鏈接的建設要與目的網站具有相關性
The construction of links should be relevant to the target website
2、指向目的網站的鏈接必須是用戶心甘情愿給予的鏈接 （這點最為重要）
2. The link to the destination website must be willingly provided by the user (this is the most important)
只要滿足以上兩個條件的鏈接對網站優化排名提升有重要作用。
As long as the links that meet the above two conditions play an important role in website optimization and ranking improvement.
但是在今天還是有很多站長為了獲取對方的優質鏈接真是不擇手段，相信很多做SEO的朋友都遇到過這樣的情況如對于利用一個權重較高的網站來與你的網站進行交換鏈接，你看見他的權重是5，而你的權重是3不明白的以為自己站到了便宜。
But today, there are still many webmasters who resort to any means to obtain high-quality links from others. I believe many friends who do SEO have encountered such situations, such as using a website with a higher weight to exchange links with your website. When you see that their weight is 5, and your weight is 3, you may think that you have gained an advantage.
其實萬萬沒有想到的是權重為5的站點是造假的。或你的鏈接在對方網站根本不具有權重傳遞的價值等，這就是今天楊子與大家分享的鏈接作弊。
What I never expected was that sites with a weight of 5 were fake. Or your link may not have any weight transmission value on the other party's website, which is the link cheating that Yang Zi shared with everyone today.
下面從以下幾點來與大家共同學習分享鏈接作弊的幾種形式：
Below, we will learn and share several forms of link cheating with everyone from the following points:
一、通過JS代碼輸出友情連接
1、 Output friendship connections through JS code
搜索引擎對于JS代碼里面的內容根本不識別，因此如果對方的友情鏈接是JS代碼輸出，則對你的網站完全達不到權重傳遞的效果，就對方而言還得到了你的一個單項鏈接，當然再你們兩個進行交換之后對方也會截圖給你看，然后讓你去點擊一樣可以跳轉到你的網站，其實這樣的鏈接對你的網站沒有一點意義。
Search engines do not recognize the content in JS code at all, so if the other party's friendship link is output by JS code, it cannot achieve the effect of weight transfer to your website. As for the other party, they have also received a single link from you. Of course, after you exchange the two, the other party will also take a screenshot for you to see, and then ask you to click it to jump to your website. In fact, such a link has no meaning to your website.
