Not measured in this review.

• Page weight: 2.1 MB

  2.1 MB

  Your homepage downloads 2.1 MB on a phone, 588 KiB of it images (27%). Under 2 MB keeps phones on slow connections fast.

• 2 images in older formats

  2 images (546 KiB) 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.

  Elements (2)

• About 0.6 g of CO₂ per visit

  0.59 g

  By the Sustainable Web Design model, a visit to your homepage emits about 0.59 g of CO₂e: 71.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

• 1 link without text

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

• Headings skip levels

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

  View source

• Title is long (80 characters)

  Your title is 80 characters, so Google will cut it off around 60: “Diagnostics at Abbott | Personalized Solutions for Better Healthcare Performance”.

  View source

• No structured data

  No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

• 11 H1 headlines

  There are 11 <h1> headlines (“Welcome to a new, innovative era of diagnostics”, “Diagnostics at Abbott” and “ABBOTT PANDEMIC DEFENSE COALITION”). One clear main headline is easier for people and search engines.

  View source

• No XML sitemap

  No XML sitemap at https://www.diagnostics.abbott/sitemap-index.xml, so Google discovers your pages only by following links.

• No favicon declared

  No favicon is declared in the HTML, so browser tabs and Google's mobile results may show a generic icon.

• No X (Twitter) card tag

  No twitter:card tag. X falls back to Open Graph, which is set, so this is minor.

• 14 internal links, 36 external

  The homepage links to 14 pages on diagnostics.abbott and 36 external pages.

• 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.

• 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.

• 2 pages share a title

  /us/en/home.html and /int/en/home.html all use the title “Diagnostics at Abbott | Personalized Solutions for Better Healthcare …”. Search engines can't tell which page to show for a search, so each competes with the others.

  Elements (2)

• 3 pages with very little text

  /int/ru/home.html, /int/ja/home.html and /int/zh/home.html 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.

• 11 internal pages checked

  We fetched 11 pages linked from your homepage and read each the way a search engine does.

• 2 small tap targets

  2 of 7 tappable elements near the top of the page are smaller than 24 px, hard to hit with a thumb.

• 2 JavaScript errors while loading

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

• 2 redirects before the homepage

  Opening https://diagnostics.abbott goes through 2 redirects before the homepage loads.

• 1 link through redirect chains

  1 link go through two or more redirects, for example https://www.abbott.com/for-healthcare-professionals/diagnostics.html.

• No security.txt

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

• No CAA record

  diagnostics.abbott 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.

• 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 calls to action

  We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

• 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 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 515 words of copy

  The homepage carries about 515 words of visible text.

• No DMARC policy

  diagnostics.abbott 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.

• No SPF record

  diagnostics.abbott 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.

• 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.

• Domain receives no email

  diagnostics.abbott has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

• Email authentication score: 0/100

  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.

• 1 tracker load before any consent

  1

  Before a visitor clicks anything, the page loads Google Tag Manager (measured from a US location before any click). A consent tool (TrustArc) is installed; check it blocks these until visitors agree where the law requires it.

• 6 cookies set on arrival

  6

  Opening the homepage sets 6 cookies (measured from a US location before any click).

• 13 other companies contacted

  Loading the homepage contacts 13 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
