Not measured in this review.
Images and page weight
About 0.00 g of CO₂ per visit
0.00 gBy the Sustainable Web Design model, a visit to your homepage emits about 0.00 g of CO₂e: 0.0 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.
1 checks passed
Page weight: 1 KiB
1 KiBYour homepage downloads 1 KiB on a phone, 1 KiB of it images (20%). That is a lean page.
Accessibility
Documents must have <title> element to aid in navigation (1 element)
Documents must have <title> element to aid in navigation: 1 element on the page fails this check, rated serious by axe-core.
<html> element must have a lang attribute (1 element)
<html> element must have a lang attribute: 1 element on the page fails this check, rated serious by axe-core.
No main landmark
The page has no <main> landmark, so screen-reader users cannot jump straight to the content.
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.
No page language
The <html> element has no lang attribute, so screen readers may read the page in the wrong voice and accent.
1 checks passed
1 automated accessibility rule passed
axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 5 WCAG 2.2 A/AA and best-practice rules on the phone render: 1 passed and 4 failed. Automated rules catch about a third of accessibility problems; the rest need manual testing.
SEO
No page title
Your page has no <title>, so Google has to invent the blue link in search results.
No meta description
No meta description, so Google writes its own snippet from whatever text it finds.
No H1 headline
There is no <h1>, so neither visitors nor Google get a clear main headline.
No structured data
No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.
No canonical URL
No canonical URL, so duplicate versions of the homepage (with or without www, with tracking parameters) can split ranking signals.
No social preview image
No Open Graph image (also missing: og:title, og:description), so links shared on LinkedIn, Slack or Facebook show no preview picture.
No XML sitemap
No XML sitemap at https://avinger.com/sitemap.xml, so Google discovers your pages only by following links.
Only 0 internal links
The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.
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 incomplete here.
1 checks passed
robots.txt in place
robots.txt is in place.
AI search readiness
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.
1 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.
Best practices
No mobile viewport
No viewport meta tag, so phones render the desktop layout zoomed out.
No HTML doctype
The page has no <!DOCTYPE html>, so browsers render it in quirks mode.
1 checks passed
No console errors
No JavaScript errors were logged while the page loaded on a phone.
Security and trust
No HSTS header
No Strict-Transport-Security header, so browsers may still try plain http first on a return visit.
No Content-Security-Policy
No Content-Security-Policy header, the main browser-side defence against injected scripts.
No clickjacking protection
Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.
No X-Content-Type-Options
X-Content-Type-Options: nosniff is missing, so browsers may guess file types.
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.
No security.txt
There is no /.well-known/security.txt telling researchers how to report a security problem to you.
4 checks passed
Served over HTTPS
The homepage is served over HTTPS (avinger.com).
Valid certificate (55 days left)
The certificate from Let's Encrypt · YE2 verifies for avinger.com and is valid for another 55 days.
http:// redirects to https
http://avinger.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.
Domain and trust
No CAA record
avinger.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.
DNSSEC is off
avinger.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.
2 checks passed
Domain is 26 years old
26 yearsavinger.com was registered in Apr 2000 through Bizcn.com, Inc.. An established domain carries more trust with email providers and search engines.
Registered until Apr 2028
avinger.com is registered until Apr 2028.
Content and conversion
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 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.
Only about 0 words
The homepage has only about 0 words of visible text; thin pages give Google and first-time buyers little to go on.
No form on the homepage
There is no form on the homepage, so every lead has to click through to another page first.
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.
Email authentication
Domain receives no email
avinger.com 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: 90/100
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.
3 checks passed
DMARC policy: quarantine
DMARC tells receivers to quarantine mail that fails authentication, and sends you reports.
SPF with a strict ending (-all)
An SPF record lists your sending servers and tells receivers to reject anything else: “v=spf1 include:spf.163.com -all”.
DKIM signing found
A DKIM key is published (selector “default”), so receivers can verify mail really came from you.
Privacy and tracking
1 cookie set on arrival
1Opening the homepage sets 1 cookie (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.

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).
