Our browser made a total of 58 requests to load all elements on the main page. We found that 55% of them (32 requests) were addressed to the original Datasheet.support, 10% (6 requests) were made to Fastly.jsdelivr.net and 7% (4 requests) were made to Googletagmanager.com. The less responsive or slowest element that took the longest time to load (204 ms) belongs to the original domain Datasheet.support.

Page Optimization Overview & Recommendations

Page size can be reduced by 80.2 kB (4%)

Content Size

1.9 MB

After Optimization

1.8 MB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Datasheet.support main page is 1.9 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. 60% of websites need less resources to load. Images take 1.6 MB which makes up the majority of the site volume.

HTML Optimization

-79%

Potential reduce by 28.9 kB

  • Original 36.4 kB
  • After minification 36.4 kB
  • After compression 7.5 kB

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 28.9 kB or 79% of the original size.

Image Optimization

-3%

Potential reduce by 49.9 kB

  • Original 1.6 MB
  • After minification 1.5 MB

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. Datasheet images are well optimized though.

JavaScript Optimization

-0%

Potential reduce by 1.1 kB

  • Original 242.8 kB
  • After minification 242.8 kB
  • After compression 241.7 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. This website has mostly compressed JavaScripts.

CSS Optimization

-12%

Potential reduce by 301 B

  • Original 2.5 kB
  • After minification 2.5 kB
  • After compression 2.2 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. Datasheet.support needs all CSS files to be minified and compressed as it can save up to 301 B or 12% of the original size.

Requests Breakdown

Number of requests can be reduced by 16 (33%)

Requests Now

  • AJAX
  • Images
  • JavaScript
  • CSS

The browser has sent 48 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Datasheet. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 14 to 1 for JavaScripts and from 4 to 1 for CSS and as a result speed up the page load time.

  • Encoding

    UTF-8

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Datasheet.support can be misinterpreted by Google and other search engines. Our service has detected that English is used on the page, and it matches the claimed language. Our system also found out that Datasheet.support 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.

Social Sharing Optimization

Open Graph description is not detected on the main page of Datasheet. 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:
