Structural Issues
Structural issues are problems with the fundamental technical scaffolding of a page — the declarations and directives in the document head that tell browsers and search engines how to interpret and render the page. Missing charset declarations cause encoding problems; missing viewport tags break mobile rendering; legacy AJAX crawling tags create confusion with deprecated crawl protocols; and soft 404s mislead search engines about whether a page actually contains content. All four are fixable at the template level.
No <meta charset> in <head> — browsers must guess character encoding.
No viewport meta tag — mobile browsers render at desktop width and scale down.
Deprecated <meta name="fragment"> tag found — the crawl protocol it references no longer exists.
Returns HTTP 200 but content signals a "not found" or empty state.
