9 Factors that Affect Your Website Speed

Website Speed Factors

Website speed is a critical element for your website’s success. A fast website generates more money, reduces bounce rate, generates more clicks, ensures better ranking in organic search, increases conversions.

Page load speed is considered one of the major ranking factors by Google. Over the last few years, with devices becoming faster, Page load time has become very critical to the success of a website.

There are a number of sites offering site speed tests such as Pingdom and Gmetrix, so finding out how fast your site is won’t be difficult.

To save you some time to find and fix the issues we put together a post for the factors that affect your website speed.

Top 9 Factors that Affect Your Website Speed

Too Many Plugins

Using as few plugins as possible is an effective way to maintain a fast website. Plugins are made of PHP code and add functionality and database queries. When the amount of plugin increases, the speed of your website goes down. More plugins also mean more bugs and potentially more security holes. Even if you don’t actively use a plugin, the plugin code/CSS is still loaded and this affects your website speed.

Not Caching Your Site

Caching your site helps improve page load times significantly for returning visitors. When you have caching enabled, your web page will save its static files, like images and HTML documents, in temporary files on the visitor’s computer.

Popular content management systems like WordPress and Drupal will have static caching features that convert dynamically generated pages to static HTML files.

GZIP Compression

Gzip is a simple method for compressing your website’s files to save bandwidth and speed up page load times. Gzip works by compressing your files into a zip file, which is faster for the user’s browser to load. The user’s browser then unzips the file and shows the content. This method of transmitting content from the server to the browser is far more efficient and saves a lot of time.

You can enable Gzip by simply adding the following code into your .htaccess file:

# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

 To check whether Gzip is enabled or working properly on your site, you can use Gziptest.com.

Content Delivery Network

CDNs are data centers spread across the globe, where you can store cached copies of your website. When someone tries to access it, they’ll get sent to the nearest data center, which in turn means less strain on your servers and better overall loading times for your visitors.

Because the bandwidth is spread across so many different servers, it reduces the load on any single server.

Optimize your images

Good quality images and other visual elements are important for SEO and usability. Image optimization is the act of decreasing file size without losing quality. You can optimize your images in Photoshop or directly on your website.

Multiple HTTP Requests

HTTP (HyperText Transfer Protocol), is the method to which browsers and servers communicate with each other over the Internet.

When a web page loads, it makes many HTTP Requests, which will usually consist of: images, stylesheets (CSS), scripts, videos, etc. Each image, stylesheet and script file will make a separate request to a server for the information.

Combining external JavaScripts into 1 file and external CSS stylesheets into 1 file reduces the number of HTTP requests and improves overall response times.

Minify HTML, CSS, and JavaScript

Your website is using a lot of files where the majority of them are HTML, CSS, and JS. These files contain tons of codes that are auto-generated or written by a developer. Minification refers to the process of removing unnecessary or redundant data without affecting how the resource is processed by the browser.

It’s one of the main methods used to reduce load times and bandwidth usage on websites.

Too Many Redirects

Each time a page redirects to another one, a user has to wait for the HTTP request-response cycle to complete. This increases the amount of time the website takes to load. Every redirect adds an extra network roundtrip for the visitor.

Time spent on redirect is most noticeable on mobile devices, especially since they tend to use slower networks.

Server response time

The Time to First Byte is the amount of time it takes after the client sends an HTTP GET request to receive the first byte of the requested resource from the server. According to WebPageTest.org, Time to First Byte is the time it takes for the browser to wait for the first byte of a requested resource to be received after the DNS lookup and connection time. So TTFB represents the amount of time it takes for the server to respond and build the web page.

A website with a higher TTFB can frustrate its visitors. According to Google, your website’s TTFB should be 200 milliseconds or less.
