3 tips to optimize the performance of your site

More and more, you hear about web performance as criteria for positioning on search engines. This factor combines several indicators that allow Google robots to judge whether your site is fast and to combine it with other factors to determine the positions of your pages.
There are several factors that impact site performance. We will deal here with the 3 main ones: images, cache, and the Content Delivery Network (CDN).

Why is loading time important?

To optimize resources, Google robots spend a limited amount of time on each page, it's called a crawl budget. The more pages are optimized, the faster they are loaded and the better Google will crawl them.
One of the keys to ensuring that the pages of your site are indexed and visited by Google is, therefore, to present them as quickly as possible to Google crawlers.

Optimize images

Images are the first factor influencing the loading time of websites. Many sites neglect this essential aspect for SEO and are content to insert images without any optimization. It is not uncommon to see people upload photos directly from their digital cameras to their sites, even if they weigh several megabytes. Still, there are simple tips to fix it.
How to optimize the images?
There are several tools and methods that allow you to optimize images. The first tip is "to save images for the web" when you create visuals with Photoshop. This allows them to be optimized automatically and adapted to the Web. There are also online tools https://tinypng.com for example to delete all the unnecessary data which increases the weight of the images.
Just by doing this, you significantly reduce your loading time.

Configure the cache

What is the cache?
You can store the static elements of your pages on the client-side. 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. It is a powerful way to optimize loading time.
How to set up the browser cache system?
If your site works with a CMS like WordPress, there are several extensions allowing you to create a cache system: W3 Total Cache or WP rocket for example.
If your site was created with a house language. Contact your webmaster to have it done.
