Low impact · weight 4 · worth up to 1.3 points of the total score
A JSON-LD block with a trailing comma or an unescaped quote is discarded whole. The rich result it was meant to earn silently never appears, and nothing in the page looks broken.
Fix the JSON syntax in the failing block, then confirm it in Google's Rich Results Test.

Open Graph tags are present
Open Graph decides what a link to this page looks like when someone shares it on Slack, WhatsApp, LinkedIn, or Facebook. Missing tags turn a share into a bare URL with no image, which measurably costs clicks.
hreflang alternates are absolute URLs
Google requires fully qualified URLs in hreflang annotations. Relative hrefs are ignored without any error, so the language targeting simply never happens and nobody notices.
Site has a reachable XML sitemap
A sitemap is the list of pages a site wants crawled. Without one Google finds pages only by following links, so new or thinly linked pages can take weeks to be discovered.
Title and H1 are related but not identical
The title is written for the search results page and the H1 for the visitor who already clicked. Making them byte-identical wastes a second chance to describe the page, while sharing no vocabulary at all suggests the two disagree about the topic.
