Pagespeed, the loading time of a website, is an issue that is once again gaining in importance in the development and operation of websites. Although the speed of standard internet connections has steadily increased, web applications are tending to become more complex and extensive: content management systems with complete CSS and JavaScript frameworks, elaborate image material and multimedia functions continue to stretch bandwidths to the limit.
Therefore, the optimisation of loading times is a customer service in the sense of good usability of one's own online offer. And last but not least, Google, as probably the most important search engine provider, never tires of emphasising the importance of short loading times for the ranking in the search results.
How fast is my website?
Die Angebote zur Messung von Online-Ladezeiten ist groß und unübersichtlich. Die reine Zeitangabe, in der meine Homepage geladen wird, ist zudem erst einmal wenig aussagekräftig – wichtiger ist ja eine Einschätzung zum Optimierungsgrad dazu: Ist die Ladezeit “gut” oder “schlecht”, ist da noch Raum für Verbesserungen?
Wir wollen im Folgenden ein Tool vorstellen, das mit einem Mausklick umfangreich und dabei übersichtlich Performance-Angaben und konkrete Verbesserungsmöglichkeiten zugänglich macht. Es handelt sich dabei um ein Browser-Addon mit dem Namen “All-In-One PageSpeed Test“, das für Mozilla Firefox wie auch Google Chrome verfügbar ist. Nach Installation stellt das Addon ein Symbol im Browserfenster, das bei Klick für die gerade im Browser angezeigte Seite in drei neuen Tabs Pagespeed reports from Yellow Lab Tools, from Google's Pagespeed Insights and from GTmetrix displays.
These three services each give an overall rating between 0 and 100 and list the criteria evaluated in detail.
They focus on different aspects and can therefore arrive at different ratings for a website. However, this is what makes the compilation of these offers so attractive, as the results obtained complement each other very well and provide a comprehensive overall picture of performance. All offers also provide detailed information and in some cases specific instructions on how optimisations can be implemented and how important or promising the proposed improvements are.
This makes it quick and easy to assess the performance of one's own web presence, to receive suggestions for optimisation and to monitor the success of implemented optimisation steps through further tests.
