Website-Check mit kostenlosen Online-Tools

Website-Check mit kostenlosen Online-Tools

Ich sehe so viele fehlerhafte Websites. Einfache Fehler, wie ein unveränderter Slug auf der Beispielseite oder ein unveränderter Untertitel „Just another WordPress website“. Und es geht weiter mit kaputten Links, fehlenden „Skip to content“-Links, fehlenden Farbkontrasten, etc. – Es gibt sehr viel zu tun und zu überprüfen. Aber hey, dafür haben wir ja Computer und Skriptsprachen! Es gibt viele kostenlose Tools und Hilfsmittel da draußen. Wir brauchen nur 1 Stunde, um eine Website direkt nach dem Start zu prüfen (die Korrektur kann auch länger dauern …). Qualitätssicherung ist wichtig, auch wenn du nur ein kleiner Freelancer bist.
