WordPress, as one of the world's most popular website building systems, is renowned for its ease of use and flexibility, but "slow and easy to be attacked" is also a pain point often encountered by novices. In practice, how to make WordPress website both fast and secure? This requires a set of systematic optimization ideas and practical skills, not only to improve user experience, reduce the bounce rate, but also help SEO rankings and traffic growth. In this article, from a practical point of view, progressive analysis, efficiently explain the WordPress site acceleration and security optimization of the whole process.
First, why is acceleration and security equally important?
- Fast access speed, the page opens in seconds, the visitor stays for a long time, the conversion rate is high.
- The website is safe and reliable, reducing black attacks or data loss, and reducing operational risks.
- Search engines clearly incorporate speed and security into the ranking algorithm, affecting traffic and weight.
If you only pay attention to the appearance or content and ignore the speed and security, the operational effect of the site is often greatly reduced.
Second, the core direction and plug-in program comparison
| Optimization direction | Recommended practices | Main plug-ins or methods | Enhancement effect |
|---|---|---|---|
| CDN acceleration | Select global acceleration nodes | Cloudflare, Tencent Cloud CDN | Speed up loading by 30%~90 |
| Page Cache | Full Site/Page Cache | WP Super Cache, LiteSpeed | Seconds effect, save server |
| Image Optimization | Batch compression, lazy loading | Smush, ShortPixel | Smoother page |
| Source Code Streamlining | Remove useless code, compress scripts | Autoptimize, WP Rocket | Faster loading |
| Malicious Protection | Firewall, blacklist, limit login attempts | Wordfence, iThemes Security | Anti-bursting, anti-trojanization |
| Regular backups | Automatic backups, cloud storage | UpdraftPlus, VaultPress | Backup and Restore |
| SSL encryption | One-click HTTPS configuration | Let's Encrypt, Cloudflare SSL | Data security, enhance the sense of trust |
Third, accelerate the optimization of detailed practice
1. CDN acceleration and static resources external links
- Register for a CDN platform account (free of charge, such as Cloudflare, domestic options Tencent, AliCloud)
- Switch DNS resolution to CDN, and automatically distribute the content of the whole site to the global nodes.
- Configure caching of static resources (images, JS, CSS, etc.) to improve local and overseas access speed.
2. Installation of caching and optimization plug-ins
- Background → Plug-ins, search and install such as WP Super Cache, LiteSpeed Cache.
- Enable static page caching to reduce frequent database calls.
- Cooperate with object caching and browser caching to improve the speed of multi-visitor concurrency
3. Image and media resource optimization
- Compress images with external tools (e.g. TinyPNG) before uploading.
- Enable plugins such as Smush or ShortPixel to automatically batch compress and lazy load.
- Replace traditional .png/.jpg with .webp format, better compatibility and smaller footprint
4. Streamlined source code and scripts
- Autoptimize plugin automatically compresses JS/CSS/HTML.
- Remove unused widgets/shortcodes to reduce the number of requests.
- Reasonable use of third-party fonts and libraries to prevent loading failures slowing down the whole page.
Fourth, security reinforcement step-by-step details
1. Basic settings security
- Avoid using the default admin user name for the background account.
- Strong password + two-step verification, regular modification
- Limit the number of login errors to prevent violent break-in
2. Firewall and anomaly detection
- Activate Wordfence and other protection plug-ins to block malicious access and injection in real time.
- Customize the login path such as /wp-admin to prevent batch attacks by machines.
- Enable email alerts to respond to abnormal operations as soon as they are discovered.
3. Regular backup and recovery policy
- Enable plug-ins such as UpdraftPlus to realize daily/weekly/customized automatic backup.
- Synchronize database and files with cloud storage to ensure zero data loss when local server is attacked.
- Regularly test the backup and recovery process to prevent the disaster recovery program from being "useless".
4. SSL encryption
- One-click HTTPS with Let's Encrypt free certificate.
- Background mandatory SSL access to prevent traffic hijacking.

| Frequently Asked Questions | Recommended solution direction |
|---|---|
| Will installing multiple acceleration plug-ins conflict? | Avoid coexistence of the same type of caching plug-ins, it is recommended to choose one of LiteSpeed or Super Cache. |
| How to judge the effect of hosting and CDN? | Use Ping/GTmetrix/Baidu webmaster speed test to compare the smoothness between on and off. |
| How safe is free CDN? | Cloudflare and other big international companies have DDoS protection, it is safe for compliance purposes, but you can choose paid CDN for important business. |
| What should I do if I am hacked? | Stop the website first, check and kill the Trojan files, use the recent backup to restore with one click, and upgrade all the passwords and plug-ins at the same time. |
| HTTPS causes some resources to be "pseudo-secure"? | Use SSL tools to detect mixed content, and update all resource links to begin with https. |
