Lab Checking dead links

W3C Link Check 可以檢查 dead links, 而且只要輸入首頁,
就可以依據指定深度自動向下檢查, 而且也可以檢查對外連結(外站).

Link Checker 首先要設定檢查深度(Check linked documents recursively, recursion depth=?), 如果沒有設定, 它就只有檢查首頁.
因此如果出現 deadlink, 就是在首頁.

如果你設定檢查深度, 它就會逐一檢查此深度內的每一頁,
在檢查某一頁開始時, 它會先顯示現正在檢查的 URL, 然後
在逐一爬行該頁內每個 link.


報表輸出很漂亮. 請參閱

請檢查三個你最常使用的網站, 看看連結的品質如何?
紀錄有錯誤連結 (HTTP Error 404) 的次數.
