Increasingly, you hear about web performance as criteria for search engine rankings. 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.
There are several factors that affect the performance of the site. Here we will cover the main 3: images, cache and Content Delivery Network (CDN).
Why is charging time important?
o optimize resources, Google robots spend a limited amount of time on each page, called a crawling budget. The more pages are optimized, the faster they will load and the better Google will track them.
Therefore, one of the keys to ensuring that the pages of your site are indexed and visited by Google is to present them as quickly as possible to Google crawlers.
1 – Optimize images
Images are the first factor that influences 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 images?
There are several tools and methods that allow you to optimize images. The first tip is “save images for the web” when creating images with Photoshop. This allows them to be automatically optimized and adapted to the Web. There are also online tools https://tinypng.com, for example to remove all unnecessary data that increases the weight of images.
By doing this, you dramatically decrease the charging time.
2 – Configure 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 requests from the server 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 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 to do so.
3 – Use CDN
Another important parameter that sites don’t use enough is CDN: Content Delivery Network. 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 away the user is from the server, the longer the load time will be. Through various servers, the CDN makes it possible to deliver cached pages from the closest server or servers to each visitor. Therefore, its static content is available in as many places in the world as possible. Another important parameter that sites don’t use enough is CDN: Content Delivery Network.
