 s, taps and scrolls feel sluggish.

  • Shopify adds 66 ms

    66 ms

    Shopify costs a phone 66 ms of main-thread work and 836 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.

  • Improve image delivery

    150 ms · 63 KiB

    6 images could be 63 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.

  • Font display

    50 ms

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

  • Legacy JavaScript

    10 KiB

    Polyfills for old browsers add 10 KiB JavaScript that modern phones do not need.

  • Use efficient cache lifetimes

    9 KiB

    5 files are served with short cache lifetimes, so returning visitors download them again (9 KiB).

  • 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.

1 checks passed
  • Server response: 17 ms

    17 ms

    Your server sent the HTML in 17 ms, well inside Google's 600 ms guideline.

Core Web Vitals

7 to fix67
  • Fails Core Web Vitals for real visitors

    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.

  • Largest Contentful Paint: 21.4 s

    21.4 s

    Your largest element takes 21.4 s to render on a phone. Google's threshold for “good” is 2.5 s. The largest element is the element shown below.

  • Time to Interactive: 22.5 s

    22.5 s

    The page becomes fully interactive after 22.5 s. Good is under 3.8 s.

  • Speed Index: 12.0 s

    12.0 s

    Visually, the page fills in at 12.0 s (Speed Index). Good is under 3.4 s.

  • First Contentful Paint: 3.4 s

    3.4 s

    The first text or image appears after 3.4 s on a phone. Good is under 1.8 s.

  • Real-user LCP: 3.0 s

    3.0 s

    Real visitors wait 3.0 s for the largest content to appear (75th percentile). Good is under 2.5 s.

  • Total Blocking Time: 237 ms

    237 ms

    Scripts block taps and scrolling for 237 ms in total while the page loads. Good is under 200 ms.

  • Tap response (INP) held steady for real visitors

    -6%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' tap response (inp) went from 103 ms to 97 ms at the 75th percentile (Chrome UX Report (opens in a new tab) history).

  • Largest content (LCP) held steady for real visitors

    +5%

    Over the last 25 four-week periods to 2026-10-31, real Chrome visitors' largest content (lcp) went from 1.9 s to 2.0 s at the 75th percentile (Chrome UX Report (opens in a new tab) history).

5 checks passed
  • Real-user INP: 118 ms

    118 ms

    Real visitors wait 118 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: 1.4 s

    1.4 s

    Real visitors see the first content after 1.4 s (75th percentile). Good is under 1.8 s.

  • Real-user TTFB: 681 ms

    681 ms

    Real visitors wait 681 ms for your server to start answering (75th percentile). Good is under 800 ms.

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

Images and page weight

1 to fix70
  • Page weight: 6.6 MB in 342 requests

    6.6 MB

    Your homepage downloads 6.6 MB in 342 requests on a phone: images 4.7 MB (173), scripts 837 KiB (46) and other files 787 KiB (107). Under 2 MB keeps phones on slow connections fast.

  • About 1.9 g of CO₂ per visit

    1.88 g

    By the Sustainable Web Design model, a visit to your homepage emits about 1.88 g of CO₂e: 225.1 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

3 checks passed
  • Images use modern formats

    Every sizeable image is WebP, AVIF or SVG.

  • Images load when needed

    Images below the first screen wait until the visitor scrolls to them.

  • 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 9394
  • 1 text element with low contrast

    1 text element doesn't have enough contrast against the background to read easily, especially outdoors on a phone.

  • Interactive controls must not be nested (1 element)

    Interactive controls must not be nested: 1 element on the page fails this check, rated serious by axe-core.

  • Page should contain a level-one heading (1 element)

    Page should contain a level-one heading: 1 element on the page fails this check, rated moderate by axe-core.

  • 4 links without text

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

  • Alternative text of images should not be repeated as text (6 elements)

    Alternative text of images should not be repeated as text: 6 elements on the page fail this check, rated minor by axe-core.

2 checks passed
  • Every image has alt text

    All 211 images in the HTML carry an alt attribute.

  • 48 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 53 WCAG 2.2 A/AA and best-practice rules on the phone render: 48 passed and 5 failed. 3 mores need a person to judge. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

3 to fixGoogle 10082
  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • Meta description is long (320 characters)

    Your meta description is 320 characters; Google truncates after about 160, so the end of your pitch is cut.

  • No social preview image

    No Open Graph image, so links shared on LinkedIn, Slack or Facebook show no preview picture.

  • No X (Twitter) card tag

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

  • 460 internal links, 20 external

    The homepage links to 460 pages on andymark.com and 20 external pages.

5 checks passed
  • Title: 41 characters

    Your title is a healthy 41 characters: “Educational Robotic Parts - AndyMark, Inc”.

  • Canonical URL set

    The canonical URL is https://andymark.com/.

  • Structured data in place

    Structured data found: WebSite.

  • 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://andymark.com/sitemap.xml.

AI search readiness

1 to fix88
  • No Organization structured data

    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.

  • Opted out of AI training for 5 crawlers

    robots.txt blocks GPTBot, ClaudeBot, Google-Extended, Applebot-Extended and CCBot, which collect pages to train models. That's a legitimate choice and doesn't by itself stop the site appearing in AI answers, which the crawlers above handle.

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.

  • Text is in the HTML

    Your server sends the page's text in the HTML (1,891 words), so crawlers that don't run JavaScript still read it.

  • llms.txt published

    The site publishes /llms.txt (6 KiB, 8 links), a plain-text guide to the site for AI tools.

Other pages

4 to fix68
  • 1 page without a title

    /customer_authentication/redirect has no <title>, so Google invents the link text in results.

  • 1 linked page hidden from search

    /customer_authentication/redirect is marked noindex but linked from your homepage. If it is meant to be found, remove the noindex.

  • 14 pages without a meta description

    /apps/wishlist, /customer_authentication/redirect, /collections/new-for-2026, /collections/new-for-2025, /collections/new-for-2024 and /collections/new-for-2023 and 8 others have no meta description, so Google writes the search snippet from whatever text it finds.

  • 12 pages without an H1

    /apps/wishlist, /customer_authentication/redirect, /collections/new-for-2026, /collections/new-for-2025, /collections/new-for-2024 and /collections/new-for-2023 and 6 others have no <h1> headline, so visitors and search engines get no clear main topic.

  • 15 internal pages checked

    We fetched 15 pages linked from your homepage (of 198 found) and read each the way a search engine does.

3 checks passed
  • Linked pages load

    All 15 pages we checked loaded without an error.

  • Canonical URLs point to themselves

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

  • Titles are unique

    Every page we checked has its own title.

Best practices

Google 100100
  • Missing source maps

    Large scripts ship without source maps.

3 checks passed
  • No console errors

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

  • Tap targets are thumb-sized

    43 of 45 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.

  • 1 link through redirect chains

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

  • 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 (andymark.com).

  • Valid certificate (80 days left)

    The certificate from Let's Encrypt · YE1 verifies for andymark.com and is valid for another 80 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://andymark.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 49 links work

    All 49 links checked from your homepage (40 internal, 9 external) answered without errors.

Domain and trust

  • DNSSEC is off

    andymark.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 27 years old

    27 years

    andymark.com was registered in Jan 1999 through GoDaddy.com, LLC. An established domain carries more trust with email providers and search engines.

  • Certificate issuers are restricted

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

  • Registered until Jan 2028

    andymark.com is registered until Jan 2028.

Content and conversion

4 to fix50
  • No call to action on the first screen

    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 social proof

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

  • No analytics detected

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

  • 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 risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

  • About 315 words of copy

    The homepage carries about 315 words of visible text.

  • Urgency cues

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

2 checks passed
  • 16 calls to action

    The homepage has 16 calls to action, for example “Login/Sign Up”, “Shop All” and “Quick shop”.

  • 2 short forms

    2 short forms (1 field at most) are right on the homepage.

Email authentication

1 to fix85
  • 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: 85/100

    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: reject

    DMARC tells receivers to reject mail that fails authentication, and sends you reports.

  • SPF in place (~all)

    An SPF record lists your sending servers and marks other mail as suspicious (~all): “v=spf1 ip4:184.170.171.139 ip4:50.28.102.120 ip4:209.85.220.65 include:_spf.google.com ~all”.

Privacy and tracking

  • 7 cookies set on arrival

    7

    Opening the homepage sets 7 cookies (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.

  • 10 other companies contacted

    Loading the homepage contacts 10 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.

1 checks passed
  • No known trackers before consent

    No known advertising or analytics trackers load before a visitor clicks anything (measured from a US location before any click).
