Speeding up a slow website

A slow website creates frustration in users and decreases conversions, whether contacts or purchases
A slow loading time, in addition to making our brand perceived as unreliable, penalizes, in a direct way, the position in search results, Google and all other engines, reward the loading speed of websites

Site SEO is also penalized in an indirect way, causing us to lose visitors, page views, and stay on the site

Main causes of slowness

There are often many causes, lack of CDN, unoptimized images, uncompressed internal scripts, and incorrect web server configuration

CDN content delivery networks

CDNs are content delivery networks distributed around the world, which create a cache of website elements allowing them to be served quickly from points close to the user's connection
They are critical for those doing business online, especially abroad, a prime example being for the untentee in the U.S.
Instead of having to source content from across the ocean, he can rely on a distribution point a few miles away

Non-optimized images

People often upload images to the site from digital cameras, or other sources, without concern for how they will be displayed
Uploading a 5 Megapixel image and displaying it in a 480 x 320 pixel frame is unnecessary, slows down and wastes resources, weighing down the site and slowing down loading
Through compression and resizing, huge amounts of bandwidth and loading time can be saved by increasing Pagespeed results

Uncompressed scripts

Both Javascript and CSS can be compressed (Javascript and CSS minify) and combined to reduce download time, number of connections needed optimizing site speed

Server misconfiguration

This is more common than you might think, often gzip compression, PHP caches or the like are not enabled
In addition, web server response times are often very long, even longer than 2 seconds in major commercial hosting, (the 50€ year ones) making fast loading impossible

Tests and metrics

Excellent online tests are available to check the speed of one's website, certainly the best is Gtmetrix, which combines Google Pagespeed and Yslow

Acceleration results

Web server acceleration

There are web server modules, which allow most of these changes to be made automatically, increasing performance and dramatically reducing loading times

To ensure maximum performance and customer satisfaction, we develop cloud infrastructure and web servers tailored to accelerate the speed of websites, covering all aspects across the board, from backend optimization, to creating points of geographic presence, in regions with high strategic value
