Serverless HTML Code

For over a decade, WordPress dominated the internet. The promise of building websites by dragging blocks and installing plugins was tempting. However, the cost of this "convenience" arrived in the form of bloated, slow websites that are extremely vulnerable to cyber attacks. Google noticed this and changed the game with Core Web Vitals.

The Mathematics of Abandonment

Google's studies reveal a harsh reality: if your site takes more than 3 seconds to load on 3G/4G, over 53% of visitors close the tab and head to a competitor. Core Web Vitals measure precise metrics such as LCP (Largest Contentful Paint) and CLS (Cumulative Layout Shift).

"A page with 40 active plugins cannot trick Google's performance algorithm. Slowness destroys your ranking."

The Solution: Serverless and Headless Architectures

At MR Marketing, our web engineering has adopted the modern standard. We separate the website's "brain" from its visual layer. Using static technologies (JAMstack) or Meta-frameworks, the site is pre-generated and delivered via global Content Delivery Networks (CDNs) in milliseconds.

The migration requires code refactoring, but the end result is a shielded digital asset that is lightning-fast and organically prioritized by search engines.

Is your current site hurting your sales?

We perform deep Core Web Vitals audits and refactor slow platforms into high-performance code.
