Why You Need a CDN for Your Website
You only have a few seconds to make a first impression on a site visitor, so slow page speeds set you back immediately. Website caching and image compression are excellent ways to maintain fast load times, so why do we need a CDN? Physical hosting sites help “store” your host on a server. The server location affects load times regardless of your compression settings or caching. This effect is called latency. Naturally, when information has farther to go, it will take longer to get there. CDNs help reduce latency.
What is a CDN?
Content delivery networks, or CDNs, are a way to speed up your website. They are a network of servers built to store static content. By storing static page information in an easy-to-access location, your site can retrieve page information and deliver it to a browser blazingly fast.
How Does a CDN Work?
CDNs operate as a large network of servers meaning information can be stored anywhere in the world and relayed back to your website. Visitors anywhere can view your website faster. Your information is stored on a “host” server. As we mentioned earlier, the further away your visitor is, the longer the load times. This latency is due to “hops.” Hops refer to how often information needs to jump from server to server before being delivered to the visitor. The more hops, the longer the load time. Choosing the location for your host server is important because it will play a major role in your page load times.
A CDN can help your website perform better in every way, including sales. Visitors are more likely to have a better user experience when a site loads quickly and easily navigates from page to page. When you’re trying to convert leads to sales with website content, an engaging website is vital.
CDNs also employ a caching system much like your server. Site information moves from your server to the CDN freeing up bandwidth. On that note, a CDN is exactly that, a content delivery network. Utilizing the network helps handle large spikes in traffic since it can spread information over several servers.
Most importantly, CDNs are scalable. Your website will see user ebbs and flows, but ultimately, the goal is to grow your visits. When that happens, your server needs to be ready to handle the new traffic. Content delivery networks are a ready-made solution to make sure you don’t run into any kinks.
CDNs are becoming more and more popular for their versatility and speed enhancements. Just like with caching, a CDN reduces latency and load times. We know slow page speeds can kill your traffic and SEO. Every additional second of load time costs you potential sales and crucial visitors. Since the CDN stores much of the site’s information, page speeds go up exponentially.
One issue websites run into is a slow TTFB, or time to first byte. Without going too far into the weeds, this refers to how long it takes for your website to retrieve data for the browser request. Depending on the server and the data, your TTFB could have a negative impact on site performance. CDNs dramatically increase TTFB just by moving bits of information away from your server and onto the network. Shamrck’s website health check helps test for your time to first byte.

Caching is the quick and (sometimes) easy way to speed everything up. At a server-level, caching can be broken down into very technical terms, but for the average end-user, plugins like WP Rocket help take care of the work for you. Here are some ways to speed up your website with caching.
What is Cache?
A cache is a collection of items of the same type stored in a hidden or inaccessible place. In the software world, we refer to it all the time. Traditionally, when someone clicks into a web page, the site has to request information from the server, which sends the data back to the browser, and users see the end result. Caching speeds up your website by not requiring it to request page information every time someone visits.
Since most webpages contain headers, bodies, and footers, continually having to piece together every bit of information after each click is, understandably, time-consuming. The process slows down page load times since the server is processing so many requests at once.
Why is caching important for websites?
Caching saves much of the website’s information for a server, so it doesn’t have to handle requests for every part of a web page anymore. The cache stores files to a disk or RAM, making it easier to duplicate the information when requested. This process limits the amount of work going into loading and reloading webpages, making them load faster.
Since these repeat files are stored, caching reduces the stress on your server. A fast server equals faster page load times, which has a substantial impact on your SEO. But more on that in a minute. This process also speeds up the time to first byte (TTFB). Essentially, the TTFB is the time it takes for a browser to start to receive information from the server. A low TTFB is crucial to fast load times.
Server-level caching with a good host.
A good host will handle caching for you. There are generally four types of caching done at the server-level: Bytecode, Page, Object, and CDN. We can break these down one at a time to understand why each is essential and why utilizing a speedy server with a good host is vital.
- Bytecode: Bytecode cache deals with PHP code. PHP codes must be compiled into what’s known as a readable “opcode.” Once the opcode is in place, the server no longer needs to sift through the PHP to return browser requests.
- Page: Page caching refers to storing the entirety of the HTML from a webpage, so WordPress does not need to generate the page over and over. Most pages are static and evergreen, meaning they don’t change much. The server does not need to build the page for every click continually.
- Object: Object caching refers to storing database query information. Querying a database can be arduous and time-consuming for a server. Caching bits of data produced by a search means speeding up the page load times since there’s no need to query an entire database every time.
Server-level caching is crucial because a good host does all of this behind the scenes. Since page load times are vital to your website’s SEO, caching as much information as possible is paramount.
WordPress Caching with WP Rocket.
Sometimes we need to go further than our server-level caching. WordPress has mechanisms in place to replace or supplement caching strategies. You can use plugins to perform caching functions if you are self-hosting or using a shared host. There are dozens of plugins to choose from, but we recommend WP Rocket.
WP Rocket is exceptionally robust but simple to use. Developers will love the ability to play around inside the plugin, but we love that it is excellent for beginners who might feel overwhelmed quickly. The WP Rocket dashboard and settings are easy to set up and understand. The plugin also seamlessly works with eCommerce sites to make sure page load times are blazingly fast.
WP Rocket is a premium plugin offering different pricing plans, but given the usability and depth of the software, we recommend at least trying out the free trial.
How caching affects SEO
One of the largest hurdles websites face when trying to rank on Google is page load times. The Google search algorithms weigh load times heavily when ranking sites. This factor makes caching a must-have. Without caching, your server load speeds will deteriorate as your pages become more dynamic, and the servers have to request and report every line of code/image/etc. for every click.
The stress will be too much for your server, and page load times will be slow. Not only will that affect your SEO, but you’ll lose traffic almost immediately. No one wants to wait more than five to seven seconds on a website to load. For every second it takes until TTFB, your site slips slightly further in the rankings and becomes more invisible in searches.
Caching is crucial
Websites today are dynamic, loaded with images, and interactive modal windows. Ecommerce sites have tons of media, links, and walls of text. The sheer amount of data on each page is enough to strain any server. This is why caching is so vital. Without caching, servers can be spread too thin, and page load speeds can drop dramatically. The consequences can be disastrous.
Imagine your website is a store on the main street, but you start to open later in the day than other stores. So, the city moves your store to 3rd street. Search engines are no different. Search algorithms look for the “stores” that open early. Websites with fast speeds will outrank the slower ones, so make sure your site is as quick as possible. Don’t lose your place in the market because you didn’t apply some simple methods to make your website faster.
