Not measured in this review.

• Page weight: 3.6 MB

  3.6 MB

  Your homepage downloads 3.6 MB on a phone, 584 KiB of it images (16%). Under 2 MB keeps phones on slow connections fast.

• An image on the first screen is lazy-loaded

  CN_banner_ga_voor_goud_mobile.png 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).

  Elements (2)

• 1 image far larger than shown

  92 KiB

  1 image is downloaded at several times the size a phone draws it, for example CN_sportvoeding_collectie_image.webp at 362 px wide, shown at 48 px. Resized copies would save about 92 KiB.

  Elements (1)

• 3 images in older formats

  3 images (209 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 (3)

• 1 image below the first screen load straight away

  1 image further down the page (32 KiB) download before anyone scrolls to it. Adding loading="lazy" lets the first screen load first.

  1.02 g

  Elements (3)

• Landmarks should have a unique role or role/label/title (i.e. accessible name) combination (1 element)

  Elements (1)

• 1 form field without a label

  1 form field has no label, so screen readers announce an empty box and autofill guesses.

  View source

• Headings skip levels

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

  View source

• 335 internal links, 20 external

  The homepage links to 335 pages on cnsupplements.com and 20 external pages.

• 5 pages without a meta description

  /blogs/free-recipes, /pages/gratis-trainingsschemas, /pages/benchbooster-v2, /pages/about-clean-nutrition and /pages/topsporters-team-goud have no meta description, so Google writes the search snippet from whatever text it finds.

  Elements (5)

• 7 pages without an H1

  /blogs/free-articles, /blogs/free-recipes, /blogs/groei-maat-verhalen, /pages/gratis-trainingsschemas, /pages/benchbooster-v2 and /pages/topsporters-team-goud and 1 other 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 104 found) and read each the way a search engine does.

• 2 broken images

  2 images failed to load on a phone, for example https://bat.bing.com/action/0?ti=187188675&Ver=2&mid=c37fb469-208b-40d2-95e6-72c7be862513&bo=5&sid=7b10fda0d80511f1959443d06e7f739a&vid=7b112900d80511f1bf380ba7f5ac6fbd&vids=1&msclkid=N&pi=918639831&l.

• 2 JavaScript errors while loading

• 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://b2b.cnsupplements.com/customer_authentication/redirect?locale=nl&region_country=NL.

• 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.

• No CAA record

  cnsupplements.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

  cnsupplements.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.

• 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.

• About 1,201 words of copy

  The homepage carries about 1,201 words of visible text.

• DMARC is monitor-only (p=none)

• 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.
