3 tips to optimize the performance of your website

More and more, you hear about web performance as search engine ranking criteria. This factor combines several indicators that allow Google robots to judge if your site is fast and combine it with other factors to determine the positions of your pages.

Several factors affect site performance. Here we will cover the 3 main ones: images, cache and Content Delivery Network (CDN).

Why is charging time important?

To optimize resources, Google bots spend a limited amount of time on each page, called the crawl budget. The more the pages are optimized, the faster they will load and the better Google will follow them.

Therefore, one of the keys to ensuring that the pages on your site are indexed and visited by Google is to present them as quickly as possible to Google robots.

1 – Optimize images

Images are the number one factor influencing the loading time of websites. Many sites neglect this essential aspect for SEO and content themselves with inserting images without any optimization. It’s not uncommon to see people uploading photos directly from their digital cameras to their sites, even if they’re several megabytes in size. However, there are simple tricks to fix it.

How to optimize images?

There are several tools and methods that allow you to optimize images. The first tip is to “save images for the web” when creating images with Photoshop. This allows them to be automatically optimized and web-friendly. There are also online tools https://tinypng.com, for example to remove all unnecessary data that increases the weight of the images.

By doing this, you significantly reduce the charging time.

2 – Configure the cache

What is the cache?

You can store the static elements of your client-side pages. For example: the logo. This reduces the number of server requests to display your pages.

The principle is simple: during the first visit to the page, the static files are stored on the user’s computer. On the next visit, the page is displayed almost instantly because there are fewer requests to make on the server. This is a powerful way to optimize charging time.

How to configure the browser cache system?

If your site works with a CMS like WordPress, there are several extensions that allow you to create a cache system: W3 Total Cache or WP rocket for example.

If your site was created with its own language. Contact your webmaster for this.

3 – Use CDN

Another important parameter that sites do not use enough is the CDN: Content Delivery Network. The CDN works like this: Instead of loading all the elements of a page from a single server, we go through a network of servers located in many data centers around the world. Why ? The further the user is from the server, the longer the loading time will be. Through different servers, the CDN makes it possible to deliver cached pages to each visitor from the closest server(s). Therefore, its static content is available in as many places around the world as possible. Another important parameter that sites do not use enough is the CDN: Content Delivery Network.
