Some would say Website Development is an easy task, but is it easy to Optimize a developed Website. Well Yes. If you follow certain steps. WebAnalyzer lets you find major threats in your website. These threats, if not fixed will let your website page load time increase and making business leads go down. No customer wants to wait for the page to load forever. WebAnalyzer's Major Threat's section is categorized in four Major Threats. FrontEnd Unoptimized CSS Threats , Unhandled JavaScript bottlenecks, Bad Server Configuration and High Image Rendring. Lets discuss them in detail


FrontEnd Unoptimized CSS Threat


Everyone must follow the following rules and best practices while implementing CSS in Any Websites. CSS documents are render-blocking resources: they should be stacked and processed before rendering the page. Web pages which have unwanted large styles take longer to render.

Below is a list of Factors to Be Taken Care While Deploying Stylesheets:

  • Use of Preload/Preconnect/Prefetch
  • Restrict Use of @import
  • Restrict Use of !important
  • Restrict Use of CSS Expressions
  • Restrict StyleSheets Links in Body
  • Avoid Duplicate StyleSheets

Preload or prefetch in the link tag uses early fetch request to get the content. This will imply that these resources are fetched earlier and are less likely to block the page's first render, which ultimately will lead to better page performance.
The Import function in the CSS will dramatically affect the page load time as it is not in asycn function. Javascript is synchronous and single-threaded. !important declarations overrides the cascading nature of CSS and are frequently viewed as a hack. But like most things proposed to the CSS specifications,!important has a few reasonable applications.

Unhandled JavaScript bottlenecks


Check the Do's and Dont's for optimized JavaScript implementation in Any Websites. Delivering less JavaScript would take less time in network request calls, less spent decompressing code and less time parsing and executing this JavaScript.
Below is a list of Factors to Be Taken Care While Deploying JavaScript:

  • Make Ajax Response Cachable
  • Restrict Use of document.write
  • Restrict Use of Bad Plugins
  • Avoid POST for Ajax Calls
  • Restrict JS Src Above Body
  • Avoid Type="Text/Javascript" Attribute

Caching everything that can be cached is a nice way to optimised the web-page. Ajax has a way that allows this through their cache parameter providing a good performance gain.Caching must be always done by the library itself without any of the prior settings. The document.write() method basically writes a string of text to a DOM stream which is then further opened by document.open(). So, to put or add an extra content in our web pages, one should prefer Manupulating the DOM rather than than using document.write. While they are helpful but an oversized, unoptimised plugin will take minutes to process and ultimately takes the website down. So the backend developers should be careful while implementing useless plugins

Bad Server Configuration


A Server is the heart of Any applications. The one you can not compromise with. Server Performance standards play heavy role is how user experiences on any website. Follow and tune the server with the help of following points that cause disruptive downtime.

  • Avoiding Character Set With Meta-Tag
  • Less PageRedirection Count
  • Avoid E-Tag Status
  • Reduce Total Page Requests
  • Reduce DOM Size
  • Use GZIP Compression

Using character set in the meta-tags create nuisances in the browser rendering and the crawling search engines. These character-sets are used in order to find what should be shown on a web-page. Url Redirecting makes a web-page to load slower because requests conversion takes a lot of time from one url to other. Many websites suffers a lot of speed issues because of this. Avoding any redirects and keeping the original url will he If you do not use any redirects, you are serving your content significantly faster. Enitity tags are a way to determine  whether the component in the browsers's cache is matched against that of the backend server. That component can be either an image,css,scripts,stylesheets etc. Sending Etags everytime in the header takes a lot of time for the requests to process and corresponding status is sent back to the server. A sample ETag looks like this:

HTTP/1.1 200 OK Last-Modified: Tue, 12 Dec 2006 03:03:59 GMT ETag: "10c24bc-4ab-457e1c1f" Content-Length: 12195

High Image Rendering


Optimizing your website pictures offers you one more opportunity  to upgrade your user experience. While adding an image to your WebPage is a simple task, it takes a little more work to get the full optimization for that image.
Improved images are additionally a vital piece of your on-page SEO and they help supplement your other SEO endeavors.

  • Avoid Broken Images
  • Image Optimization
  • Thumbnails And Images Count
  • Image Resizing At Browser End

Some image source files have the broken image links,and these links are found when the URL is wrong. A Broken image created a wasted response from an HTTP request, which increases the page load time. Now, the browser tries to download that image which is not available meaning our web page spends more time trying to download the image ultimately slowing down the website. Also the user-experience will take a hit with those broken images. Broken images are one of the biggest drains on the page load time. With WebAnalyzer one can check for broken image links and manually removing them from the websites. Handling broken images on the image server is the best way as it will handle for all types of image formats. Image optimization is a major issue that threatens the webpage latency rate and full page loading. Nowadays, images are becoming more and more render blocking sources that are a major issue in any webpage. WebAnalyzer has factors listed out the parameters required to optimize the images.
