How this service works
Prüft am Objekt artikel den Befund vorhandene Meta-Beschreibung.
Output
Returns a validation finding (Befund) indicating whether a meta description is present on the targeted article object at the given URL, potentially scoped to a specific CSS selector element.
Example use cases
SEO audit for a blog article
“Can you check if this blog post has a meta description? The URL is https://mysite.de/blog/warum-ki-wichtig-ist — look at the main article element using the selector 'article.post-content'.”
Automated content QA before publishing
“Before we go live, check that https://news.example.com/aktuell/bericht-2024 has a meta description on the article section — the selector is 'div.article-body'.”
Monitoring meta tags on a competitor page
“Check if https://konkurrenz.de/produkte/uebersicht has a meta description present on the page — no specific selector needed, just check the whole page.”
Technical details
Endpoint
POSThttps://bau.halowerk.com/v1/pruef/bau/beschreibung/artikel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically validate the presence of a meta description tag on an article or content object on a given public URL, particularly for SEO auditing or content quality checks on German-language or European web properties. Prefer this over generic HTML scrapers when you want a structured pass/fail finding rather than raw HTML extraction.
Side effects
- URL is not publicly accessible or returns non-200 status
- CSS selector matches zero elements — first matching element used as fallback
- Malformed or overly long URL (exceeds 2048 characters) causes rejection
- Page blocks crawlers or returns empty body
- Invalid CSS selector syntax causes parsing failure
