在網(wǎng)站SEO優(yōu)化工作中，外鏈的作用不言而喻，優(yōu)質(zhì)的外鏈可以為網(wǎng)站帶來(lái)很好的優(yōu)化效果。如果沒(méi)有建設(shè)必要的外鏈，那么搜索引擎可能就無(wú)法快速識(shí)別你的網(wǎng)站，因此SEO優(yōu)化和外鏈的關(guān)系非常密切。那么，常見(jiàn)的外鏈建設(shè)方法有哪些呢？

In website SEO optimization work, outside the chain effect is self-evident, high-quality outside the chain can bring very good optimization effect for website. If there is no construction necessary outside the chain, then the search engine may be unable to quickly identify your website, so SEO optimization and outer chain very closely. So, what are common outside the chain construction method? 

　　第一，在自己網(wǎng)站建設(shè)外鏈

First, in his own construction site outside the chain 

　　對(duì)于沒(méi)有PR值，收錄也不理想的新站來(lái)說(shuō)，想要找友情鏈接是很不容易的。因此，新站可以先在自己的網(wǎng)站做幾個(gè)鏈接，在PR值有所提升、收錄也比較正常之后，再開(kāi)始做友情鏈接。

For no PR values, the collection is not ideal new stations, it is not easy to want to look for links. New sites, therefore, to do some link on his website, the PR value increased, included are normal, then start to do link. 

　　第二，在論壇博客下面留言

Second, in the BBS blog comments below 

　　在一些論壇和博客的下面加上自己的網(wǎng)站地址也是最常見(jiàn)的外部鏈接方法，但是不能一味地發(fā)鏈接，首先需要先到論壇發(fā)言，并提出有建設(shè)性的觀點(diǎn)和意見(jiàn)，這樣才會(huì)吸引別人的關(guān)注，后面發(fā)鏈接也會(huì)比較簡(jiǎn)單。要不很容易被刪帖。

In some BBS and blogs with your website address below which is the most common method of external links, but not blindly send links, first need to speak to the BBS, and put forward constructive views and opinions, this will attract the attention of others, the link will be relatively simple. Otherwise it is easy to delete. 

　　第三，檢查競(jìng)爭(zhēng)對(duì)手的外鏈

Third, the inspection for the chain of the competition 

　　"知己知彼才能百戰(zhàn)不殆"，分析競(jìng)爭(zhēng)對(duì)手網(wǎng)站的外部鏈接建設(shè)情況對(duì)于我們自己來(lái)說(shuō)非常重要，一些很強(qiáng)的競(jìng)爭(zhēng)對(duì)手往往有成百上千的外鏈，我們可以利用一定的技術(shù)把競(jìng)爭(zhēng)對(duì)手的外鏈都看一遍，找到其中的好來(lái)源，如果我們能把競(jìng)爭(zhēng)對(duì)手所具備的外鏈也都得到，再加上其他渠道獲得的競(jìng)爭(zhēng)對(duì)手沒(méi)有的外部鏈接，那么我們網(wǎng)站的排名與流量必定會(huì)超越競(jìng)爭(zhēng)對(duì)手。

"Enemy and know yourself an argument," analysis of competitors website construction of external links is very important for our own, some very strong competitors often have hundreds of thousands of outer chain, we can use a certain technology to rival the outer chain look again, find a good source of, if we can put the competitors also have been outside of the chain, plus other sources of competitors without external links, so our site's ranking and traffic will surpass competitors.
