Our browser made a total of 94 requests to load all elements on the main page. We found that 31% of them (29 requests) were addressed to the original Scipy.in, 16% (15 requests) were made to Google.com and 14% (13 requests) were made to Maps.googleapis.com. The less responsive or slowest element that took the longest time to load (1.1 sec) belongs to the original domain Scipy.in.

Page Optimization Overview & Recommendations

Page size can be reduced by 1.2 MB (51%)

Content Size

2.3 MB

After Optimization

1.1 MB

  • HTML
  • Images
  • JavaScript
  • CSS

In fact, the total size of Scipy.in main page is 2.3 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. Javascripts take 1.1 MB which makes up the majority of the site volume.

HTML Optimization

-79%

Potential reduce by 56.4 kB

  • Original 71.0 kB
  • After minification 57.0 kB
  • After compression 14.6 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. This page needs HTML code to be minified as it can gain 14.0 kB, which is 20% of the original size. It is highly recommended that content of this web page should be compressed using GZIP, as it can save up to 56.4 kB or 79% of the original size.

Image Optimization

-4%

Potential reduce by 31.4 kB

  • Original 698.9 kB
  • After minification 667.5 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. Sci Py images are well optimized though.

JavaScript Optimization

-66%

Potential reduce by 709.1 kB

  • Original 1.1 MB
  • After minification 1.1 MB
  • After compression 365.4 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 709.1 kB or 66% of the original size.

CSS Optimization

-84%

Potential reduce by 377.7 kB

  • Original 452.1 kB
  • After minification 424.2 kB
  • After compression 74.4 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. Scipy.in needs all CSS files to be minified and compressed as it can save up to 377.7 kB or 84% of the original size.

Requests Breakdown

Number of requests can be reduced by 37 (45%)

Requests Now

  • AJAX
  • Images
  • JavaScript
  • CSS

The browser has sent 83 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Sci Py. 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 and Encoding

  • Language Detected

    EN

  • Language Claimed

    EN

  • Encoding

    UTF-8

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Scipy.in 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 Scipy.in 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

scipy.in

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