Fix plan
Written by gpt-4o-mini from the scan findingsYour site has a solid health score, but there are a few areas for improvement, particularly around title tags, meta descriptions, and asset optimization. Prioritize these fixes for better performance.
- 1
Fix Title Issues
Why: Seven pages have duplicate or long titles, affecting SEO.
How: Give each affected page a unique title of 60 characters or less.
Checks: titles
- 2
Improve Meta Descriptions
Why: Eleven pages share meta descriptions, leading to poor SEO.
How: Create unique meta descriptions for the pages with issues, ensuring they're under 160 characters.
Checks: meta-descriptions
- 3
Resolve Redirect for Sitemap
Why: A redirect from the sitemap.xml could impact visibility.
How: Update or remove the 301 redirect to ensure search engines access the correct sitemap file.
Checks: redirects
- 4
Optimize Heavy Assets
Why: Ten assets are over 500 KB, slowing down page load.
How: Compress heavy assets such as images and stylesheets to improve performance.
Checks: heavy-assets
- 5
Update Sitemap Coverage
Why: Four crawled pages are missing from the sitemap, risking indexability.
How: Add the missing pages to the sitemap to ensure they're indexed.
Checks: sitemap-coverage

Security review
Written by gpt-4o-mini from 16 checks over the crawlThe website horizonheating.ca lacks critical security headers, which exposes it to potential risks such as interception and script injection. Immediate implementation of these headers and upgrading a vulnerable library are recommended to enhance security.
- 0 high
- 3 medium
- 1 low
- 1 info
- 1
Missing HTTP Strict Transport Security (HSTS)Medium
Why it matters: Without HSTS, visitors could be intercepted on their first request by typing the site address without HTTPS.
Fix: Implement HSTS by adding the header: Strict-Transport-Security: max-age=31536000; includeSubDomains.
Evidence: HTTP Strict Transport Security
- 2
Missing Content Security Policy (CSP)Medium
Why it matters: The absence of a CSP allows unrestricted loading of scripts and resources, increasing the risk of cross-site scripting attacks.
Fix: Add a CSP header: Content-Security-Policy: default-src 'self';.
Evidence: Content Security Policy
- 3
Vulnerable JavaScript Library DetectedMedium
Why it matters: jQuery 3.2.1 has known vulnerabilities that could be exploited under certain conditions.
Fix: Upgrade jQuery to version 3.5.0 or higher to mitigate risks.
Evidence: Vulnerable JavaScript libraries
- 4
Missing Referrer-PolicyLow
Why it matters: Without a Referrer-Policy, sensitive URL data may be sent to external sites a user visits.
Fix: Implement referrer policy by adding the header: Referrer-Policy: no-referrer.
Evidence: Referrer policy
- 5
Missing Permissions PolicyInfo
Why it matters: No Permissions-Policy limits potentially harmful browser features for scripts injected on the site.
Fix: Add the header: Permissions-Policy: geolocation=(), microphone=(), camera=();.
Evidence: Permissions policy

- FoundVulnerable JavaScript librariesMedium
1 library with published vulnerabilities: jQuery 3.2.1. Whether they are exploitable depends on how the site uses them, but each has a fixed release.
- jQuery 3.2.1 in https://horizonheating.ca/wp-content/plugins/gravityforms/js/placeholders.jquer…: CVE-2019-11358 (prototype pollution), CVE-2020-11022, CVE-2020-11023 (XSS via HTML passed to DOM methods); fixed in 3.5.0
- NoteThird-party scripts
Scripts run from 1 other domain without Subresource Integrity, so a compromise of any of them changes what runs on this site. (Tag managers and analytics rarely support SRI; a Content-Security-Policy that names these hosts is the usual control.)
- www.google.com (40 script tags)
- NoteSensitive paths in robots.txt
robots.txt lists 2 paths that look private. robots.txt is public and does not restrict access, so it doubles as a map for anyone probing the site; those paths need real access control.
- Disallow: /cgi-bin
- Disallow: /wp-admin/
