能否利用canonical標(biāo)簽陷害競(jìng)爭(zhēng)對(duì)手？

不能。Canonical標(biāo)簽的作用是幫助搜索引擎正確識(shí)別源代碼當(dāng)中只有部分網(wǎng)頁(yè)上相同內(nèi)容的頁(yè)面，它不能用于欺詐或破壞搜索引擎算法。Canonical標(biāo)簽可以幫助提高搜索排名，但它不能損害競(jìng)爭(zhēng)對(duì)手或陷害競(jìng)爭(zhēng)對(duì)手。

相對(duì)路徑的優(yōu)點(diǎn)和缺點(diǎn)

相對(duì)路徑的優(yōu)點(diǎn)是：1.節(jié)省代碼。2.移動(dòng)內(nèi)容比較容易，不用更新其他頁(yè)面上的鏈接。3.在測(cè)試服務(wù)器上進(jìn)行測(cè)試也比較容易。相對(duì)路徑的缺點(diǎn)是：1.頁(yè)面移動(dòng)位置，里面鏈接可能需要改動(dòng)。2.被抄襲和采集對(duì)網(wǎng)站沒有任何益處。很多采集軟件其實(shí)是可以自動(dòng)鑒別絕對(duì)路徑和相對(duì)路徑的，所以使用絕對(duì)路徑有助于自己的鏈接也被抄襲到采集網(wǎng)站上，只在某些情況下有效。3.搜索引擎解析URL時(shí)可能出錯(cuò)，不能正確讀取頁(yè)面上的鏈接UR

sitemap：如何讓搜索引擎抓取到所有頁(yè)面

| sitemap是什么？● 網(wǎng)站地圖/鏈接集合，把網(wǎng)站所有的URL放在一個(gè)文件內(nèi)，方便搜索引擎爬取到。| 如何制作sitemap？● 小型網(wǎng)站采用txt格式的sitemap● 大中型網(wǎng)站采用xml格式的sitemap● 工具：老虎sitemap| 制作sitemap注意事項(xiàng)1. 文件格式為TXT或xml，普通企業(yè)官網(wǎng)TXT即可，大型網(wǎng)站可使用xml；2. 按時(shí)間倒序排列；3. 每周更新，最好每天

如何設(shè)置canonical標(biāo)簽

canonical標(biāo)簽跟301轉(zhuǎn)向的性質(zhì)差不多，區(qū)別在于用戶不會(huì)被轉(zhuǎn)向，還是停留在原本的頁(yè)面上，但搜索引擎會(huì)把它當(dāng)做301轉(zhuǎn)向處理，把頁(yè)面的權(quán)重集中到標(biāo)簽中所指的規(guī)范網(wǎng)頁(yè)上。canonical標(biāo)簽如何設(shè)置1、在HTML代碼的head里添加rel="canonical",不能添加多個(gè)，否則搜索引擎會(huì)認(rèn)為是無效的canonical標(biāo)簽。2、注意href里的地址不能是死鏈，錯(cuò)誤頁(yè)或者

能否利用canonical標(biāo)簽陷害競(jìng)爭(zhēng)對(duì)手？

今天再介紹一個(gè)黑帽負(fù)面SEO的想法：利用canonical標(biāo)簽陷害競(jìng)爭(zhēng)對(duì)手。聊黑帽SEO絕不是建議讀者做黑帽，優(yōu)化正規(guī)網(wǎng)站的還是盡量別嘗試，風(fēng)險(xiǎn)很大。但了解黑帽SEO方法，一是開拓思路，第二更重要的是，防范別人用負(fù)面SEO方法陷害自己。站長(zhǎng)們認(rèn)真觀察的話一定會(huì)發(fā)現(xiàn)，負(fù)面SEO的嘗試是一直在發(fā)生的。我這個(gè)小小的、誰(shuí)也不得罪的SEO博客都經(jīng)常被人制造巨量垃圾鏈接、制造大量敏感詞搜索頁(yè)面、刷跳出率等等，
