HTTPS và SEO: Tại sao HTTPS là yếu tố quan trọng giúp website của bạn lên top Google? 🔒🚀

Trong thế giới số hiện đại, HTPPS và SEO không thể tách rời. Nếu bạn đang sở hữu một website, bạn cần hiểu rằng HTTPS không chỉ là một lớp bảo mật, mà còn là một yếu tố SEO quan trọng.

Google đã chính thức xác nhận HTTPS là một tín hiệu xếp hạng trong thuật toán tìm kiếm. Vậy HTTPS là gì? Nó ảnh hưởng như thế nào đến SEO và làm sao để chuyển đổi từ HTTP sang HTTPS mà không mất thứ hạng? Hãy cùng Lê Khang Digital tìm hiểu ngay!

🌐 HTTP vs. HTTPS: Điểm khác biệt là gì?

1️⃣ HTTP là gì?

HTTP (HyperText Transfer Protocol) là giao thức giúp truyền tải dữ liệu giữa máy chủ và trình duyệt của người dùng. Nó được sử dụng phổ biến từ những ngày đầu của Internet. Tuy nhiên, HTTP không có cơ chế mã hóa dữ liệu, khiến thông tin người dùng có nguy cơ bị đánh cắp.

2️⃣ HTTPS là gì?

HTTPS (HyperText Transfer Protocol Secure) là phiên bản bảo mật của HTTP, sử dụng SSL/TLS để mã hóa dữ liệu trước khi gửi đi. Khi website sử dụng HTTPS, trình duyệt sẽ hiển thị biểu tượng 🔒 Secure, giúp người dùng an tâm hơn khi truy cập.

🎯 Lợi ích chính của HTTPS:

✅ Mã hóa dữ liệu: Bảo vệ thông tin người dùng khỏi hacker. ✅ Tăng độ tin cậy: Trình duyệt sẽ không cảnh báo "Không an toàn". ✅ Tối ưu SEO: Google ưu tiên các trang web có HTTPS.

📈 HTTPS ảnh hưởng đến SEO như thế nào?

1️⃣ Google chính thức ưu tiên HTTPS trong xếp hạng tìm kiếm

Google đã xác nhận rằng HTTPS là một yếu tố xếp hạng, và các trang web sử dụng HTTPS có khả năng xếp hạng cao hơn so với HTTP.

🔥 Thực tế: Một nghiên cứu của Moz cho thấy hơn 50% trang web trên trang đầu tiên của Google đều sử dụng HTTPS.

2️⃣ Tăng độ tin cậy & trải nghiệm người dùng

🔹 Khi truy cập vào một trang web HTTP, trình duyệt Chrome sẽ hiển thị cảnh báo "Không an toàn". Điều này khiến người dùng mất niềm tin và rời bỏ trang ngay lập tức.

🔹 Một trang web có HTTPS giúp người dùng cảm thấy an toàn hơn, từ đó tăng thời gian ở lại trang và giảm tỷ lệ thoát trang (Bounce Rate).

3️⃣ Bảo vệ dữ liệu người dùng khỏi hacker

HTTPS giúp mã hóa dữ liệu, ngăn chặn các cuộc tấn công Man-in-the-Middle (MITM), giúp bảo vệ thông tin như: 🔹 Mật khẩu & thông tin đăng nhập. 🔹 Số thẻ tín dụng & thông tin cá nhân.

4️⃣ Cải thiện hiệu suất quảng cáo Google Ads

Nếu bạn chạy quảng cáo Google Ads, HTTPS là bắt buộc. ✅ Google ưu tiên các trang đích có HTTPS. ✅ Giảm chi phí quảng cáo (CPC) do điểm chất lượng (Quality Score) cao hơn. ✅ Tăng tỷ lệ chuyển đổi (Conversion Rate).

5️⃣ Tăng tốc độ tải trang với HTTP/2

HTTP/2, phiên bản mới của giao thức HTTP, yêu cầu HTTPS để hoạt động. HTTP/2 giúp tăng tốc độ tải trang bằng cách: 🚀 Cho phép tải nhiều file cùng lúc. 🚀 Giảm độ trễ mạng. 🚀 Cải thiện hiệu suất website.

6️⃣ Hỗ trợ AMP & tối ưu hiển thị trên di động

Nếu bạn muốn triển khai AMP (Accelerated Mobile Pages) để cải thiện tốc độ trên di động, bạn bắt buộc phải sử dụng HTTPS.

🔄 Hướng dẫn chuyển từ HTTP sang HTTPS đúng cách

Bạn đã sẵn sàng chuyển sang HTTPS nhưng lo ngại ảnh hưởng đến thứ hạng SEO? Đừng lo, làm theo hướng dẫn này để đảm bảo mọi thứ diễn ra suôn sẻ!

📌 Bước 1: Mua chứng chỉ SSL/TLS

Bạn có thể chọn các loại chứng chỉ SSL: 🔹 Let’s Encrypt (Miễn phí): Phù hợp cho blog, website cá nhân. 🔹 Comodo, GlobalSign, DigiCert (Trả phí): Bảo mật mạnh hơn, phù hợp cho website thương mại điện tử.

📌 Bước 2: Cài đặt chứng chỉ SSL trên máy chủ

Việc cài đặt SSL sẽ khác nhau tùy vào loại hosting: 🔹 Apache: Cấu hình file .htaccess. 🔹 Nginx: Chỉnh sửa file cấu hình .conf. 🔹 WordPress: Dùng plugin Really Simple SSL để tự động chuyển đổi.

📌 Bước 3: Cập nhật toàn bộ liên kết nội bộ

🔹 Kiểm tra tất cả các URL trong trang web và thay đổi từ HTTP → HTTPS. 🔹 Dùng công cụ Screaming Frog hoặc Ahrefs để tìm và sửa các liên kết cũ.

📌 Bước 4: Thiết lập chuyển hướng 301

Chuyển hướng 301 giúp: ✅ Giữ nguyên giá trị SEO của các trang HTTP cũ. ✅ Thông báo với Google rằng website đã chuyển sang HTTPS.

Ví dụ chuyển hướng 301 trên Apache:

apache

Sao chépChỉnh sửa

RewriteEngine On RewriteCond %{HTTPS} !=on RewriteRule ^(.*)$ https://yourwebsite.com/$1 [R=301,L]

📌 Bước 5: Cập nhật Google Search Console & Google Analytics

The first step is sourcing the actual physical server your site will run on. You can rent a VPS or dedicated server from providers like :

DigitalOcean

Vultr

Linode

AWS

Google Cloud

VPS plans start around $10/month for basic setups. Dedicated servers are more expensive but give you sole access to the underlying hardware.

Make sure to choose a provider with servers near your audience for fastest performance.

Software Setup & Configuration

Once you have your VPS or dedicated box, it's time to set up the software powering your WordPress site :

Install a Linux distro like Ubuntu or CentOS

Configure the LAMP or LEMP stack (Linux, Apache/Nginx, MySQL, PHP)

Tweak the Apache/Nginx config for optimal WordPress performance

Secure MySQL, PHP, and other services

Install caching like Varnish and php-fpm

Set up a control panel like CPanel for easier management

This process requires deep Linux server and WordPress expertise. But the payoff is getting everything finely tuned for your particular site's needs.

Ongoing Management

Server setup is just the beginning. With self-hosted infrastructure, you must handle all ongoing management and maintenance yourself including :

OS and software updates

Security patching

WordPress core, plugin and theme updates

Backups and disaster recovery

Monitoring uptime and performance

Optimizing the stack as needed

Troubleshooting any issues that arise

The work never stops when you self-host! You must stay vigilant to keep your site running smoothly.

The Pros of Self-Hosted WordPress

Let's recap the biggest benefits of rolling your own WordPress hosting environment :

Total control: You make all hosting decisions to perfectly fit your specific needs.

Flexibility and customization: You can configure server software like PHP, MySQL, Nginx however you want.

Cost savings: Once optimized, self-hosted sites can cost less per month than managed WordPress hosting.

Performance and scalability: You can fully optimize and tune the server for your particular site.

No vendor lock-in: You can easily migrate between different server providers.

When to Consider Self-Hosted WordPress

Self-hosted infrastructure makes the most sense for :

Developers and engineers with server administration expertise

Sites that require total control over the stack

Companies with large budgets for hosting costs

Complex sites anticipating high traffic and load

Businesses wanting to scale sites across multiple servers

Anyone running advanced stack configurations like HHVM or custom LEMP

Potential Downsides of Self-Hosted

Self-hosting isn't all sunshine and rainbows. Here are the biggest challenges to weigh :

Time investment: Server setup and management is extremely time consuming and complex.

Technical skill required: You must have significant sysadmin, DevOps, and WordPress expertise.

Maintenance overhead: OS, software, and WordPress updates are a never-ending chore.

Security liability: You're fully responsible for protecting against threats and vulnerabilities.

No support: If (and when) problems occur, you're on your own to fix them.

Higher learning curve: Be prepared to invest many hours mastering server configuration.

As you can see, self-managed WordPress hosting is definitely not for the faint of heart!

Managed WordPress Hosting Overview

In contrast to the DIY approach of self-hosting, managed WordPress hosting providers take care of everything related to your infrastructure and server environment.

Companies like WordPress Engine, Kinsta, and Pagely handle all aspects like :

Server provisioning

WordPress installation

Software setup and configuration

Ongoing maintenance and management

Updates

Security

Backups

Caching and performance optimization

24/7 WordPress technical support

This hands-off approach allows you to focus entirely on your site content and not worry about hosting headaches.

How Managed WordPress Hosting Works

Let's look at how managed WordPress hosting operates under the hood :

Optimized Infrastructure

Hosts like WordPress Engine build their architecture specifically for WordPress. This includes :

High-performance server hardware

CDNs for blazing fast static file delivery

Multiple app and database server clusters

Batched updates and maintenance for minimal downtime

Geographic redundancy to keep sites always online

The result is WordPress performance and reliability far exceeding what most self-hosted setups can achieve.

Hardened Security

Managed hosts implement numerous security enhancements like :

Automated malware detection and removal

DDoS protection

Advanced firewalls and access control lists

Ongoing vulnerability scanning and patching

Regular penetration testing

Forced SSL to encrypt all connections

Your site stays locked down and safe from threats.

Hassle-Free Maintenance

Hosts take complete ownership of mundane but critical tasks like :

OS and software updates

Daily offsite cloud backups

WordPress core and plugin updates

Content delivery network (CDN) config

SMTP email delivery management

Performance monitoring and optimization

You'll never have to worry about this stuff again!

White-Glove Support

Managed WordPress hosting providers staff teams of WordPress experts available 24/7 to help with :

Site migrations

Configuration questions

Troubleshooting plugin and theme conflicts

Diagnosing performance problems

Outages and emergency response

Any other issues that come up

For those times when you need a lifeline, support is just a phone call or support ticket away.

The Benefits of Managed WordPress Hosting

Let's recap the biggest perks of handing off hosting management :

No technical skill required: You don't need any sysadmin or DevOps expertise.

Blazing fast performance: Providers optimize WordPress speed right out of the box.

Enhanced security: Hardened environments keep your data safe.

99.9% or better uptime: Clustering and redundancy eliminate downtime.

Automatic updates: WordPress and plugins stay up to date automatically.

Time savings: No need to manage infrastructure yourself.

24/7 expert support: Get help anytime you need it.

Daily backups: Never lose data or worry about disaster recovery.

When to Consider Managed WordPress Hosting

Managed WordPress hosting is a perfect fit for :

Bloggers who want to focus on content instead of backend complexity

Ecommerce sites and client projects needing rock-solid reliability

Publishers and media companies with large audiences

Regulated businesses requiring security and compliance

Sites where fast performance and SEO are critical

Anyone looking to offload infrastructure management

Potential Downsides of Managed Hosting

Managed WordPress hosting isn't without some tradeoffs :

Less control and flexibility: You must accept the provider's system configurations.

Limited customization: Some hosts restrict plugins or forbid code changes.

Higher cost: Managed WordPress hosting is more expensive than self-hosting.

Vendor lock-in: Migrating between managed hosts is harder than switching servers yourself.

Overkill for simple sites: Lots of overhead and cost for basic blogs.

Hybrid Hosting: Getting the Best of Both Worlds

If you like aspects of both self-hosted and fully managed WordPress hosting, hybrid options try to give you the best of both worlds.

Platforms like Cloudways, Kinsta MyKinsta, and Pantheon combine easy WordPress setup and management with more flexibility over your environment.

For example, Cloudways still handles core infrastructure like scaling and security. But you get more configuration control, choice of server location, and the ability to install whatever software you need.

Hybrid platforms can be a great middle ground. Evaluate options like :

Cloudways

Kinsta MyKinsta

Pantheon

Pagely

WordPress-Engine Genesis

DreamPress

The downside is hybrid hosts tend to offer less optimization and fewer enterprise features out of the box compared to true premium managed WordPress hosting.

Migrating Between Environments

One final thing to note - don't get analysis paralysis worrying about picking the "perfect" option upfront.

If your needs change down the road, you can always migrate from self-hosted WordPress to managed hosting or vice versa.

Just make sure to choose a platform that provides tools to make the transition as smooth as possible.

For example, hosts like WordPress Engine offer a migration service to safely transfer your site. And they provide instructions on exporting your database and files for self-migration.

The takeaway? Don't let hosting decisions delay actually launching your WordPress site! Pick an environment, get up and running, and optimize later.

Which is Right for You?

So which type of WordPress hosting should you choose? Here are some final recommendations based on common use cases :

For Bloggers

Go with managed WordPress hosting. The last thing you want is dealing with servers and infrastructure when you should be focused on creating content.

For Developers

Self-hosted is likely the best fit. You'll want access and control to run whatever stack and configurations you need.

For Ecommerce Sites

Managed hosting is ideal. You'll benefit from optimized performance, tight security, and expert support for your business.

For Enterprise Companies

Either self-hosted or managed enterprise-grade hosting. For large complex sites, leave it to the experts.

When In Doubt

You really can't go wrong starting with managed WordPress hosting, even as a developer. Let the provider handle infrastructure so you can focus on building an awesome site!

Don't Stress, Just Start!

I know that was a boatload of information to process. But don't overthink the self-hosted vs managed WordPress hosting decision.

The most important thing is to get your site launched and start sharing your passion with the world! You can always change environments later if you want more control or less complexity.

With the right host and a well-crafted strategy, you can build a WordPress site that achieves all your goals and visions. So take a deep breath, review the options, and make the best decision for today.

The perfect WordPress hosting fit for you is just a signup form away. It's time to stop dreaming and start doing - now get out there and start that site!

Apache vs Nginx – Which is best?

Web servers are software tools that store, process and deliver web pages to clients. Apache (refers to the ‘Apache HTTP server) is secure, open-source, web server application designed for the modern operating system. It was developed by Apache Software Foundation. Apache can be downloaded at no cost. Nginx is lightweight, open-source HTTP and reverse proxy server and also an IMAP/POP3 proxy server.

Working of Apache

In order to handle additional connections, Apache creates threads and processes. The server can be configured by the administrator to control the maximum number of allowable process. Too many process exhaust memory and also apache refuses additional connection when the limit of the process is reached. Apache is flexible in terms of how it processes web requests. This is based on the Multi-Processing Module (MPM) used. The three main Apache MPMs are Process (Prefork) MPM, Worker MPM, and Event MPM.

Working of Nginx

Nginx works differently than Apache. Nginx does not setup new process for each web request, instead, the administrator configures how many worker processes to create for main Nginx process. Thousands of concurrent connections can be handled by each worker. To read data from disk, Nginx spins off cache loader and cache manager processes and load it into the cache and expire it from the cache when directed. Nginx can act as a reverse proxy server for TCP, UDP, HTTP, HTTPS, SMTP, POP3, and IMAP protocols. It can also act as a load balancer and an HTTP cache. Nginx uses a single-thread to handle the web server connections.

Strengths of Apache

Apache provides a wide range of built-in support.

Support for the latest HTTP 1.1 protocol.

Simple, powerful file-based configuration.

Support virtual hosts, PHP scripting, Java Servlet, and JSP. Support for Secured Socket Layer (SSL).

Apache has extensible Plugin Architecture.

Weaknesses of Apache

Performance and scalability issues.

Slows down under load.

Strengths of Nginx

Lightweight and able to handle more than 10,000 simultaneous connections.

Takes less memory and other resources.

Reverse proxy with caching.

Load balancing and fault tolerance.Embedded Perl scripting.

Weaknesses of Nginx

Lack of built-in support for Python and Ruby.

Nginx Plus version is not free.

Performance

Apache can handle static content using its conventional file-based methods. It can also serve the dynamic content by embedding a processor of the language in question into each of its worker requests. Nginx does not have any ability to process dynamic content natively but it serves static content much faster than Apache. NGINX is about two times faster and consumes a bit less memory (4%).

Security

Even though both apache and Nginx have a secure code base, both get stuck by security vulnerabilities. Comparing both, Nginx is slightly more secure than Apache with its centralized single configuration management.

Operating System

Apache has full support for Microsoft Windows and runs on all kinds of Unix-like systems. Even though Nginx has support for windows, its windows performance is not as strong as other platforms.

Apache vs Nginx Comparison

Apache is easier to configure than Nginx configuration is not easy.

In comparison to Nginx, Apache has excellent documentation.

Event-driven Architecture (EDA) is used by nginx whereas Apache uses process-driven architecture.

Nginx has non-blocking nature while Apache has blocking architecture.

Nginx uses Single-thread that means that it doesn’t create a new process for a new request. But in Apache, a new process is created for a new request.

Nginx has a very low memory consumption for a static page but, in case of Apache, memory consumption is high because of the requirement of creating a new process for each request.

Nginx is extremely fast as compared to Apache when it comes to serving static pages.

Nginx lacks the support of operating systems such as OpenVMS and IBM, but Apache supports the complete range of operating systems.

As Nginx comes up with required core features, it is much lighter than Apache
