How a Fast and Secure Website Boosts Your Sales (+Real Examples)

Why might your website be losing thousands of pesos a month?

The speed and security of your website aren't technical details: they're decisive factors for your business. If your website loads slowly or doesn't inspire trust, your customers will leave with the competition. According to Google, 53% of mobile users abandon a page if it takes longer than 3 seconds to load. And if you don't use HTTPS, your site may be labeled “not secure” in modern browsers.

In this article, we explain why web speed and security are key to increasing your sales and how you can improve both aspects with the help of Vexus Agency, the best web development agency in Mexico.

What are Core Web Vitals and why do they matter?

Google introduced Core Web Vitals as part of its positioning algorithm. These indicators measure the user experience on your website:

• LCP (Largest Contentful Paint): measures how long it takes for the main content to load. The ideal is less than 2.5 seconds.
• INP (Interaction to Next Paint): measure the time it takes for your website to react when the user interacts.
• CLS (Cumulative Layout Shift): measures visual stability (prevents elements from moving abruptly).

If you don't optimize them, your website will be penalized in SEO and the user experience will be affected.
And the worst: you'll lose customers before they see what you're offering.

How does speed affect your conversions?

A slow web frustrates. It doesn't matter how good your product is or how creative your design is.

• An extra second of charging can reduce conversion by 7%
• 79% of users won't return if they have a bad experience on their first visit

Imagine losing 7 out of every 100 sales... just because you don't optimize your website.

Keys to improving the performance of your website

1. Image optimization

Loading heavy images slows down your website. Convert them to WebP, use Lazy Loading (deferred loading) and compressing them reduces weight without losing quality.

2. Minimize CSS and JavaScript files

Eliminate unnecessary code, group and minify files. This dramatically improves the initial charge time.

3. Premium hosting

Many sites in Mexico use cheap shared hosting which affects their performance. At Vexus Agency we use optimized hosting with CDN so that your website loads quickly from any city in the country.

4. HTTPS required

Beyond the little green padlock, having HTTPS improves your SEO and gives you confidence. Google considers it a ranking factor, and users are wary if they see an “unsafe” site.

Security: Beyond the padlock

Attacks on small sites have increased: malware, data theft, and DDoS attacks can put your business at risk.

Implement HTTPS, Firewalls, constant updates And backups is essential.
At Vexus, every site we deliver includes advanced security settings and constant monitoring.

Conclusion: Your site must be fast and secure

A beautiful design is not enough. If your site takes longer than 3 seconds to load or doesn't have HTTPS, you're losing customers every day.
But you can change it today.
