Our browser made a total of 70 requests to load all elements on the main page. We found that 1% of them (1 request) were addressed to the original Datasheetcatalog.com, 40% (28 requests) were made to Yagi-antennas.com and 11% (8 requests) were made to Pagead2.googlesyndication.com. The less responsive or slowest element that took the longest time to load (4.7 sec) relates to the external source Cdn.adhigh.net.

Page Optimization Overview & Recommendations

Page size can be reduced by 868.5 kB (59%)

Content Size

1.5 MB

After Optimization

606.6 kB

  • HTML
  • Images
  • JavaScript

In fact, the total size of Datasheetcatalog.com main page is 1.5 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. 50% of websites need less resources to load. Javascripts take 1.2 MB which makes up the majority of the site volume.

HTML Optimization

-82%

Potential reduce by 69.5 kB

  • Original 85.0 kB
  • After minification 84.5 kB
  • After compression 15.5 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 69.5 kB or 82% of the original size.

Image Optimization

-4%

Potential reduce by 9.4 kB

  • Original 221.4 kB
  • After minification 212.0 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. Datasheet Catalog images are well optimized though.

JavaScript Optimization

-68%

Potential reduce by 789.6 kB

  • Original 1.2 MB
  • After minification 1.2 MB
  • After compression 379.1 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 789.6 kB or 68% of the original size.

Requests Breakdown

Number of requests can be reduced by 39 (57%)

  • AJAX
  • Images
  • JavaScript

The browser has sent 69 CSS, Javascripts, AJAX and image requests in order to completely render the main page of Datasheet Catalog. We recommend that multiple CSS and JavaScript files should be merged into one by each type, as it can help reduce assets requests from 24 to 1 for JavaScripts and as a result speed up the page load time.

Language and Encoding

  • Language Detected

    N/A

  • Encoding

    ISO-8859-2

Language claimed in HTML meta tag should match the language actually used on the web page. Otherwise Datasheetcatalog.com can be misinterpreted by Google and other search engines. Unfortunately we cannot identify language used on the page (probably there is a mix of languages, too little text or something else) and no language is claimed in <html> or <meta> tags either. Our system also found out that Datasheetcatalog.com main page’s claimed encoding is iso-8859-2. Changing it to UTF-8 can be a good choice, as this format is commonly used for encoding all over the web and thus their visitors won’t have any troubles with symbol transcription or reading.

Social Sharing Optimization

datasheetcatalog.com

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