Building a website requires more than just an attractive design. The core factor lies in an optimized technical infrastructure. In this article, Connect Tech shares a professional website checklist for businesses. This solution helps businesses optimize the operational performance of their websites.

Infrastructure Standards and Core Web Vitals Optimization

Server Response Time (TTFB)

The server response time (TTFB) should be under 0.2 seconds. High-quality hosting infrastructure helps data load faster. Businesses should prioritize Hosting or VPS services with servers located in Vietnam. This minimizes network latency for domestic users.

Optimizing the Three Core Web Vitals Metrics

Google evaluates page experience through three key metrics. The first is LCP, which measures the loading speed of the largest content element. The ideal LCP score should be under 2.5 seconds.

The next metric is INP, which measures responsiveness and interaction performance. Finally, CLS measures visual stability. The CLS score should remain below 0.1 to prevent layout shifts. Businesses should compress images using the WebP format. In addition, unnecessary CSS and JavaScript code should be optimized.

Technical SEO On-Page Checklist and Structured Data Schema

Implementing Schema Markup

Schema Markup helps Google bots better understand business entities. You should implement essential Schema types, including LocalBusiness, Organization, and Website. This increases the chance of displaying rich snippets in search results. Businesses can use structured data testing tools to validate schema implementation.

Managing Crawl Budget

The source code system should be configured with a properly structured robots.txt file. This file guides search engine bots to index important pages. Duplicate URLs should be handled using canonical tags. The sitemap.xml file should automatically update whenever new content is published. This helps optimize crawl budget for search engines.

 Security Standards and Mobile-First User Experience

Securing Data Through HTTPS Encryption

An SSL certificate is mandatory for business websites. HTTPS helps protect customer information. The system should be configured with a firewall to prevent dangerous cyberattacks. Automatic weekly data backups are an essential process that should never be overlooked.

Designing with a Mobile-First Approach

Google applies a mobile-first indexing algorithm. Website interfaces must be fully compatible with mobile devices. Interactive elements such as buttons should have a minimum size of 48x48px. Adequate spacing should be maintained between links. This helps users avoid accidental taps on touchscreens.
