Quick Wins
High-impact, low-effort fixes, ranked by what this scan actually found.
- Set font-display: swap on the web fonts — Text is readable in a fallback face from the first paint instead of being hidden.
- Send a Referrer-Policy header — Internal URLs stop leaking to third-party sites.
- Add alt text to the images that are missing it — Search engines can index the images and screen-reader users learn what they show.
- Send a Strict-Transport-Security header — Browsers refuse to fall back to plain HTTP for this domain.
- Send an X-Frame-Options header — The site cannot be framed for click-jacking.
- Add the responsive viewport meta tag — The layout adapts to phones instead of being zoomed out.
What the site checks found
- Low — SEO — Sitemap URLs pointing at a different domain: 8 — they will be ignored.
- Low — SEO — No entry in the sitemap carries a lastmod date, so crawlers cannot tell which pages have changed since they last read them.
- Medium — SEO — 6 hreflang links are not confirmed by a link back from the other language: /howyoutubeworks/ → /intl/he_ALL/howyoutubeworks/ (iw), /howyoutubeworks/ → /intl/ALL_lt/howyoutubeworks/ (lt), /howyoutubeworks/ → /intl/ALL_ee/howyoutubeworks/ (et). Google ignores one-way pairs.
- Medium — SEO — 1 hreflang alternates name a different canonical, so the listed version is not the one in the index: /howyoutubeworks/ → /intl/he_ALL/howyoutubeworks/ (iw).
- Medium — SEO — Sitemap URLs answering with an error: 1 of 5 checked — the sitemap is sending crawlers at pages that are gone.
- Low — Security — The Content-Security-Policy allows 'unsafe-inline' or 'unsafe-eval', which is what a script injection needs.
- Low — Security — The Content-Security-Policy sets no default-src, base-uri, frame-ancestors, so those are left at the browser default.
- Low — Security — The zone is not signed with DNSSEC, so a forged DNS answer cannot be detected.
- Low — Links — Internal links that reach their page through a redirect: 6 of 9 checked.
- High — Privacy — The site loads Google Ads, Google Analytics, Google Tag Manager with no consent layer anywhere in the markup — under the GDPR and the ePrivacy Directive those tags need consent before they run.
