A sitemap is a file that lists the pages on your website so search engines like Google can find and crawl them. It won’t make a site rank on its own, but it’s one of the simplest ways to make sure new and deep pages don’t get missed. Diib’s data shows the businesses that build websites for a living skip it more often than most.<\/p>\n\n\n\n
Diib looked at the most recent sitemap check for websites scanned in September 2026, counting only sites where the scan returned a clear result (sitemap found or not found).<\/p>\n\n\n\n
This is aggregated Diib data from a single month’s scan, so treat it as a snapshot rather than a trend. “Not detected” means Diib’s scan didn’t find a sitemap where search engines usually look for one. Some of these sites may have a sitemap in an unusual location, and a missing sitemap doesn’t by itself mean a site is struggling in search. The group also likely includes many freelancers and new studios whose own sites are still a work in progress.<\/p>\n\n\n\n
Still, a web designer’s own site is often the first sample of their work a prospect sees, and the gap is easy to close. Most website builders and content management systems can generate a sitemap automatically once the setting is turned on.<\/p>\n","protected":false},"excerpt":{"rendered":"
