網站安全性與 SEO 息息相關,若網站存在安全漏洞,可能導致搜尋排名下降,甚至被 Google 移除索引。以下是常見的網站安全性問題及對應解決方案。
- HTTPS 加密與網站信任度 Google 強調 HTTPS 的重要性,未使用 HTTPS 的網站可能被標示為「不安全」,影響用戶信任與 SEO 排名。解決方案:
安裝 SSL/TLS 憑證,將網站升級為 HTTPS,確保數據加密。
使用 Let’s Encrypt 等免費 SSL 方案,減少成本。
- 惡意軟體與駭客攻擊 若網站遭受惡意軟體感染或駭客攻擊,Google 可能對其降權或移除索引。解決方案:
使用網站安全外掛(如 Wordfence、Sucuri)定期掃描網站漏洞。
監控網站變更,檢查是否有未經授權的檔案或異常流量。
限制管理員存取權限,降低入侵風險。
- DDoS 攻擊與伺服器防護 DDoS 攻擊會癱瘓網站,影響用戶體驗與 SEO。解決方案:
使用 CDN 服務(如 Cloudflare、Akamai)來減少惡意流量影響。
啟用 防火牆(WAF),阻擋惡意請求。
與 網站主機商確認安全性措施,如異常流量監測與自動封鎖機制。
- 登入安全性與用戶資料保護 駭客可透過弱密碼或 SQL Injection 取得用戶資料,影響網站信譽與 SEO。解決方案:
啟用 雙重驗證(2FA),提高登入安全性。
使用 強密碼策略,避免使用簡單密碼。
定期更新 WordPress、插件與伺服器軟體,以修補安全漏洞。
