Priority fixes for vikingrivercruises.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
Why it matters: A sitemap helps search engines find new and updated pages, especially on large or frequently updated sites.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
83% of Travel Bookings & Trip Planning peers do this. Limit: Only the standard location was requested, once, at the time of the check.
Guide: XML Sitemap Guide: Include Only URLs You Stand Behind
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 21 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
41% of Travel Bookings & Trip Planning peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 3 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 5 external scripts without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
44% of Travel Bookings & Trip Planning peers do this.
Guide: Control Third-Party Scripts Before They Control Your Page
Priority 4 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 21 images and none used loading="lazy".
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
62% of Travel Bookings & Trip Planning peers do this.
