織夢在發(fā)布文章的時候，關鍵字替換設計的不是很理想：

　　1.發(fā)布文章的時候必須在“關鍵字”文本框中輸入要替換的關鍵字才能被替換；西安哪家網(wǎng)站制作公司做的比較好,西安做網(wǎng)站推薦閱讀>>> 西安網(wǎng)站建設：網(wǎng)站關鍵詞競爭程度怎么判斷,

　　2.如果兩個關鍵字有包含關系時，替換時就會產(chǎn)生重疊替換；

　　針對以上問題把問題修改成按關鍵字的字節(jié)數(shù)大小替換，例如：有兩個關鍵字“做網(wǎng)站”“做網(wǎng)站公司”那么就先替換做網(wǎng)站公司，再替換下文的做網(wǎng)站。做網(wǎng)站公司與做網(wǎng)站也不會重疊替換。西安建立網(wǎng)站,西安網(wǎng)站建設推薦閱讀>>> 西安網(wǎng)站建設，關鍵詞優(yōu)化的一些技巧,
