链接的建设要与目的网站具有相关性
The construction of links should be relevant to the target website
2、指向目的网站的链接必须是用户心甘情愿给予的链接 （这点最为重要）
2. The link to the destination website must be willingly provided by the user (this is the most important)
只要满足以上两个条件的链接对网站优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.
但是在今天还是有很多站长为了获取对方的优质链接真是不择手段，相信很多做SEO的朋友都遇到过这样的情况如对于利用一个权重较高的网站来与你的网站进行交换链接，你看见他的权重是5，而你的权重是3不明白的以为自己站到了便宜。
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.
其实万万没有想到的是权重为5的站点是造假的。或你的链接在对方网站根本不具有权重传递的价值等，这就是今天杨子与大家分享的链接作弊。
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.
下面从以下几点来与大家共同学习分享链接作弊的几种形式：
Below, we will learn and share several forms of link cheating with everyone from the following points:
一、通过JS代码输出友情连接
1、 Output friendship connections through JS code
搜索引擎对于JS代码里面的内容根本不识别，因此如果对方的友情链接是JS代码输出，则对你的网站完全达不到权重传递的效果，就对方而言还得到了你的一个单项链接，当然再你们两个进行交换之后对方也会截图给你看，然后让你去点击一样可以跳转到你的网站，其实这样的链接对你的网站没有一点意义。
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.
