Fix first

Ordered by severity, then by number of affected pages. Info findings are not counted, and checks whose findings are all info are left out.

  1. HTTP is not upgraded to HTTPS (HEALTH-HTTPS-020, error, affected: 1): Install a certificate, serve the site over HTTPS, and redirect every HTTP address to its HTTPS version.
  2. Broken internal link (HEALTH-LINK-001, error, affected: 1): Fix the link to point at a working page, or restore the missing page and redirect it if it moved.
  3. HTML is served without compression (PERF-COMP-020, error, affected: 1): Turn on gzip or Brotli compression for HTML responses in the web server or CDN.
  4. A noindex page is listed in the sitemap (SEO-INDEX-041, error, affected: 1): Remove the page from the sitemap, or remove the noindex directive.
  5. Page has no title (SEO-TITLE-001, error, affected: 1): Add a unique <title> that describes the page in about 50 to 60 characters.

SEO

Page has no title

  • Check: SEO-TITLE-001
  • Severity: error
  • Why: The title is the main heading shown in search results and browser tabs. Without one, search engines pick their own text.
  • Fix: Add a unique <title> that describes the page in about 50 to 60 characters.

Findings (1):

Page Detail
http://127.0.0.1:4173/untitled No <title> element, or it is empty.

Title is shared with other pages

  • Check: SEO-TITLE-003
  • Severity: warning
  • Why: Pages with the same title are hard to tell apart in search results and in browser tabs.
  • Fix: Give each page its own title that describes what is unique about it.

Findings (2):

Page Detail
http://127.0.0.1:4173/dup-a Title is shared with 1 other indexable page. Evidence: http://127.0.0.1:4173/dup-b
http://127.0.0.1:4173/dup-b Title is shared with 1 other indexable page. Evidence: http://127.0.0.1:4173/dup-a

Meta description is very short or very long

  • Check: SEO-DESC-011
  • Severity: info
  • Why: A very short description gives searchers little reason to click. Search results cut long descriptions off.
  • Fix: Write a description between 50 and 160 characters that says what the page offers.
  • Heuristic: Fails below 50 or above 160 characters. Snippet length varies by device and query, so 160 characters is a rule of thumb.

Findings (1):

Page Detail
http://127.0.0.1:4173/untitled Meta description is 40 characters long. A typical range is 50 to 160.

Meta description is shared with other pages

  • Check: SEO-DESC-012
  • Severity: warning
  • Why: Identical descriptions make different pages look the same in search results.
  • Fix: Write a description for each page that reflects its own content.

Findings (2):

Page Detail
http://127.0.0.1:4173/dup-a Meta description is shared with 1 other indexable page. Evidence: http://127.0.0.1:4173/dup-b
http://127.0.0.1:4173/dup-b Meta description is shared with 1 other indexable page. Evidence: http://127.0.0.1:4173/dup-a

Page has more than one h1 heading

  • Check: SEO-H1-021
  • Severity: info
  • Why: HTML allows more than one h1, but a single one keeps the page outline clear for readers and search engines.
  • Fix: Use one <h1> for the page topic and <h2> or lower for sections.

Findings (1):

Page Detail
http://127.0.0.1:4173/two-h1 The page has 2 <h1> headings.

Page has no canonical link

  • Check: SEO-CANON-030
  • Severity: warning
  • Why: A canonical link tells search engines which URL to index when the same content is reachable at several addresses.
  • Fix: Add <link rel="canonical"> pointing at the preferred URL of the page, usually the page itself.

Findings (8):

Page Detail
http://127.0.0.1:4173/ No canonical link found.
http://127.0.0.1:4173/about No canonical link found.
http://127.0.0.1:4173/untitled No canonical link found.
http://127.0.0.1:4173/dup-a No canonical link found.
http://127.0.0.1:4173/dup-b No canonical link found.
http://127.0.0.1:4173/two-h1 No canonical link found.
http://127.0.0.1:4173/form No canonical link found.
http://127.0.0.1:4173/media No canonical link found.

Page is set to noindex

  • Check: SEO-INDEX-040
  • Severity: info
  • Why: Search engines will not list a noindex page. This is listed so you can confirm it is intended.
  • Fix: If the page should appear in search, remove the noindex directive from the meta robots tag and the X-Robots-Tag header.

Findings (1):

Page Detail
http://127.0.0.1:4173/hidden The page carries a noindex directive.

A noindex page is listed in the sitemap

  • Check: SEO-INDEX-041
  • Severity: error
  • Why: The sitemap says the page should be indexed while the page says it should not, so the two signals contradict each other.
  • Fix: Remove the page from the sitemap, or remove the noindex directive.

Findings (1):

Page Detail
http://127.0.0.1:4173/hidden The page is noindex but is listed in the sitemap.

Open Graph tags are missing

  • Check: SEO-OG-060
  • Severity: info
  • Why: Open Graph tags control the title, text and image shown when the page is shared on social networks and in chat apps.
  • Fix: Add og:title, og:description and og:image meta tags to the head.

Findings (8):

Page Detail
http://127.0.0.1:4173/ Missing og:title, og:description, og:image.
http://127.0.0.1:4173/about Missing og:title, og:description, og:image.
http://127.0.0.1:4173/untitled Missing og:title, og:description, og:image.

http://127.0.0.1:4173/form Missing og:title, og:description, og:image.
http://127.0.0.1:4173/media Missing og:title, og:description, og:image.

Structured data is not valid JSON

  • Check: SEO-LD-070
  • Severity: warning
  • Why: Search engines skip a JSON-LD block they cannot parse, so the page loses any rich results it was meant to earn.
  • Fix: Fix the syntax of the JSON-LD block. A JSON validator will point at the error.

Findings (1):

Page Detail
http://127.0.0.1:4173/form A JSON-LD block is not valid JSON.

No robots.txt file

  • Check: SEO-ROBOTS-080
  • Severity: warning
  • Why: Crawlers look for robots.txt first. Without one they assume everything may be crawled and they cannot find the sitemap from it.
  • Fix: Publish a robots.txt at the root of the site, even a short one that links to the sitemap.

Findings (1):

Page Detail
(whole site) robots.txt returned status 404.

robots.txt does not reference the sitemap

  • Check: SEO-MAP-091
  • Severity: info
  • Why: A Sitemap line in robots.txt lets every crawler find the sitemap without being told about it.
  • Fix: Add a line such as Sitemap: https://example.com/sitemap.xml to robots.txt.

Findings (1):

Page Detail
(whole site) A sitemap exists but robots.txt has no Sitemap line.

Page has little text

  • Check: SEO-THIN-100
  • Severity: info
  • Why: Pages with very little text give search engines little to rank. Some pages, such as contact or gallery pages, are fine this way.
  • Fix: If the page should rank, add useful text that answers what visitors come for.
  • Heuristic: Fails below 150 words of visible text. This is a rule of thumb and may be fine for contact or gallery pages.

Findings (8):

Page Detail
http://127.0.0.1:4173/ The page has 77 words of visible text.
http://127.0.0.1:4173/about The page has 62 words of visible text.
http://127.0.0.1:4173/untitled The page has 62 words of visible text.
http://127.0.0.1:4173/dup-a The page has 62 words of visible text.
http://127.0.0.1:4173/dup-b The page has 62 words of visible text.
http://127.0.0.1:4173/two-h1 The page has 66 words of visible text.
http://127.0.0.1:4173/form The page has 67 words of visible text.
http://127.0.0.1:4173/media The page has 62 words of visible text.

Health

Broken internal link

  • Check: HEALTH-LINK-001
  • Severity: error
  • Why: Visitors and search engines who follow the link reach an error page instead of content.
  • Fix: Fix the link to point at a working page, or restore the missing page and redirect it if it moved.
  • Heuristic: A link whose target answered 429 or 503 during the audit is reported as not verified, because the answer says nothing about whether the page exists.

Findings (1):

Page Detail
http://127.0.0.1:4173/missing The URL returns status 404. Evidence: http://127.0.0.1:4173/

Internal link points at a redirect

  • Check: HEALTH-LINK-002
  • Severity: warning
  • Why: Each redirect adds a round trip for visitors and crawlers.
  • Fix: Update the link to point straight at the final address.

Findings (2):

Page Detail
http://127.0.0.1:4173/old-page Redirects to http://127.0.0.1:4173/about Evidence: http://127.0.0.1:4173/
http://127.0.0.1:4173/chain-a Redirects to http://127.0.0.1:4173/dup-a Evidence: http://127.0.0.1:4173/

Redirect chain has more than one hop

  • Check: HEALTH-REDIR-010
  • Severity: warning
  • Why: Every extra hop slows the page down and gives crawlers another chance to give up.
  • Fix: Redirect the first address straight to the final address.

Findings (1):

Page Detail
http://127.0.0.1:4173/chain-a Redirect chain of 2 hops ending at http://127.0.0.1:4173/dup-a. Evidence: http://127.0.0.1:4173/chain-a; http://127.0.0.1:4173/chain-b

HTTP is not upgraded to HTTPS

  • Check: HEALTH-HTTPS-020
  • Severity: error
  • Why: Plain HTTP traffic can be read and changed on the way, and browsers label such sites as not secure.
  • Fix: Install a certificate, serve the site over HTTPS, and redirect every HTTP address to its HTTPS version.

Findings (1):

Page Detail
(whole site) The site is served over plain HTTP.

No favicon

  • Check: HEALTH-FAV-040
  • Severity: info
  • Why: Browsers ask for a favicon to show in tabs and bookmarks. Without one they show a generic icon, and the requests end in 404 errors.
  • Fix: Add a favicon link to the page head, or serve a file at /favicon.ico.

Findings (1):

Page Detail
(whole site) No favicon link in the pages and no /favicon.ico file.

No Content-Security-Policy header

  • Check: HEALTH-HDR-051
  • Severity: info
  • Why: A content security policy limits where scripts and other resources can load from, which reduces the damage of injected code.
  • Fix: Add a Content-Security-Policy header. Start in report-only mode if the site loads many third-party resources.

Findings (1):

Page Detail
(whole site) The start page has no Content-Security-Policy header. 8 other pages also lack it.

No X-Content-Type-Options nosniff header

  • Check: HEALTH-HDR-052
  • Severity: warning
  • Why: Without nosniff, some browsers guess file types and may run a file as a script when it was not meant to be one.
  • Fix: Send X-Content-Type-Options: nosniff on every response.

Findings (1):

Page Detail
(whole site) The start page has no X-Content-Type-Options: nosniff header. 8 other pages also lack it.

No Referrer-Policy header

  • Check: HEALTH-HDR-053
  • Severity: info
  • Why: Without a policy, browsers decide how much of the page address is shared with other sites when a visitor clicks a link.
  • Fix: Send a Referrer-Policy header such as strict-origin-when-cross-origin.

Findings (1):

Page Detail
(whole site) The start page has no Referrer-Policy header. 8 other pages also lack it.

No clickjacking protection

  • Check: HEALTH-HDR-054
  • Severity: info
  • Why: Without X-Frame-Options or a frame-ancestors rule, other sites can embed the page in a frame and trick visitors into clicking hidden controls.
  • Fix: Send X-Frame-Options or add a frame-ancestors rule to the Content-Security-Policy.

Findings (1):

Page Detail
(whole site) The start page has no X-Frame-Options or CSP frame-ancestors header. 8 other pages also lack it.

Performance

HTML is served without compression

  • Check: PERF-COMP-020
  • Severity: error
  • Why: Compression usually cuts the size of HTML by a large share, so pages download faster.
  • Fix: Turn on gzip or Brotli compression for HTML responses in the web server or CDN.
  • Heuristic: Only documents over 1 KB (1024 bytes) are checked, because compressing tiny files gains little.

Findings (1):

Page Detail
http://127.0.0.1:4173/ The 1119 byte HTML response has no gzip, br, deflate or zstd encoding.

Script or stylesheet served without compression

  • Check: PERF-COMP-021
  • Severity: warning
  • Why: Text assets compress well. Sending them as they are wastes bandwidth and slows rendering.
  • Fix: Turn on gzip or Brotli compression for JavaScript and CSS files.
  • Heuristic: Only files over 1 KB (1024 bytes) are checked.

Findings (1):

Page Detail
http://127.0.0.1:4173/assets/plain.css The 2640 byte stylesheet has no compression. Evidence: http://127.0.0.1:4173/media

Static asset is not cached for long

  • Check: PERF-CACHE-030
  • Severity: warning
  • Why: Without a cache lifetime, returning visitors download the same files again on every visit.
  • Fix: Send Cache-Control with a max-age of at least one hour, and a year for files whose names change when they change.
  • Heuristic: Fails when there is no max-age and no Expires, when max-age is under 3600 seconds, or on no-store. Only measured assets on the audited origin are checked.

Findings (2):

Page Detail
http://127.0.0.1:4173/assets/huge.png No Cache-Control or Expires header. Evidence: http://127.0.0.1:4173/media
http://127.0.0.1:4173/assets/plain.css No Cache-Control or Expires header. Evidence: http://127.0.0.1:4173/media

Large image

  • Check: PERF-IMG-050
  • Severity: warning
  • Why: Images are often the largest part of a page.
  • Fix: Resize the image to the size it is shown at and compress it, or use a modern format such as WebP or AVIF.
  • Heuristic: Fails above 300 KB (300000 bytes) and up to 1 MB. A rule of thumb.

Findings (1):

Page Detail
http://127.0.0.1:4173/assets/huge.png The image is 600000 bytes. Evidence: http://127.0.0.1:4173/media

Images without width and height

  • Check: PERF-IMG-052
  • Severity: warning
  • Why: Without both attributes the browser cannot reserve space, so the page jumps as images load.
  • Fix: Add width and height attributes that match the image's own size, and let CSS scale it.
  • Heuristic: Decorative images are counted too, because layout shift applies to them as well.

Findings (1):

Page Detail
http://127.0.0.1:4173/media 1 image lacks a width or height attribute. Evidence: http://127.0.0.1:4173/assets/huge.png

Large JPEG or PNG

  • Check: PERF-IMG-054
  • Severity: info
  • Why: Modern formats such as WebP and AVIF are often smaller at the same quality.
  • Fix: Convert the image to WebP or AVIF, and keep the old format as a fallback only if needed.
  • Heuristic: Fails for JPEG and PNG files over 100 KB (100000 bytes). A modern format may be smaller, but not always.

Findings (1):

Page Detail
http://127.0.0.1:4173/assets/huge.png The image/png image is 600000 bytes. Evidence: http://127.0.0.1:4173/media

Render-blocking script in the head

  • Check: PERF-BLOCK-060
  • Severity: warning
  • Why: A script in the head without async or defer stops the browser from showing the page until it has loaded and run.
  • Fix: Add defer, or async for independent scripts, or move the script to the end of the body.

Findings (1):

Page Detail
http://127.0.0.1:4173/media 1 script in the head blocks rendering. Evidence: http://127.0.0.1:4173/assets/blocking.js

Accessibility

Static checks only. This is not an accessibility audit: contrast, keyboard use, focus order and screen reader behaviour are not tested.

Image without an alt attribute

  • Check: A11Y-ALT-001
  • Severity: warning
  • Why: Screen readers have nothing to say about an image with no alt attribute, and may read out the file name instead.
  • Fix: Add an alt attribute that describes the image. Use alt="" for images that are only decoration.
  • Heuristic: Images marked aria-hidden="true" or role="presentation" are not counted, because screen readers skip them.

Findings (1):

Page Detail
http://127.0.0.1:4173/media 1 image has no alt attribute. Evidence: http://127.0.0.1:4173/assets/huge.png

Form control without a label

  • Check: A11Y-LABEL-010
  • Severity: warning
  • Why: People using screen readers cannot tell what a field is for, and a label also gives a larger target to click.
  • Fix: Add a label element that points at the field, or an aria-label or aria-labelledby attribute.
  • Heuristic: Hidden, submit, button, reset and image inputs are not counted. Image inputs need alt text instead.

Findings (1):

Page Detail
http://127.0.0.1:4173/form 1 form control has no label. Evidence: input[type=text][name=query]

Generic link text

  • Check: A11Y-LINK-021
  • Severity: info
  • Why: People who move through a page by its links hear them out of context, so click here and read more tell them nothing.
  • Fix: Write link text that says where the link goes or what it does.
  • Heuristic: Compares the link text, lower-cased and without trailing punctuation, with: "click here", "here", "read more", "more", "learn more", "link", "this".

Findings (1):

Page Detail
http://127.0.0.1:4173/form 1 link uses generic text such as click here. Evidence: /about

Heading levels are skipped

  • Check: A11Y-HEAD-040
  • Severity: info
  • Why: People who move through a page by its headings expect the levels to nest, and a gap suggests missing content.
  • Fix: Use the next heading level down, and pick levels for structure and not for size.
  • Heuristic: Fails when a heading is more than one level deeper than the heading before it.

Findings (1):

Page Detail
http://127.0.0.1:4173/form 1 heading level is skipped. Evidence: h1 to h3

Checks: 33 failed, 33 passed, 3 not applicable.
