REVIEW
Sitemap exists but no <lastmod> entries
Info::
Sitemap has no <lastmod> entries
Without lastmod, Google can't tell which URLs have changed since the last crawl -- it falls back to crawling everything periodically. Adding lastmod (date or ISO 8601 timestamp) on each <url> entry signals freshness so the crawler prioritizes recently-modified pages.

    Article

    Page reads as an article (long body + headline) — add Article schema

    Eligible for top-stories carousel and Discover

Adding these recommended fields improves chances of getting Organization knowledge panel in search results.

Why this matters

Schema entity has required fields but could add recommended ones for richer SERP layouts (star ratings, prices, etc.).

Source: Google Search Central

Your WebSite structured data is missing required fields for Google's Sitelinks search box. Without these, the page won't qualify for rich results.

Why this matters

Schema entity missing required properties — Google's rich-result eligibility check fails; the schema is in source but never renders enhanced.

Info::
Title uses 2 different separator characters: |, -
The page title `Knihobot antikvariát online | vracíme knihy do oběhu - kniho...` uses multiple separator characters (|, -). Consistent separator use is a soft signal of careful editorial control; mixed separators usually mean the title was assembled from multiple template fragments (CMS title + brand + section) without a normalization step. Pick one separator (commonly `|`, `-`, or `:`) and stick with it across the whole site.
