2.6 MB
1.7 MB
In fact, the total size of Arduino-tutorial.de main page is 2.6 MB. This result falls beyond the top 1M of websites and identifies a large and not optimized web page that may take ages to load. 65% of websites need less resources to load. Images take 1.4 MB which makes up the majority of the site volume.
Potential reduce by 94.1 kB
HTML content can be minified and compressed by a website’s server. The most efficient way is to compress content using GZIP which reduces data amount travelling through the network between server and browser. HTML code on this page is well minified. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 94.1 kB or 81% of the original size.
Potential reduce by 45.5 kB
Image size optimization can help to speed up a website loading time. The chart above shows the difference between the size before and after optimization. Arduino Tutorial images are well optimized though.
Potential reduce by 329.5 kB
It’s better to minify JavaScript in order to improve website performance. The diagram shows the current total size of all JavaScript files against the prospective JavaScript size after its minification and compression. It is highly recommended that all JavaScript files should be compressed and minified as it can save up to 329.5 kB or 55% of the original size.
Potential reduce by 350.9 kB
CSS files minification is very important to reduce a web page rendering time. The faster CSS files can load, the earlier a page can be rendered. Arduino-tutorial.de needs all CSS files to be minified and compressed as it can save up to 350.9 kB or 83% of the original size.
Number of requests can be reduced by 42 (47%)
89

The browser has sent 89 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Arduino Tutorial. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 26 to 1 for JavaScripts and from 13 to 1 for CSS and as a result speed up the page load time.

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Arduino-tutorial.de can be misinterpreted by Google and other search engines. Our service has detected that German is used on the page, and it does not match the claimed English language. Our system also found out that Arduino-tutorial.de main page’s claimed encoding is utf-8. Use of this encoding format is the best practice as the main page visitors from all over the world won’t have any issues with symbol transcription.

Open Graph description is not detected on the main page of Arduino Tutorial. Lack of Open Graph description can be counter-productive for their social media presence, as such a description allows converting a website homepage (or other pages) into good-looking, rich and well-structured posts, when it is being shared on Facebook and other social media. For example, adding the following code snippet into HTML <head> tag will help to represent this web page correctly in social networks:
