Seven Website Content Optimization Tools and Methods You Should Start Using

Given that most websites today exceed two megabytes, content optimization is more important than ever. This is particularly true for mobile users who may experience sluggish cellular data speeds due to network limitations or data throttling. As websites grow in size and complexity, developers need to be aware of content optimization tools and methods that help them improve website performance.

When it comes to optimizing website content, there are plenty of tools in the developer’s toolbox, including paid services and simple methods that quickly improve page speed.

And when you find out more, check out this list of options to consider that will help you make your site a lot faster.

1. A Content Delivery Network

CDNs (content delivery networks) make your site more readily available to visitors from around the world by serving content from multiple locations.

A CDN uses a network of synchronized local servers (edge servers) that decrease the physical distance each client web request travels, making your site faster to load. For instance, if a New York user’s request is answered by a CDN server located in New York, the round trip and subsequent data downloads are much quicker than serving from your data center in London.

As an added bonus, the CDN service also provides added resilience. If your primary data center goes offline, requests for static content will continue to be served by the content delivery network’s edge sites.

2. HTTP Reverse Proxies (Web Application Accelerators)

Similar to a CDN, web application accelerators provide a localized caching function to increase the speed with which the content is loaded. But where CDN edge servers are best suited for static content, HTTP reverse proxies are designed to serve dynamic content.

As with CDNs, content is served to users from their nearest edge server, reducing the roundtrip time for each request. Our tests with the Varnish Cache system realized page load time savings of more than 10%.

3. Gzip Compression (or similar)

‘Smaller file sizes equal faster network transfer times’ is a basic computing principle, so it makes sense to shrink the size of your webpages and assets as much as possible.

The first step is to optimize web content, the second to compress it. Using gzip (available in popular web servers like Apache and Nginx as standard) you can compress webpages on-the-fly, transfer the zipped archive to the client’s browser, and re-assemble once received.

Compressing content using gzip is nearly 66% faster than requesting and downloading “raw” assets. Just make sure to include the Vary HTTP response header to ensure CDNs serve compressed content correctly.

4. HTTP/2

Released back in 2015, HTTP/2 is only used by 35.5% of the top 10 million websites (as of April 2019). There is a 64.5% chance your site is not using the HTTP/2.

One of the primary design considerations for HTTP/2 was to reduce data latency to improve page load speeds. The updated protocol uses data compression on HTTP headers and multiplexes multiple requests over a single TCP connection for instance. A new HTTP/2 Server Push functionality allows you to preemptively send resources to a compliant browser too, so that linked resources like JavaScript and CSS files are downloaded as soon as the parent HTML page is requested. And because HTTP/2 is fully backward compatible with HTTP1.1, there is no reason to omit it from your website optimization strategy.

5. Code Minifiers

Since web content is not typically powered by compiled code, the quality of your scripts and code is super important. CSS and JavaScript files can have a significant effect on page load time—particularly when they need to be downloaded and applied before the rest of the page has finished loading.

Minification focuses on getting rid of unnecessary characters from code, including white space, new line characters, comments, and others which aren’t required to execute the code. This technique reduces the overall size of the page without changing any of the functionalities.

6. Browser Cache

Browser cache is also an important part of your website optimization strategy. By leveraging browser cache on your user’s computer, you can improve the performance of subsequent pages your website visitor lands on.

Items stored in the browser cache can be retrieved locally for future website requests. This means that common recurring elements like your logo are called from the cache, rather than making a slower request to your website server.

7. Web Performance Monitoring

Without accurate metrics to refer to, your content optimization strategy is just a “best guess” exercise. You need a reliable way to assess which improvements work and monitor how web performance changes over time.

A website monitoring solution will give you an overview of what most affects web performance in your case, helping you make informed decisions on content optimization. You can set up website status so that the correct person gets notified as soon as there’s an outage, or other website issues happen. And to analyze how performance affects your users, you can use synthetic monitoring as well as real user monitoring.

Enhancing Your Strategy With Content Optimization Tools

The tools outlined here are just enough to get started with optimizing web content. They will help you establish a strongly performing website and provide a platform from which to continue shaving additional hundredths of a second off every resource request.
