Depending on the competitive nature of your industry, a CDN alone might not be sufficient to break onto the first page of Google. Worse still, there are paid CDN service that will cost you both time and money and still won’t meet your needs. You should consider the following factors when choosing the right CDN for your website:

Define why you need a CDN

If you do no run of a large corporation or are on a tighter budget, you can still go with the best CDN hosting provider that offers a free CDN. These can be limiting for certain businesses however, so check if those same providers offer reasonably priced pro plans with full features.

Define What Kind of Features You Need

Consider the main features, such as web filtering, smart image optimization, user interface, SEO benefits, cache control, SSL coverage, integration with WordPress (if you use it), and how easy it is to set up a CDN. If you go with a fully-managed provider, they will install everything for you.

Pay Attention to Performance

Make sure to check if a CDN performs in delivering quick page load times and if it supports both static and dynamic content.

Check out Customer Support and Pricing Plans

The best CDN providers offer exceptional customer support and affordable prices. Check if your CDN provider offers multi-language support, for example.

Consider if PoP Locations are Close to Your Audience

Pay close attention to where your potential customers are located because choosing a CDN that manages PoP locations close to them significantly impacts the overall CDN performance.

Trust and Safety

Benefits of Using a CDN

Reduced Latency & Improved Speed

Latency refers to the time data travels from the server to the user’s device. The distance between the server and the user significantly affects latency.

A Content Delivery Network reduces latency by caching content (temporarily storing copies of your website files) on a network server closer to the user. This simply results in a faster page load time.

Lower Bandwidth Consumption Leads to Cost Savings

Simply put, when your network’s bandwidth usage is high, your network performance can easily drop. This means that to keep your site up, you have to upgrade to a plan with more resources, and your web hosting costs can significantly increase.

However, that should not be the case if you take advantage of CDN servers because they can help you maintain better control of web hosting costs. They can reduce bandwidth demands on origin servers, which means that website traffic is split over multiple CDN edge servers.

Improved SEO Rankings & Website Visibility

If you have basic SEO knowledge, you already know that page speed is essential to Google’s algorithm. Efficient content delivery, page speed, and overall user experience are vital for your SEO rankings.

Since CDNs distribute your content through server proxies, your website will likely rank higher organically. Your improved SEO rankings will also increase your website’s visibility, which will help you reach new customers and boost revenue.

Enhanced Site’s Security

A CDN provides an added layer of security by offering services such as blocking features for DDoS protection, firewalls, and DNS monitoring. In other words, a CDN ensures balanced traffic loads and secure transcription.

Keep in mind that free CDN plans offer limited security features. With a fully managed provider, maintenance and website security come stock standard with your fully managed hosting plans. You should also get an SSL certificate to enhance your site’s security, and a quality provider will give you one for free with every domain name you buy.

Increased Customer-Loyalty

Asides from the aforementioned technical benefits, an additional practical element is an improved user experience. A CDN and an SSL certificate might not bring in more customers, but not having them will surely lead to higher visitor bounce rates due to slower page load times and warning pop-ups about site security.

Drawbacks of Using a CDN

Issues With Implementation

Some CDNs are not as simple to set up, meaning that you may require a developer when integrating a CDN into your website. A fully-managed provider however will take care of this for you, saving you both time and a potential expense in hiring a developer.

Extra Cost

A paid CDN naturally incurs additional charges though the cost will depend on the number of visitors, website resources, and the number of requests your CDN gets. As mentioned before however, this cost can be offset or even negated entirely by not having to upgrade to a hosting plan with more local resources.

Mismatch Between Server’s Location

Pay special attention to your audience location. This is important because if CDN servers are located near them, they will be much more efficient in delivering content faster. For example, if you have a local-only Seattle-based business, you don’t need a CDN located in Europe and Asia.

Customer Support Constraints

First and foremost, you won’t experience customer support issues if your web hosting service can optimize and fine-tune your CDN hosting setup for the highest possible speed and efficiency. Unlimited managed support is, therefore, a must if you want to save your time and energy.
